November 11th 2018 – At the going down of the sun…

At the eleventh hour on the eleventh day of the eleventh month 1918, the guns on the western front fell silent. Four years of war in which millions were either killed or wounded, towns and villages wiped from the map and the environment changed forever, had finally come to an end. All along the front line, men were soon to put down their arms and leave their trenches for home.

The war to end all wars had finally come to an end. During the last four years some 40 million people had been killed or wounded, many simply disappeared in the mud that bore no preference to consuming man or machine.

Back home, virtually no city, town, village or hamlet was left unscathed by the loss of those four years. Many who returned home were changed, psychologically many were wounded beyond repair.

Sadly, twenty years later, the world slipped into the abyss of war once more. A war that saw some of the most incredible horrors, one that saw the extreme capabilities of what man can do to his fellow-man. Across the world millions of innocent people were slaughtered under the guise of an ideology. An ideology that was determined to rid the world of anyone who was willing to speak out against that very same ideology.

Young men were transported thousands of miles to fight in environments completely alien to them. Many had never been beyond their own home town and yet here they were in foreign lands fighting a foe they had never even met.

The bravery and self-sacrifice of those young men  on the seas, on the land and in the air, go beyond anything we can offer as repayment today.

For nearly 80 years, the world has been at an uneasy rest, Korea, Vietnam, the Falklands, the Middle East, and the Far East, in almost every corner of the globe there has been a war in which our service men and women have been involved. The war to end all wars failed in its aim to bring peace to the world.

In this year, on the hundredth anniversary of the ending of the First World War along with the anniversary of the formation of the Royal Air Force, we remember those who laid down their lives in the fight for freedom. We remember those who fought for the right to free speech, for the right to be who you are and the right to live our lives in peace.

We will remember them…

Anthem for Doomed Youth

What passing-bells for these who die as cattle?
Only the monstrous anger of the guns.
Only the stuttering rifles’ rapid rattle
Can patter out their hasty orisons.
No mockeries now for them; no prayers nor bells,
Nor any voice of mourning save the choirs,
The shrill, demented choirs of wailing shells;
And bugles calling for them from sad shires.

What candles may be held to speed them all?
Not in the hands of boys, but in their eyes
Shall shine the holy glimmers of goodbyes.
The pallor of girls’ brows shall be their pall;
Their flowers the tenderness of patient minds,
And each slow dusk a drawing down of blinds.

RAF Scampton – What does the future hold?

Many in the aviation world were saddened and even shocked recently (24th July 2018) with the MOD’s announcement that RAF Scampton and RAF Linton-on-Ouse were to close, and the two sites sold off.

Whilst there seems to be little general objection to Linton-on-Ouse, there has been quite a backlash regarding the closure of RAF Scampton in Lincolnshire. Scampton is of course home to the RAF’s Red Arrows display team who moved in there around twenty years ago, but more famously, it was the home of 617 Squadron RAF otherwise known as ‘The Dambusters’ during the Second World War.

It is this that has primarily caused the huge backlash resulting in a petition and some quite heated social media ‘discussions’ over the closure. So what are the reasons behind such a move and what could the future hold for RAF Scampton?

Scampton has been under RAF ownership since the First World War, it is one of their oldest stations and has housed some 19 operational flying squadrons as well as a number of non-flying units during this time. The base was closed in 1996 and then again partially reopened for the storage and maintenance of aircraft, it was also at this point that it became home to the RAF’s Red Arrows. Currently the only other units stationed here are No.1 Air Control Centre and the Mobile Meteorological Unit.

No. 1 Air Control Centre was moved here from RAF Lossiemouth whilst upgrading work was undertaken on its site. They work in conjunction with, amongst others, RAF Boulmer to provide National and International air surveillance operations ready to deploy QRA Typhoons from either Lossiemouth or nearby Coningsby at a moments notice. They also provide support to international operations including those with the British Army and the Royal Navy.

The Mobile Meteorological Unit uses civilian operators (Reserves) to monitor weather conditions primarily for aviation related operations, but they can also assist in any operation where the weather may impact on the overall objective.

The Red Arrows (RAFAT) are perhaps the most famous of the world’s aircraft display teams, currently flying the BAE Hawk, in close formation flying displays that have spanned fifty-four years. The Red Arrows are famous the world over, with pilots undertaking a rigorous selection process and subsequent training programme, that sets them amongst the most elite pilots in the world.

These three units mean that there are around 600 people employed on the Scampton site, mainly armed forces personnel who will be moved with their various units to new postings when the move finally takes place. Some of these employees are civilian and live locally to the airfield.

The argument for closure.

The RAF has been under considerable pressure to reduce its costs whilst keeping a viable and effective force. The recent purchase of the F-35 Lightning to replace the now ageing Tornado, had a significant impact in the RAF’s overall budget. However, this was taken into consideration within the MOD’s strategy which aimed to reduce costs, streamline operations and reshape the RAF for the modern world. Notifications of these cuts were aired in the 2010 Strategic Defence & Security Review (SDSR) in which it was announced that the RAF would*1:

  • Reduce its manpower force by around 5,000 personnel to 33,000 by 2015;
  • Retain Tornado but remove Harrier from service in the
    transition to a future fast jet force of Typhoon and JSF;
  • Not bring into service the Nimrod MRA4;
  • Withdraw VC10 and the three variants of Tristar aircraft
    from 2013 as part of the transition towards the more capable
    A330 future strategic transport and tanker aircraft;
  • Withdraw the C-130 Hercules transport fleet 10 years earlier than planned to transition to the more capable and larger A400M;
  • Withdraw the Sentinel surveillance aircraft once it is no longer required to support operations in Afghanistan;
  • Rationalise the RAF estate (40% of which is over 50 years old)
VC 10 flypast 29/8/12

The VC-10 fly past over RAF Coningsby on August 29th 2012, prior to their withdrawal from service.

Whilst much of this criteria has already been met, the estates management review has yet to take full effect. A series of reviews and assessments have been carried out by relevant Government bodies in conjunction with personnel from the MOD. The Better Defence Estates strategy 2016 (which is part of the Defence Estate Optimisation Programme) focuses on streamlining the MOD’s estates: land, bases and housing by 30% by 2040. Only by doing this, will the MOD meet its SDSR commitment, saving £3bn by 2040, allowing £4bn to be invested over the next 10 years on over 40 separate sites.

A further Government commitment is to generate 55,000 new private homes, some of which will be for armed forces personnel (Service Families Accommodation, SFA), but most will be released to private housing ventures. Much of the land owned by the MOD (which covers 1.8% of the UK land mass), and in particular the RAF, has huge building potential and is therefore prime building land.

So far, the MOD has disposed of nine military sites, with a further ninety-one earmarked for closure. This doesn’t include Scampton or Linton-on-Ouse, but does include: Swansea Airport, Newtownards Airfield, RAF Colerne, RAF Henlow, RAF Halton and the three American bases at Molesworth, Mildenhall and Alconbury (currently occupied by USAF personnel).

The cost of maintaining one of these sites, is not cheap, and a considerable amount of money was spent on Scampton following the 2010 review, to resurface the runway to allow both the Red Arrows to operate from here and to keep the base in operational status should other units be posted here later on. However, the infrastructure remains a pre World War II design, the buildings and hangars dating back to the expansion period of the 1930s (as do Linton-on-Ouse’s) and therefore completely inadequate for today’s modern Air Force. In his deliverance of the ‘Better Defence Estate’ statement, the Parliamentary Under-Secretary of State for Defence, Mr Tobias Ellwood, said “The disposal of the site would offer better value for money and, crucially, better military capability by relocating the units based there“.

Considering other aspects of Scampton, the Museum of RAF Fire Fighting*2 was told to vacate their premises in 2017, they have since found alternative accommodation in Gainsborough and aim to be up and running very soon. There was also a renewed effort to bring airshows back to Lincolnshire after the Waddington shows were stopped following upgrade at RAF Waddington. The first, and so far only attempt, at Scampton in September 2017, made a loss even though 50,000 visitors passed through the gates over the two-day period. This was a huge drop in figures however, compared to the 170,000 previously attained at Waddington. A planned event for 2018 was postponed until 2019, but no firm decision has been made about the future viability of this event.

Sisters together

A further point to be considered is that of the local economy. Many argue that the base provides economic benefits to the local economy. Being only 600 personnel, this is quite a weak argument, unlike say Mildenhall that has 4,000 personnel contributing £219m (2013-14 figures) to its local economy.*3

So on the face of it, Scampton is ‘ideal’ for disposal, it is underused, located in an area already busy with aircraft activity (RAF Cranwell, RAF Waddington and RAF Coningsby are all nearby) and has an infrastructure suited for a private venture. The accommodation areas are mostly empty and those units based there are easily moved elsewhere, only the Red Arrows could prove a problem due to interference with other operational flying units.

The argument against closure.

However, that said, Scampton (more so than Linton-on-Ouse) has a huge historic value. Being a pre-war airfield it was vital for Bomber Command in the fight against Nazi Germany. Initially built with grass runways, these were improved upon with hard runways in the early war years, being extended to 10,000 feet later on in 1956, to be able to take the mighty Vulcan. This expansion led to extensive renovations including the re-sighting of the main Roman road (Ermine Street) that passes alongside the airfield. It is this extension that led to Scampton’s famous station badge of the bow and arrow. In 2016 Scampton celebrated its centenary and this year (2018) marks the 100th anniversary of the RAF.

The biggest factor in favour of keeping Scampton open are its historical, political and architectural aspects, the most famous being the presence of 617 (Dambusters) Sqn during the 1940s. A specialist squadron, formed under the leadership of Guy Gibson VC, DSO & Bar, DFC & Bar,  who led the 133 airmen in nineteen Lancasters in the famous attack against the dams of the Rhur valley on May 16th, 1943. In memory of this historic event, a museum was opened up showcasing a number of artefacts from the Dambusters including Guy Gibson’s office. Gibson’s dog ‘Nigger‘ is also buried in the grounds of Scampton, outside of what was Gibson’s office and many of the offices used by the squadron are also open for pre-arranged visits.

The names of those who took part in Operation ‘Chastise’

There are of course a number of other historical aspects to this site. Airmen from Scampton were awarded a greater number of honours that any other bomber airfield, including two Victoria Crosses and a George Cross in 1940 alone. The first 2,000 lb bomb was delivered by aircraft based at Scampton, and numerous raids were undertaken from here including its participation on the first 1,000 bomber raid.

Post war and Scampton played a major part in the Cold War, an airfield housing the Vulcan, an aircraft capable of carrying and delivering the Blue Steel stand-off nuclear missile, one of only two airfields that could complete such a task. In order to complete this role, further T2 hangars were added, the dispersals were modified and additional ancillary buildings erected for fuelling and avionics.

The four ‘C’ type hangars now Grade II listed (1st December 2005 – List entry Number: 1391594) are the only listed buildings on site, the Blue Steel maintenance shed being demolished in March 2004, before listing was made. In fact over recent years, many unused buildings have been gradually demolished: the pre-war parachute stores, the main station workshop outbuildings, the Vulcan simulator, parts of the medical centre and the Warrant Officers’ Quarters are all included.

The main reason for the listing of these hangars is their ‘Legacy’ record, and includes the attached stores, workshops and offices. These ‘C’ type hangars were built in the period 1936-1937 by J. H. Binge of the Air Ministry’s Directorate of Works and Buildings, to drawing number 5043/36, and signify the airfield as a bomber airfield. The sacrifice by Bomber Command was immense, some 55,000 aircrew were killed in operations and many came from airfields in and around Lincolnshire. Thus these hangars, as listed buildings, stand as unofficial memorials to those who never came back and in particular to those of 617 Sqn who gave the ultimate sacrifice. As listed buildings, they cannot easily be demolished and therefore must be retained in any future development whatever that may be. Even with these modifications having taken place, the general layout of the airfield, the road networks and most buildings are still the pre-war expansion period designs, little has changed here since those days of the late 1930s when Britain was expanding it national network of airfields.

A review of Britain’s airfields by English Heritage, classified Scampton (and Linton-on-Ouse) “as one of most complete surviving of our Airfields with Runways and Perimeter tracks” comparable with RAF West Raynham, RAF Finningley, and RAF Waddington. It is a prime example of an expansion period model, being built under Scheme B of the period and only one of four to be so. The architectural designs of the buildings significant in themselves, being a mix of neo-Georgian and concrete within its non-dispersed site. The shape and design of Scampton (and Linton-on-Ouse) are unique to this period in time, square with straight roads and grassed / tree areas to hide the accommodation and technical areas.

A further point is that there have been numerous archaeological investigations and finds on and around the airfield itself. These include: Prehistoric remains, Roman remains (the Roman road traverses part of the airfield), Anglo-Saxon burial sites, Medieval sites, post-medieval and modern warfare sites (WWI & II) that remain buried. Many of these have yet to be fully investigated and mapped, but it is thought that there are strong links to all of these periods in time.

So what are the possible options?

These are certainly strong advocates for keeping the station alive, however, the question then arises does this warrant the huge expense of maintaining an operational airfield without service personnel being present? Does it warrant the use of an operational airfield just for the Red Arrows? Even if the RAF were to stay here, which unit(s) could be brought in and at what cost to other airfields? Many would argue not, and if the RAF / MOD are to meet their commitment to both a leaner more efficient Air Force and the SDSR, then on paper surely Scampton must close.

However, there are a number of options open when Scampton is closed. The worse scenario is that the entire site is sold to housing / industrial development. In such cases the historical aspect of Scampton could be lost, the hangars turned into industrial units and the airfield removed completely. This, if it were to happen, would no doubt cause a huge backlash from many in the aviation field including the RAF itself, and is unlikely (in my opinion) to happen.

Since the announcement of the 2010 SDSR the future of Scampton has been under considerable debate, with numerous studies being completed on behalf of the RAF and Lincolnshire County Council. On December 15th, 2011*4, Parliament were notified of the suggestion that Scampton could be closed by 2014 following the merger of No 1 Air Control Centre and the Control and Reporting Centre at RAF Kirton-in-Lindsey , which also closed as a result. Both these units would then move to RAF Coningsby, a move that was postponed following further investigations.

In October 2013, Lincolnshire County Council*5,6,7 carried out its own feasibility study following a request to investigate possible options for Scampton’s use in the future. The study looked at a range of options including combining civil and military aviation, a combined heritage and RAF base, and an expansion of the site to form a leisure complex. The report concluded that:

  1. The potential for “increased airspace use on a joint military / civilian basis was not feasible given the requirements of RAFAT. This effectively ruled out the option of developing the base as a commercial or leisure aerodrome alongside RAF use“.
  2. Many buildings were not being used and were therefore able to be demolished without any serious issues. Only the hangars were listed and would be more difficult to remove. Whilst there is currently a museum on site, this could be exploited establishing an “aviation focused attraction of national and international importance“.  The cost of such a venture would be in the region of £80m, and it was thought that this would deliver an operating surplus based on “approximately 200,000 visitors per year“.  These figures would make Scampton comparable with the National Space Centre at Leicester, and with a greater visitor rate than that of Lincoln Castle.
  3. It was also suggested the unused space could be turned into leisure activities “themed hotels” for example, and that any such activity would compliment the RAF’s expansion at Scampton should it go ahead. The entire process of this consultation was met with interest by the base commander, and at that time it was thought that Scampton would expand in terms of operational staff.
  4. In conclusion of the study, it was suggested that “The aviation heritage attraction would tell key stories relevant to Lincolnshire and its involvement in defence and aviation. It is likely to attract significant new visitors to the county, generating sufficient revenue to support long-term operational sustainability of the attraction, plus spend in the local economy.” It also suggested that “a major new aviation heritage attraction at RAF Scampton could sit alongside the current scale of military use and would be sufficiently flexible to work with a greater or lesser RAF presence.”

Whilst much of these points include an RAF presence of some sort, it would be flexible in nature until such time as it became self-sustaining. A further option is to develop Scampton retaining its historical features and infrastructure. Much of the married quarters area has already been sold off and is currently in private ownership. These utilise the actual married quarters and has proven quite successful. Further sections of this area are also being sold and developed and so the atmosphere of the site has changed little since its wartime days.

Recently we have seen similar ventures at both RAF Coltishall and RAF West Raynham, where the airfield buildings have been retained (including the hangars, watch office and many associated buildings including the aircraft pens) and the site turned into a working heritage site with small industrial units utilising the workshops and hangars, and private housing using the refurbished personnel homes.

The ‘Grand Slam’ and ‘Tallboy’ bombs at Scampton.

The main argument against closing Scampton is one of cost, defence budgets are being cut and savings have to be made in the estates area. Scampton as it is, is not a viable airfield. However, its historical value is much higher, and any future decision and development needs to take this into account. If we are to retain our aviation heritage then serious consideration needs to be given to Scampton as a future development opportunity, themed hotels, museums of national importance or even a living history museum are all possible. What needs to be considered very carefully, is how that change is brought about. Lack of suitable knowledge or understanding of even small aspects of the site could degrade the overall venture, with important features degrading beyond safe use and poor managerial provision wasting an ideal opportunity in raising public awareness of the site’s true historical value.

Developments at both RAF Coltishall and RAF West Raynham have shown what good planning can do, creating something useful from a former airfield, whilst allowing for the preservation of its unique historic infrastructure.

This is clearly going to be a long and heated discussion, whether Scampton closes or not is only part of the debate, the crux of the matter being the historical value that it holds and what happens to the legacy it carries for all future generations.

RAF Macmerry – The darker side of war.

After visiting both RAF Drem and RAF East Fortune in Trail 42, we travel a few miles south, back to the A1 road where we visit another disused and almost lost RAF airfield. Initially used as a Landing Ground during the First World War, it struggled to become a fully fledged airfield but it did operate a small number of squadrons under RAF control. One of these squadrons had a rather sinister role to play and had Britain been invaded, then its name would no doubt be well-known and common place in history books today.

In Trail 51, we continue on in the south-eastern region of Scotland, not far from the historic city of Edinburgh, where we visit the former airfield RAF Macmerry.

RAF Macmerry (Tranent / Penston).

The former airfield at the small village of Macmerry is today split by the main A1 road, with the flying side of the airfield to the north and the technical and accommodation areas to the south. Sadly the active side has been completely removed and is now agricultural land, but on the technical and accommodation side there are fortunately still a small number of buildings remaining, albeit in private use today.

RAF Macmerry is located some 14 miles east of Edinburgh, its origins extend back to the First World War when it was known as Penston. Used by No. 77 Squadron who were initially based at Edinburgh, it was a Home Defence Landing Ground housing a squadron detachment until the entire unit moved over in April / May 1918, when the Royal Flying Corps became established as the Royal Air Force. No. 77 Sqn were well-known in the area, having detachments based at nearby Turnhouse and also at New Haggerston and Whiteburn. The squadron had been based at Edinburgh since October 1916 after moving there from Thetford in Norfolk, shortly after their inception. During their time at Penston, No. 77 Sqn operated a number of Royal Aircraft Factory types: the BE.2c, BE.2d and BE.2e, the BE.12 and BE.12b along with the D.H. 6 and RE. 8.

Even though No. 77 Sqn moved into Penston full-time, they did retain a detachment at Whiteburn, an arrangement that continued until 13th June 1919, when the squadron (now Royal Air Force) was finally disbanded. No. 77 Squadron would go on to be reformed in 1937, just prior to the outbreak of the Second World War, but they would not return to their roots, and would never again appear at the airfield at Macmerry. After 77 Sqn’s departure from Penston, the RAF had no need for the site, and so the airfield was closed and the site sold off.

The 1920s and 30s then saw a short reprieve for Macmerry as aviation became fashionable. The Edinburgh Flying Club established itself here, and the Scottish Motor Traction (SMT) organisation put forward plans for a new major airport here at Macmerry. Established in 1905, the SMT was an established bus company who also provided an air taxi service flying a De Havilland Fox Moth between 18th July and 31st October 1932. Although these ambitious development plans never came to fruition, Macmerry (referred to as Edinburgh) was used for a short period between 1936 and 1939 for commercial air travel by North Eastern Airways.

After war broke out the RAF were looking to expand their airfields around the UK, and the border regions of Scotland were soon under the spotlight. The Air Ministry identified Macmerry and decided in July 1940, to rename Macmerry as Tranent after the nearby town. However, and even after the official requisition later on, this name change never appeared on any but a handful of official documents and the name Macmerry stuck.

It was around this time too that the Cunliffe-Owen company, a civilian aircraft manufacturing company, began operations at the airfield repairing Lockheed Hudson aircraft. Cunliffe-Owen was set up by the millionaire Sir Hugo Cunliffe-Owen on August 9th 1937 under the name of BOA Ltd, changing it later in 1938, to Cunliffe-Owen Aircraft. Utilising the First World War hangar at Eastleigh in the former county of Wessex, they would be famous for their investigations into the ‘Flying Wing’ project. Cunliffe-Owen also formed a contract with Lockheed Aircraft and began assembling Hudsons along with a large number of other American aircraft imported into the UK for RAF service.*2

On September 2nd 1940, No. 263 Squadron moved into RAF Drem, located about 6 miles north-east of here, and used Macmerry as a satellite airfield, even though the RAF had not officially taken over the site. Regardless of this, the Westland Whirlwinds they were flying, did occasionally use the airfield along with another satellite at Prestwick way off to the west.

In January 1941, Macmerry was officially requisitioned and would come under the control of 13 Group Fighter Command, with the first aircraft arriving very soon after. The Hurricane Mk.Is of 607 (County of Durham) Sqn would stop off here between January 16th and March 2nd 1941, before joining the main squadron also based at RAF Drem. No. 607 Sqn were veterans of the Battle of Britain, and would go on to be the first Squadron to operate the ‘Hurri’ bomber, a Hawker Hurricane fitted with bombs.

As they departed Macmerry, a second unit arrived, No. 614 (County of Glamorgan) Squadron, who were a pre-war squadron and would operate Lysander Mk.II and Mk.IIIs before replacing these with Blenheim IVs in July 1941. After a short spell away at Thruxton, No. 614 Sqn returned to Macmerry for a few days before departing for the final time at the end of August 1942. Flying with the squadron code ‘LJ’, it was these Lysanders that had a rather sinister role to play, and one that was perhaps unique along this coastline of Scotland.

First impressions of Macmerry were not positive for crews, a small hangar and a flying control building were about all that greeted the men. There were no accommodation facilities and airmen were billeted in the homes of local families. Runways at this time were grass (1 x 1,500 yards and 2 x 1,200 yards), whilst the perimeter track was tarmac, a feature that would not change for the duration of the war.

By the summer months accommodation on the airfield was finally available (sufficient for around 1000 personnel of mixed rank and gender) and the whole of No. 614 Squadron moved into Macmerry. Work continued on the remainder of the airfield infrastructure, including six hardstands each holding two-twin engined aircraft in a ‘Blenheim’ style aircraft pen. Otherwise know as type ‘B’ (designed to drawing 7151/41) they had cranked sides and staggered entrances. Each of these had a shelter built into the revetment sufficient to hold 25 men. Eight Blister hangars and a T2 were also added at some point, along with a range of technical buildings.

Working under the control of the Royal Air Force Army Co-operation Command, No. 614 Sqn’s Lysanders were to monitor and patrol Scotland’s east coast, and in the event of an invasion, they were to contaminate the beaches with Gas (possibly Mustard Gas even though this was banned in the 1925 Geneva Protocol) using the vast stocks they had at Macmerry airfield. A lethal substance, it was never thankfully used and was disposed of later on. Much of the information about this has only recently come to light, but according to Operational Record Books*3 gas attacks were something that were rehearsed on many occasions.

Whilst No. 614 Sqn were based here at Macmerry, they performed regular operations with Army units, detachments from Macmerry flying to the Fleet Air Arm airfield at Arbroath where they would carry out photo reconnaissance, simulated dive bombing and these aforementioned gas laying operations. These operations (e.g. ‘FORFAR’, ‘HOPE’ and ‘JOHN’) were carried out in conjunction with various army divisions, with RAF support staff and  equipment (including Bowsers) being taken by road to the detachment airfield. In many cases, the crews and ground staff from Macmerry would be housed in tents supplied by the various army brigades and they would be fed by the Royal Navy, something that the more senior officials within the RAF wanted to stop.

During these exercises, Lysanders would drop messages to ‘message stations’, these message stations would be viable targets for the ‘enemy’ aircraft (bomber sorties being performed by other Lysanders, Spitfires or Miles Masters) and therefore the diligence of those inside was of the utmost importance. Following a review of the first of these operations, this key point was noted in the ORB, in which it was pointed out that  “…only intelligent men should be employed, and the same men, if possible, should do the duty on all occasions.

During August 1941 a detachment of Tomahawk IIA aircraft were to join No. 614 Sqn here at Macmerry. These aircraft were operating with No. 241 Sqn, who were primarily based at RAF Wattisham, but had detachments already at Snailwell, Henlow and Docking and now at Macmerry.

In March 1942 these Tomahawks were replaced by the North American P-51 Mustang Mk.I, an aircraft designed in response to the need for a long-range fighter with outstanding capabilities. Designed by a German born designer, Edgar Schmued, it would become one of, if not the, Second World War’s most successful fighters, especially after it had the Rolls Royce Merlin replace the weaker Allinson. As well as an increase in top speed of around 50 mph, it out performed the Allinson in all other categories including rate of climb and performance at altitude. By May 1942, No. 241 Sqn and their new Mustangs would all depart Macmerry for pastures new at Ayr. However, and not before too long, 241 Sqn would return to this part of the country, spending a short time at RAF Winfield in the border regions working in cooperation with 4th Medium Regiment, Royal Artillery.

It was during May that No. 225 Sqn moved to Thruxton  whilst also having a detachment based here at Macmerry, and once again the Mustang Mk.I would be back in the skies over this small Scottish village. The entire squadron would move onto the airfield at the end of August and would stay until the end of October when they would depart for North Africa taking their Mustangs with them.

By late summer 1942, the accommodation, hangars and major facilities were all now complete and open, the site was now ‘modern’ and homely, engineer’s workshops, allowed for maintenance of the aircraft, and aircraft pens offered protection to both the airmen and aircraft in the case of Luftwaffe attack.

By August 1942, No. 614 squadron were to pull out moving to RAF Odiham where they replaced their aircraft with Blenheim Vs. Their place at Macmerry being taken by No.13 Sqn flying Blenheim IVs. Their stay would, like many of their predecessors, be a short one, another ex Lysander user, they only stayed here for about 10 days before they too moved off to Odiham and onto North Africa.

The November would then see the last operational flying until arrive at Macmerry, and they would be the longest-serving unit to stay here. At the end of November, on the 21st, No. 63 squadron would arrive bringing  with them further Mustang Mk.Is. The main block of the squadron would operate from Macmerry whilst detachments would be placed across the length and breadth of the country at Lossiemouth, Odiham, Dalcross and Acklington. Many of the sorties flown by No. 63 sqn were photographic reconnaissance missions, using F.24 (8″) cameras installed on the port side of the fuselage directly behind the cockpit. Because of the open landscape and close proximity to the coast of the airfield, many sorties flown from here were hampered by high winds and the impending Scottish cold, something that brought discomfort to the may crews who were stationed here at some point.

Originally reformed in the summer of 1942, No. 63 Sqn moved here from Catterick, and stayed until July 1943 when they departed to Turnhouse, leaving only a detachment here at Macmerry. In November, the entire squadron then moved off to Thruxton leaving the airfield at Macmerry behind for good.

Other than a handful of Lysander target tugs and glider trainers, flying wise Macmerry would then fall quiet, the sound of aircraft engines being replaced by the thud of marching boots. During the winter of 1943, Operation ‘Fortitude North‘ was put into place, an operation to fool the Germans into thinking the impending invasion would occur across the North Sea. Macmerry would see a huge influx of army personnel, from No. 2736, No. 2830 and No. 2949 Regiment Squadrons, who would take to the mountains sending out false signals that would be picked up by German intelligence. These groups stayed here for a number of months until moved south for the real  invasion across the English Channel. So successful was the operation that German forces failed to pull vital units away from the Norwegian coastal areas for fear of an impending Allied attack.

RAF Macmerry

Much of what is left is rundown but in use for storing farm machinery.

In the months after the D-day landings, the RAF began to shrink as the need for fighters and heavy bomber began to lessen. The closing stages of the war were near and the fight was well and truly over German soil. The Fleet Air Arm (FAA) however were still expanding, preparing for what was going to be the invasion of Japan. To this end they needed more airfields to train pilots and crews to meet this demand. The Air Ministry considered giving the FAA Macmerry airfield to use, primarily as a repair yard, but, and whilst the offer was accepted, it was never actually put into practice. The FAA also considered stationing No. 770 Sqn FAA here, a Fleet Requirements Unit, whose role was to provide target tugs, simulated attacks on vessels and other gunnery roles. This too however, never actually came to fruition, and whilst the FAA had renamed the airfield H.M.S. Nighthawk II in preparation (Drem being re-designated H.M.S. Nighthawk) they handed Macmerry back to the RAF on March 15th 1946 without ever actually placing a man through its gates. With the war over for the second time, the RAF had no further use for Macmerry, and it was closed down very soon after.

With the airfield abandoned, the Edinburgh Flying Club seized the opportunity to get back into Macmerry, and on August 31st 1946, they reopened the airfield and began to operate from its runways again. They continued to operate here until 1953 when flying finally ceased and Macmerry closed its gates for the last and final time.

After this the site was sold off, the main A1 was eventually built and then later extended into a dual carriageway. As a result of the new road the airfield was split, and the active side developed as farm land. There are suggestions that additional hardstands were provided on the perimeter track on this side, but any sign of these seem to have gone along with the flying side of the airfield. In addition to this, the hangars on the northern side have also been removed and replaced by a rather large grain store.

The accommodation and technical sites were then turned into a small industrial park, the land adjacent to this, being returned to farm land. It is on this land that many of the accommodation buildings have been retained being put to use by the farm to house farm machinery and produce. The WAAF site buildings were demolished but the squash courts and gym both remain today.

The road from the A1 circumnavigates the entire site and it is from this road that the best views can be obtained. From the main A1, the first stop is at the two revetments, which remain sandwiched in between this side road and the main A1. Hidden from view of the A1, they are discernible from the side road and are in remarkably good condition for their age. In a small triangular section of ground, there are several structures here, including the aircraft pens and crew blocks.

The industrial site visible just off to the left of this road is what was the main technical area of the airfield. The modern warehouses and industrial units having replaced the technical buildings that were once thriving RAF workshops.

Continue on and take a left turn. This takes you past the former accommodation sites and the location of the majority of surviving buildings today; long halls with their chimneys which were once the centre of life at Macmerry. Following this road to the left then takes you past the Gym and Squash Courts, passed the accommodation area and back to the A1 and away from the airfield.

The former airfield RAF Macmerry went through a number of changes during its life, and although it has a history dating back to the First World War, it is one of those airfields that never really seemed to establish itself as a front line airfield. The number of squadrons who passed through here also brought a range of aircraft types, giving Macmerry a varied and interesting mix of models. That said, Macmerry had a dark side to it, and had the invasion of Britain come through Scotland’s borders, then Macmerry would no doubt be a name at the forefront of Britain’s history books today.

The Development of Britain’s Airfields (Part 8).

In this, the last of the series looking at the development of Britain’s airfields, we look at the Watch Office, perhaps the most atmospheric of buildings associated with Britain’ wartime airfields. The hub of an airfield control, it was where aircraft were counted out and back, where the battle was monitored and the cries of those who fought in the air war were heard.

Though only a recent addition to airfield architecture, it developed quickly and became one of the technologically advanced offices in the world.

Watch Offices.

The Watch office, Watch Tower or in American terms Control Tower, was the centre piece of any airfield, the place in which all operations were controlled. Even today, the control tower is the one feature that stands high above the rest of the airfield with commanding views across the entire site.

Many of these watch offices remain today, some as fabulous museums, some as private dwellings, but many are sadly derelict or even worse – gone altogether. This that do survive create a haunting and evocative feeling when seen from inside.

Thorpe Abbotts Museum

The beautifully restored Thorpe Abbots Watch Office (design 15683/41).

Unlike hangar development, the watch office appeared quite late in the development of the airfield, only really coming into being as war seemed inevitable. Before this, a rudimentary office was often all that was used, usually attached to the side of the main hangar, and was used to ‘book’ aircraft in and out. But by the mid war period the watch office had become a major structure on the airfield, a standard design (depending upon the airfield use) with two or more floors and often a ‘glass house’ for observation purposes.

For obvious reasons the watch office was built away from other buildings with clear sight over the entire airfield, an important aspect if controllers were to keep watch on the many aircraft that were moving about the airfield space. A vital asset to the airfield it was often targeted by marauding bombers, and in the case of attack, the controllers within would relocate to an emergency battle headquarters, hidden at ground level on a remote part of the airfield, but still with views across the site.

The basic watch office was often adapted rather than demolished and rebuilt, this can and does, cause great confusion as to its design origin. Further more, on some sites, the original was abandoned but not demolished, and a new office built elsewhere on a nearby site, thus giving rise to two offices on the one airfield eg. Matlask and Martlesham Heath

The Watch Office as we know it was first seen on military airfields in 1926 and resembled a small bungalow with bay windows. Those constructed on bomber bases would be slightly smaller than those on fighter bases, a fighter base office having a pilots office attached. The idea behind this was to keep pilots as close to the airfield  control centre so they could quickly be scrambled and report back to the airfield controller on their return. These early design were found on airfields such as Bircham Newton in Norfolk, Hendon and Tangmere and were all built to the same  basic 1926 drawing design only modified to take the extra pilots room.

The standard shape of the World War 2 Watch Office stems back to the mid 1930s, with the introduction of a two-storey building that was square in design. Like similar buildings of its time, it was brick, a building material that was replaced with concrete, in 1936.

By the end of the expansion period, and with the introduction of hard runways, it was realised that the non-dispersed sites gave poor visibility for early watch offices, views across the airfields were not clear and so a quick remedy was called for. The answer lay in two choices, (a) demolish the current buildings  and rebuild it in a better location, or (b) add an extension. In many cases the former was the better idea and this progressed quite quickly, however, where the latter was chosen, remedial work required alteration of the building whilst it remained in use.

A further complication to these designs was the introduction of meteorological sections, which all new buildings erected at the beginning of the war now had. This gave a mix of design styles, enough though there was only a small selection of design drawings from which to work.

These late expansion period and early war designs introduced the idea of ‘viewing platforms’ or parapets, surrounded by safety railings along the front of the building. These deign also had very large glass fronted walls, bright and airy they allowed a lot of light to enter the building but gave cause for concern later on, when it was realised that a bomb blast would cause severed injury to the occupants in an attack. It was also found that during night operations, large windows were more difficult to black out and so smaller windows offered both better protection and greater ease of black out.

As building materials became scare, particularly wood and brick, concrete became the norm. This change also led to drawing changes even though the basic design inside and out, was the same.

In order to appreciate the changes to watch office designs, one needs to consider the different roles that airfields played during the war. Bomber Command airfields would have a differ office to a fighter Command airfield, which in turn, had a different office to a satellite or night-fighter station.

Watch Offices give commanding views across the airfield. (Thorpe Abbots).

The regional control stations where these first offices were being built were certainly getting the better choice at this time, standard fighter and bomber airfields having to use inferior designs that very soon became outdated and inadequate for the needs of the airfield.

During the massive building programme of 1941/42, there was some effort made to standardise all airfield Watch Offices, this resulted in the 1941 design drawing no. 12779/41. This was to be the basic airfield watch office design, with its parapet, six large windows to the front and outside access steps. As older airfields were brought up to Class A Specification, many had these new Watch Offices built to replace the older original ones. Some simply had adaptation of the original. Here the use of the airfield had a bearing on the watch office modification / design, and whilst the basic 12779/41 model was employed, slight variations did exist where the airfield was not a bomber airfield.

Therefore various adaptations of this did follow, examples of which include the slightly smaller 13023/41 (RAF Cottam), those with modified smaller windows 15371/41 (Kimbolton) and 343/43 (Martlesham Heath),  and the smaller Night-Fighter design 15684/41 (Winfield). Being a Night-Fighter station Winfield, had the same basic design but construction methods were totally different. This new design 15684/41, would become standard at all night fighter bases.

All these alternative designs appear outwardly very similar to the original, but differ mainly in window design only, although the physical size of some is different.

RAF Winfield

The Night-Fighter station Watch Office at Winfield (15684/41) is a similar design but smaller, having only four windows in the front.

This design, 343/43, eventually became the most common design for watch offices and appeared on all operational stations and Operation Training Unit airfields after 1943, using a set of six half-size windows across the front.

Tower (2)

The smaller windows of Parham (Framlingham) were half the original design size (12779/41 modified to 343/43).

A further addition was the glass observation room located on the roof of the Watch Office. These were generally only applied to Group control offices, and gave an excellent all round unrestricted view of the entire airfield. Examples that exist today, such as Framlingham above, are replicas but have been built to very high standards.

Former RAF Martlesham Heath

Martlesham Heath is a similar design to Framlingham (modified to 343/43) – Note the runway heading board on the roof.

At the end of the war some airfields such as Sculthorpe and West Raynham had their Watch Offices modified as they changed roles to Very Heavy Bomber Stations. This new design 294/45, utilised the former building having an extra floor added and then the octagonal ‘glass house’ or Visual Control Room with slanted glass to reduce glare.

Control Tower

Sculthorpe’s modified tower gives 360 degree views over the airfield. A three-story block it utilises the former World War 2 Watch Office.

The Watch Office has been the hub of airfield command and control since the mid 1930s, it has developed from the humble shed to a multi-functional technologically advanced building dominating the skyline of the airfield today. Sadly though, many are now gone, and of those that are left only a few remain in good condition or open to the public.

Summary

The war-time airfield incorporated numerous building designs and shapes, certainly far too many to cover here, the wide variety of technical buildings, synthetic trainers, parachute stores, headquarters and general stores, all changing as the war progressed.  The design and materials used in these structures was as varied as the designs themselves. But as the RAF grew so too did the airfields they used. The runways, the hangars, the technical buildings and accommodation sites have all grown alongside. Sadly many of these buildings have now vanished, but the process and speed at which they developed has been unprecedented. From humble grass strips with wooden shacks to enormous conurbations with numerous buildings, they have become iconic symbols representing decades of both aviation history and human sacrifice.

The Development of Britain’s Airfields (Part 7).

Whilst the runway’s remains one of the biggest features of an airfield, perhaps one of the most discussed and certainly visible is the hangar. Large sheds used to maintain aircraft, many still dominate the skyline today, used by farmers and industrial companies, they are massive buildings, but yet many remain classed as temporary or even transportable!

The development of these huge buildings is another that lasted many years, and whilst similar in layout and design, they are as complicated and as varied as any other building found on Britain’s airfields.

Hangars and Aircraft Sheds.

The topic of aircraft hangars is well versed in a large number of books and internet references. They, like the runways, can explain much about the history and use of an airfield, being the largest single building on any airfield site. Distinguishing features between hangar types is often difficult to see, many now re-clad or updated with modern features, doors or materials, even the differences between some designs is so small, without technical drawings or measurements, ascertaining the type can be all but impossible.

Hangars (or aircraft sheds as they were initially called) have been fairly constant in design, however, different services used different types, Admiralty seaplane sheds for example, were primarily side opening, whereas RAF hangars were generally front opening. Design and construction was undertaken by numerous companies (Herbertson & Co. Ltd., Nortons Ltd., Teeside Bridge and Engineering Co. Ltd., and Sir William Arrol & Co.) and even Handley Page Aircraft Co. and Boulton & Paul dabbled with the idea. With so many forms being used, it is a topic both detailed and extremely wide.

This is not therefore, intended to describe each and every hangar ever built (Second World War Air Ministry designs alone covered more than 56 types!), but more a general realisation of the huge development they undertook during this expansion and wartime period on RAF / USAAF airfields. Figures quoted here are generally rounded.

In order to understand the changes in aircraft hangars we need to briefly look at those of the First World War, where aircraft were stored in ‘sheds’, often made from canvas covering a wooden frame, or as a more permanent construction, completely wooden sheds with sliding doors. Later on these were built using metal (iron in particular) and were designed to be permanent, capable of housing several aircraft at a time.

The First World War hangars were varied and often crude, some little more than glorified tents, but through development famous names such as the Bessonneau and Hervieu were created toward the end of the war. Hangars became so large that specialist units had to be created solely to transport, erect and maintain them, and their use became more widespread.

The most common hangar of this period, the Bessonneau, was the first standard transportable hangar used on Royal Air Force airfields. Modern forms of it are still in use today, using different materials, they are quick to erect and offer reasonable protection from the weather outside.

The Bessonneau was a wooden frame structure covered in canvas. It was a simplistic design, able to be erected in as little as two days by a group of 20 skilled men. Heavy canvas doors open at one end allowing aircraft to be moved in and out with relative ease. The problem with these hangars was that the canvas was prone to freezing in winter and therefore becoming difficult to use.

There were two models of the Bessonneau built, differing only in their length – either 79 feet or 118 feet – but both were 65 feet wide.

The interwar and early war years were perhaps understandably,  the years in which the greatest hangar development occurred. The Air Ministry – the body overseeing the works – decided upon a system of ‘structure type’ using names and designations such as, Type ‘A’, ‘B’, ‘C’, Bellman, ‘T2’, etc., and just like the expansion period schemes, they progressed through this system as new developments came about.

The first type was the Type ‘A’, a permanent design, originating in 1924, it was used well into the 1930s when it was gradually replaced during the expansion period. Some examples did last well into the war and even beyond, for example, North Weald, one of the first airfields to be allocated a Type ‘A’, still uses one today.

Type A Hangar

Type A Hangar at North Weald. One of the first stations to have these types of Hangar, it has workshops attached to the Hangar side.

The Type ‘A’ is probably the first to represent the modern hangar, doors at both ends in leaves of four running on rails. Workshops are attached to the hangar side, something that was discontinued as Britain entered the war. Walls were reinforced with concrete to protect from bomb splinters, and they were built 249 feet long and 122 feet wide.

During the late 1920s, the Air Ministry published requirements for new heavy bombers, and these would require new hangars in which to maintain them. In response, the Ministry then updated the Type ‘A’ hangar to the Type ‘B’. In essence a larger version of the Type ‘A’, (160 ft span and 273 ft in length) the ‘B’ was named the ‘Goliath‘ with only three being built (each being a different length). One of these was at RAF Martlesham Heath and is still used today on what is now the industrial park. Like the Type ‘A’, the roof of the ‘B’ is possibly its most discernible feature, a series of trusses along its length crossing laterally over the roof.

With expansion period demands increasing, further developments were needed, and it was envisaged that an increasing bomber size would be needed if substantial bomb loads were to be delivered deep into the continent. The current size of hangar was now considered too restrictive and so a new buildings would be needed. The requirements of the Air Ministry was for a hangar with a span of 150 feet and length of 300 feet. With these in place, new aircraft specifications could be issued.

The Type ‘C’, (designed in 1934) as it was designated, would become the dominant building on any airfield and therefore visible from quite a distance. As airfield designs were subject to scrutiny by the Society for the Preservation of Rural England, local objections were taken into account during the design process. To appease any  objections, the steel frame was covered with local brick or stone, keeping it inline with other buildings not only on the airfield, but houses and buildings erected locally.

Most airfields during the expansion period were built with these hangars on site, and naturally went through a series of developments and improvements. This means, that there are many different forms of the Type ‘C’: gabled roof, hipped rafter and reinforced concrete. Another modified version of the ‘C’ appeared in 1938 and was designated the ‘C1’ (or ‘Protected’), this was an austerity measure development, reducing the amount of material used by lowering the roof height by 5 feet – internal metal work was also left partially exposed. Both the ‘C’ and ‘C1’, continued to be built with offices, workshops and aircrew accommodation attached to the hangar side, the idea being that it was more efficient to do so for the repair of the aircraft inside. As these were larger in width and length than their predecessors, they would have six leaf doors also sliding on top and bottom rails.

1936 saw a dramatic change in hangar design, with two new requirements being issued by the Air Ministry. Firstly, storage space was now running out and so new facilities were required. These Aircraft Storage Unit Stations (ASU) would need their own hangar type, and so a requirement for these was put forward. Also at this time, the Ministry put out a demand for transportable hangars, these would replace the ageing Bessonneaus of the First World War. The response to these demands were three storage hangars and two temporary hangars.

Storage Hangars.

The Type ‘D’, ‘E’ and ‘L’ Hangars, were a development used specifically by the ASU stations, and they were not generally built on front line operational airfields. They were virtually identical in size to the Type ‘C’, but each type was marginally bigger in span 150 ft, 160 ft and 167 ft than the previous model, and all were the same length at 300 feet. The three types were different from previous hangars in that they had curved roofs, allowing the ‘E’ and ‘L’ to be covered with soil for protection and camouflage (the ‘D’ had straight side walls and therefore could not be covered). ASUs were built to assemble and disassemble aircraft for shipment to operational airfields in Britain or overseas. Aircraft were stored, in varying degrees of assembly within these units, and heavy hoists were often used to store aircraft ‘tail up’. However, with the outbreak of war, aircraft storage was thought better dispersed around the airfield and not concentrated in one space, so this method of storing aircraft was abandoned. Many of these hangars still remain today, used by small industrial units or for farm storage.

The next two types, the ‘J’ and ‘K’, were virtually identical in design, again with curved roofs, they were used for storage of aircraft. The ‘J’ can be found on many operational airfields, built in conjunction with other main hangars (Waterbeach is a very good example of this combination), whilst the ‘K’ was built on ASU stations. The design came in as a result of Expansion Scheme M, and was as a result of the call for 2,550 front line aircraft by March 1942.

The main difference between the two, (other than their location) was in the roof structure, the ‘K’ having lifting tackle rails along its width, while the ‘J’ were along its length. The ‘K’, being used for storage of aircraft, didn’t have any windows, where as the ‘J’ did as offices and workshops were in use constantly. Like previous hangars, the ‘J’ and ‘K’ both had a span of 150 ft and a length of 300 ft.

Transportable hangars.

The 1936 transportable hangar requirement, asked for a hangar that could be easily erected and didn’t require a permanent base. It also asked for doors at both ends and needed to be simplistic in design, with parts being interchangeable. These hangers also saw the separating of the office/workshop facilities previously built onto the side of the hangars, these now being located in buildings in the technical and administrative areas. After considering numerous designs, two were chosen and ultimately built.

The first of these, and the primary choice, was the Bellman. Designed by an engineer within the Works Directorate, N.S. Bellman, they were smaller than previous hangars (88ft span and 175 ft on RAF bases) and could be built in under 500 hours by a dozen men. So successful, were they, that over 400 were built between 1938 and 1940 across a wide range of airfield types. Some of these examples even appeared in Russia.

The second design, was the Callender (later Callender-Hamilton with modifications) Hangar, designed by the bridge design company Callender Cable and Construction. These had a span of 90 clear feet, with a length of 185 ft, and were used on both RAF and RNAS airfields. There were only eight of these built before the outbreak of war, examples of which appear at East Fortune, further examples with lower roof clearances (17 ft) being purchased after 1940. The Callender-Hamilton are best recognised by their lattice-work on the top door rails.

As the war approached, 1939 – 1940 saw a transition period between ‘permanent’ and ‘temporary’ buildings, although many of these temporary buildings still stand today! Because of this change, many airfields had various hangars built, something that often gives a mix of hangar designs on one airfield which can cause confusion as to its age and origin. However, from this point on, all wartime hangars were designed as temporary hangars, designed with short lives and easily assembled / disassembled.

By 1940, the Bellman was considered too small for the RAF’s requirements and a new design was going to be needed. An agreement between the Air Ministry and Teeside Bridge & Engineering resulted in the ‘T’ series of hangars, perhaps the most well-known of the hangar designs.

The ‘T’ series covers a wide range of (temporary or transportable) hangars, each slightly different to the previous, but designed as three main types; T1 (90 ft span), T2 (113 ft) and T3 (66 ft). The length of each hangar varied depending upon local requirements and the number of additional bays added as needed. The design number e.g T2 (26) indicated the number of bays (26) and hence the length.

The ‘T’ range were a diverse and complicated range, the ‘T2’ being sub split into 5 variants (T2, T2 Heavy Duty, TFB (flying Boat), TFBHD (flying boat heavy-duty) and T2MCS (marine craft shed), so the identification of each being difficult without measuring equipment.

RAF Wratting Common

On first inspection the ‘T2’ and Bellman look virtually identical, both lightweight, steel lattice frames with metal side panels. The main distinctions are that the Bellman doors are flush with the top of the side panelling whereas the ‘T2’ has an extra level of panelling and so are not flush. The other difference is the lattice frame inside the roof, the ‘T2’ has only diagonal braces whereas the Bellman has vertical braces in addition to the diagonals. Both hangars have six leaf doors on sliding rails supported both top and bottom, allowing full width access.

A final addition to the ‘T2’ were the Ministry of Aircraft Production Hangars the Type ‘A’ (A1 & A2) and Type ‘B’ (B1 & B2) built in the mid war years 1942-43 and funded by the Ministry of Aircraft Production. These hangars, not to be confused with the type ‘A’ and ‘B’ of the 1920s, were designed specifically for the repair of damaged aircraft especially operational aircraft on their own airfield. They were also erected at ASUs, and Satellite Landing Grounds (SLG).

RAF Wratting Common

A B1 at RAF Wratting Common an RAF bomber station.

The ‘B1’ and ‘B2’ were built specifically at Bomber Command airfields for the repair of damaged bombers thus eliminating the need to transport them long distances to specialist repair depots. Designed by T. Bedford Consulting Engineers they were eventually found on virtually all Bomber Command airfields by the end of the war and were manned by civilian repair organisations. Examples of both the ‘T2’ and ‘B1’ can be found in use at Wratting Common.

‘A1’ and ‘A2’ hangars on the other hand, whilst similar in design – metal cladding on metal frames – were slightly smaller and found only on aircraft factory airfields. Thus again there are virtually two identical hangars designated primarily by their location!

The last hangar to be commonly found on RAF / USAAF airfields were the blister hangar. A hangar of a temporary nature that usually used a curved metal frame covered in metal sheeting. The Blister hangar was the brainchild of architects and consulting engineers Norman & Dawbarn and William C. Inman of Miskins & Sons, and was designed to accommodate small span aircraft ideally fighters dispersed around the perimeter of airfields. Maintenance or storage could easily be carried in these hangars, and they could easily and quickly be erected, no base or foundations being required before hand.

These types of hangar came in three designs, the standard blister, (timber construction), over type (light welded steel) and Extra Over (also light welded steel), and ranged in span from 45 – 70 feet, A further type built was that of Double extra Over and Dorman Long, a separate design similar in shape but securely bolted to foundations. Many of these hangars have now gone, the majority being dismantled and sold off, only to be erected elsewhere on farmland well away from their original location. The father of a friend of mine, was employed in this very role, one day finding a Spitfire inside a blister hangar which nobody claimed to own!

By the end of the war, in excess of 900 ‘T2’ hangars were erected on British airfields including those built abroad. In 2004 it was thought there were about 100*7 left surviving on MOD property in Britain. A number have also survived on farmland used to store foodstuffs or machinery, or industrial sites. The ‘T2’ remained the main hangar in use by both the RAF and USAAF during the war, appearing on all Class ‘A’ airfields, occasionally with other models also being present. A number of other older models also continue to serve even to this day. Considering many of these were built as temporary buildings, they have survived remarkably well and are testament to the engineering design of the pre and early war years.

This is by no means an exhaustive list of those hangars that were built during the period 1918 – 1945 (other examples include the: Aeroplane Twin Shed; RFC Sheds; Seaplane Sheds; General Service Sheds; Plane Stores; Running Sheds; Lamella (a German idea built in Britain); Hinaldi; Main Hangars; Lamson Hangars; Fromson Hangars; Robins Hangars; Butler (a US design); Merton; ‘S’ type Hangars (RNAS); Pentad Hangar and Boulton & Paul Hangars and of course post war examples such as the Gaydon), but hopefully it has shone a glimmer of light on these remarkable structures that often dominated the skyline and that remain the centrepiece of many a disused airfield today.

In the next section we shall look at that other main iconic building in airfield design, the watch office.

The Development of Britain’s Airfields (Part 6).

After considering the architecture of Britain’s airfields in Part 5, we turn to the hard surfaces, primarily the runways. Developed out of necessity, they created a steep learning curve for those involved in their construction. Many problems were found, many materials were tried, but ultimately they were built and even after their removal for hardcore, many have left scars in the tissue of the earth that remind us of their once massive presence.

Runways, Perimeter Tracks and Hardstands

In the pre-war years, the development of hard runways and large airfields was a new phenomena, hard surfaces being a new aspect still very much a topic of considerable controversy. In the First World War, water logging and mud was an issue even for the small biplanes that filled the skies over Britain and  France. To overcome this, ash was spread over landing surfaces and to some degree successfully, but even though many local remedies were tried, it wouldn’t be taken seriously until the Second World War loomed.

Glatton (Conington) second runway markings

Runways like this one at Glatton (Conington) remain in good condition and used by the local flying club.

At this point the typical airfield layout included up to four grass runways, one of 1,300 x 400 yards and three of 1,000 x 200 yards, many were even smaller. Bomber and Fighter Command, realising that not only would the new era of aircraft call for longer, hard runways on its airfields, but the need to maintain year round activity was essential if Britain was to defeat the Luftwaffe.

Both Fighter and Bomber Command pushed the Government to allow these to be developed, on the one hand Sir Hugh Dowding, fighting the corner for Fighter Command, pressed home the need for hard surfaces on his fighter airfields, whilst Sir Arthur Harris on the other, pushed for hard surfaces on his bomber airfields.

The entire process was lengthy and complex, and lacked in-depth, professional knowledge. The first hard ‘pavements’ later runways and taxi ways, being constructed based on road building techniques and knowledge. So before any firm decisions could be made, trials would need to be carried out to determine not only whether or not they were indeed needed, but if so, how they should be best constructed.

Initial steps in runway construction was started as early as 1937, where ‘flexible’ runways were constructed comprising layers of brick or stone covered with two further layers of tarmac and a coat of asphalt to seal the structure in. Concrete pavements, which proved to be much stronger were either 150 mm or 200 mm thick slabs laid directly onto the ground after the topsoil had been removed by heavy machinery. As would be expected, these early designs failed quite quickly under the heavy loads of the fighters and bombers that were coming into service. Rapid repairs were carried by adding a further layer of tarmac (6.5cm) and another layer (2cm) of sealant.

These early flexible constructions continued to fail whereas the concrete designs stood up to much more wear and tear and proved longer lasting. However, time was short and the learning curve would be steep.

The test to determine these needs was to take a Whitley bomber, laden to equal its full operational weight, and taxi it across a grassed surface.  A rather primitive assessment, it was intended to ascertain the effects of the aircraft on the ground beneath. Trials were first carried out at Farnborough and then Odiham, and these were generally successful, the Whitley only bogging down on recently disturbed soils. Further trials were then carried out at RAF Stradishall in March 1938, and the results were a little more mixed. Whilst no take offs or landings took place during these trials, the general agreement was that more powerful bombers would have no problems using grassed surfaces, as long as the ground was properly prepared and well maintained. All well and good when the soils were dry and well-drained.

By April 1939, the Air Ministry conceded, and agreed to lay runways at a small number of fighter and bomber airfields, of which Kenley, Biggin Hill, Debden and Stradishall were identified.  Whilst construction was slow, only two fighters airfields being completed by the outbreak of war, progress was finally being made.

These initial runways were only 800 yards long and 50 yards wide, but were extended later that year to 1,000 yards long, as aircraft were repeatedly running off the ends on to the grassed areas. Over the years Stradishall in particular, would be further developed, its longest runway eventually extending to 2,000 yards.

RAF Charterhall

During the early war years, the demand for airfields grew. By early 1940 the requirement was for three runways as close as possible at 60o to each other, and of a minimum length of 1,000 yards with room for extension up to 1,400 yards. This then became the norm by late 1940 especially at bomber airfields, with the main runway being 1,400 yards and subsidiaries at 1,100 yards. A month later, this increased by another 200 yards with a requirement to be able to extend to 2,000 and 1,400 yards respectively.

However, these short piecemeal responses were not sufficient and it was both a continual problem and a thorn in the side for the Air Ministry. Sir Arthur Harris, in raising his concerns for airfields belonging to Bomber Command, also pushed the need to develop good, long and reliable surfaces. He voiced his frustration in a vehement letter*6 to Lord Beaverbrook in 1941, In which he states:

“For twenty years everybody on the stations and the squadrons has been screaming for runways without avail.”

and he continues stressing the need for hard surfaces particularly in winter as:

“Through not having runways our effort will be seriously detracted from in normal winter conditions and reduced very probably to zero in abnormal winter conditions.”

He then goes on to state that Britain’s views were ‘blinkered’ saying that:

“Every other nation throughout the world has long been convinced of the necessity for runways…”

By the summer of 1941, the length of runways had again increased, all stations would now have a main runway of 2,000 yards and two subsidiaries of 1,400 yards and where this was not possible, then a minimum of 1,600 and 1,100 yards (fighter and night fighter stations being shorter at 1,300 and 1,400 yards respectively).

The harsh winters were less than ideal for laying concrete (by far the best material for the job) but any delay could mean the difference between success and failure. Elaborate testing was therefore passed over, materials were laid and experience led the way. This method of trail and error, led to many instances of runways having to be dug up and relaid, this in itself led to problems as aircraft, men and machinery had to then be moved and housed elsewhere. The American Eighth Air Force suffered greatly with these problem, fully laden bombers repeatedly breaking through the surface or falling off the edges as it gave way.

Another consideration was that of training and satellite airfields. As the need for new pilots increased, the training of new recruits intensified. The harsh winters were causing major headaches for these airfields as mud, stones and other winter debris was causing continuous problems for flying. With both man power and materials being in short supply, suitable alternatives were sought.  A number of solutions were offered all very similar in their design and material.

The answer it seemed lay in steel matting – of which twelve different types were used – the more common being : Sommerfeld Track, Pierced Steel Planking (PSP – also called Marston Mat), or Square Mesh Track (SMT).

Sommerfeld track was a steel mat designed by Austrian Kurt Sommerfeld. The tracking was adapted from a First World War idea, and was a steel mat that when arrived, was rolled up in rolls 3.25 m (10 ft 8 in) wide by 23 m (75 ft 6 in) long. It was so well designed that a full track could be laid, by an unskilled force, in a matter of hours. Each section could be replaced easily if damaged, and the entire track could be lifted and transported by lorry, aeroplane or boat to another location and then reused.

Sommerfeld track (along with these other track types) were not only used commonly on training and satellite airfields, but also on Advanced and Forward Landing Grounds in Kent and later France after the Allied invasion of Normandy. In the build up to D-Day, 24 Advanced Landing Grounds in southern England were created using this form of Steel Matting,

Tracking had to be robust, it had to be able to withstand heavy landings and be non-conspicuous from the air. Sommerfeld track met both of these, and other stringent criteria very well, although it wasn’t without its problems. Crews often complained of a build up of mud after heavy rain, and concerns over both tyre and undercarriage damage were also extensively voiced; several records reporting tail wheels being ripped off after catching in the track lattice.

Because of the poor state and short length of runways, bombers were still regularly running off the ends, especially at night, or being unable to fly because the surfaces were poor or even unusable. A number of ideas were tested out to alleviate the problem, one such idea led to twenty sites testing arrester hook facilities. Several heavy bombers: Halifax, Manchester, Stirlings  and later the Lancaster,  were all modified to undertake these trials, with Woodhall Spa becoming the first airfield to have the full complement of six arrester sets.

The idea was met with scepticism, but trials went ahead and in January 1942, a list of priority airfields was sent out to the Headquarters of No. 1,3,4, and 5 Groups RAF detailing those twenty sites selected for the equipment. At the top of the list was RAF Woodhall Spa in Lincolnshire, followed by Bottesford, Swinderby, Ossington, Syerston, Middleton St. George, Linton, and ending with Waterbeach and Stradishall. By late 1942 Woodhall Spa was ready and in October, five landings were made by an Avro Manchester.  A month later the decision was made to install units at all major operational airfields, but this never came to fruition and the idea was soon mothballed. By 1943, it had been forgotten about and the 120 or so units built were scrapped (many being left buried where they were laid).

It was finally during early 1942 that a standard design airfield would be put in place. Known as the Class ‘A’, it would be the standard to which all new airfields and updated older sites would be made.

A Class A airfield would be designed around three hard concrete runways, shaped like an ‘A’ with each runway at 60o  to each other where possible. The main runway would be aligned with the prevailing wind again were possible to allow aircraft to take off/land into the wind as often as possible (north-east, south-west). In several cases, due to land features and local restrictions, this was not always possible, and so many permutations of design were seen as a result.

Rapidly becoming the largest part of the airfield layout, the runways and other paved areas – perimeters tracks, aprons and hardstands – were now given high priority. The standard now called for a main runway of 2,000 yards with two subsidiaries of 1,400 yards. Each of these would be 50 yards wide whilst the connecting perimeter tracks would be 50 feet wide. Along side these runways would be an emergency landing strip, a grassed area given a landing surface of 400 and  200 yards respectively.

Dues to the high numbers of bombers returning badly damaged and unable to make safe and proper landings, a small number of emergency strips were created by extending the main runways to 4,000 yards long and 400 yards wide. One such airfield was RAF Manston in Kent. Being on of the closest airfields to the continent, it was often the first place a stricken aircraft, especially a bomber, would seek out.

Whilst the general layout of airfields did not change for the remainder of the war, some further runways were extended to 3,000 yards, one such example being RAF Sculthorpe in Norfolk which was prepared to take the heavy B29 ‘Superfortress’ and post war, the B-36 ‘Peacemaker’.

A further point worth mentioning here is that of dispersals, not required pre-war, they were also an aspect of airfield architecture that were born out of the Second World War. In the inter-war years, aircraft were housed either on a central pan (apron or ramp) or within hangars. These collections of aircraft were easy targets and even a small amount of munitions could cause huge damage. In 1939 the need for dispersals was therefore recognised and so to address the issue, hedges were removed and tracks created that took aircraft away from the main runway but kept them within easy reach of the airfield site. The initial design was that of the ‘frying pan’ a 150 ft circle connected to the perimeter track by a small concrete track.

However, by 1942, it was found that aircraft were clogging up these tracks, some even ‘falling off’ the concrete onto soft soil and so blocking following aircraft in their tracks. The answer was the ‘spectacle’ or ‘loop’ hardstand, so-called by their oval shape, generally in pairs, that allow aircraft in and out without the need to turn or block access tracks. From 1942 onward, this model became the standard hardstand for all Class A airfields, and the aim was to have 50 such hardstands placed strategically around the perimeter, with 25 at satellite airfields. As the threat of attack diminished toward the end of the war, ‘finger’ or ‘star’ dispersals began to appear, much less effective than the predecessors, they were however cheaper and easier to construct.

RAF Milfield

Unusual as many training airfields didn’t have aircraft pans, RAF Millfield, in the borders, had several

In addition to hardstands, pens were built on fighter stations. The first, an experimental pit, was dug at Feltwell, whilst overly expensive and obtrusive, it did lead the way to aircraft pens later on, pens that were developed as either type ‘B’ or ‘E’  on these fighter airfields. The main difference here is that the early type ‘B’ had cranked side walls whereas the ‘E’ had walls that were straight. The former requiring more space, was later phased out in favour of the ‘E’, named so by its shape, using side and back walls to protect the fighter or small bomber located within.

Examples of these pens were located at Matlaske (type ‘B’ – built to design 7151/41) and Macmerry in Scotland, whilst the type ‘E’ were found on airfields especially those around London that included Biggin HiIl, Kenley and North Weald.

Kingscliffe airfield

These pens were designed to specific dimensions and were designed as either a ‘Hurricane’ or ‘Blenheim’ to accommodate either a single engined or twin-engined aircraft. Within the back wall of these pens was a shelter for up to 25 personnel, and in some cases, they had Stanton Shelters built-in to the structures. Some, for example, at Kings Cliffe in Northampton, remain with rifle slits for additional protection from ground forces.

King's Cliffe airfield

Whilst the majority of these shelters were manufactured using banks of soil, sandbags, brick or concrete, there was a least one example at RAF Drem, in Scotland which used logs cut to size and shape and built in the style of a Scandinavian house. It is these various designs of aircraft pen that paved the way to modern hardened aircraft shelters (HAS) seen on military airfields today.

From the early days of grass runways to the massive lengths of concrete that were created up to and after the mid 1940s, runways and hardstands have become a defining factor in airfield design. The sole purpose of an airfield – to get aircraft off the ground as quickly as possible, get them to their target and them get them home again – led to the development of both runway lengths and construction materials, much of which has paved the way for modern airfields today. These early leaps into runway designs have enabled larger and heavier aircraft to make those important journeys that we very much take for granted in this the modern world of air travel and general aviation.

In the next section we look at one of the buildings most associated with the airfield. An early form of aircraft storage, its role changed as it was soon realised that aircraft needed to be dispersed and not grouped together on large aprons as they were in the prewar era. Aesthetics and neatly lined up aircraft were no longer an important factor in front line flying, but safety and the ability to repair aircraft quickly and efficiently were. Here we introduce the hangar, a huge building often of a temporary or transportable nature, that became one of the more longer lasting structures of airfield architecture.

*6 Letter from Arthur Harris to Lord Beaverbrook, February 1941 – AIR 19/492 – National Archives

The Development of Britain’s Airfields (Part 5).

Once the airfield had been built (Part 4), it was occupied by ground and later air forces, and became operational. However, the process by which it was developed, was not haphazard, nor was the architecture of its buildings. Designed to meet specific needs, the airfields of Britain were built using local knowledge, materials and in many cases architectural design.

Airfield Architecture

Any of these airfield developments had to be in line with guidelines laid down by both the Royal Fine Arts Commission and the Society for the Preservation of Rural England, hardly what you’d want in such difficult times! These restrictions however, would initiate a building design that would initially be both functional and aesthetically pleasing, with standard designs varying only through local conditions (suppliers of local brick for example). In the early schemes a ‘Georgian’ style of architecture was chosen for all permanent brick buildings, distinguished by their pillars and ornate archways, often seen on the entrances to Officers Quarters.

RAF Stradishall

The Officers Quarters at RAF Stradishall were reflective of the types built during war-time under Scheme A

Officer's Quarters now called 'The Gibson Building'.

Standard designs allowed for replication across numerous airfields, the idea being an officer could lift his room from one site and drop it directly on another. RAF West Malling, (built under Scheme M), reflecting this with Stradishall, (Scheme A), above.

All buildings were constructed from brick with roofing tiles chosen accordingly for the local conditions. As the schemes progressed and brick became scarce, concrete was used as a cheap and strong substitute, certainly for technical buildings but less so for administration and domestic structures.

As each scheme was replaced, any previous buildings would have remained (some modified to the new standard), thus some sites will have had a range of building types, often leading to confusion and a mix of architectural styles. The accommodation areas themselves changed too. In the early war years and as the awareness of air attack increased, accommodation was built away from the main airfield site and outside of the airfield perimeter. Classed as either ‘dispersed’ or ‘non-dispersed’, they were identified by the location of these domestic sites, where ‘non-dispersed’ were within the perimeter, and dispersed were beyond the main perimeter area of the airfield.

Barrack block Type Q (RAF Upwood)

The changing face of Barrack Blocks. A Type Q Barrack block at RAF Upwood, built to design 444/36, to accommodate 3 NCOs and 68 aircraftsmen. Compare this flat-roofed, expansion period building to the later Nissen hut.

In these early stages little consideration was given to air attack, and so ‘non-dispersed’ sites were still being constructed at the beginning of the war. The benefit of these sites being that all personnel were in close proximity, general accommodation buildings often being built around the parade ground, and with all the amenities under one roof. These sites also saw the segregation between officers, sergeants and other ranks along with separate married (many with servants quarters) and single quarters. However, with the outbreak of war and as a result of austerity measures, the building of separate married quarters ceased. Examples of these early non-dispersed designs include: StradishallMarham, Tern Hill, Waddington and Feltwell.

RAF Debden

RAF Debden, a non-dispersed site where accommodation and administrative areas were collectively close to the main airfield site within the outer perimeter (IWM17560).

The layout of these barrack blocks, took on the familiar ‘H’ shape, a design that replaced the initial ‘T’ shape of the post First World War and inter-war years. The ‘H’ Block became the standard design and gave a distinct shape to accommodation blocks on these prewar non dispersed airfields.

As the awareness of the dangers of non-dispersed designs became all too apparent, dispersed sites became the norm, where domestic areas were located a good distance from the main airfield site. Dispersed accommodation could have many sites, depending largely upon the nature of the airfield (Bomber, Fighter etc), when it  was built and whether it was operated by the RAF or USAAF. In these later dispersed schemes, domestic sites became more temporary in nature, whilst some remained as brick, many were built as prefabricated units often as Nissen or Quonset style huts, often due in part to the shortage of brick for building and the speed at which they could be erected.

With the changes in dispersing accommodation blocks away from the main airfield, safety increased but both administrative and operational effectiveness noticeably dropped. It was going to be a fine balance between keeping a safe distance and achieving maximum effectiveness.

Andrewsfield Accommodation site

Depending upon local topography, these domestic areas could be situated as much as two miles from the airfield site, wooded areas being utilised where possible to hide the location of huts; blocks were randomised in their position to break up the appearance of housing, and pathways weaved their way round the sites to reduce their visual impact. In most later airfields, a public road would separate the technical and accommodation sites, with as many as thirteen or fourteen sites becoming common place.

The separation of WAAFs from RAF communal quarters also ceased, men and women now allowed to mix rather than having the separate sites for each. As a result many post 1942 sites had fewer dispersed sites then those of pre 1942.

The design of the technical areas also took on a new look. The prewar practice of squadrons offices being attached to the hangar was dropped, these also being placed away from the main technical site, dispersals for ground crew or waiting pilots were spread about the perimeter so airmen could be closer to the aircraft but far away enough to be safe in the case of attack. This led to a number of buildings appearing on the outer reaches of the airfield, along perimeter tracks and near to hardstands, often these were brick, small and square, others more temporary.

Further changes occurred with the reduction in available materials. These changes have given rise to a wide variation in building design, again many airfields having a variety of buildings using different materials.

Initially, buildings built of brick were strong and commonplace, but as this became both scarce and time-consuming to build, alternative forms were found. Timber followed on, but it too proved to be time-consuming to manufacture, and by 1940 acutely rare also.

A range of materials were looked into, using a mix of timber and concrete, plasterboard and concrete, but they were all below the Air Ministry standard. Even so, many were accepted as design alternatives and used in temporary building construction.

1940 saw the return of the 1916 designed Nissen hut, a curved hut that bolted together in widths of 16, 24 or 30 feet. A cold but effective hut it was commonplace on many airfields as both accommodation huts and technical huts, many being sold post war, and ending up in farmer’s fields many miles from the nearest airfield. With the arrival of the USAAF in 1942-3, they brought with them the Quonset hut, bigger in design than the Nissen, they are mainly distinguishable by their curvatures, the Quonset being semi-circular to the ground whilst the Nissen gave a 210o curvature. This extra curvature gave greater use of ground space, but lacked in overall space compared to it US counterpart.

RAF Matching Green

Nissen Hut on Acc. Site

The Nissen hut had a larger curvature giving greater ground space – RAF Fersfield.

Even this material became in short supply, metal being scare and urgently required for the building of military hardware. In 1942 the Ministry of Works took over control of hut design, manufacture and supply, and various new designs were brought into play. Asbestos became popular again, with the US being able to supply large quantities of the material. Uni-Seco Ltd, Turners Asbestos and Universal Handcraft being examples introduced at this time.

The final design to be used, was that of the Orlit, a reinforced concrete panel and post design that slots together to form the walls and roof. Also know as the British Concrete Federation (BCF) design they were quick to erect and lasted from many years. This type of design was used for emergency housing in the post war period and has since proven to be degrading to the point that some of these properties have been condemned.

Thus the architecture of airfield buildings took on many guises, from permanent brick designs, through timber, timber and plasterboard mixes, various metal design, asbestos and finally concrete, all of which gave a change in shape and design examples of which could appear on many airfields. The most common surviving examples today being the Nissen hut.

In the next section we shall look at the runway, the very heart of the airfield and often the defining factor in its designation.

Warning over Airfield Closures.

A recent report on the BBC has highlighted a number of military airfields that are set to close over the next six years, with the potential loss of thousands of jobs. However, the threat is much wider than that, and an all-party group have now highlighted the issue, putting pressure on the Government to take action before the situation becomes extremely serious.

In the report, the BBC say that the all-party group on general aviation, labels airfields as “national assets“, and that once closed they “will never be replaced” – a statement primarily based on the complex planning system currently operating in the UK.

Many of the sites identified by the BBC have already been reduced to a holding status, or with minimal military activity anyway. In most cases military flying has already ceased and in some cases, has been so for a number of years. So why are the all party group so concerned?

As highlighted previously, this is all part of a massive cost cutting exercise and streamlining of Britain’s armed forces, a move that will not only save money for the Ministry of Defence, but provide valuable space for much-needed new housing projects across the UK.

Military airfields not only employ armed forces personnel but they also employ a large number of civilians.  Many of these people live locally, and provide a great deal of income to the local economy. As such, many small towns, for example Mildenhall, could be seriously affected by any such closure of its military base. In the event that a new airfield be required, the cost of it would, even if possible, run into millions of pounds, and would take a considerable time to complete. At a time when Britain and her allies were facing increased threats from foreign nationals, is this not perhaps a dangerous policy to be considering at this particular moment in time?

Furthermore, the issue here is not just military airfields, but Britain’s airfields in general. The all-party group, led by the Right Honourable Grant Shapps MP, aims to promote jobs and growth throughout General Aviation in the UK. The group currently (April 2018) contains 150 parliamentary members, which is a record number of members, and one that highlights the depth of feeling amongst its associates.  The group’s primary aim, which covers four areas of aviation: Airfield, Airspace, Tax and Regulations and Heritage, is to safeguard Britain’s network of airfields regardless of their size or status.

The BBC report states that many of those airfields highlighted are also used by both private pilots and particularly flight training firms, who are having to move their operations abroad due to lack of suitable airfields in the UK. Along with other ‘non-commercial’ flying activities (general aviation), these account for “£3bn a year to the UK economy“, the BBC says citing Government figures.

Whilst both military and general aviation airfields are the focus of this report, there are also wider issues at stake here. Figures quoted by the group show that the closure of Britain’s (civilian) General Aviation airfields not only affects the £3bn Gross Value Added (GVA), but directly affects over 38,000 people employed largely in the Science, Technology, Engineering and Mathematics (STEM) roles. These activities they say, “provide the foundation for the much broader £60.6bn UK aviation sector“.

The general aviation situation at the moment, according to the all-party group, shows that in Surrey for example, every licensed airfield is under threat, whilst in Hertfordshire there is only one remaining licensed airfield, and in twenty-two counties across the whole of the UK, there are no licensed airfields whatsoever.

In terms of heritage, many of these airfields, and those that have closed already, are former World War Two sites, and as such have an immense  historical value to them. As we have seen many times already, many of these airfields are no longer in existence and many have been reduced to mere shells of buildings with no memorial, or little recognition of the human sacrifice made from them.

With the closure of airfields comes the knock on effect of air displays, which since the tragic events at Shoreham, have become prohibitively expensive. Owners of historic jet aircraft for example, are having to sell them abroad as they can no longer afford to fly them in this country. The drain on flying examples could, they say, lead to there being no examples of post war models left flying in this country at all. Even military supported fleets e.g the Battle of Britain Memorial Flight, the Royal Navy Historic Flight and the Army’s Historic Aircraft Flight, are having their ability to perform at airshows reduced by Government cutbacks. This is particularly worrying they say, as evidence shows that a considerably large number of armed forces recruits are gained through airshow attendance.

Promoting general aviation, and particularly Britain’s rich and diverse aviation heritage across the UK, also falls to the numerous museums located around the country.  The majority of people they say, are within an hours drive of at least one aviation museum, and whilst the majority are on former wartime sites in the east and south of the country, this figure broadly applies to the whole of the UK; one I think you’ll agree is both astonishing and reflective of the general interest in aviation in this country.

The national interest in aviation has also been heightened by the current anniversary of the founding of the Royal Air Force on April 1st 1918, but notwithstanding this, visits to these museums accounts for an estimated 2.5 million visits a year, generating over £40 million of heritage tourism revenue – a very significant figure indeed.

The purchase and storage of static aircraft for these museums is also a costly one, rents, hangar space and ground running costs are ever-increasing. Aircraft themselves are not cheap, and few museums can ill-afford to update ‘stock’ with models that are becoming more rare with each passing day. New or more recent examples are also at the base of the argument; with the forthcoming withdrawal of the Tornado for example, how many will be ‘offered’ to local small-scale museums at a reasonable price rather than dealers who will pass them on to foreign or large-scale buyers.

Furthermore, many of these museums, house archives and personal records of those who served during many of the conflicts this country and her allies have been involved in over the last 100 years. Allowing these organisations to prosper, enables future generations to access records, photographs and information, not only about world history, but in many cases family histories too.

The closure of Britain’s airfields has not just a localised impact, it has a national impact that long-term, could have serious affects not only on the aviation and tourist economy as a whole, but science and technology, the armed forces and historical sources too. Whilst the need for housing must be met, a balance must also be sought where these valuable assets are not simply stripped away and forgotten, but consideration is given to their historical and economic contributions too. We can ill-afford to let our aviation heritage be simply removed without due consideration of the financial, economic and historical consequences.

The Development of Britain’s Airfields (Part 4).

In Part 4 of the Development of Britain’s Airfields, we take a short look at the construction process and the numerous companies that were involved in building the airfield. Once a site was found in Part 3, compulsory purchase was made and the developers moved in.

Building the airfield.

The creation of airfields was set, each plan was studied, trees, shrubs and hedges were removed, ditches filled and the land leveled to a maximum gradient of 1:60.

First of all to reduce the risk of machinery being bogged down, perimeter tracks were built. This allowed the delivery of heavy loads to any part of the site, and so were originally designed to carry support vehicles rather than aircraft. One reason why so many grassed airfields had hard perimeter tracks.

With such a big workforce being drafted in, accommodation for the workers would be needed, these would generally be the huts that would be used for the aircrews and other personnel on the base once active. Drainage and dry storage was needed as a matter of urgency, and were usually a priority even before the accommodation areas.

Buildings would be built using a range of materials.

Hiding these enormous excavations was going to a headache for the authorities. How do you hide a building site covering many acres? (Average grassed stations covered 200 – 400 acres whilst those with runways were around 500 acres extending to over 1,000 by the war’s end).  Numerous strategies were tried from painting the ground to covering it with coal dust, even adding wood chip to the concrete surfaces was used all with little real impact. Any spy or reconnaissance pilot worth his salt would have spotted the works and reported back immediately.

Gradually the airfield developed. Workers worked in shifts covering a 24 hour working day, seven days a week, this meant that the construction period was relatively short and the completion rapid. By the end of the war some £200 million worth of work had been carried out involving somewhere in the region of 130,000 individuals including engineering workers, and building sub-contractors.

As the site neared completion, RAF staff would begin moving in. The stores officer or ‘Equipment manager’ would often be first, ordering the necessary supplies to accommodate the forthcoming personnel. He would usually be followed by a NAFFI and a medical officer who would officially declare the site ready for occupation. Once this had been given the ground crews would be brought in, followed by aircrews and the aircraft. Even with a newly opened site, it was rare that it was ever fully finished, often accommodation was rudimentary or cooking facilities limited. In some cases tents were the order of the day until construction was completed. Great emphasis was placed on getting the site open and operational rather than ready. In some cases ground crews, who were otherwise waiting for aircraft to arrive, would take to shovels and picks to complete or improve upon work that had been started on site.

Also the airfield needed naming. Names were usually taken from the nearest village or town, and where confusion might arise from a similar name, it could then be taken from an alternative nearby village. This is why some airfields appear to be quite distant from their respective named locations. Alternatives to this would be geographical features or alternatively local farms e.g RAF Twinwood Farm. The Americans used the system of numbering partly because (a) the American airmen were unable to pronounce accurately some of the English names and were often found getting confused by them, and (b) the American administration system made it easier to use numbers rather than names.

By now the airfield was built, or at least open, the first unit would arrive and airfield defences would be set up. Military personnel would become established and operations would soon begin. All this could occur within months, it was a massive undertaking achieved in very little time.

In the next section we look at the architecture of British airfields, how the idea of replication in design led to architectural developments, and how the demand for materials led to changes in airfield buildings.

The Development of Britain’s Airfields (Part 3).

In Part 3 of this series, we turn from the political scene of Part 2 and look at how airfields were identified, The process and methodology of airfield selection.

Choosing a site.

Choosing an airfield site during these prewar periods was especially difficult as there were many ‘unknown’ factors to predict, a factor in itself that helped determine the needs of each of the various schemes mentioned previously. However, there were a number of airfields already in situ, some used by the military and some used by civilian aviation. As remnants of the First World War, many military sites were inadequate or inappropriate for the growing future needs of the RAF, but with some work, they could be developed into workable sites as the basic infrastructure was already there in place.

As well as these RAF sites, there were also civilian airfields, which the Government considered as potential military airfields. Because civil aviation had grown amongst the wealthier members of society, although not exclusively, this meant that in the pre-war period, there were some 90 airfields*4 owned either by local councils or under private ownership. Many of these were requisitioned by the authorities, but because many were small or located very close to built-up areas, (in 1928 the Air Ministry ‘encouraged’ towns of 20,000+ inhabitants to have a municipal airport), they were not suitable for modern fighter or bomber aircraft. As a result, many of these became training or maintenance sites, some linked to aircraft production facilities, but none were ‘operational’ for fighting units.

A further group of airfields in use at this time, were those of the AA (Automobile Association – better known as a motoring organisation). The AA Landing Grounds were often ex First World War sites located near to hotels and other places of interest to the motorist. Fuel was usually supplied at, or near to, each site, and each one was ‘tested’ by an aircraft on behalf of the AA before it was granted AA status. As these sites were registered, their locations were readily available to the Germans and so they were closed and rendered unsuitable for aircraft. However, land in close proximity was occasionally used, and so a new site would be created in a similar location.

With all these sites available, one would imagine choosing a site and developing it, would be relatively straight forward, but this is far from the truth. Many of these sites were inadequate, and the process of repairing/upgrading or rectifying it was simply not going to be sufficient. Therefore, many new sites were going to be required and the process by which a site was identified, acquired and then subsequently developed was not at all straightforward. In each case the Air Ministry Directorate (AMDGW) and Air Ministries Aerodromes Board would work in very close conjunction with numerous other Government departments and interested public bodies. These would include local Electricity Boards, Drainage Boards, the Geological Survey Department and the local War Agricultural Committee, who were concerned about flooding caused by run-off from the sudden building of large expanses of concrete.

In the first instance, using an ordnance survey map, areas that were below 50 feet above sea level or above 650 feet were generally ignored, the former being prone to flooding whilst the latter suffering high levels of low cloud or hill fog. Next a circle with a radius of 1,100 yards was marked off, this had to be flat with minimal rise in the ground layer. It also had to be free from obstructions and ideally at least three miles away from any other flying location. Next officers from the Air Ministries Aerodromes Board would walk the site, field by field, recording maximum landing distances, and noting any unidentified obstacles, trees, hedges, ditches or more permanent structures that would need removal.

By September 1939, board officials had identified, examined and recorded around 4,000 possible sites in the U.K. Many would be simply filed away never to see aviation of any kind, whilst others would become famous for years to come.

Once a suitable site had been identified and examined, the local geology had to be established where possible. In the pre-war years, no consideration was given to hard runways, they didn’t exist in any real form and were not seen as needed as any aircraft of that time could happily take off from a grass strip. However, in order to prevent aircraft wheels from bogging down, or flooding closing an airfield, well-drained soils were absolutely paramount.

Once the site had been accepted, the land was requisitioned, forcibly purchased using new powers created under the Emergency Powers (Defence) Act 1939. This gave virtually immediate access and ownership of the land – with little notice to the land owner – to the Government. These powers also saw their way to reducing the ‘NIMBY*5 effect, protests against developments being side-lined through political clout.

The next stage in the process was to put the job out to tender. The difficulty here was that secrecy was of the utmost importance, and so little of the detail was released other than an approximate location. As the war progressed, the number of construction companies involved became fewer, and those that were involved more established, prime contractors being Wimpey, Laing, Taylor-Woodrow and McAlpine – all of whom went on to be major construction companies post war. That said, no major airfield would generally be completed by one single contractor, as the whole process required a wide range of skills based operations. As one completed their task, another would come in, sometimes dual operations would be carried out simultaneously. For example taxiways and access roads may have been built by Tarmac, whereas the runway may have been built by McAlpine. Accommodation areas often used ‘Nissen’, or in many USAAF cases, ‘Quonset’ huts, many of these and other ‘standard’ buildings were erected by buildings contractors whereas other more substantial buildings may have been built by John Laing and Co.

By the outbreak of war, 100 sites had been purchased, as the number was relatively small, the board were able to be ‘particular’ in their choice, something that was quickly disregarded as the war progressed.

Airfields are highly labour intensive projects requiring an enormous workforce and extensive heavy machinery, little of which were available in the early 1940s. Irish labour provided the backbone of the initial workforce, whilst heavy plant came in from the United States. At its peak there were some 60,000 men employed on airfield construction, all of whom were unable to spend their time rebuilding the devastated towns and cities of the UK.

As the war progressed, the Royal Air Force Airfield Construction Service began taking a greater role in airfield construction, diversifying away from their original role as repairers of damaged airfields sites. There would be an initial 20 squadrons created to carry out these tasks, with a further 6 being formed later in the war. With squadron numbers ranging from 5001 to 5026, they would be initially involved in the updating of older sites and the creation of ALGs, eventually taking on a much greater responsibility of airfield construction. These squadrons, were of course given great assistance by the well established Royal Engineers.

In 1942, the United States joined the European theatre sending their own Engineer Aviation Battalions to the U.K. Their task was to support these British squadrons by building their own airfields ready for the huge influx of men and machines that was about to arrive. The first site completed by the Americans and opened in 1943, was Great Saling (later renamed Andrews Field) by the 819th engineer Aviation Battalion. Not being experienced in U.K. soils, it was a steep learning curve fraught with a number of initial problems.

In 1939 there were only 60 military airfields in the UK, by 1940 this had increased to 280, almost tripling to over 720 by 1945. Between 1939 and 1945 444 airfields*2,4 new airfields were built by these organisations – an amazing feat by any standard. Using almost a third of Britain’s total construction labour force, they were often open and manned within a matter of months rather than years.

This whole process however was not fool-proof. In a number of situations sites were identified and requisitioned, but not developed. In several cases they were partly built, and in others like RAF Cottam, they were completely built but then never occupied. Some airfields were identified for USAAF use, only to be declined and then handed over to their RAF counterparts. Some US bases were never actually started but remained named and therefore official sites even though they remained as farmers fields!

The lead up to war led to a massive change in the British landscape. Keeping airfields secret led to many being built in remote areas and away from major towns. Little did the inhabitants of these quiet little villages know, but their population was about to increase, in some cases by thousands.

In the next section we look at how the airfield was built, the process of construction and the difficulties faced during this phase.
