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

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

The runway at Charterhall in the borders, breaking up after many years of use both by training units and as a motor racing circuit post war.

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.

Remains of Type 'B' fighter Pen

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

Kingscliffe airfield

One of the ‘E’ type pens found at Kings Cliffe. Adapted with rifle slits for additional defence.

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.

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.

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.

RAF Bury St Edmunds (Rougham)

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.

Former RAF Andrewsfield

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.

50 Aviation Trails Reached!

I am pleased to announce that since starting Aviation Trails four years ago, I have now reached that magic number of 50 Trails around Britain’s wartime airfields, a feat I never thought would happen.

Each Trail covers two or more sites, in some cases six, many three, covering in total, over 100 former RAF and USAAF airfields and museums around Britain.

I can honestly say its been a terrific four years, in which I have learnt a lot about Britain’s wartime past, the men and machines that flew from these places and the tragedies that occurred at so many. The development of these airfields was staggering, the process of construction, and the subsequent decay just as eye-opening. These sites and the people who used them, have changed both the British and world landscape, leaving in many cases scars that may never heal. The buildings and stretches of concrete that remain are monuments to human endurance and sacrifice, a sacrifice that we hope may never have to be repeated.

During these four years there have been several changes at many of these sites, hangars and other buildings have gone, runways are continuing to be dug up as they become prime land for development. As we speak there are numerous sites under planning proposals, whilst others are waiting in the wings to hear what their fate will be.

To compile these trails I have personally visited each and every one of these sites, even a field has a certain something when you know who stood there before you.

To all those who have visited, commented and followed me on this journey, I thank you, I hope you have enjoyed the journey back in time as much as I have writing it. I hope that through these trails, the memories of those who gave their all may live on so that future generations may know who they were and what they did, so that we may enjoy the peace we do today.

Here’s to the next 50!

Great Sampford – A disaster for the U.S. “Eagles”.

After leaving RAF Wratting Common, we turn south and head back past Haverhill towards Finchingfield. Reputedly one of the most photographed villages in England, it has a ‘chocolate box’ appeal, its quaint houses, old tea shops and village pond, reminiscent of Britain’s long and distant past. Finchingfield and this trail, are also close to the airfield at Wethersfield, and a short detour to the east, is an added bonus and a worthy addition to the trail.

This next airfield, a small satellite airfield, lies one and a half miles to the west of Great Sampford village, and five miles south-east of Saffron Walden. It is actually quite remote, with no public roads close to the site. Footpaths do cross parts of the former airfield, which is all now  completely agricultural.

As we head south we stop  off at the former airfield RAF Great Sampford.

RAF Great Sampford (Station 359)

RAF Great Sampford was a short-lived airfield, built initially as a satellite for RAF Debden, it would be used primarily by RAF Fighter Command, and later by the US Eighth Air Force. It was also used by 38 Group for paratroop training, and by the Balloon Command.

Being a satellite it was a rudimentary airfield, and accommodation was basic; utilising wooden huts as opposed to the more pleasant brick dwellings found at its parent station RAF Debden. It was very much the poorer of the airfields in the area, although by the war’s end a wooden hut would no doubt have been preferential to a cold, metal Nissen hut!

As a satellite it would be used by a small number of squadrons, No. 65 RAF, No. 133 (Eagle Squadron) RAF and No. 616 Squadron RAF. The famous Eagle Squadrons being manned by American volunteers, 133 Sqn was later renamed 336th Fighter Squadron (FS), 4th Fighter Group (FG), after their absorption into the US Army Air Force.

There were two runways at Great Sampford, one of grass and one of steel matting (Sommerfeld track), a steel mat designed by Austrian Expatriate, 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 a handful of other track types) were common on fighter, training and satellite airfields, especially in the early part of the war. It was also used extensively on forward landing grounds in Kent and later France after the Allied invasion of Normandy.

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. Some records report tail wheels being ripped off after catching in the track lattice.

At Great Sampford the steel matting was 1600 yards long, extended later to 2,000 yards, the grass strip being much shorter at just over 1,000 yards. A concrete perimeter track circumnavigated the airfield, and due to the nature of the area the airfield took on a very odd shape indeed. With many corners and little in the way of straight sections, it may have suited the longer noses of the RAF’s Spitfires well, avoiding the need to weave continuously to see passed the long engine. However, because it was small and uneven, it caused numerous problems for pilots taking off, the hedges and trees proving difficult obstacles to clear without stalling the aircraft in an attempt to get above them.

Hangars and maintenance huts were also sparse, but four blister hangars were provided as the main structures for aircraft repair and maintenance.

Opened on 14th April 1942, the first unit to use the site was No. 65 (East India) Squadron RAF who arrived the same day that it was opened. No. 65 Sqn, being veterans of both Dunkirk and the Battle of Britain, had been moved about to regroup and refit, upgrading its aircraft numerous times before settling with the Spitfire.

The Spitfire VB of 65 Sqn (who were previously based at Debden) was a modified MK.V,  the first production version of the Spitfire to have clipped wingtips, a modification that reduced the wingspan down to 32 ft but increased the roll rate and airspeed at much lower altitudes. No. 65 Squadron, would use their Spitfire VBs for low-level fighter sweeps and bomber escort duties, something that suited the clipped wing version well.

Between April and July 1942, 65 Squadron would move between Debden, Martlesham Heath and Hawkinge with short spells in between at Great Sampford. They would then have a longer spell in Kent before leaving for RAF Drem in Southern Scotland. These repeated moves were largely in response to the threat of renewed Luftwaffe attacks on the airfields of southern England, and were part of a much larger plan put into place to protect the front line squadrons.

On April 14th, the move took place, a move that was achieved under some difficulty as the squadron was called upon to participate in two Rodeo (fighter sweeps) operations. After extensive searching between Cap Gris Nez and Calais, no enemy aircraft were sighted, and so the wing returned to their various bases. At 20:00 hrs, the first 65 Sqn aircraft touched down at Great Sampford – the base was now open and operational.

The next mission would be the very next day – there was no let up for the busy flyers! “Circus 125” led by Wing Commander J. Gordon, consisted of ten aircraft from Great Sampford, who after taking off at 18:10, met with the bomber formation and escorted them to an airfield target near Gravelines. The entire mission was uneventful and the aircraft arrived safely back at Great Sampford at 19:55 hrs.

This mission pretty much set the standard for the remainder of the month. Numerous Rodeo and Circus operations saw 65 Sqn repeatedly penetrate French airspace with various sighting of, but little contact with, enemy aircraft. The first real skirmish took place on the 25th, when the Boston formation they were escorting was attacked by fourteen FW-190s. One of the Bostons was hit and subsequently crashed into the sea. Flt. Sgt. Stillwell (Red 3) of 65 Sqn threw his own dingy out to the downed crewman who seemed to make no effort to reach it – he was then assumed to be already dead.

On the April 27th, “Circus 142” took place, the escort of eight Hurricane bombers who were attacking St. Omer aerodrome. Three sections ‘Red’, ‘White’ and ‘Blue’ made up 65 Squadron’s section of the Wing, and consisted of both Rhodesian, Czech and British airmen. The Wing flew across the Channel at 15,000 ft, and when on approach to the target, they were attacked by 50-60 FW-190s. In the ensuing dogfight F/O. D. Davies, in Spitfire #W3461; P/O. Tom Grantham (s/n: 80281) flying Spitfire #BL442, and P/O. Frederick Haslett (s/n: 80143) in Spitfire #AB401, were all reported missing presumed dead. It was thought that both F/O. Davies and P/O. Grantham may have collided as they were together when they went down, P/O. Grantham was just 19 years of age.

There were no further losses that month although operations continued up until the last day. In all, 21 operations had been flown in which 2 enemy aircraft were destroyed, 1 was a probable and 1 was damaged. April proved to be a record month in terms of operational flying hours for every pilot below the rank of Squadron Leader, the successes of which though, were marred by the sad events of the 27th and the loss of three colleagues.

On the 28th, their last day of this, the first of several stays at Great Sampford, a congratulatory message came though from the Air Officer Commanding No. 11 Group, “Well done the Debden Wing”, which went some way to lighten the atmosphere before the new month set in.*1

It was three months later on July 29th 1942, that 65 Squadron would depart Great Sampford for the last time, and the next squadron would arrive, the Spitfire VIs of No. 616 Squadron RAF.

No. 616 Sqn were formed prior to the declaration of war in November 1938. An Auxiliary Air Force Unit, it too took part in supporting both the Dunkirk evacuation and the early days of the Battle of Britain. Now, at Great Sampford, it had been given the high altitude Spitfire, the MK. Vl, an attempt by Supermarine to tackle the Luftwaffe’s high altitude bombers, and quite the opposite to the VBs of 65 Sqn – these Spitfires had extended wingtips!

616 Squadron would, like 65 Sqn before them, spend July to September yo-yoing between Great Sampford and the airfields further south, Ipswich and Hawkinge, before departing Great Sampford for the final time on September 23rd 1942 for RAF Tangmere. Whilst here at Great Sampford, they would perform fighter sweeps, bomber escort and air patrols over northern France, engaging with the enemy on numerous occasions.

On the same day as 616 Sqn departed, the last operational unit would arrive at Great Sampford, the U.S. volunteer squadron, 133 Squadron known as one of the ‘Eagle Squadrons’. Being one of three squadrons manned totally by American crews, it had been on the front line serving at RAF Biggin Hill and RAF Martlesham Heath before arriving here at Great Sampford. Whilst some British RAF ground crews helped servicing and maintenance, the aircrew were entirely US, and crews were regularly changed as losses were incurred or crews were transferred out.

Many of these new recruits came in from other units. Ground crews coming into Great Sampford would have to get the train to Saffron Walden where they were met by a small truck who would take them to RAF Debden for a meal and freshen up. Afterwards they were transferred, again by truck, the few miles here to Great Sampford, the transformation was astonishing! In the words of many of those who were stationed here, “there was nothing ‘great’ about Great Sampford!”*2 Also flying Spitfire VBs, they were to quickly replace them with the MK.IX, a Spitfire that was essentially a MK.V with an updated engine. Having a higher ceiling than the FW-190 and being marginally faster, its improved performance took the Luftwaffe by complete surprise.

It would be a short-lived stay at Great Sampford though, as 133 Sqn RAF were disbanded on the 29th September, being renumbered as 336th FS, 4th FG, USAAF, and officially becoming US Air Force personnel. They were no longer volunteers of the Royal Air Force.

Just three days before this final transfer, on September 26th 1942, 133 Sqn would suffer a major disaster, and one that almost wiped out the entire squadron.

A small force of seventy-five B-17s from the 92nd BG, 97th BG and the 301st BG, were to mount raids on Cherbourg and the airfields at Maupertus and Morlaix, when the weather closed in. The 301st BG were recalled as their fighter escort failed to materialise, and the 97th BG were ineffective as cloud had prevented bombing to take place. The RAF’s 133 (Eagle) Sqn were to provide twelve aircraft (plus two spares) to escort the bombers on these raids. After refuelling and a rather vague briefing at RAF Bolt Head in Devon, they set off. Unbeknown to them at the time, the two pilots instructed to stay behind, P/O. Don Gentile and P/O. Erwin Miller, had a guardian angel watching over them that day.

During talks with P/O. Beaty, it was ascertained that the Spitfires had flown out above 10/10th cloud cover and so were unable to see any ground features, thus not being able to gain a true understanding of where they were. Added to that, a 100 mph north-easterly wind blew the aircraft far off course into the bay of Biscay. Finding the bombers after 45 minutes of searching, the flight set for home and reduced their altitude to below the cloud for bearings. Being over land they searched for the airfield, all the time getting low on fuel. Instead of being over Cornwall however, where they thought they were, they were in fact over Brest, a heavily defended port, and in the words of 2nd Lt. Erwin Miller – “all Hell broke loose.” *3

In the subsequent battle, all but one of 133 Sqn aircraft were lost, with four pilots being killed.  P/O. William H. Baker Jr (O-885113) in Spitfire #BS446; P/O. Gene Neville (O-885129) in Spitfire #BS140 – Millers replacement; P/O. Leonard Ryerson (O-885137) in Spitfire #BS275 and P/O. Dennis Smith (O-885128) in Spitfire #BS294.

Only one pilot managed to return, P/O. Robert ‘Bob’ Beatty,  who crash landing his Spitfire at Kingsbridge in Devon after he too ran out of fuel. During the crash he sustained severe injuries but luckily survived his ordeal. From his debriefing it was thought that several others managed to land either on the island of Ouissant or on the French mainland. Of these, six were known to have been captured and taken prisoners of war, one of whom, F/Lt. Edward Brettell  DFC was executed for his part in the Great Escape from Stalag Luft III. A full report of the events of that day are available in an additional page.

There would be no further operational flying take place for the rest of the month for 133 Sqn – all in all it was a disastrous end for them, and to their spell as RAF aircrew.*4

Because these marks of Spitfire were in short supply, the remainder of the Squadron were re-equipped with the former MK.VBs, a model they retained into 1943 before replacing them with the bigger and heavier Republic P-47 ‘Thunderbolts’.

As a result of the losses, the dynamics of the group would change. The cohesive nature of the men who had been together for so long, was now broken and the base took on a very different atmosphere.

The effect on those left behind was devastating, morale slumped, and in an attempt to raise it, Donald ‘Don’ Blakeslee ordered the remaining pilots to line up along the eastern perimeter track and take off in formation; something that had been considered virtually impossible due to its short length, uneven surface and rather awkwardly placed trees along its boundary. Blakeslee, who became a legendary fighter pilot with both 133 Sqn and later the 4th Fighter Group (FG), led the group in true American Style, getting all the aircraft off the ground without any mishaps. Heading for Debden, they formed up, and flew directly over the station at below 500 feet, shaking windows and impressing those on the ground with precision flying that took as much out of the pilots as did air to air combat.

That night, the mess hall at Debden, was awash with celebrations as 133 Squadron pilots enjoyed the limelight they had for so long deserved.

On the next day, September 29th, the crews packed their personal belongings and departed Great Sampford for the comforts of Debden, where an official handover took place. General Carl Spaatz and Air Chief Marshal Sir Sholto Douglas, witnessing the official transfer of the three Eagle Squadrons to the United States Air Eighth Air Force, a move that on the whole, pleased the American airmen.

From then on, Great Sampford would remain under control of the USAAF, being used as a satellite for the 4th FG at Debden, but without any permanent residents. The occasional flight of Spitfires or P-47s would land here whilst on detachment or away pending a Luftwaffe attack. In the early stages of 1943, the Americans decided that Great Sampford (renamed Station 359 as per US designations) was no longer suitable for their needs as it wouldn’t accommodate either the  P-38s or the P-47s due to its awkward size and shape. By February 1943 they had pulled out, and Great Sampford was returned to RAF ownership. By March 1943 the airfield now surplus to flying requirements, was closed, used only by a large selection of RAF Regiments training in airfield defence, Guard of Honour duties and VIP Security. The station eventually closed in August 1944.

However, this closure was not the end for Great Sampford. With paratroop operations progressing in Europe, the airfield was put back into use on 6th December 1944 by 620 Sqn in Operation ‘Vigour‘.

No. 38 Group, in need of practice areas, had acquired the airfield, and were dropping SAS paratroops into the site. This flight preceded another similar activity the following day where Horsa gliders pulled by 620 Sqn Stirlings, took part in Operation ‘Recurrent‘; a cross-country flight from RAF Dunmow in Essex. This flight culminated with the Horsas being released and landing here at Great Sampford. These activities continued throughout the appalling winter of 1944 / 45, and into the following months. In March, in the lead up to Operation ‘Varsity‘ the allied crossing of the Rhine, there was further activity in the skies of this small grass strip. Operation ‘Riff Raff‘  saw yet more paratroops and gliders at Great Sampford, whilst in November 1945, after the war’s end, Operation ‘Share-Out‘ saw the final use of Great Sampford by the paratroops. No. 620 Squadron, who had been based at RAF Dunmow, were now winding down themselves and their use of Great Sampford ceased virtually overnight.

Since then, Great Sampford has become completely agricultural, the perimeter track virtually all that remains of this small but rather interesting site. It lies in a remote area, fed only by farm tracks and small footpaths. The tracks, now a fraction of their original size, still weave their way around the airfield as they did for that short, but busy time, in the mid 1940s.

Regretfully the airfield and its unique history has all but passed into the history books, and rather sadly, no memorial marks the airfield, even though many airmen were lost during  the many sorties in those dark days of the war-torn years of the 1940s.

We depart Great Sampford heading off once more, the airfields of Essex and East Anglia beckoning. As we move off, we spare a thought for those for whom this was the last view they had of ‘home’, and of those who never came back to this quiet and remote part of the world.

Operation ‘Fuller’ – “The Channel Dash”.

On 12th February 1942, 18 young men took off on a daring mission from RAF Manston, in outdated and out gunned biplanes, to attack the German fleet sailing through the English Channel.

Leaving Brest harbour, a force of mighty ships including the Scharnhorst, Gneisenau and Prinz Eugen, attempted a break out, supported by sixty-six surface vessels and 250 aircraft, they were to head north through the Channel out into the North Sea and homeward to Germany where they could receive valuable repairs.

The British, fearing such an attempt, had prepared six Fairy Swordfish of 825 Naval Air Squadron at nearby RAF Manston in readiness for the breakout. Ageing biplanes, they were no match for the Luftwaffe’s fast and more dominant fighters, nor the defensive guns of the mighty German fleet they were hoping to attack.

(© IWM A 5828)

In the cold winter of 1942, the Swordfish were kept ready, engines warmed and torpedoes armed, when suddenly and unexpectedly, at 12:25 on the 12th February, the fleet was sighted. They could no longer wait, and instead of attacking as planned at night, they would have to attack during the day, and so the order was given. The crews started their engines and set off on their daring and suicidal mission.

Shortly after take off, the escort arrived, merely ten Spitfires from No. 72 Squadron RAF, led by Squadron Leader Brian Kingcombe, and not the five Spitfire squadrons promised. The six Swordfish, led by  Lt. Cdr. Eugene Esmonde, dived to 50 feet and began their attack. Hoping to fly below the level of the anti-aircraft guns each of the six Swordfish flew gallantly toward their targets. Eventually hit and badly damaged, they pressed home their attacks, but they were out-gunned, and out performed, and just twenty minutes after the attack began, all six had fallen victim to the German guns. No torpedoes had struck home.

Of the eighteen men who took off that day, only five were to survive.

Leading the attack, Lt. Cdr. Esmonde was warded the V.C. Posthumously, he had previously been awarded the Distinguished Service Order for his part in the attack on the Battleship Bismark; an award that also went to: S/Lt. B Rose, S/Lt. E Lee, S/Lt. C Kingsmill, and S/Lt. R Samples. Flying with them, L/A. D. Bunce was awarded the Conspicuous Gallantry Medal and twelve of the airmen were mentioned in dispatches.

In their honour and to commemorate the brave attempt to hit the German fleet that day, a memorial was erected in Ramsgate Harbour, the names of the eighteen men are listed where their story is inscribed for eternity.

January 1st 1945 – Loss of Mosquito PZ340

On the afternoon of January 1st 1945, Mosquito FB.VI #PZ340, ‘HB-Z’ took off from RAF West Raynham, according to the Operational Record Book it was assigned to a “high level bomber support” sortie over Heligoland, unusual as these Mosquitoes were not pressurised models. The pilot, F/O Ian George Walker (s/n: 156104) and navigator/wireless operator F/O. Joseph Ridley Watkins (s/n: 152875), had only just been brought together, F/O Watkins, from Wanstead in Essex, normally being based with 141 Squadron, but on attachment to 239 Squadron, when the flight took place.

On return, from the mission, the aircraft crashed near to Narford Hall, an Eighteenth Century stately home located a short distance to the north-east of RAF Marham in Norfolk. Whilst not confirmed, it is thought the crash was caused by an instrument failure, a crash that resulted in both airmen being killed.

Following the accident, F/O. Walker was returned to his home town and was buried in St. Michael’s Cemetery in Dumfries. F/O Watkins however, was buried locally, in nearby St. Andrew’s Church, Little Massingham not far from RAF Great Massingham. Both airmen were only 21 years of age.

The Mosquito, a Hatfield manufactured aircraft, was produced under contract 555/C.23(a), and was an aircraft designed for ‘intruder’ strike missions, it was the most commonly used variant of all Mosquitoes.  239 Squadron was in the process of replacing these examples with the MK. XXX before its disbandment on July 1st 1945.

Little Massingham St. Andrew's Church

F/O Watkins died on January 1st 1945 after the Mosquito he was in crashed near to RAF Marham, Norfolk. He rests in St. Andrew’s Church yard, Little Massingham.
