RAF Station Greenham Common is a former military airfield in Berkshire, England. The airfield is located approximately 2 miles (3.2 km) south-southwest of Thatcham; about 50 miles (80 km) west of London

Opened in 1942, it was used by both the Royal Air Force and United States Army (later Air) Force during World War II and the Cold War. After the Cold War ended it was closed in 1993.

The airfield was also known for the Greenham Common Women's Peace Camp held outside its gates in the 1980s.

Today the airfield is slowly being dismantled from its military past.


Pre-military history

Greenham Common was a piece of common land. It was used for troop movements during the English Civil War and in the nineteenth century.

World War II

Greenham Common airfield was one of several wartime airfields in the Salisbury Plain area and was originally intended for use as an RAF Bomber Command Operational Training Unit. It was built to the Class A airfieldstandard, the main feature of which was a set of three converging runways each containing a concrete runway for takeoffs and landings, optimally placed at 60 degree angles to each other in a triangular pattern connecting to an enclosing perimeter track, of a standard width of 50 feet.

The land for the airfield was acquired in May 1941 and the runways were built in early 1942 with one main and two secondary runways with assorted loop and pan dispersal hardstands connecting to an enclosing perimeter track, of a standard width of 50 feet.

The ground support station was constructed largely of Nissen huts of various sizes. The support station was where the group and ground station commanders and squadron headquarters and orderly rooms were located. Also on the ground station were where the mess facilities; chapel; hospital; mission briefing and debriefing; armory; life support; parachute rigging; supply warehouses; station and airfield security; motor pool and the other ground support functions necessary to support the air operations of the group. These facilities were all connected by a network of single path support roads.

The technical site, connected to the ground station and airfield consisted of at least two T-2 type hangars and various organizational, component and field maintenance shops along with the crew chiefs and other personnel necessary to keep the aircraft airworthy and to quickly repair light and moderate battle damage. Aircraft severely damaged in combat were sent to repair depots for major structural repair. The Ammunition dump was located outside of the perimeter track surrounded by large dirt mounds and concrete storage pens.

Seven domestic accommodation sites were constructed dispersed mostly off the eastern end of the airfield, but within a mile or so of the technical support site, also using clusters of Maycrete or Nissen huts. The Huts were either connected, set up end-to-end or built singly and made of prefabricated corrugated iron with a door and two small windows at the front and back. They provided accommodation for 2,400 personnel, including communal and a sick quarters.

During airborne operations, when large numbers of airborne parachutists were moved to the airfield, tents would be pitched on the interior grass regions of the airfield, or wherever space could be found to accommodate the airborne forces for the short time they would be bivouacked at the station prior to the operation.

The airfield was opened in June 1942 as a satellite for RAF Aldermaston, with operational control later being transferred to RAF Andover in late 1942. In the absence of American units during the first nine months of 1943, the airfield was made available to RAF trainer units. Airspeed Oxfords were often to be seen landing and taking off from its runways, until the airfield reverted to USAAF control in October.


In late 1943, Greenham Common airfield was turned over to the USAAF Ninth Air Force. An American advance party soon arrived to ready the airfield for the incoming units. Greenham Common was known as USAAF Station AAF-486 for security reasons by the USAAF during the war, and by which it was referred to instead of location. It's USAAF Station Code was "GC".

The first arrival while the airfield was still under construction was the 51st Troop Carrier Wing Headquarters, arriving in September 1942. The 51st TCW was a non-flying organisation, controlling the three troop carrier groups at RAF Keevil (62nd TCG), RAF Aldermaston (60th TCG) and RAF Ramsbury (64th TCG) as part of Twelfth Air Force. The Wing Headquarters was located in requisitioned Bowdown House, a mansion on the northeast end of the airfield, and made use of the runways for its communication and courier flights.

The 51st TCW HQ followed its groups to North Africa as part of Operation Torch in November 1942.

354th Fighter Group

Republic P-47D of the 397th Fighter Squadron

As troop carrier groups began arriving in the UK in late 1943 and deployed in the Greenham Area, Greenham Common was one of the airfields used by the Ninth Air Force for fighter groups arriving from the United States.

On 4 November the 354th Fighter Group arrived from Portland AAF, Oregon and they were informed they were to fly the North American P-51B Mustang. This was a change of equipment for the group, as they had trained with Bell P-39 Airacobras. The Mustang was a far more capable aircraft, with excellent performance that was required to escort the heavy bomb groups of the Eighth Air Force.

The 354th FG stayed at Greenham Common for only a few days, being transferred to RAF Boxted in Essex on 13 November. Headquarters of Ninth Air Force's 70th Fighter Wing of IX Tactical Air Command arrived from Paine AAF, Washington at Greenham Common on 29 November, staying just a few days before also moving on to RAF Boxted on 6 December.

368th Fighter Group

A few weeks later on 13 January 1944, the 368th Fighter Group arrived from Farmingdale, New York, flying Republic P-47 Thunderbolts. They had the following fighter squadrons and fuselage codes:

  • 395th Fighter Squadron (A7)
  • 396th Fighter Squadron (C2)
  • 397th Fighter Squadron (D3)

The 368th was a group of Ninth Air Force's 71st Fighter Wing, IX Tactical Air Command.

On 14 March, after two months at the base, 48 of the group's aircraft took off on their first combat mission, flying a fighter sweep over the coast of France. The group headquarters had previously been alerted to prepare to move to another base, as IX Troop Carrier Command finally required Greenham Common for a troop carrier group. The 368th FG moved to RAF Chilbolton the next day.

Literally as the 368th FG was moving out, the 438th Troop Carrier Group was flying into Greenham Common from RAF Langar. Flying Douglas C-47 Skytrains, they had the following Troop Carrier squadrons and fuselage codes:

  • 87th Troop Carrier Squadron (3X)
  • 88th Troop Carrier Squadron (M2)
  • 89th Troop Carrier Squadron (4U)
  • 90th Troop Carrier Squadron (Q7)

The 368th was a group of Ninth Air Force's 53rd Troop Carrier Wing of IX Troop Carrier Command. The squadrons had 18 airplanes apiece, mostly C-47s but also a few C-53s. In addition to the airfield, the heathland immediately to the east, Greenham Common, was earmarked as an assembly point for WACO CG-4A Assault Gliders which were received from the US in packing crates. When assembled, the gliders were towed to the airfield runways for dispersal to other airfields.

Glider assembly averaged about 15 per day by early 1944, increasing to 50 per day by September 1944. As at all troop carrier bases where the use of gliders was envisioned, some 800 feet (240 m) of pierced steel planking runway strips was laid at each of the main runway ends to allow the marshalling of gliders.

At Greenham Common the 438th TCG trained for and participated in airborne operations, flew resupply and reinforcement missions to combat zones, evacuated casualties, and hauled freight.

D-Day operations

For its superior flying skills exhibited in extensive daylight and night training, the 438th TCG was selected to lead the IX Troop Carrier Command force in the American airborne landings in Normandy. Prior to the launch, both General Dwight D. Eisenhower and Lt Gen Lewis H. Brereton, Ninth Air Force Commanding General, visited Greenham Common to watch preparations and speak with the troops of the 502nd Parachute Infantry Regiment.

Eighty-one aircraft, divided into two serials of 36 and 45 aircraft and led by the 87th Troop Carrier Squadron (3X), took off from the main runway in 15 minutes, starting at 23:48 hours on 5 June. Despite radio black-out, overloaded aircraft, low cloud cover and lack of marked drop zones, they carried 1,430 men of the US 101st Airborne Division's 502nd Parachute Infantry Regiment, who were dropped soon after midnight in the area northwest of Carentan. Glider-borne reinforcement missions followed, and for its determined and successful work the group received a Distinguished Unit Citation.

Losses amounted to one C-47 and a C-53, both lost to flak on 7 June.

Operation Dragoon

On 20 July the air echelons of the 87th, 88th and 89th Troop Carrier Squadrons departed for Canino airbase in Italy in preparation for the August invasion of Southern France, Operation Dragoon. In the invasion, the squadrons dropped paratroops and towed gliders that carried reinforcements. The group also hauled freight in Italy.

The 90th TCS stayed in the UK and operated from RAF Welford until the rest of the groups aircraft returned from Italy on 24 August.

In the absence of the 438th, the 316th Troop Carrier Group used Greenham Common as a forward base.

Operation Market Garden

In September the 368th group helped to supply the Third Army in its push across France, and transported troops and supplies when the Allies launched the airborne operation in Holland.

As part of Operation Market Garden 90 aircraft from the 438th dropped 101st Airborne paratroopers near Eindhoven without loss on 17 September. The next day, 80 aircraft towed gliders again without loss of aircraft, although two gliders aborted and 11 C-47s suffered flak damage. However, when 40 C-47s towing 40 CG-4A Horsa Gliders left Greenham Common on 19 September, things did not go so well in adverse weather. Only half of the gliders were released in the landing zone area, and one C-47 was shot down and several gliders lost.

A further glider mission by a similar number of aircraft fared no better and another C-47 was lost. Re-supply missions were flown on 20 September and 21 September to Overasselt and Son.

During the Battle of the Bulge (December 1944–January 1945), the group, again headed by the 87th Troop Carrier Squadron, flew air supply missions to battle areas, including the first two flights into beleaguered Bastogne. In February 1945 the groups of the 53d TCW were moved to France, the 438th going to A-79 Advanced Landing Ground at Pronses.

On the continent, the 438th TCG used the following Advanced Landing Grounds:

  • A-79 Pronses, France Feb 1945
  • B-48 Amiens/Glisy, France May – 3 Aug 1945

The group evacuated Allied prisoners of war after V-E Day. It returned to Baer AAF Indiana on 16 September 1945.

Post-war RAF use

With the departure of the USAAF troop carrier squadrons, glider assembly continued on and off until April 1945; two of the airfield hangars were used for this work. In total, over 4,000 gliders were assembled at Crookham Common and flown out of Greenham.

The airfield continued to be used by Ninth Air Force until the RAF took control in June 1945. The RAF used the Greenham Common airfield as an RAF basic training centre until being closed in June 1946, with the facility being put into care and maintenance status.

The airfield was inactive for the next five years, and would probably have remained so but for the sudden escalation in tension between the Soviet Union and its World War II Allies in what later became known as the Cold War.

Cold War

In response to the perceived threat by the Soviet Union, especially after the 1948 Berlin Blockade and the 1950 invasion of South Korea by the Korean People's Army, on 23 April 1951, RAF Greenham Common was made available to the United States Air Force by the British Ministry of Defence as a Strategic Air Command base, with joint operations with the Royal Air Force units.

Between 1951 and 1953, major construction work was performed on the base, as post-war jet bombers required a much greater runway length for take off versus those of World War II, and the Strategic Air Command spent over £2 million building a new 10,000 feet (3,000 m)-long runway that extended onto Greenham Common and across the A339. To give the desired 10,000-foot (3,000 m) run, the A339 was diverted, and a new length of roadway was built to the south through Sandelford Common. In addition to the runway, massive new hard-standings were built, and extensive rebuilding also occurred for ramp areas and new structures.

Two 1,000 feet (300 m) overshoots were added to the runway in 1958. To the south-west of the runway, a new munitions area was built. Eight 1 million gallon underground fuel tanks were also constructed at the base.

Strategic Air Command

In the post-World War II years, the United States Strategic Air Command was based at three major airfields in eastern England: RAF Lakenheath, RAF Marham and RAF Sculthorpe. The increasing tension of the Cold War led to a re-evaluation of these deployments and a move further west, behind RAF fighter forces, to RAF Greenham Common, RAF Brize Norton, RAF Upper Heyford and RAF Fairford.

The airfield came under Strategic Air Command's 7th Air Division, with the 3909th Combat Support Group as its administrative unit on the base, responsible for all non-flying activities as well as maintenance and logistical support of the flying units attached to RAF Greenham Common.

The initial bomber wing deployed was the 303d Bombardment Wing with B-47 Stratojets, arriving on 17 March 1954 from Davis-Monthan Air Force Base in Arizona. The 303d stayed just over a month, returning on 28 April 1954. This was the first of the short-term temporary duty deployments from home bases in the US that continued intermittently over the next 10 years. Other known SAC deployments were:

  • Greenham Common Task Force (Provisional) (1 November 1955 – UNK) (ERB-29Aa and RB-50G/Es) (Electronic Reconnaissance and Countermeasures) (TDY From 97th Bombardment Wing, Shilling AFB, Kansas)
  • 97th Air Refueling Squadron (5 May 1956 – 13 July 1956)(KC-97)
    (TDY From 97th Bombardment Wing, Shilling AFB, Kansas)
  • 310th Bombardment Wing (3 October 1956 – 9 January 1957) (B-47, KC-97)
    (TDY Forbes AFB, Kansas)
  • 40th Bombardment Wing (1 July 1957 – 1 October 1957) (B-47, KC-97)
    (TDY Forbes AFB, Kansas)

In April 1958 the 90-day detachments were replaced by a three-week Reflex Alert rotation, during which the bombers did not fly, reducing the noise considerably. The runways and dispersals were further strengthened for the Boeing B-52 Stratofortress bomber, but none were based at Greenham.

From August 1960 the B-52 made periodic training visits, and a Convair B-58 Hustler arrived briefly in October 1963. Reflex operations by B-47 and KC-97s continued until1 April 1964.

Many SAC Squadrons had aircraft at RAF Greenham Common on a transitory basis without any recorded deployment to the base.

The Strategic Air Command (SAC) departed Greenham common on 30 June 1964, much to the relief of the local residents; the thundering jet bombers of SAC came no more, and for several years it was used for USAF storage and as a relief base.

United States Air Forces in Europe

The closure of US bases in France forced the reopening of RAF Greenham Common for air transport operations (Operation FRELOC) to handle materiel and personnel overflow beginning in early January 1967. In late 1967, Greenham Common was used for NATO Reforger exercises, again as a result of the withdrawal of France from the NATO integrated military alliance.

On 1 November 1968 control of RAF Greenham Common was transferred from SAC to the United States Air Forces in Europe, with the 7551st Combat Support Group having administrative control of the base. However, the base was little used, primarily being utilised as a United States Military Postal Mail sorting facility, with aircraft flying mail in from the United States, being sorted at Greenham Common, then distributed to American bases in the UK and Europe. Mail from American forces in Europe was also sent to Greenham Common and sorted there, before being flown to the United States.

Beginning in 1973 the base became the home of the International Air Tattoo, a large scale international military airshow, since relocated to RAF Fairford, approximately 40 miles (64 km) away.

The 20th Tactical Fighter Wing at RAF Upper Heyford established "Operating Location A" at Greenham Common for its F-111 fighters in 1976, using the airfield occasionally for dispersal exercises.

In 1977 the USAF announced plans to reactivate the base to house KC-135 aerial refueling tankers, due to a lack of capacity at the KC-135's main UK base, RAF Mildenhall. This led to widespread local opposition, and in 1978 the British Defence Secretary vetoed the plan.

501st Tactical Missile Wing

The Soviet deployment of the SS-20 missile from 1975 caused major concern in the NATO alliance. The longer range, greater accuracy, mobility and striking power of the new missile was perceived to alter the security of Western Europe. It was feared that the Soviet Union could launch a nuclear strike against Western Europe with a reduced threat of nuclear retaliation (i.e. compared to an attack on the continental United States). After discussions, NATO agreed to a two part strategy:

  • To pursue arms control negotiations with the Soviet Union to reduce their and the American INF arsenals.
  • To deploy in Europe from 1983 up to 464 Gryphon Ground Launched Cruise Missile or GLCMs, as well as 108 Pershing II ballistic missiles. (See also SLCM and ALCM).

The UK's share of this total was 160 missiles, 96 based at Greenham Common with four spares, and 64 at RAF Molesworth. When in June 1980 it was announced that RAF Greenham Common was to become the first site for cruise missiles, the outcry came more from Campaign for Nuclear Disarmament than the local populace.

Once more a massive new construction was undertaken as the GAMA (GLCM Alert and Maintenance Area) site was built in the southwest corner of the base. GAMA was a maximum security QRA (Quick Reaction Alert) area with 6 large above ground shelters in which fully operational cruise missiles were stored.


These shelters were specially designed and constructed to protect the GLCMs and crews against nuclear and conventional strikes. They were about 10 m high, with a reinforced 2 m thick concrete ceiling. Below was a massive titanium plate, 3 m of sand and a reinforced concrete plate. The shelters were completely covered with tons of clay. Each shelter was equipped with three hydraulic nuclear blast proof doors at both ends to assure a quick entry or exit. They were designed to withstand the blast of an air-bursting nuclear explosion above the base or a direct hit from a 2,500 lb (1,100 kg) conventional bomb.

Each shelter contained 2 LCC Launch Control Centers and 4 TEL transporter erector launchers. Each unit was mobile and supposed to leave the base in convoys to their secret preset dispersal sites. This would happen within minutes after the alert and the movement was via the local roads through the surrounding villages.

The first squadron of the 501st Tactical Missile Wing received its weapons in November 1983; they were flown onto the base by C-5As.

A series of meetings held during August and September 1986 culminated in a summit between United States President Ronald Reagan and the General Secretary of the CPSU Mikhail Gorbachev in Reykjavík, Iceland, on 11 October 1986. To the surprise of both men's advisers, the two agreed in principle to removing INF systems from Europe and to equal global limits of 100 INF missile warheads.

The United States and the Soviet Union signed the Intermediate-Range Nuclear Forces Treaty in 1987, which led to the removal of all nuclear missiles from the base. The last GLCMs at RAF Greenham Common were removed in March 1991, and the 501st TMW inactivated on 4 June 1991.

The base's last operational commander, Andrew Brookes, went on to become an aviation author.

Greenham Common Peace Camp

From 1981 "women's peace camps" were established in protest at the deployment of the cruise missiles. They came to be known as "The Greenham Women" or "peace women", and their 19-year protest drew worldwide media and public attention, often by cutting through the fences.

USAF departure and closure

On 11 September 1992, the USAF returned Greenham Common airbase to the Ministry of Defence. On 9 February 1993 the Greenham Common airbase was declared surplus to requirements by the Secretary of State for Defence and the facility was closed and put up for sale.

With the departure of the cruise missiles and the subsequent closure of the base by the MOD in 1993, the peace camps remained at the site until September 2000 to ensure the base was closed and the land returned to the public. However, the protesters no longer attracted the attention of the media as they did during the 1980s when there were some 40 camps spread around the base perimeter.

Return to civilian use

On 24 March 1997 the land was purchased by the Greenham Common Trust[1] for £7 million and returned to civilian use. A business park, named New Greenham Park[2], is sited on one portion of the former airbase and, by 2002 housed over 150 businesses. Greenham Common Trust manages its investment in the business park to produce a sustainable income that is distributed to local charities, environmental and community projects, including the artist studios, gallery and performance space housed in New Greenham Arts.

Considerable efforts have been made to restore large areas of the Common to something approaching its former natural state. A major part of this has been the removal of the runway (except for one central section) and hardstandings which were used as fill for construction of the Newbury bypass.

The Common is owned by West Berkshire Council and managed by the Council in consultation with the Greenham and Crookham Commons Commission,[3] with the general aims of nature conservation and the exercise of commoners' rights. Also working to protect this 278.61 hectare (688.45 acre) Site of Special Scientific Interest[4] and preserve the outstanding beauty of the common are the Greenham and Crookham Conservation Volunteers.

In 2008 an educational resource was launched regarding the restoration of Greenham Common and the transformation of part of the airbase to a business park. is aimed at children in primary and secondary education and their teachers.

Greenham Common Trust was awarded The Queen's Award for Enterprise:Sustainable Development in April 2008, the second time this was awarded to Greenham Common Trust.

The control tower as it stands today

Today the airfield has been dismantled from its military past. However, the bunkers and other components of the Ground Launched Cruise Missiles still remain. The 10,000' runway built by SAC in the 1950s no longer exists, with – as mentioned – a central section still in place. All of the taxiways have been removed, leaving scarred land which is being returned to a natural state. The large hangar built by SAC is in civilian use, and the large aircraft parking ramp is now used as part of the New Greenham Park complex, which has been fenced off from the rest of the former airfield. The large amount of Cold War construction which took place at Greenham Common in the 1950s essentially obliterated all evidence of the World War II airfield.

Alleged nuclear accident

On 28 February 1958 a B-47E of the 310th Bomb Wing developed problems shortly after takeoff and jettisoned its two 1,700 gallon external fuel tanks. They missed their designated safe impact area and one hit a hangar whilst the other struck the ground 65 feet (20 m) behind a parked B-47E. The parked B-47E, which was fuelled, had a pilot on board, and was carrying a 1.1 megaton (4.6 PJ) B28 nuclear bomb, was engulfed by flames. The conflagration took sixteen hours and over a million gallons of water to extinguish, partly because of the magnesium alloys used in the aircraft. Although two men were killed and eight injured, the US and UK governments kept the accident secret – as late as 1985, the British Government claimed that a taxiing aircraft had struck a parked one and that no fire was involved.

Two scientists, F.H. Cripps and A. Stimson, who both worked for the Atomic Weapons Research Establishment at Aldermaston, alleged in a secret 1961 report, released by the CND in 1996, that the fire detonated the high explosives in the nuclear weapon, that plutonium and uranium oxides were spread over a wide area – foliage up to 8 miles (13 km) away was contaminated with uranium-235 – and that they had discovered high concentrations of radioactive contamination around the air base.[5]

However, a radiological survey commissioned in 1997 by Newbury District Council and Basingstoke and Deane found no evidence of a nuclear accident at Greenham Common. The 7-month long survey was carried out by the Geosciences Advisory Unit of Southampton University and combined a helicopter-mounted gamma ray detector survey with a ground-based survey. The team analysed nearly 600 samples taken from soil, lake sediment, borehole water, house dust, runway tarmac and concrete, looking for uranium and plutonium isotopes. No evidence of an accident involving nuclear weapons damage was found at the former air force base, although the ground survey did detect some low-level uranium contamination around the Atomic Weapons Establishment at Aldermaston thought to be derived from that facility, and the helicopter survey found some anomalies around Harwell Laboratory.
