Royal Air Force Greenham Common or RAF Greenham Common is a former Royal Air Force station in the civil parishes of Greenham and Thatcham in the English county of Berkshire. The airfield was southeast of Newbury, about west of London. Opened in 1942, it was used by the United States Air Force during the Second World War and during the Cold War, and later as a base for nuclear weapons. After the Cold War ended, it was closed in September 1992. The airfield was also known for the Greenham Common Women's Peace Camp held outside its gates in the 1980s in protest against the stationing of cruise missiles on the base. In 1997 Greenham Common was designated as public parkland. History Second World War The Greenham Lodge Estate, which was set in the midst on Greenham Common, was requisitioned by the Air Ministry in 1941. The first arrival was the U.S. Army Air Forces (USAAF) 51st Troop Carrier Wing Headquarters, arriving in September 1942. The 51st TCW controlled 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. An area to the east of Bowdown House, a mansion on the northeast end of the airfield, was used as "bomb stores". The 51st TCW HQ followed its groups to North Africa as part of Operation Torch in November 1942. 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. 354th Fighter Group 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 Army Air Field, Oregon and they were informed they were to fly the North American P-51 Mustang. The unit transferred to RAF Lashenden in April 1944. 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
