RAF Warboys was a World War II Royal Air Force heavy bomber station, situated just outside the village of Warboys in Huntingdonshire (now Cambridgeshire).
During the early years of the war, Warboys was a relatively conventional bomber station which was supplemented with the addition of an exceptionally long main runway measuring 6,290 feet. Construction of this runway resulted in the closure of the nearby road to Huntingdon during the war years.
The station was allocated to No.3 Group in August 1942 and became home to the Wellington bombers of No.156 squadron (freeing up the station at RAF Alconbury to be taken over by the USAAF). Later that month, RAF Warboys became one of the original Pathfinder Force stations.
In January 1943, the base converted to Avro Lancaster bombers, which remained at the site until March 1944, when the aircraft were relocated to nearby RAF Upwood.
Located on the north side of the site was the battle headquarters bunker, defended by a pair of mushroom shaped F.C Construction type pillboxes (also known as Oakington or Fairlop type pillboxes), one of which remains in good condition in 2009.
The airfield's bomb stores were located to the west of the airfield and to the north lay a machine gun butt, used for testing, discharge and alignment of aircraft machine guns.
Domestic, mess and communal sites were dispersed to the South East of the airfield either side of the modern A141 on the borders of the neighbouring village of Old Hurst. At least 11 separate dispersed locations provided maximum accommodation for 1,959 male and 291 female personnel.
In 1960, the former airfield became a Bristol Bloodhound air defence missile site, later withdrawn in 1963. The site was then sold back into private ownership and returned to largely agricultural use, with a small industrial estate developing on the southern corner of the former runways.
