Folkingham was known as USAAF Station AAF-484 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 "FK".
US personnel started to arrive in January 1944 to prepare for the 313th Troop Carrier Group scheduled to transfer from Trapani/Milo Airfield, Sicily. On 5 February it opened as a USAAF IX Troop Carrier Command station flying four squadrons of C-47s. Operational squadrons and fuselage codes were:
However, at the end of February 1945, the group began its move to a new base in France at Achiet, although the last elements did not leave until well into March.
RAF Maintenance Command
Folkingham was retained by the USAAF although most personnel had departed by mid-April. The station was closed in 1947. With the facility released from military control, the runway was used for development testing of the new BRM 16 cylinder 1.5 litre racing car which was presented before the press for the first time on 15 December 1949, at Folkingham airfield. A BRM engine test house and other facilities were later built there.
RAF Folkingham later served as a post-war PGM-17 Thor Intermediate Range Ballistic Missile base with 3 IRBM launchers operated by No. 223 Squadron RAF. With the reactivation of the site in late 1958, BRM was relocated to RAF North Witham.
Current use
On the closure of the Thor site, British Racing Motors moved back and its later cars were tested at Folkingham, but only remained for a few years. In the late 1960s the runways and some nissen huts were used by Lincolnshire Police as a driver training and skid pan area. In the mid-1960s the testing track closed and the airfield was sold off to agricultural interests. Today the airfield is largely used by agriculture. Most of the runways and perimeter track were removed after the sale of the airfield by BRM for hardcore aggregate, with some single-lane agricultural roads remaining that generally outlines the former concreted area. No evidence of the technical site located to the north-east of the airfield remains. Evidence of some dispersed personnel sites appear to the north and north-east of the airfield, with some abandoned concrete roads now in abandoned, overgrown areas. The southern half of the airfield partially remains containing several single and double-loop handstands, along with a full-width length of the 00-18 north-south main runway. The runway now serves as a vehicle compound for Nelson M Green & Sons Ltd, for the storage of decommissioned agricultural vehicles, lorries and other equipment. The vehicles, many often rare and long out of production, are stored for the resale of their spare parts. The abandoned hulks also line the sides of the remaining perimeter track along with several of the old dispersal loops. The wartime bomb dump exists, although it is now a forested area still containing concrete disused bomb stores, evidence of which can be seen by the pattern of vegetation that has overgrown and reclaimed the facility. The remains of the three post war Thor missile pads are the most prominent military features remaining on the airfield, their heavily reinforced concrete areas making them difficult and uneconomical to remove for the small amount of aggregate that can be reclaimed from them.
