USAAF use In October 1943 the airfield was allocated to
Ninth Air Force IX Troop Carrier Command (TCC). While under USAAF control, Welford was known as
USAAF Station AAF-474.
315th Troop Carrier Group The
315th Troop Carrier Group arrived at Welford on 6 November 1943 from
RAF Aldermaston flying
Douglas C-47 Skytrain and
Douglas C-53 Skytroopers. Its squadrons and fuselage codes were: • 34th Troop Carrier Squadron (NM) • 43d Troop Carrier Squadron (UA) • 309th Troop Carrier Squadron (M6) • 310th Troop Carrier Squadron (4A) The 315th TCG was part of the 52nd Troop Carrier Wing. On 7 February 1944 the group was transferred to
RAF Spanhoe. • 75th Troop Carrier Squadron (SH) •
76th Troop Carrier Squadron (CW) •
77th Troop Carrier Squadron (IB) •
78th Troop Carrier Squadron (CM) The 435th TCG was assigned to the
53d Troop Carrier Wing. In early February 1945 the group was moved to an Advanced Landing Ground at Breigny, France (A-48). At the same time a short rail spur was opened, connecting the site with transfer sidings near
Welford Park station on the
Lambourn Valley Railway; the USAF used the line until the 1970s, and the track was lifted sometime after 1973. During April 1995 the base was handed back to the RAF, only for it to be returned to USAF control. In 2009, USAF staffing at Welford was reduced as part of USAF-wide budgetary adjustments. The munitions base is described as "at its busiest when the US government deploys bombers to a forward air station at
RAF Fairford". The bombers at RAF Fairford can include B-1, B-2 and B-52. In May 2019, the USAF moved of explosives to RAF Welford, then the second-largest ammunition store in
United States Air Forces in Europe – Air Forces Africa (USAFE). ==The crash of Lancaster DV290==
