Today it is one of the largest ammunition compounds for the United States Air Force in Western Europe for heavy munitions.

[2] RAF Welford is located in West Berkshire with a dedicated but rarely used access road leading to the station from the eastbound M4 motorway halfway between junctions 13 (A34, Newbury) and 14 (A338, Hungerford).

[3][4] In October 1943 the airfield was allocated to Ninth Air Force IX Troop Carrier Command (TCC).

[10][11] The munitions base's function is described as "at its busiest when the US government deploys bombers to a forward air station at RAF Fairford".

[15] On 31 March 1944, at 5.00am a Lancaster DV290, after returning from a flight to Nuremberg, Germany as part of an Airborne Cigar (ABC), electronic countermeasure mission, crashed on the airfield killing all eight occupants.
