The airfield was first handed over to the United States Army Air Forces (USAAF) in 1942.

[1] RAF Little Staughton was returned to the Royal Air Force (RAF) on 1 March 1944[1] The airfield was placed into care and maintenance in 1945, and during the 1950s the United States Air Force extended the runway for use by jet aircraft in emergency circumstances.

[1] At some point the runway was shortened on the south end to the southmost taxiway with the land converted into a field.

[7] There is also a solar farm and an industrial estate reusing the old airfield buildings.

Because of the lack of redevelopment most of the Military Buildings remain including the control tower, the Airfield battle HQ, a T2 hangar and a variety of smaller buildings, some of which are in an area called 'little america' as it was the site of the American accommodation blocks, which is to the south of the airfield[8]
