During the Second World War, Cheddington Airfield opened in March 1942 as a satellite station to RAF Wing, with No.

The Eighth Air Force 44th Bombardment Group was assigned to Cheddington, and three Consolidated B-24 Liberator squadrons (66th, 67th, 68th) had arrived from the United States.

In 1944 specialist USAAF units arrived to perform special operations missions from the airfield, performing night leaflet drops over occupied areas of Europe, working with various special operations organizations, as well as electronic countermeasure (ECM) missions.

Another psychological warfare tool was forged ration cards that disrupted local economies, when bearers flooded stores for scarce food goods.

The 36th Bomb Squadron flew specially equipped B-17s and B-24s to jam enemy early warning radars and telecommunications, screen assembly and inbound flights of allied bombers, and spoof the enemy into thinking that other bomber formations (nonexistent) were assembling.
