In the Summer of 1952, with the start of the Cold War and increase in strength by the US 3rd Airforce in Europe, RAF Wethersfield was re-activated and became home to the 20th Fighter Bomber Wing.
From 1970 to 1979 although the USAF 3rd Airforce remained at Wethersfield it was essentially back to care and maintenance, the primary caretakers being The 66th Tactical Reconnaissance Wing, from Upper Heyford which was inactivated and elements were moved to Wethersfield. As a result, Wethersfield became a Dispersed Operations Base until June 1970, when the base mission was changed to that of Standby Deployment Base, ready to support augmentation forces if directed.
