By the summer of 1953, the 7th AD began a series of temporary deployments of B-47 and B-36 wings from the United States to the United Kingdom. These deployments generally involved about 45 aircraft, together with about 20 KC-97 Stratofreighters which were maintained at the English bases for 90 days. At the end of the Temporary Duty (TDY), they were relieved by another SAC wing that was generally stationed at a different airfield. These deployments continued until 1955 when SAC shifted its rotational deployments to RAF Fairford and Manston was turned over to the United States Air Forces in Europe.
