The United States Air Force's 508th Air Refueling Squadron was an air refueling unit that operated the Boeing KB-29 at Turner AFB, Georgia. It was last active on 1 July 1957 Established in 1953 to provide strategic air refueling for the 508th Strategic Fighter Wing. Advances in technology soon made escort fighter wings obsolete. A single atomic bomb had more explosive power than all the conventional bombs dropped during all of World War II, so only one of them could certainly destroy a target far more effectively than a formation of bombers. SAC's missions were based on the use of an individual airplane, not a formation of them.
