The 819th Strategic Aerospace Division is an inactive United States Air Force formation. Its last assignment was with Second Air Force of Strategic Air Command (SAC) at Dyess Air Force Base, Texas, where it was inactivated on 2 July 1966. The division was activated as the 819th Air Division in 1956 to command two Boeing B-47 Stratojet wings that SAC was organizing at Dyess. "The division emphasized flying operations, flying training, and aircraft maintenance. In fulfilling its duties, the 819th participated in numerous tactical training exercises throughout its existence." Until April 1961, the division also provided supporting services at Dyess through its 819th Air Base Group. After 1961, the wing became an operational headquarters for wings located at bases in the southwestern United States. It added SM-65 Atlas ICBMs, Boeing B-52 Stratofortresss and Boeing KC-135 Stratotankers in 1962, and its B-47s were phased out by the middle of the following year. The missile mission brought with it a new name, 819th Strategic Aerospace Division. The division was inactivated in 1966 and its component wings were assigned to other SAC divisions. (en)
