392d Combat Training Squadron
Its first predecessor was the 592d Bombardment Squadron, which trained aircrews on Boeing B-17 Flying Fortresses during World War II.[1][2] After initial organization and equipping with Boeing B-17 Flying Fortress heavy bombers, the squadron moved to Moses Lake Army Air Base, Washington.[1] However, the Army Air Forces was finding that standard military units, based on relatively inflexible tables of organization were not well adapted to the training mission.[9] The 392d Missile Training Squadron was activated at Cooke Air Force Base, California on 15 September 1957.Instead, it remained inactive until 1 July 1993, when it was redesignated the 392d Space and Missile Training Squadron and activated at Vandenberg Air Force Base, California.[11] After the United States Space Force was formed, it established STAR Delta (Provisional), Operating Location A.
