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.

[1] Since its activation, the 392d has been responsible for initial qualification training, specialty code-awarding courses for Minuteman and Peacekeeper ICBM crews, as well as basic mission orientation and refresher training for Air Force Space Command commanders and staff.

[11] After the United States Space Force was formed, it established STAR Delta (Provisional), Operating Location A.
