to oversee the wing's special weapons. It received its first combat aircraft when the 336th Bombardment Squadron, with 15 Boeing B-52 Stratofortresses moved to Turner from Biggs Air Force Base, Texas where it had been one of the three squadrons of the 95th Bombardment Wing. The wing did not become fully operational until 1 June 1960 when the 919th Air Refueling Squadron, flying Boeing KC-135 Stratotankers moved to Turner from Carswell Air Force Base, Texas. Starting in 1960, one third of the squadron's aircraft were maintained on fifteen-minute alert, fully fueled and ready for combat to reduce vulnerability to a Soviet missile strike. This was increased to half the squadron's aircraft in 1962. The 4138th (and later the 484th) continued to maintain an alert commitment until deploying to Andersen Air Force Base Guam to support combat operations in Southeast Asia. In 1962, the wing's bombers began to be equipped with the GAM-77 Hound Dog and the GAM-72 Quail air-launched cruise missiles, The 4138th Airborne Missile Maintenance Squadron was activated in November to maintain these missiles. However, SAC strategic wings could not carry a permanent history or lineage and SAC looked for a way to make its Strategic Wings permanent. 484th Bombardment Wing In 1962, in order to perpetuate the lineage of many currently inactive bombardment units with illustrious World War II records, Headquarters SAC received authority from Headquarters USAF to discontinue its Major Command controlled (MAJCON) strategic wings that were equipped with combat aircraft and to activate Air Force controlled (AFCON) units, most of which were inactive at the time which could carry a lineage and history. As a result, the 4138th was replaced by the newly constituted 484th Bombardment Wing, Heavy, which assumed its mission, personnel, and equipment on 1 February 1963. Although the 484th Wing was a new organization, it continued, through temporary bestowal, the history, and honors of the World War II 484th Bombardment Group. In the same way the 824th Bombardment Squadron, one of the unit's World War II historical bomb squadrons, replaced the 336st. The 822d Medical Group, 62d Munitions Maintenance Squadron and the 919th Air Refueling Squadron were reassigned to the 484th. Component support units were replaced by units with numerical designation of the newly established wing. Under the Dual Deputate organization, all flying and maintenance squadrons were directly assigned to the wing, so no operational group element was activated. The 4138th's support group
