Maintenance Squadron was activated in November to maintain these missiles. SAC Strategic Wings were Major Air Command Controlled, or MAJCON, units. MAJCON units could not carry a permanent history or lineage. SAC looked for a way to make its Strategic Wings permanent. 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. AFCON wings could carry a lineage and history. Strategic Air Command The 4042d was replaced by the newly constituted 410th Bombardment Wing (410th BW) on 1 February 1963. The 526th BS was replaced by the 644th Bombardment Squadron, one of the unit's World War II historical bombardment squadrons. The 46th Air Refueling Squadron and 69th Munitions Maintenance Squadron transferred to the 410th. Maintenance and security squadrons were replaced by ones with the designation of the newly established wing. Each of the new units assumed the personnel, equipment, and mission of its predecessor. Under the Dual Deputate organization, all were directly assigned to the wing, no operational or maintenance group was activated. The history, lineage and honors of the 410th Bombardment Group were temporarily bestowed upon the newly established wing upon activation. The 410th BW continued to conduct strategic bombardment training and air refueling operations to meet operational commitments of Strategic Air Command. From 1964 to 1975, the wing supported combat operations over Vietnam by rotating B-52 and KC-135 flight crews to Guam and Okinawa. In 1980, two crews assigned to the 644th Bombardment Squadron of the 410th BW (S-21 and S-31) were awarded the Mackay Trophy for "executing a nonstop, around-the-world mission with the immediate objective of locating and photographing elements of the Soviet Navy operating in the Persian Gulf. The 410th was reassigned directly to Eighth Air Force on 8 June 1988 and redesignated the 410th Wing on 1 September 1991 when SAC implemented the Objective Wing concept. On 1 June 1992, the redesignated 410th Bomb Wing was assigned to the new Air Combat Command. The wing adapted the tail code "KI" for its aircraft. The KC-135A equipped 46th Air Refueling Squadron was reassigned to the Air Mobility Command 305th Operations Group at McGuire Air Force Base, New Jersey
