in 1962. The 4239th (and later the 449th) continued to maintain an alert commitment until the 449th was inactivated in 1977. 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 4239th 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. 449th 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 4239th SW was replaced by the 449th Bombardment Wing, Heavy which assumed its mission, personnel, and equipment on 1 February 1963. In the same way the 716th Bombardment Squadron, one of the unit's World War II historical bomb squadrons, replaced the 93d BS. The 70th Munitions Maintenance Squadron was reassigned to the 449th. Under the Dual Deputate organization, all flying and maintenance squadrons were directly assigned to the wing, so no operational group was activated. The 4239th's maintenance and security squadrons were replaced by ones with the 449th numerical designation of the new wing. Each of the new units assumed the personnel, equipment, and mission of its predecessor. In July 1963, the wing added an air refueling capability when the 908th Air Refueling Squadron, equipped with Boeing KC-135 Stratotankers, was organized and assigned to the wing. The 449th continued the mission of strategic bombardment training and contributing to SAC's worldwide refueling capability. It supported SAC combat operations in Southeast Asia by furnishing KC-135 aircraft and crews from November 1965 through December 1975 and B-52 crews between May 1968 and June 1975. Although the number of ADC interceptor squadrons remained almost constant in the early 1960s, attrition (and the fact that production lines closed in 1961) caused a gradual drop in the number of planes assigned to fighter interceptor squadrons, from 24 to typically 18 by 1964 and to 12 by 1967. Because of this reduction, in December 1965, the Department of Defense announced it would close Kincheloe by
