As a result, the 4135th SW was replaced by the newly constituted 39th Bombardment Wing, Heavy (39th BW), which assumed its mission, personnel, and equipment on 1 February 1963. In the same way the 62d Bombardment Squadron, one of the unit's World War II historical bomb squadrons, replaced the 301st BS. The 54th Munitions Maintenance Squadron was also reassigned to the 39th. The 4135th's component maintenance and security units were replaced by units with the 39th 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. Each of the new units assumed the personnel, equipment, and mission of its predecessor. The 39th BW trained to maintain combat readiness for strategic bombardment on global scale, maintaining airborne alert, ground alert, and participated in numerous exercises. On 25 June 1965 The growing United States commitment to the Vietnam War meant funds were also needed to cover the costs of combat operations in Indochina and the 39th Bombardment Wing was inactivated on 25 June 1965. The wing's 62d BS was reassigned to the 2d Bombardment Wing at Barksdale AFB, Louisiana to support SAC Arc Light combat operations over Southeast Asia but its other components were discontinued. SAC's place at Eglin was taken by Tactical Air Command, which organized the 33d Tactical Fighter Wing, which took over the SAC facilities at the base. The 39th Bombardment Group was redesignated 39th Tactical Group and activated on 1 April 1966 at Incirlik Air Base, Turkey, and replaced the 7216th Combat Support Group to control permanent support units and deployed weapons training detachments. The redesignation was part of the USAFE takeover of the base and its support functions. Known as TUSLOG (The United States Logistics Group) Detachment 10 within Turkey until 1 October 1982, it supported the USAFE and NATO operational missions in the Middle East. It provided disaster relief and mercy missions as required during fires, floods, earthquakes, and other such disasters. The group provided support for US and NATO forces during operations in Southwest Asia, Eastern Europe, and Iraq, August 1990–present. On 31 January 1984, the group was consolidated with the 39th Bombardment Wing. The consolidated unit retained the designation of 39th Tactical Group. It was redesignated the 39th Wing and resumed wing status on 1 October 1993. Since then the unit has provided operational and logistical support for all U.S. forces in Turkey and operated a Supreme Allied Command Europe Quick Reaction Alert Force.
