facility, Z-129 operated several unmanned gap filler sites: Winter Garden, Florida (M-129A): Inverness, Florida (M-129B): In 1966, the AN/FPS-26 was modified into an AN/FSS-7 submarine-launched ballistic missile detection and warning radar, part of the 14th Missile Warning Squadron. Around 1966, Site Z-129 became a joint-use facility with the Federal Aviation Administration and the search radar was modified to an AN/FPS-7E model. In 1968, ADC was redesignated as Aerospace Defense Command (ADC). In 1979, Site Z-129 came under Tactical Air Command (TAC) jurisdiction with the inactivation of ADC and the activation of Air Defense, Tactical Air Command, which was inactivated on 15 November 1980 and subsumed within TAC. The FSS-7 (the final such system in the USAF inventory) remained in use for about a year after the host 660th Radar Squadron inactivated and was reassigned as Det 1, 20th Missile Warning Squadron. The ground-to-air transmitter/receiver site was retained until the Joint Surveillance System switch-over circa 1984, with the radios being maintained by the 1928th Communications Squadron of the Air Force Communications Command. Tactical Air Command The first attempt to close MacDill AFB was made in 1960, when the impending phaseout of SAC's B-47 bombers caused it to be listed as surplus and slated for closure. However, the Cuban Missile Crisis of 1962 highlighted the base's strategic location and its usefulness as a staging area. As a result, the cuts were stayed and the base repurposed for a tactical mission with fighter aircraft. In response to the crisis, the United States Strike Command was also established at MacDill as a crisis response force; it was one of the first unified commands, a command that draws manpower and equipment from all branches of the U.S. military. In 1962, MacDill AFB was transferred from SAC to TAC. Bomber aircraft remained home-based at MacDill until the 306th Bombardment Wing's transfer to McCoy AFB, and SAC continued to maintain a tenant presence at MacDill through the 1980s, using their alert facility as a dispersal location for B-52 and KC-135 aircraft. But for all practical purposes, the 1960s marked MacDill's transition from a bomber-centric SAC base to a fighter-centric TAC installation. Under TAC, MacDill AFB remained a fighter base for almost 30 years, but other changes went on in the background. 12th Tactical Fighter Wing Upon MacDill AFB's transfer to TAC, the 12th Tactical Fighter Wing (12t TFW) was reactivated on 17 April 1962 and assigned to
