(CIGTF), the High Speed Test Track, the Radar Target Scatter Facility (RATSCAT), and the Target Drone Facility. These organizations were combined to form the nucleus of a Holloman AFB tenant organization, the 6585th Test Group, with the Air Force Special Weapons Center (AFSWC) at Kirtland Air Force Base, New Mexico, designated as the headquarters for the Test Group. In 1975, AFSWC was disestablished, and the 6585th Test Group at Holloman became part of the Armament Development and Test Center (ADTC) at Eglin AFB Florida. Tactical Training Center Holloman was designated a Tactical Training Center on 1 August 1977 and on 1 October 1993, the Air Force Development Test Center at Eglin AFB was redesignated as the Air Armament Center (AAC). In 1986, a contract was awarded to Flight Systems Inc. (later Honeywell) to modify 194 surplus Convair F-106 Delta Dart aircraft stored at Davis-Monthan AFB Arizona to the QF-106A target drone configuration. This program came to be known as Pacer Six, and the first flight of a converted drone took place in July 1987. Following the completion of an initial batch of ten QF-106s in 1990, most of the work was transferred to the USAF itself. Much of the conversion work was done before the aircraft were removed from storage at AMARC, with further work being carried out at East St Louis, Illinois. The QF-106s began operating as a Full-Scale Aerial Target (FSAT) in late 1991 at White Sands Missile Range New Mexico, and later at the Eglin Gulf Test Range in Florida (based at Holloman and Tyndall). A typical mission would employ the QF-106 as a target for an infrared homing missile. The aircraft had burners placed on pylons underneath the wings to act as IR sources for heat-seeking missiles. The intention of the program was for the QF-106 to survive repeated engagements with air-to-air missiles, to make it possible for each QF-106 to last as long as possible before it was destroyed. The last shootdown of a QF-106 (57–2524) took place at Holloman AFB on 20 February 1997. The QF-106 was replaced by the QF-4 Phantom drone. Today, the 96th Test Group from Eglin Air Force Base Florida is responsible for operational testing and evaluation of new equipment and systems proposed for use by these forces. Current initiatives include advanced self-protection systems for combat aircraft, aircrew life support systems, aerial reconnaissance improvements, new armament and weapons delivery systems,
