History For a history prior to 1993, see Air Training Command On 1 January 1993, Air Training Command absorbed Air University and changed the command designation to Air Education and Training Command (AETC). AETC assumed responsibilities for both aspects of career development: training and education. Missions such as combat crew training, pararescue, and combat controller training, and (later) space training transferred to the new command, so that airmen would report to their operational units mission ready. Restructuring the command assumed priority among the issues facing the command staff. The introduction of three new training aircraft, the Raytheon T-1 Jayhawk, Slingsby T-3 Firefly, and Beech T-6 Texan II (JPATS); the addition of joint training; and the BRAC-mandated closures of Chanute AFB, Illinois (a major technical training center); Mather AFB, California (previously USAF's sole Undergraduate Navigator Training base) and Williams AFB, Arizona (an Undergraduate Pilot Training base) were major challenges following the establishment of AETC. In 1994, AETC adopted the Objective Wing Concept and stood up several wings responsible for crew training in the F-16, special operations aircraft, airlift aircraft, the KC-135 aerial refueling aircraft, and space and missile operations. AETC also began the first Specialized Undergraduate Pilot Training (SUPT) and Joint-SUPT courses. Lowry AFB, Colorado,
