The post Cold War environment brought many changes to Altus AFB. On 1 June 1992, the Air Force reorganized and the Military Airlift Command (MAC) disestablished. In its place the new Air Mobility Command (AMC) was activated, which placed MAC's strategic and tactical airlift aircraft and SAC's aerial refueling aircraft under a single command. Second, the 443d Airlift Wing and the 340th Air Refueling Wing were inactivated, with the latter's aircraft transferred to the 19th Air Refueling Wing (19 ARW) at Robins AFB, Georgia.
