The end of the Cold War led to a downsizing of the military. The Base Realignment and Closure Commission of 1991 recommended closure of Grissom Air Force Base. On 1 February 1992, the Air Force Reserve redesignated the 434th Air Refueling Wing, Heavy, as the 434th Air Refueling Wing and that year activated the 74th Air Refueling Squadron within the 434th Air Refueling Wing to operate the KC-135 Stratotanker. The Air Force inactivated Strategic Air Command (SAC) and realigned the 305th Air Refueling Wing to the newly established Air Mobility Command (AMC) on 15 June 1992. The Air Mobility Command merged air refueling aircraft from Strategic Air Command with strategic airlift aircraft (e.g., C-5, C-141 and tactical theater airlift aircraft (e.g., C-130) from the concurrently disestablishing Military Airlift Command (MAC). The Air Force Reserve renamed the 434th Air Refueling Wing as the 434th Wing on 1 August 1992. Base Realignment and Closure Commission of 1993 directed realignment of Grissom Air Force Base to the Air Force Reserve (AFRES).
