On 1 July 1993, the Air Training Command (ATC) was redesignated the Air Education and Training Command (AETC) and the command reactivated Second Air Force (2nd AF), stationing it at Keesler. Second Air Force's mission is to oversee all technical training conducted within AETC. The same day, Keesler Training Center was inactivated, and the 81st Training Wing arrived at the base. The 45th Airlift Squadron (45 AS), part of the 314th Airlift Wing at Little Rock AFB, Arkansas, was also located at Keesler. The 45th AS provided flight crew training in the C-21 Learjet until 2007, when it moved to Scott AFB.
