### Airlift training

In 1966, Military Air Transport Service (MATS) became Military Airlift Command and replaced its former Major Command Controlled (MAJCON or 4 digit) units with AFCON units. As part of this transformation, the 56th replaced the 1740th Air Transport Squadron at Tinker Air Force Base, Oklahoma in January 1966. The 1740th had been organized by MATS on 5 September 1951 as the 1740th Air Transport Squadron (Transition Training Unit) at McChord Air Force Base and was assigned to the 1705th Air Transport Wing. It moved to Palm Beach Air Force Base in July 1952 and to Tinker Air Force Base in March 1959 when MATS moved its training wing. At Tinker, the squadron provided training for aircrews in Douglas C-124 Globemaster II.

In January 1966, the 56th Military Airlift Squadron replaced the 1740th and continued to train Globemaster crews through 1968. With the arrival of the Air Force's first C-5 Galaxy on 17 December 1969, the 56th became the first operational C-5 squadron in the Air Force. It provided training and transition-flying training for aircrews in C-5 aircraft from 1969 to 2007. It also supported U.S. forces in Southeast Asia from April 1972 to December 1974.
The Squadron was re-designated as the 56th Airlift Squadron on 27 August 1991, becoming attached to the 97th Operations Group at Altus Air Force Base, Oklahoma. It operated Lockheed C-5 Galaxy aircraft, conducting initial and advanced aircrew training for airlift, airdrop and air refueling operations .
