1600th Air Transport Group

The group was formed from the personnel and equipment of the 1st Air Transport Group (Provisional), a C-54 Skymaster unit of Air Transport Command (ATC) at Westover when Military Air Transport Service (MATS) replaced ATC in 1948. The 1st had been organized as the operational element of the 2d Air Transport Wing (Provisional) Under the experimental wing base (Hobson Plan) organization system. When the 1600th was organized it became the operational element of the 520th Air Transport Wing (later the 1600th Air Transport Wing).

The group became Atlantic Division, Military Air Transport Service's primary strategic transport airlift provider between the United States and Europe in the late 1940s and early 1950s. In 1953, the group was transferred to the direct control of the Atlantic Division took as the wing was reduced to control of support elements in 1953 in anticipation of transfer of Westover from MATS to Strategic Air Command (SAC). The unit operated large numbers of Douglas C-124 Globemaster II heavy transports, as well as Boeing C-97 Stratofreighters. It provided passenger service on Navy Douglas R6D-1 Liftmasters and supported VIP transportation for Atlantic Division Headquarters at Westover. In the summer of 1948, the group's 16th Air Transport Squadron was reassigned directly to the Atlantic Division and in the fall it became part of Continental Division, MATS and moved to Gravelly Point, Virginia where it became a forerunner of the 89th Airlift Wing.

In July 1952, MATS replaced its table of distribution (four digit) air transport squadrons, which were controlled by the command with table of organization units whose organization was controlled by Headquarters, United States Air Force (USAF). The USAF controlled units were ferrying and transport squadrons that had been assigned to ATC during World War II. Unlike the MATS controlled squadrons that had been formed in peacetime, these units had histories that included wartime actions and could be continued even after inactivation.[1] Each of the new squadrons assumed the mission, personnel, and equipment of the squadron it replaced.

The group was inactivated in 1955 when MATS moved its Atlantic Division headquarters and airlift operations to McGuire AFB, New Jersey and SAC assumed control of Westover AFB.
