The 1700th Air Transport Group is a discontinued United States Air Force unit. It was last assigned to the 1700th Air Transport Wing at Kelly Air Force Base, Texas, where it was inactivated on 18 December 1957. The group was organized in June 1948 from the resources of a provisional unit that had been established by Air Transport Command at Kelly the previous year. Shortly after organizing, the 1700th transferred many of its Douglas C-54 Skymasters to Germany, where they served in the Berlin Airlift. It provided strategic airlift until it was discontinued as Military Air Transport Service concentrated its operations at locations on the Atlantic and Pacific coasts.
On 12 June 1947, Air Transport Command (ATC) organized the 5th Air Transport Group (Provisional) at Kelly Field, Texas and assigned four provisional air transport squadrons. the 33rd, 34th, 51st and 52nd to the group. The group's squadrons were equipped with Douglas C-54 Skymaster four-engine transports. The provisional group was located with Air Materiel Command's large aircraft depot maintenance and supply facilities at Kelly. The group and squadrons continued in provisional status until 1 June 1948, when ATC and Naval Air Transport Service were combined into Military Air Transport Service (MATS).
History

The group was organized as the 518th Air Transport Group on 1 July 1948, as MATS replaced ATC. It was assigned to the 518th Air Transport Wing and its 8th, 9th and 10th Air Transport Squadrons took over the personnel and equipment of the provisional squadrons, which were discontinued, along with the provisional 5th Group.[b] However, shortly after the group was organized, two of its squadrons deployed to Germany to augment the Berlin Airlift. As a result, on 1 July, the 518th Wing was discontinued and the group was assigned directly to Continental Division, Military Air Transport Service.
In the summer of 1948, Headquarters USAF allotted blocks of numbers to its subordinate commands to use for the units they organized. On 1 October 1948 MATS renumbered its air transport squadrons between 1250 and 1299, and its other units assigned to Continental Division starting with the number 1700. Simultaneously, it redesignated the group as the 1700th Air Transport Group and organized the 1700th Air Transport Wing and other support units, while transferring the 10th Air Transport Squadron, which had an aeromedical evacuation mission to the 1702nd Air Transport Group.

In 1952, MATS received permission to replace its Major command controlled air transport squadrons with World War II ferrying and transport squadrons. As a result, the group's flying squadrons were all replaced. The 55th Air Transport Squadron, assumed the assets of 1262d, the 56th Air Transport Squadron, assumed the assets of the 1275th, the 57th Air Transport Squadron assumed the assets of the 1256th, the 58th Air Transport Squadron, assumed the assets of 1286th, and the 76th Air Transport Squadron, assumed the assets of the 1289th. Shortly before this, on 7 March the group had exchanged squadron numbers with the 1705th Air Transport Group at McChord Air Force Base, Washington, with the 1280th and 1291st Squadrons being replaced by the 1286th and 1289th Squadrons.
The group provided worldwide transport of supplies and equipment to all parts of the world. It operated C-54s, Boeing C-97 Stratofreighters and primarily C-124 Globemaster II transports, frequently forming transport squadrons then once trained and equipped would reassign them to new MATS organizations. During the 1950s, the 1700th operated MATS transport aircraft as well as passenger aircraft.
However, during the 1950s, MATS was realigning its organization to focus on overseas transport. In October 1953, the 55th Air Transport Squadron moved to Travis Air Force Base, California, followed by the 56th in March 1954. The 58th Air Transport Squadron moved to McGuire Air Force Base, New Jersey in June 1955. When Continental Division reduced its operations at Brookley Air Force Base, Alabama, the 3d Air Transport Squadron was briefly assigned in 1957 before moving to Charleston Air Force Base, South Carolina, [1]
In 1957 MATS inactivated its Continental Division, along with the 1700th Group.[2]
