[4] On 1 September 1943, the 20th disbanded[2] and combined with support units at Houlton to form Station 3, North Atlantic Wing, Air Transport Command.

[2][6] The squadron's mission was to provide inter-theater and strategic airlift to Europe, North Africa and Canada.

The Starlifter brought a mission change to that of providing worldwide airlift, which included support of operations in Southeast Asia.

In December 1989, the squadron provided airlift support for Operation Just Cause, the replacement of Manuel Noriega as the ruler of Panama.

Two years later, the 20th relocated to Travis Air Force Base, California, where it was assigned to the 60th Operations Group as Travis's 60th Wing prepared to transition from an airlift to an air mobility wing the following year.
