The XG-20 did not see production due to a change in USAF requirements, however, it was modified into the successful Fairchild C-123 Provider twin-engined transport aircraft which saw extensive service in the Vietnam War.
The C-123 Provider was designed originally as an assault glider aircraft for the United States Air Force (USAF) by Chase Aircraft as the XCG-20 (Chase designation MS-8 Avitruc) Two powered variants of the XCG-20 were developed during the early 1950s, as the XC-123 and XC-123A.

Meanwhile, the second prototype XG-20 was returned to Chase Aircraft, to be fitted with two twin pods for General Electric J47 turbojets, becoming the XC-123A, the first jet-powered transport aircraft built in the United States.
In the late 1940s, Chase Aircraft had developed the XG-20, the largest glider ever built in the United States.

The Chase XCG-20, also known as the XG-20 and by the company designation MS-8 Avitruc, was a large assault glider developed immediately after World War II by the Chase Aircraft Company for the United States Air Force, and was the largest glider ever built in the United States.
Meanwhile, a third, still larger, assault glider had been designed by Stroukoff, the XG-20, the largest glider ever built in the United States and also the last combat glider to be constructed for the U.S. military.

Michael Stroukoff

His first design was the XCG-14, a wooden troop-carrying assault glider, which was developed into the larger CG-18 and CG-20 gliders, the latter being the largest glider ever constructed in the United States.
