Fairchild C-123 Provider

The C-123 Provider was an American military transport aircraft designed by Chase Aircraft and subsequently built by Fairchild Aircraft for the United States Air Force. It went on to serve most notably with various armed forces in South East Asia.

Design and development

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. The only difference between the two was the engine. The XC-123 used two Pratt & Whitney R-2800-CB-15 air-cooled radial piston engines, while the XC-123A used two General Electric J47-GE-11 turbojets, the same as those on the Boeing B-47 Stratojet. It was initially well regarded for tactical troop transport for its ruggedness and reliability and ability to operate from short and unimproved airstrips, which meant the low slung turbojets, prone to ingesting foreign objects, were dropped in favor of the more conventional option. The XC-123A had its engines replaced with R-2800s and was redesignated YC-123D.

By 1953, Henry J. Kaiser purchased a majority share in Chase Aircraft, feeling that after having completed C-119s for Fairchild under contract, he could take control of the impending C-123 contract. Two airframes were completed at Kaiser's Willow Run factory in Ypsilanti, Michigan, before personal politics led to Kaiser's being told that no further contracts would be honored with him. The C-123 contract was put up for bid, and the two completed airframes scrapped. The contract was finally awarded to Fairchild Engine and Airplane, who assumed production of the former Chase C-123B, a refined version of the XC-123.
