Fairchild C-123K "Provider" - Castle Air Museum

The Fairchild C-123 Provider is an American military transport aircraft designed by Chase Aircraft and built by Fairchild Aircraft for the U.S. Air Force. In addition to its USAF service, which included later service with the Air Force Reserve and the Air National Guard, it went on to serve the U.S. Coast Guard and various air forces in Southeast Asia. During the War in Vietnam, the C-123 was used to deliver supplies, to evacuate the wounded, for agent insertions behind enemy lines, and was also used to spray Agent Orange.

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 was the class of engines used. The XC-123 used two Pratt & Whitney R-2800-23 air-cooled radial piston engines, while the XC-123A was fitted with four General Electric J47-GE-11 turbojets, in two pods. The XC-123A also has the distinction, while being experimental, of being the first USAF's jet-powered military transport. While the piston-powered XC-123 was initially well-regarded for its ruggedness, reliability, and its ability to operate from short and unimproved airstrips, the turbojet-powered XC-123A – designed for high-speed transport between USAF bases for critical parts and personnel – was found unable to operate from short and rough airstrips. There was also no practical speed advantage due to the wing and fuselage design, and a drastic reduction in range. Only the one turbojet-powered test and evaluation version was built.

While the United States Air Force was interested in placing an order for the new transport, Chase did not have the production capacity to meet the Air Force's needs, and sought a partner to handle production of the new aircraft.[5] 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 a pricing scandal that led to Kaiser's being told that no further contracts with him would be honored. 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.[6] Before turning production over to Fairchild, Chase originally named their C-123B the AVITRUC but it never stuck.

More About Castle Air Museum:
Castle Air Museum affords visitors from the region and throughout the world the opportunity to learn the costly sacrifices of the men and women who designed, built, maintained and flew these aircraft into hostile skies to defend freedom and liberty with many making the ultimate sacrifice. The Museum also serves to educate on the past milestones in aviation and what the future of aerospace may hold in store.

Castle Air Museum, located in the heart of California’s San Joaquin Valley is the largest aviation museum between Southern California and the State of Washington with over seventy restored vintage military aircraft on static exhibit with more to arrive in the future! The Museum is adjacent to the former Castle Air Force Base, now Castle Airport, and officially opened to the public in 1981 as a non-profit 501c3 organization with a mission “to preserve military aviation heritage for future generations.” Today the Museum has evolved into a premier showcase for families, history buffs, schools, tourists, and aviation enthusiasts.
