The Fairchild C-123 Provider is an American military transport aircraft designed by Chase Aircraft and subsequently built by Fairchild Aircraft for the USAF. The C-123 Provider was designed originally as an assault glider aircraft. Two powered variants of the Provider (XCG-20) were developed during the early 1950s. 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. While the piston-powered XC-123 was initially well regarded for tactical transport for its ruggedness and reliability and ability to operate from short and unimproved airstrips, the turbojet-powered XC-123A was found unable to operate from short and rough airstrips. The contract was finally awarded to Fairchild Engine and Airplane, who assumed production of the former Chase, a refined version of the C-123.

 

Die Fairchild C-123 Provider ist ein amerikanisches Militärtransportflugzeug, das von Chase Aircraft entworfen und später von Fairchild Aircraft für die USAF gebaut wurde. Die C-123 Provider wurde ursprünglich als Lastensegler entwickelt. Zwei motorisierte Varianten der Providers (XCG-20) wurden in den frühen 1950er Jahren entwickelt. Die XC-123 verwendete zwei luftgekühlte Sternmotoren Pratt & Whitney R-2800-23, während die XC-123A mit vier General Electric J47-GE-11 Turbojets in zwei Pods ausgestattet war. Während der kolbenbetriebene XC-123 anfänglich für taktische Transporte wegen seiner Robustheit und Zuverlässigkeit und der Fähigkeit, von kurzen und improvisierten Landebahnen aus zu operieren, geschätzt wurde, war die mit dem Turbojet betriebene XC-123A nicht in der Lage, auf kurzen und unebenen Landepisten zu operieren. Der Vertrag wurde schließlich an Fairchild Engine und Airplane vergeben, die die Produktion der früheren Chase, einer verfeinerten Version der C-123, annahmen.
