North American Sabreliner

The North American Sabreliner, later sold as the Rockwell Sabreliner, is a mid-sized business jet developed by North American Aviation. It was offered to the U.S. Air Force in response to their Utility Trainer Experimental (UTX) program. It was named "Sabreliner" due to the similarity of the wing and tail to North American's F-86 Sabre jet fighter." Military variants, designated T-39 Sabreliner, were used by the U.S Air Force, U.S. Navy and U.S. Marine Corps after the Air Force placed an initial order in 1959. The Sabreliner was also developed into a commercial variant.

Design and development

North American began development of the Sabreliner as an in-house project, and in response to the UTX request for proposals, they offered a military version to the Air Force. UTX combined two different roles, personnel transport and combat readiness training, into the same aircraft.

The civilian version prototype, which carried the model number NA-265, made its first flight on September 16, 1958. It was powered by a pair of General Electric YJ85 turbojet engines. The type received its FAA type certification in April 1963. The UTX candidate, designated the T-39A, was identical in configuration to the NA-265, but when the contract was awarded and the T-39A entered production, it was powered with two Pratt & Whitney JT12A-8 turbojet engines.
