The Jetstar is a distinctive four-engined executive jet which first flew in 1957. The first prototype used two Bristol Orpheous engines, but when the aircraft won a USAF contest for airways inspection/executive transport aircraft, the lack of a suitable US engine caused the type to be re-engined with four JT12 engines.

The Jetstar was the first dedicated business jet to enter service, and was also for many years the largest available. 16 examples entered USAF service, and 188 other examples were produced for other military and civil customers. A program to re-engine the aircraft with TFE731 turbofan engines enabled the aircraft’s service life to be considerably extended.
