The BAC Jet Provost is a British jet trainer aircraft that was in use with the Royal Air Force (RAF) from 1955 to 1993. It was originally developed by Hunting Percival from the earlier piston engine-powered Percival Provost basic trainer, and later produced by the British Aircraft Corporation (BAC). In addition to the multiple RAF orders, the Jet Provost, sometimes with light armament, was exported to many air forces worldwide. The design was also further developed into a more heavily armed ground attack variant under the name BAC Strikemaster.

The Jet Provost T5 was the final development of the first basic trainer in the world to go into service.

As military flying development in the 1960s, the increased emphasis given to work at high altitude placed a severe physiological strain on aircrew unless a pressurised cockpit was provided. In 1964 the original designers of the Jet Provost responded to the need for a pressurised version and began private work on the design. The Jet Provost T5 differed externally from earlier versions by a re-designed hood and a more bulbous shape to accommodate the pressurised cockpit.

The prototype T5 made its first flight on 28 February 1967. A total of 110 Jet Provost T5s were produced for the Royal Air Force and the first was handed over to the Central Flying School on 3 September 1969. Between 1973 and 1976, ninety-three were modified by an upgrade in avionics equipment and became T5As.
