B.A.C. Jet Provost T Mk 3A Specifications
GENERAL DESCRIPTION
Our BAC Jet Provost is 1 of 70 single-engine low wing British basic training aircrafts 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.
