Percival Provost

1st Flight 1950

The Percival P.56 Provost is a basic trainer aircraft.

The Provost entered service with the RAF during 1953 and quickly proved to be more capable than the preceding Prentice.

It was a relatively successful aircraft, being exported for multiple overseas operators.

Various models were developed, both armed and unarmed, to meet with customer demands.

The Provost later adapted to make use of a turbojet engine, producing the BAC Jet Provost.

During the 1960s, the type was withdrawn from RAF service in favour of its jet-powered successor.

It continued to be used for decades with various export customers.
