The Percival Prince is a British light transport of the early postwar period. It was a twin-engine, high-wing, cantilever monoplane of all-metal stressed-skin construction; the undercarriage was of retractable, tricycle type.


The design of the Prince continued from the solitary Merganser. Further development of the type led to the Survey Prince survey aircraft and the Sea Prince. An improved version of the Prince 3 with an increased wingspan and engine and undercarriage modifications was developed for the Royal Air Force as the Percival Pembroke.

Operational history[edit]

Percival Prince 3E executive aircraft of Standard Motor Co. at Croydon Airport in April 1954

The Prince was produced in six versions for the civil market. Several examples were operated as executive aircraft including by Standard Motors and Shell Oil. Three aircraft were used by the UK Ministry of Civil Aviation as airport facilities checking aircraft.

The Sea Prince operated in two roles: in T.Mk.1 form it served as a navigation and anti-submarine trainer; the C.Mks. 1 and 2 were flown in the transport role. However, these were landplanes and not COD (carrier on-board delivery) aircraft. Sea Princes operated in both roles from 1954 to 1972 and as a navigation trainer until 1978, when it was replaced by the Handley Page Jetstream
