The Supermarine Stranraer was a twin-engine biplane - flying boat of the British manufacturer Supermarine Aviation Works . The 57 built machines were mainly used as escort aircraft for ship convoys in maritime reconnaissance and anti-submarine combat during the Second World War . The Stranraer was the last biplane flying boat of the Royal Air Force (RAF).
The type was designed according to the Air Ministry specification R.24 / 31 and had its first flight on July 27, 1934. The RAF put the Stranraer into service on April 16, 1937.
The structure was mostly made of duralumin , the fuselage shell made of sheet metal and the wings were covered with fabric. A gun turret was installed in the stern. The machine had two radial engines Bristol Pegasus X with 920 HP (685 kW).
