The Hawker Sea Fury Carrier borne fighter-bomber was the British Fleet Air Arm's last piston-engined fighter, developed during WWII it did not see service with the Fleet Air Arm until after the war. It was arguably the fastest piston powered aircraft ever manufactured. It was a development from the Hawker Tempest, itself a development of the Hawker Typhoon. Originally, the Hawker Fury was designed by Sidney Camm in 1942 under F.2/43 specification, to provide the RAF with a lightweight replacement for the Tempest II. On 23 June, 1942, Luftwaffe Pilot Oberleurnant Arnim Faber erroneously landed his Focke-Wulf FW-190A-3 fighter at RAF Pembrey, apparently having mistaken this airfield for a Luftwaffe channel coast airfield. The British were thereby presented with a working example of the FW-190 fighter, which had been giving the RAF an extremely difficult time. The Hawker Fury design was a direct result of the examination of Faber's FW-190A-3. Examination of Faber's aircraft was largely responsible for the preparation of Specification F.6/42, which called for a new, high-performance fighter. The design was modified in 1943 to meet a Royal Navy specification (N.7/43) for a carrier-based interceptor and named the Hawker Sea Fury. Hawker was designated to work on the land-based version, and responsibility for the naval conversion was assigned to Boulton-Paul Aircraft Ltd. of Wolverhampton.
