The Supermarine Seafang was a British Rolls-Royce Griffon–engined fighter aircraft designed by Supermarine to Air Ministry specification N.5/45. It was a further development of Supermarine's famous Spitfire and Spiteful aircraft, becoming "a Spitfire too far".〔Price, 2001〕 ==Design and development== The Seafang was essentially a Spiteful redesigned for Royal Navy carrier use, with the addition of an arrester hook, a contra-rotating propeller to eliminate engine torque effects, and power folding outer wing panels. Two prototype Type 396 Seafang Mark 32s were ordered on 12 March 1945 followed by an order for 150 Type 382 Seafang Mark 31s on 7 May 1945.〔 To expedite entry into service the interim Mark 31 was ordered which was a navalised Spiteful, basically a Spiteful with an arrestor hook. This would allow the Mark 32 to be developed; it would be the definitive naval variant, again with an arrestor hook but also folding outer wing panels and a contra-rotating propeller. The first Seafang flew in 1946; it was the first interim production Mark 31 ''VG471''. Although 150 of the interim variant were ordered, only nine were completed before the order was cancelled as the urgency of an interim type was removed due to the end of the war. The first prototype definitive Mark 32 ''VB895'' was first flown in June 1946. It was powered by a Griffon 89 engine rated at 2,350 hp (1,752 kW) driving two three-bladed contra-rotating propellers. In August 1946, ''VB895'' was demonstrated to the Royal Netherlands Navy at Valkenburg.〔 The same aircraft was flown by noted test pilot Mike Lithgow in May 1947, during deck landing trials on .〔 Compared to the Seafire F.47, its performance advantage was not deemed to be enough to disrupt series production of new navalised Meteor and Vampire jet fighters. Also, the Seafang's low-speed handling characteristics were not as good as hoped, and the contemporary Hawker Sea Fury was preferred as a fleet fighter. Seafang Mark 31 ''VG474'' was used as a development aircraft for the Supermarine Attacker including the fitment of power-operated ailerons〔 and contra-rotating propellers.〔 The Attacker was a jet-powered development of the Spiteful/Seafang design which used the Spiteful laminar-flow wing and landing gear.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Supermarine Seafang」の詳細全文を読む スポンサード リンク
