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."[1]

[edit] Design and development
The Type 383 Seafang was essentially a Spiteful redesigned for Royal Navy carrier use, with the addition of an arrestor hook and with a contra-rotating propeller to eliminate engine torque effects. The F.32 had folding wings, increased fuel capacity, and a Griffon 89 engine rated at 2,350 hp driving two three-bladed contrarotating propellers. Two aircraft of this type were completed, VB893 and VB895, although there is no evidence as to whether either actually flew before the end of hostilities.
[edit] Testing and evaluation
The Seafang first flew in 1946. Production of this aircraft never commenced but, in all, 18 prototypes and test machines were built, but some were never flown. Seafang FR.32 VB895 was flown by noted test pilot Mike Lithgow in May 1947 during deck landing trials on HMS Illustrious. 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 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.
During testing, it was claimed Seafang achieved a speed of 494 mph, making it, if the claim is valid, the fastest propeller driven aircraft ever built in the UK. Another distinction of the Seafang has is that its wing was adopted for later Supermarine Attacker jet fighter.
