Seafang F Mk 32

Development of a navalised Spiteful was pursued during 1945 to Specification N.5/45, and a contract was placed for two prototypes and 150 series aircraft, the name Seafang being assigned. A Spiteful F Mk 15 with a "sting"-type arrester hook was tested early in 1945, and the Seafang prototypes flew in the following year. One of these represented the production Seafang F Mk 31 with Griffon 61 engine and a long-stroke undercarriage, but non-folding wings. The othet represented the Seafang F Mk 32 with a Griffon 89 engine with contraprop, and upward-folding wings. Armament comprised four 20mm cannon and provision was made for carrying a pair of 454kg bombs or six 136kg rockets. After completion during 1946-47 of 10 Mk 31s and six Mk 32s (some of which were never flown) production was cancelled.

I do not think that any PROPELLER PISTON engine driven aircraft would go any faster than 550 MPH due to the fact of the propellers compressibility. As far as the wing shape was concerned the MITCHELL wing was a "nightmare" to build & repair.

nice, fast plane. perhaps if they had looked into the Spiteful and the Seafang a bit more they might have got them both into service and then pushed them to their limits. perhaps they might have been able to get them to go over 600mph like they did with a Spitfire; the planes was the right shape. i think they could have added jets to all the ww2 era Supermarine aircraft somehow

Lovely plane, once they solved the aileron control rod jamming issue. Of course, while faster in level flight than any Spitfire mark, its critical mach number was lower. Mitchell really did pick a winner of a wing initially. Perhaps they would have done better to keep the thickness ratios and semi-elliptical plan form of the Mitchell wing while going with a laminar flow cross section. In any event.. beautiful!

The jet age made them obsolete, the landplane version Spiteful F16 was most likely the fastest British piston engined fighter, one obtained 494mph on a Griffon 101 with a two speed & three stage supercharger. No examples exist today

What a sleek and beautiful machine. Faster than the Sea Fury (just) and thats very fast. Maybe the nicest looking propreller driven military aircraft ever? Are there any examples of this aircraft in museums around the globe?

Do you have any comments about this aircraft ?
