Gloster F.9/37

Designed by W G Carter to meet the demands of Specification F.9/37 calling for a twin-engined single-seater, this Gloster fighter was of all-metal stressed skin construction. It was intended to carry a fuselage-mounted armament of two 20mm Hispano cannon and four 7.7mm Browning machine guns. Two prototypes were ordered, the first of these, powered by two 1050hp Bristol Taurus T-S(a) 14-cylinder radials, being flown on 3 April 1939. The aircraft attained a maximum speed of 579km/h at 4575m, but was badly damaged in a landing accident early in its flight test programme. When testing was resumed in April 1940, it had been re-engined with 900hp Taurus T-S(a) Ills with the result that performance suffered, maximum attainable speed in level flight being reduced to 534km/h at 4630m. The second prototype, meanwhile, had been completed with 885hp Rolls-Royce Peregrine liquid-cooled engines, flying for the first time on 22 February 1940, and attaining a maximum speed of 531km/h during subsequent flight testing. Although the handling characteristics of Gloster's F.9/37 contender were considered highly satisfactory and performance with the original engines had proved spectacular, no production was ordered.

The prototype performance figures indicated the potential for a very promising heavy fighter which with further development could have served throughout WW2.

Perhaps this plane did not "fit", but a plane of simlar design if not larger overall (and agreed slower) went on to some success in the shape of the Beaufighter. Just for the record it was only the earlier model Mosquitoes that had trouble with warmer climes, later models had the adhesive (or Pritt as noted elsewhere) changed and proved a lot more successful.

Ha ha, like that comment, Art Deco, or had no gun like the RAF version of the Eurofighter Typhoon, no doubt! I suppose it 'may' have meant the Mosquito would've been shelved, though that was more multi-role, or that the F-9 would've at least been overshadowed had the mossie entered service, still, it might not have broken up like the mossie in the far east, being metal and not stuck together with 'pritt'!

Definitely political. If it was fitted with a Boulton-Paul 4-gun turret instead of forward firing guns ( in the most unusual location ) it would have won contracts and priorities.

Appears to be yet another fine British design wasted. Why was not a production contract forthcoming - another instance of Ministry lack of foresight perhaps? The prototype performance figures indicated the potential for a very promising heavy fighter which with further development could have served throughout WW2.

Do you have any comments about this aircraft ?
