Meteor F. Mk. I
GLOSTER METEOR - The Gloster Meteor was designed by a team led by George Carter during 1940 to take advantage of the still unproved Whittle turbojet, and Air Ministry Specification F.9/40 was written round the Gloster proposal for a single-seat twin-engined fighter armed with four 20 mm British Hispano cannon. Twelve prototypes ordered February 1941, of which only eight built, with various engines. First to fly, on March 5, 1943, was DG206, powered by 1,500 lb st (681 kgp) de Havilland H.ls, and with a wing span of 44 ft 3 in (13.49 m). Next to fly, on July 24, 1943, DG202 had 1,526 lb st (693 kgp) Rover W.2B engines and span of 43 ft 0 in (13.11 m); and a prototype with 2,000 lb st (908 kgp) Metrovick F.2 axial-flow turbo-jets, DG204, flew on November 13, 1943. One other prototype had H.I engines and pressure cabin; remainder powered by Rolls-Royce built engines of Whittle type.
Gloster Meteor F. Mk I: Initial production contract for 300 F.9/40-type fighters placed June 1941, to be named Gloster Meteor and powered by Rolls-Royce W.2B/23 engines named Welland. Twenty built to F Mk 1 standard with four 20 mm cannon; first flight January 12, 1944.
