The Gloster Meteor was the first British jet fighter and the Allies’ only jet aircraft to engage in combat operations during the Second World War. The Meteor’s development was heavily reliant on its ground-breaking turbojet engines, pioneered by Frank Whittle and his company, Power Jets Ltd. Development of the aircraft began in 1940, although work on the engines had been under way since 1936.
The Meteor first flew in 1943 and commenced operations on 27 July 1944 with No. 616 Squadron RAF. The Meteor was not a sophisticated aircraft in its aerodynamics, but proved to be a successful combat fighter. Gloster’s 1946 civil Meteor F.4 demonstrator G-AIDC was the first civilian-registered jet aircraft in the world. Several major variants of the Meteor incorporated technological advances during the 1940s and 1950s. Thousands of Meteors were built to fly with the RAF and other air forces and remained in use for several decades.
To replace the increasingly obsolete de Havilland Mosquito as a night fighter, the Meteor was adapted to serve in the role as an interim aircraft. Gloster had initially proposed a night fighter design to meet the Air Ministry specification for the Mosquito replacement, based on the two seater trainer variant of the Meteor, with the pilot in the front seat and the navigator in the rear.
Once accepted however, work on the project was swiftly transferred to Armstrong Whitworth to perform both the detailed design process and production of the type; the first prototype flew on 31 May 1950. Although based on the T.7 twin seater, it used the fuselage and tail of the F.8, and the longer wings of the F.3. An extended nose contained the AI Mk 10 (the 1940s Westinghouse SCR-720) Air Intercept radar.
As a consequence the 20 mm cannons were moved into the wings, outboard of the engines. A ventral fuel tank and wing mounted drop tanks completed the Armstrong Whitworth Meteor NF.11.
