Vickers Type 559

The Vickers Type 559 was a supersonic interceptor aircraft design by the British aircraft company Vickers-Armstrongs and was their submission for Operational Requirement F.155 in 1955.

Type 559
Role Interceptor
Manufacturer Vickers-Armstrongs
Number built None

It was not accepted for further consideration; the most valued submissions being from Armstrong Whitworth and Fairey, however the F.155 requirement was dropped as a result of the 1957 Defence White Paper.[1]

Design and development

The Type 559 was an unorthodox canard design with a massive chin air intake, split vertically, for two reheated de Havilland Gyron engines of 20,000 pounds-force (89 kN) thrust each, placed as in the English Electric Lightning, one above the other. Two de Havilland Spectre Junior rockets were situated each side of the fuselage at wing level. Two Red Hebe or Blue Jay missiles were mounted alongside the upper part of the fuselage between the canard and the mainplane, which had endplates incorporating twin rudders.
