Supermarine Type 528 Fighter Prototype

The Supermarine Type 528 was the second prototype designed by Supermarine against Specification E.1/46, as an experimental aircraft suitable for investigating the high subsonic regime. The design retained both the 5,100 lb Nene engine of the Vickers Supermarine Attacker, and its tailwheel undercarriage.

The second prototype (VV119) was first flown as the Supermarine Type 528 on 27th March 1950. Shortly afterward, the aircraft was modified further with a lengthened nose, engine reheat (afterburning) and tricycle undercarriage. With these changes it was redesignated as the Supermarine Type 535 Swift, making its maiden flight in August 1950.
