Supermarine 510 / 517 / 528 / 535
During 1946, in response to a contract to build two prototypes of a single-seat high-speed fighter to Specification E.41/46, Supermarine combined sweptback wing and tail surfaces with what was essentially an Attacker fuselage to create the Type 510. This retained the Rolls-Royce Nene 2 engine and tailwheel undercarriage of the Attacker.
The first prototype was flown on 29 December 1948. No armament was fitted, but provision was made for four wing-mounted 20mm cannon. The second prototype, designated Type 528, flew in similar configuration on 27 March 1950, and, on 8 November of that year, the Type 510, fitted with an Attacker-style A-frame arrester hook, made a series of landings and take-offs from the carrier HMS Illustrious.
Later, the first aircraft (now redesignated Type 517) was fitted with a movable rear fuselage permitting the incidence of the integral tailplane to be varied. Meanwhile, the Type 528 was fitted with an afterburning version of the Nene, a lengthened nose and a tricycle undercarriage as the Type 535, flying in this form for the first time on 23 August 1950, and providing the basis for the development of the Swift. Four wing cannon were carried by the 535, but such positioning found no official favour.
The Type 535 proved sufficiently impressive for a 100-aircraft order to be planned if the same company’s Type 541 proved a failure.
