Supermarine was the third aero-concern to offer its proposal - the Type 508 - to the British Air Ministry's F.43/46 (Operational Requirement 228) seeking to satisfy a Day Fighter requirement for the Royal Air Force (RAF). The Type 508 followed the Gloster P.234 and the Hawker P.1054 / P.1061 proposals (both detailed elsewhere on the Military Factory) of which none were formally selected outright. The Hawker designs, however, went down an evolutionary road to begat the "P.1067" which, in turn, became the classic swept-wing, jet-powered Hawker Hunter jet-powered fighter of the early Cold War period for Britain and led a healthy and long operational service life from there.

For Supermarine's part in the project, the company simply worked off of its naval-minded Type 508 which flew for the first time, in prototype form, on August 8th, 1951. The original, relatively oversized fighter aircraft had side-mounted intakes, straight mainplanes, and "V-type" tail unit with outward-canted planes. Planned armament was 4 x 30mm Aden automatic cannons and power would come from a pair of Rolls-Royce Avon RA.3 turbojet engines of 6,500lb thrust each.

At any rate, the Type 508 in its navalized form never materialized beyond prototypes but was resurrected for the RAF requirement. One of the primary requirements of the new fighter would be carrying a massive, still in-development, 4.5" automatic cannon in the fuselage with seven proximity-based rounds afforded to it. The Rolls-Royce AJ.65 or the competing Metrovick F.9 turbojets were the preliminary powerplant and this would appear in paired form for maximum power and performance at the expense of fuel burn. Maximum speed of the resulting aircraft would be in the 580 miles-per-hour range with an operating ceiling of around 45,000 feet.

Unlike the original straight-wing-only Type 508 aircraft, the revised version being offered was displayed in both a straight-wing and swept-wing forms to satisfy the Air Ministry on both fronts. The straight-winged model would be a fail-safe design against the more advanced, though still untested, swept-wing model. As such, the straight-wing design could, at some future time, be converted to swept-wing form as technology and research allowed. Similarly, the intended 4.5" autocannon could someday be revised to a 4 x 30mm cannon battery as needed by the service.

Like its navalized Type 508, the revised Type 508 was not furthered.©MilitaryFactory.com
