Aircraft Background Edit
Before the 508 had made it’s first flight, the Admiralty were considering the greater power available from forthcoming jet engines. The speed of their future aircraft would not be limited by thrust, but by it’s aerodynamic design. Several months earlier, the 510 had been upgraded to naval requirements (Type 517) and landed on HMS Illustrious. Having confirmed the slow speed capability of the swept wing design, Supermarine thus proposed redesigning the 508 to include the swept wing of the 510.
The 525 was designed with the V tail, however structural problems identified in the 508 resulted in the 525 being modified to a cruciform tail before it’s first flight. When the 525 flew in April 1954, pitch instability was identified and the tail was further modified. It was expected to fly supersonic due to the increased engine thrust, but only managed mach 0.95 in level flight.
During a test flight in July 1955, the 525 entered a spin from which the pilot, Lt. Cdr. Rickell, could not recover. It was destroyed in the resulting crash, killing the pilot. It had only completed 61 hours of flying time, but had provided valuable data on the development of blown flaps.
A de-navalised version (removal of folding wings, arrestor gear) known as the type 526 was proposed to the RAF for specification F.3/48. This requirement was satisfied by the Swift.
