The Speed Spitfire was a Supermarine Spitfire Mk I, re-engined and modified for an attempt on the world air speed record. It was already outdated when it first flew in 1938 and, despite repeated modification, never attained a competitive performance.
The Spitfire was also adopted for service on aircraft carriers of the Royal Navy; in this role they were renamed Supermarine Seafire. Although the first version of the Seafire, the Seafire Ib, was a straight adaptation of the Spitfire Vb, successive variants incorporated much needed strengthening of the basic structure of the airframe and ...

At the time the record of 352 mph (566 km/h) was held by Howard Hughes flying a Hughes H-1 racing aircraft. [nb 6] Although an early Spitfire I was capable of 362 mph (583 km/h), this was at a full-throttle height of 16,800 ft (5,100 m); the regulations for the world speed record demanded that the aircraft fly a 1.86-mile (2.99 km) course at an ...
