"Spitfire" is a song by the English electronic dance music group the Prodigy. It was initially released as a 12-inch vinyl record on 4 April 2005, as a digital download from iTunes the following day, and as a CD single on 11 April 2005.
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 It was already outdated when it first flew in 1938 and, despite repeated modification, never attained a competitive performance.
A top speed of 423 mph (681 km/h) at 18,500 ft (5,639 m) was predicted. However, constant problems with the development of the Griffon meant that the decision to proceed with building a Spitfire with this engine didn't come to fruition until 1942, with the successful flight trials of the Mk IV.
Also not formally accepted by the FAI, which was not present due to wartime conditions, are speeds recorded in a dive during high-speed tests with the Supermarine Spitfire, including Squadron Leader J.R. Tobin's 606 mph (975 km/h) in a 45° dive in a Mark XI Spitfire (date unknown) and Squadron Leader Anthony F. Martindale's breaking 620 mph ...
Also, in June 1938, the Heinkel He 100 V2 set a new record of 394.6 mph (635.0 km/h), which was very close to the maximum speed the as yet unflown Speed Spitfire was likely to achieve; the first flight of the modified Spitfire took place on 11 November 1938 and, in late February 1939, the maximum speed reached was 408 mph (657 km/h) at 3,000 ft ...

Depending on the supercharger fitted, engines were rated as low altitude (e.g.; Merlin 66, Griffon III), where the engine produced its maximum power below about 10,000 feet (3,000 m), medium altitude (Merlin 45), where the engine produced its maximum power up to about 20,000 feet (6,100 m), and high altitude (Merlin 70), where the engine produced its maximum power above about 25,000 feet ...
The maximum power of the Merlin 66 was 1,720 hp (1,280 kW) at 5,750 ft (1,283 kW at 1,752 m) and the maximum speed of the Spitfire LF Mk IX was 404 mph (650 km/h) at 21,000 feet (6,400 m). [34] The Merlin 66 introduced a new Bendix-Stromberg injection carburettor, which replaced the earlier S.U float carburettor.
