Tempest Vģd model Hawker Tempest Mk VThe prototype Hawker Tempest Mk V with the Sabre II engine was the first to be completed and looked very similar to the Typhoon. The Mk I (HM599) was powered by a Sabre IV, the Mk II (LA602 and LA607) by a Centaurus IV radial engine, while the Mk III (LA610) used a Griffon IIB, the Mk IV (LA614) a Griffon 61 and the Mk V (HM595) the Sabre II.

By this time the RAF had also changed the original contract for the prototypes and now wanted a total of six aircraft.ĭifferent serial numbers were assigned to each of the six prototype/engine combinations.
After the experience with the Typhoon and Tornado, and as a precautionary measure, the prototypes should allow the installation of alternative engines.īy the spring of 1942, the various problems with the Sabre engine had still not been completely solved and the company therefore continued its plans to be able to install alternative engines in the prototypes of the Typhoon II.ĭuring August 1942, the name of the new fighter was changed to Hawker Tempest due to the numerous substantial modifications.
Similar to the design for the de Havilland Mosquito, it was assumed that these coolers would reduce aerodynamic drag by almost two-thirds.īut the biggest problem Hawker had with the new fighter was the engine. In a separate design study Camm had developed a pair of wing radiators for the leading edges of the wings to replace the obstructive front radiator of the Typhoon. The Royal Air Force ordered two prototypes under the specification F.10/41 in November 1941 and the project was quickly named Typhoon II. This space was used for a 90 gal (345 litre) tank, so there were no more tanks in the now thinner wings. The airframe was modified with a 56 cm long extension between the engine mount and the cockpit. To save development time, Sidney Camm decided to assemble the new wings with a modified Typhoon airframe, which still used the Sabre engine.
