Affectionately called Tiffy, British Royal Air Force (RAF) Hawker Typhoon ground-attack aircraft began as replacement design for high-altitude RAF Hawker Hurricane and Supermarine Spitfire fighters in 1939. Two prototypes were built, R-prototype with Rolls-Royce engine nicknamed the TORNADO, N-prototype with Sabre engine called the Typhoon, both in the 2,000 horsepower engine range.

R-prototype engine failed during development phase, while N-prototype lost engine power and maneuverability above 10,000 feet, thereby making the Typhoon useless as Spitfire and Hurricane fighter replacements. However, during 1942 Dieppe Raid, Typhoons were able to intercept low-level German aircrafts, thus was converted to ground-attack role. By end of war, circa 3,300 Typhoons were produced.
