Spitfire, also called Supermarine Spitfire, the most widely produced and strategically important British single-seat fighter of World War II. The Spitfire, renowned for winning victory laurels in the Battle of Britain (1940–41) along with the Hawker Hurricane, served in every theatre of the war and was produced in more variants than any other British aircraft.

In late 1943 Spitfires powered by Rolls-Royce Griffon engines developing as much as 2,050 horsepower began entering service. Capable of top speeds of 440 miles (710 km) per hour and ceilings of 40,000 feet (12,200 metres), these were used to shoot down V-1 “buzz bombs.” During World War II, Spitfires were exported in small numbers to Portugal, Turkey, and the Soviet Union, and they were flown by the U.S. Army Air Forces in Europe. When production ceased in 1947, 20,334 Spitfires of all versions had been produced, 2,053 of them Griffon-powered versions. Fighter versions of the Spitfire were dropped from RAF service during the early 1950s, while photo-reconnaissance Spitfires continued in service until 1954.
