The Supermarine Spitfire was a single seat fighter plane that was used by the Royal Air Force of Great Britain and other Allied forces during World War II. The Spitfire was by far the most produced British fighter plane produced for the war. It was designed to be a short range, high speed aircraft with excellent maneuverability. The Spitfire became an iconic plane due to its important role in winning the Battle of Britain, in which the entire Royal Air Force took to the air to counter a Nazi bombing campaign. After winning the battle, the Spitfire became the backbone of the Royal Air Force.
