The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and other Allied countries before, during, and after World War II. No. 243 Squadron was a flying squadron of the Royal Air Force. Originally formed in August 1918 from two flights that had been part of the Royal Naval Air Service, the squadron conducted anti-submarine patrols during the final stages of World War I. The squadron was later re-raised during World War II, operating initially as a fighter squadron in Malaya and Singapore during 1941–42. It was briefly disbanded just prior to the fall of Singapore, and was re-formed in mid-1942, again as a fighter squadron, and fought in the Tunisian and Italian campaigns in 1942–44, before being disbanded in October 1944. In 1945, after training on transport aircraft in Canada, the squadron moved to Australia where it operated in support of the British Pacific Fleet before disbanding in mid-1946 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.Brown timber frame with white mount containing photograph of fighter plane in sky.Spitfire by Barrie Clark Vickers Supermarine Spitfire Mk VB of 243 Squadron Royal Air Force 243 squadron royal air force, spitfire
