Continuing the wartime development of the famous Supermarine Spitfire, the Mk.XIV saw the classic shape of Mitchell's celebrated fighter paired with the awesome power of the new Rolls Royce Griffon engine. The resultant aircraft was superb and one of the RAFs most capable fighters of WWII, proving particularly successful when employed against the V-1 flying bomb attacks which Germany launched against southern Britain, from the summer of 1944.
