North American Mustang

Originally designed for the British Royal Air Force, the Mustang went on to serve with distinction in both the RAF and the USAAF.

Built for the Royal Air Force during World War 2. The spitfire is iconic and is a symbol of British defiance to the Germans during the war.

Crewed by pilots from the RAF, the commonwealth and nations occupied by the Third Reich - the Spitfire also became a symbol of freedom against oppression.

During the early stages of American involvement in the war, the USAAF units based in Britain were lacking a decent fighter that could compete with the Luftwaffa, so they used the Spitfire.

Power Plant:
Rolls Royce Merlin / Griffon
Operators: United Kingdom
United States
Supermarine Spitfire
Supermarine Seafire (Marine)
Armament: 4 x Browning M1919 .303
4 x Hispano Suiza HS.404

The main rival of the Spitfire was probably the ME109 during the Battle of Britain and later operations in the war. Both were very capable aircraft and had comparable statistics. Ofcourse, during the Battle of Britain, the Spitfire had the home-field advantage.

In comparison to the Spitfire more ME109s were built. There were 33,984 ME109s to 20,351 Spitfires. This was probably due to the ME109 seeing a lot of action earlier in the war in France and a bit later in Russia.
