    Probably the most famous British fighter in history, the Spitfire is rivalled only by the Mustang in terms of legendary status. Designed in response to the Air Ministry specification F.37/34 to use the new Rolls-Royce PV.12 engine that was later renamed the Merlin. Designed by the dying Reginald Mitchell, the Spitfire was the first all-metal stressed skin fighter produced in Britain. The type saw combat in all theaters of World War II and flew with numerous air forces including the United States Air Force.
    Today the Spitfire is one of the most common warbirds with only the P-51 Mustang being more plentiful.
