The Fairey Firefly was a British Second World War-era carrier-borne fighter aircraft and anti-submarine aircraft of the Fleet Air Arm (FAA). It was superior in performance and firepower to its predecessor, the Fulmar but entered operational service only towards the end of the war. Designed to the contemporary FAA concept of a two-seat fleet reconnaissance/fighter, the pilot and navigator/weapons officer were housed in separate stations. The design proved to be sturdy, long-ranging and docile in carrier operations, although the limitations of a single engine in a heavy airframe reduced its performance.
