It was superior in performance and firepower to its predecessor, the Fulmar, but only entered operational service towards the end of the war. Designed around 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 overall performance.

The Fairey Firefly served in the Second World War as a fleet fighter but in postwar service, although it was superseded by more modern jet aircraft, the Firefly was adapted to other roles, including strike operations and anti-submarine warfare, remaining a mainstay of the FAA until the mid-1950s. Both the UK and Australia Fireflies flew ground attack operations off various aircraft carriers in the Korean War. In foreign service, the type was in operation with the naval air arms of Australia, Canada, India, and the Netherlands whose Fireflies carried out a few attack sorties as late as 1962 in Dutch New Guinea.

Below is a list of Firefly airframes that survived military service.
