The Supermarine Attacker is a British single-seat naval jet fighter designed and produced by aircraft manufacturer Supermarine for the Royal Navy's Fleet Air Arm (FAA). The type has the distinction of being the first jet fighter to enter operational service with the FAA. Performing its maiden flight on 27 July 1946, the flight testing phase of development was protracted due to several issues, including handling difficulties. The first Attackers were introduced to FAA service during August 1951. Common to the majority of other first-generation jet fighters, the Attacker had a relatively short service life before being replaced; this was due to increasingly advanced aircraft harnessing the jet engine being rapidly developed during the 1950s and 1960s. Despite its retirement by the FAA during 1954, only three years following its introduction, the Attacker would be adopted by the newly formed Pakistan Air Force, who would continue to operate the type possibly as late as 1964.
