After an unusually long development time (development began as early as 1946 but the system was not fielded until 1951), the RAF version was accepted into operational service with average results. The Royal Navy, however, took an interest in the Supermarine product and began arming their Fleet Air Arm (FAA) with the new Attacker as a carrier-based jet fighter. The Attacker would become the first jet-powered aircraft to be brought aboard British naval carriers.
Once on the ships, the Attacker performed solidly though without much fame. The system would provide the British Royal Navy with a stepping stone to more advanced turbojet-powered alternatives in years to come for the Attacker was eventually weeded out from frontline carrier service as soon as 1954.
The Supermarine Attacker was a single engine jet fighter of ordinary design. The base model of the Spiteful piston aircraft shown through in its design as the aircraft sat with a noticeable "nose-up" appearance when at rest - a throwback to the days of the World War 2 "tail draggers" - this despite the use of a tricycle undercarriage. This nose-up attitude forced the aircraft to rest on a forth, albeit smaller, landing gear system at rear. The pilot sat high and forward on the fuselage with intakes to either side of the cockpit. The twin intakes aspirated the single turbojet engine buried deep within the fuselage center. A single vertical tail fin was mounted atop the empennage ahead of the engine exhaust ring. Wings were straight-wing assemblies and generally consistent with other early turbojet fighters. The Attacker was adequately armed with a battery of 4 x 20mm Hispano cannons, each mounted in the wing leading edge in pairs (noted in photographs by the extending muzzles).
In all, just 182 examples were produced as well as three prototypes. Ultimately, the Attacker was replaced in British service by the Hawker Sea Hawk and de Havilland Sea Venom.
