The Sea Hawk began to enter service in 1953 with 806 squadron at Brawdy. By 1955 the Sea Hawk performance was already considered mediocre which led to the installation of the more powerful 5,200 lb thrust Nene 103 and the use of the Sea Hawk as a ground attack aircraft, cleared to carry external stores, a task at which the Sea hawk excelled. In all 434 Sea Hawks were built for the Royal Navy, the largest production run for any British naval jet fighter. The Sea Hawk remained in service until 1960 with the Royal Navy, but the Sea Hawk story does not end there. The Sea Hawk was a major export success, the Indian Navy finally retiring it's last example in 1984. The Sea Hawk FGA MK.6 evolved as an analogous FGA.4 upgrade with the Nene MK.103 unit, of which some 30 were made. As a supplement, early in 1955,an order for 95 new-build MK.6 was placed by the MAP,But only 87 were finished by 1956.
