Hawker Sea Hawk - Operational History

Operational History

The first production Sea Hawk was the F 1, which first flew in 1951, entered service two years later with 806 Squadron, first based at Brawdy, then transferred to the HMS Eagle. Just over 30 were actually built by Hawker. At that time, Hawker was also producing the Hawker Hunter for the RAF and so production and further development of the Sea Hawk was switched to Armstrong Whitworth Aircraft, part of the Hawker group. The F 1 was armed with four 20 mm (.79 in) Hispano Mk V cannons. It was powered by a single 5,000 lbf (22 kN) thrust Rolls-Royce Nene 101 turbojet. The F 1 had a maximum speed of 599 mph (964 km/h) at sea level and a range of 800 mi (1,287 km) on internal fuel. The second fighter variant was the F 2 which introduced power-boosted aileron controls as well as other modifications, including to its structure.

The next variant of the Sea Hawk was developed into a fighter-bomber, the FB 3 - Fighter-Bomber Mark 3 -(over 100 built) and differed only slightly from its predecessors. Its structure was strengthened to allow it to carry a wide array of equipment and weaponry. Its new armament consisted of two 500 lb (227 kg) bombs and 16 unguided rockets. The fourth Sea Hawk was a fighter ground-attack variant, the FGA 4, with increased weapons capability. The fifth Sea Hawk was a fighter-bomber variant, the FB 5, basically FB 3 and FGA 4s re-engined with the new Rolls-Royce Nene 103. The final Sea Hawk was a fighter ground-attack variant, FGA 6, and was exactly the same as its immediate predecessor, though they were new builds rather than re-engined, with just under 90 built. All Sea Hawks were in service by the mid-1950s and eventually over 500 were built.

Although Australia and Canada both initially expressed interest in the Sea Hawk, to the extent that examples were tested by each country's naval forces, the first export version was the Sea Hawk Mk 50, a ground-attack variant for the Royal Netherlands Navy; 22 aircraft were in service between 1957 to 1964. The next export variant was the Sea Hawk Mk 100, a strike fighter variant for the German Bundesmarine, the Navy of West Germany. The final German export version was the Sea Hawk Mk 101, a night fighter, reconnaissance variant for the Bundesmarine. The Sea Hawk served into the mid-1960s, until its replacement by the F-104 Starfighter. The last export customer was India who ordered a mix of 24 new-build Sea Hawks and 12 refurbished ex-FAA Mk 6s in 1959, following up with 30 additional airframes reconstructed from West German stocks, among others.
