Series production

F6F-3 (British designation Gannet F. Mk. I, and then later, renamed Hellcat F. Mk. I, January 1944)

Single-seat fighter, fighter-bomber aircraft, powered by a 2,000 hp (1,491 kW) Pratt & Whitney R-2800-10 Double Wasp radial piston engine.


Night fighter version, equipped with an AN/APS-4 radar in a fairing on the starboard outer wing.


Another night fighter version, equipped with a newer AN/APS-6 radar in a fairing on the starboard outer wing.

F6F-5 Hellcat (British Hellcat F. Mk. II)
