- Role: single-seat naval fighter
- Conception: Grumman Aircraft Engineering Corporation
- Production: 12,272 planes built from 1942 to 1945
- First flight of prototype: with R-2600 engine: June 26th, 1942;
with R-2800 engine: July 30th, 1942.

Successor of the Grumman F4F Wildcat, the F6F Hellcat corrected most of the weaknesses
of his predecessor: the F6F offered more power, more ammunition, a better range,
a wide landing gear for easier carrier landings... Designed to be a
Zero killer, it was very manoeuvrable too.
About 6,000 planes were shot down by the Hellcat; the best result ever for a Navy fighter.
Development
- The first Hellcat prototype, called the XF6F-1 and powered by a 1,600 hp Wright R-2600 engine,
was first flown on June 26, 1942.
Grumman also tried the more powerful Pratt & Whitney R-2800 engine in a second prototype,
the XF6F-3, which flew one month later.
- The F6F-3 was the first production Hellcat, powered by a 2,000 hp Pratt & Whitney
R-2800-10 radial engine, and delivery to the Navy started in January 1943.
Contrary to the technically innovative F4U-1 Corsair and thanks
to Grumman's experience with the F4F Wildcat, the Hellcat was
easy to build and to maintain, reliable, and ready from the start to serve aboard carriers.
The F6F-3 soon rolled out of the factories in huge numbers; 4,402 were built until April 1944,
including 18 F6F-3E (with AN/APS-4 radar) and about 200 F6F-3N (with AN/APS-6 radar)
night fighters.
252 were delivered to the British Fleet Air Arm, who baptised it the Gannet Mk.I; the Royal Navy
switched to the American Hellcat nickname in 1944.
Late-production F6F-3 had some features that would become standard on the F6F-5, like
the water-injected R-2800-10W engine or the modified canopy.

- Grumman's XF6F-2 prototype, powered by a turbo-supercharged Wright R-2600 engine, had been
proposed at the same time as the other prototypes.
When the time came for the Navy to ask for a better Hellcat, it was finally tested, then tested again
with a turbo-supercharged Pratt & Whitney R-2800.
The gain in performance of these turbo versions was not interesting enough for the plane to enter production.
- The XF6F-4, powered by the updated R-2800-27, had new weapons: it was armed by four 20mm cannons.
It first flew on October 3, 1942, but never went into production.
- The F6F-5 replaced the F6F-3 on the factory line in the Spring of 1944, and was built
until the end of the war. It featured a modified cowling and canopy, and the P & W
R-2800-10W engine with a water injection boost system. The F6F-5 was able to carry external fuel
tanks, rockets, or a pair of 450 kg (1,000 lb) bombs.
It was called Gannet Mk.II and later Hellcat Mk.II by the British Fleet Air Arm.
7,870 were built, including a few interesting subversions:
the F6F-5E (with the AN/APS-4 radar) and F6F-5N (with the AN/APS-6 radar) were night fighters,
armed with two 20 mm cannons and four 12.7 mm (0.50 cal) guns; 1,434 were built. The F6F-5P was a
photographic reconnaissance version.

- The two XF6F-6 prototypes were powered by the uprated Pratt & Whitney R-2800-18W with a four-bladed
propeller. The end of the war eliminated the need for more Hellcats, and this version able to fly at 671 km/h
(417 mph) was cancelled.

Stof's notes about this plane in iMOL's WarBirds
The opinions expressed below are only my own, and nothing more...
The F6F is not used much in WarBirds's general arena, as most people refuse to bear the lack
of back view. It's still the best carrier-based dogfighter though.
Strong points:
- Really good overall: good top speed and turning abilities, good firepower and ammunition load.
Weak points:
- The roll rate is not impressive, especially when compared to the Corsair's.
- If you look behind you, you see nothing but a head cushion... No back view at all !
