The first production model was the F6F-3 and it had a Pratt & Whitney R-2800-10 Double Wasp Engine that was capable of propelling it at speeds of up to 605 km/h.
Its armament consisted of six 12.7mm browning machine guns and it was noted by its crews to be extremely reliable and the inclusion of armor protection and self sealing fuel tanks only further proved the F6F to be an excellent design.
Furthermore, the Hellcat was able to carry numerous types of payloads for ground and shipping attacks such as bombs, rockets, and torpedos. A maximum of 900 kg worth of explosives could be carried.
The total weight of the system was about 4,100 kg while its total length was 10.3 meters. The F6F also had a service ceiling of 11,300 meters and an operational range of 1,500 kilometers, specifically designed so that the aircraft was well capable of fighting effectively in the Pacific.
The first variant of the Hellcat series was the Hellcat Mk I which was the British modification to the original F6F-3.The next major variants were the F6F-5 and Hellcat Mk II modifications which both had modified air frames and engine equipment for combat operations. In between were numerous sub variants such as the F6F-3E with special radar equipment for long distances. Furthermore, 149 F6F-3N and 1,434 F6F-5N aircraft were fitted with an APS-6 radar unit in a pod attached to one wing, and operated as night fighters.
The initial Hellcat contract was for two prototypes of a successor to the F4F Wildcat, incorporating lessons from the conflict in Europe and the opinions of US Navy pilots, in order to provide an insurance against failure of the XF4U-1. The contract was awarded to Grumman on June 30 1941, The resulting XF6F-1 made it's first flight on June 26 1942, powered by a Wright R-2600 Cyclone producing 1,600 hp which, following consultation with US pilots who had fought the A6M Zero, was replaced in future examples with the Pratt & Whitney R-2800 Double Wasp.
The second prototype was the first example to use the new engine, making it's first flight as the XF6F-3 on July 30 1942. Production of the F6F had been ordered on May 23 1942, with the first ten being completed by the end of the year, the first of these flying on October 4 1942. F6F-3s made their first combat flights on 31 August and 1 September 1943, from the carriers Yorktown (CV-10), Essex (CV-9), and the light carrier Independence (CVL-22).
