The Grumman F6F Hellcat was a carrier-based fighter aircraft conceived to replace the earlier F4F Wildcat in United States Navy service. Although the F6F resembled the Wildcat in some ways, it was a completely new design, powered by a 2,000 hp Pratt & Whitney R-2800 Double Wasp, the same powerplant used for both the Vought F4U Corsair and the United States Army Air Force's Republic P-47 Thunderbolt fighters.
