Grumman F8F Bearcat
Grumman's answer to combat veterans' one demand after Midway — climb faster. Keep the Hellcat's 2,000-hp R-2800, then cut everything else: five feet of fuselage, seven of wingspan, and add the Navy's first bubble canopy. The G-58 first flew in August 1944 — too late for the war.
The F8F Bearcat was Grumman's answer to a single demand from combat veterans: climb faster. After roughly 18 months analyzing Pacific air combat, the team settled on a simple formula — bolt the most powerful American piston engine available, the 2,000-hp Pratt & Whitney R-2800 Double Wasp, into the smallest, lightest airframe that could still survive carrier landings. The internal designation was G-58, and development began in late 1943.
They started from the F6F Hellcat and cut everything they could. The fuselage came out about 5 ft shorter and was lowered behind the cockpit for a bubble canopy — the first on any U.S. Navy fighter — while the wingspan shrank 7 ft. A 12 ft 7 in four-bladed Aeroproducts propeller replaced the Hellcat's three-bladed unit, internal fuel was capped at 160 U.S. gallons to save weight, and armament was held to four .50-cal Brownings.
The XF8F-1 prototype first flew on 21 August 1944 and entered U.S. Navy service on 21 May 1945 — too late for World War II. Grumman and Eastern Aircraft built 1,265 in all. The type later flew for France in Indochina, then Thailand and South Vietnam, which retired it in 1963. Its second life was on the racecourse: heavily modified Bearcats set piston-engine speed records, and one — Rare Bear — reached 528.33 mph in 1989, a mark that still stands.
