What was special about the Hellcat's design among American World War II fighters?

Short answer

It was a carrier fighter designed to be easy to build and to withstand damage, with widely spaced, hydraulically operated landing gear legs that rotated 90° as they retracted back into the wings, and wings that folded along Grumman's patented diagonal Sto-Wing axis. The downward-sloping nose gave good visibility.

What was special about the Hellcat's design among American World War II fighters?

Built for the factory and for punishment

The design aimed at two things: ease of manufacture and the ability to withstand major damage. That approach came from the Wildcat, the fighter the Hellcat succeeded. The F6F series was conceived to take hits and bring the pilot back to base safely. Along with its good flying qualities, the Hellcat was easy to maintain and had a structure robust enough to withstand the rigors of routine carrier operations.

Gear, wings and visibility

Its widely spaced, hydraulically operated landing gear legs rotated 90° as they retracted backward into the wings. The wings folded backward, pivoting on a specially oriented diagonal axis patented by Grumman, the Sto-Wing system. The forward fuselage sloped slightly down toward the engine cowling, giving the pilot good visibility.

The result in combat

Against Japan's best opponents, the Hellcat is credited with a kill ratio of 13:1 against the A6M Zero, 9.5:1 against the Nakajima Ki-84, and 3.7:1 against the Mitsubishi J2M.
