In addition to reputations for aircraft performance, aviation design firms had penchants for either innovation or adhering to convention.

Grumman Aircraft was known for its workman-like designs which grew more sophisticated, but at a conservative pace. There was an undeniable steppingstone progression in their fighter designs from the biplane FF-1 of 1931 up to their last piston fighter, the F8F Bearcat of 1943. Among their jets, this conservatism is reflected in the F9F Panther, it’s first jet fighter, up to the F11F Tiger.
