The "Beercat" never got the fame it deserved as a genius aircraft design due to timing. That and it's too late for the war stablemate, the Tigercat. Apparently Leroy Grumman, a legitimate test pilot in his own right, flew a captured FW190 in England and said "this is the plane we should have built". The Bearcat was designed to produce a carrier plane of about the same size and weight with superior performance. Wrap the smallest possible plane around the ubiquitous R2800 C series.
With the Tigercat the navy's chief test pilot wrung it out and lands and catalogues all its faults, then says "best damn fighter I ever flew". Speed, climb, 4 50 cal and 4 20 mm! One of my favorite projects for Milton Shupe!
