More often than not, the expiremental planes from any country turned out hideous. This is the P-75 Eagle. The US wasted time and money producing a brand new factory produce it (rather than openinning a second line for P-38s) and it was absolutely horrible.
The prototype was literally composed of parts from other planes. The tailfin was from an SBD, the outer wings from a P-40, and the main landing gear from a F4U.
