The Lockwell P-76 Victory Viper is an outstanding aircraft, both fast and well armored. Armed with two 12.7mm cannon, and two 37mm cannon, it can bring an impressive amount of firepower to bear on it's target.

This is a fighter plane I've drawn up for an crimson skies inspired RP on Feila. I tried to come up with a sort of hybrid of the Vic Viper (from the Gradius series) and a Lockheed P-38 Lightning. I think it turned out pretty well, and I'm happy with the final product.
