Lockheed XFM-2

The Lockheed XFM-2, first designated XPB-3, was a proposed American heavy fighter designed by the Lockheed Corporation in the mid-1930s and known inside the company as the Model 11. The United States Army Air Corps wanted a heavy twin-engined bomber destroyer, and the design was first placed in the pursuit biplace category before being redesignated fighter, multiplace. It was a mid-wing monoplane of nearly medium bomber size with a tricycle landing gear and twin tails, to be powered by two supercharged Allison V-1710 engines and armed with two 37 millimetre cannons, one in a nose turret and one in a dorsal turret behind the cockpit. The Air Corps evaluated it favourably, but it chose the Bell YFM-1 Airacuda instead, no prototype was built, and further work on the design was abandoned.
