In the mid-1930s, the Army Air Corps wanted a plane capable of matching the world's fastest pursuit aircraft -- British Hurricanes and Spitfires. When the Allison V-1710 inline engine became available, Curtiss designed an aircraft based on the P-36 for the new engine and guaranteed a top speed of 340 mph. The result was the XP-37, which featured two side-radiators mounted behind the engine and a cockpit well aft of the wing. The cockpit placement, which limited the pilot's forward view, combined with the poor performance of the turbo-supercharger, led to the cancellation of the project; although 13 YP-37 service test models were built around a lengthened fuselage before the project was terminated.
