In 1942 the USAAF asked for designs for a high performance fighter with an unprecedented rate of climb, to intercept Japanese bombers in the Pacific theater. The Fisher Body Division of General Motors submitted a design for an aircraft that would use the most powerful inline engine then available, as well as "off-the-shelf" major assemblies (which would shorten development times). The P-75 airframe used the outer wing panels of the Curtiss P-40, the tail unit of the Douglas A-24/Dauntless, and landing gear of the Vought F4U Corsair. The engine was located in the fuselage behind the pilot, similar to the layout of the Bell P-39. Eight prototypes were ordered by the USAAF, but problems were found during testing. By the time the problems were fixed, other capable fighters (like the P-51 Mustang) were available, and the production contract was cancelled.
