Fotogalleri av en Fisher P-75 Eagle, General Motors/Fisher P-75 Örn var ett stridsflygplan konstruerat av Fisher Body Division of General Motors. Utvecklingen startade i september 1942 som svar på United States Army Air Forces krav på en fighter med en extremt hög stigningshastighet, med den mest kraftfulla vätskekylda motorn som då fanns tillgänglig, Allison V-3420. Programmet avbröts efter att endast ett litet antal prototyper och produktionsflygplan hade slutförts, eftersom det inte längre behövdes i sin ursprungliga roll, inte snabbt kunde distribueras och inte hade några betydande fördelar jämfört med flygplan som redan var i produktion.

The Fisher P-75 Eagle was a fighter aircraft project that aimed to create a high-performance interceptor using existing components from other aircraft. The project was initiated by the Fisher Body Division of General Motors in 1942, in response to a request from the US Army Air Forces for a fighter that could climb rapidly and use the Allison V-3420 engine, a 24-cylinder liquid-cooled engine that was the most powerful at the time. The P-75 Eagle design used the outer wing panels from the P-40 Warhawk, the tail assembly from the A-24 (SBD), and the landing gear from the F4U Corsair. The engine was mounted in the middle of the fuselage, driving contra-rotating propellers through a long shaft. The P-75 Eagle was expected to be a “wonder plane” that could outperform any enemy fighter.
However, the P-75 Eagle project encountered many problems during its development and testing. The center of mass was miscalculated, causing stability issues. The engine failed to produce its expected power and had cooling problems. The aileron forces were too high at high speed, and the spin characteristics were poor. The P-75 Eagle also lacked any significant advantage over other fighters already in production, such as the P-51 Mustang and the P-47 Thunderbolt. In 1943, the USAAF changed its requirements and needed long-range escort fighters more than fast-climbing interceptors. Six XP-75 prototypes were modified for the long-range role, but they still did not meet the expectations. In 1944, after only 14 aircraft were built, including two prototypes and 12 production models, the P-75 Eagle project was canceled. The P-75 Eagle was considered a failure and a waste of resources, and none of them ever saw combat.
