Galerie de photos d’un Fisher P-75 Eagle, The General Motors/Fisher P-75 Aigle était un avion de chasse conçu par la Fisher Body Division de General Motors. Le développement a commencé en septembre 1942 en réponse à l’exigence de l’armée de l’air des États-Unis pour un chasseur possédant un taux de montée extrêmement élevé, en utilisant le moteur liquide le plus puissant refroidi alors disponible, l’Allison V-3420. Le programme a été annulé après qu’un petit nombre seulement de prototypes et d’avions de production ont été achevés, car il n’était plus nécessaire dans son rôle initial, n’a pas pu être déployé rapidement et ne possédait aucun avantage significatif par rapport aux aéronefs déjà en production.

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 « Avion Wonder » 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.
