The Fisher P-75 Eagle was intended to fill the Army Air Forces' 1942 need for an interceptor. Its unique design featured two coaxial contra-rotating propellers connected by dual drive shafts running under the cockpit to a 24-cylinder liquid cooled engine located amidships. The original concept called for use of proven airframe components, such as P-40 wing panels, A-24 tail and F4U landing gear, to reduce the design and testing period.
The first of two XP-75s using component parts made its initial flight on Nov. 17, 1943. Flight tests revealed unsatisfactory performance. This, combined with a mission change from interceptor to long-range escort, caused major changes in the original design. Ultimately, the idea of using proven airframe components had to be abandoned. The AAF ordered six XP-75s of the revised configuration along with 2,500 P-75As. The improved version was still unsatisfactory and after three Eagles had crashed, the entire program was cancelled on Nov. 8, 1944. Only eight XP-75s and six P-75As were built.
