Intro
Uncover the story of the Fisher P-75 Eagle, Americas forgotten fighter plane. Learn about its development, design, and performance, as well as its limited production and deployment during WWII. Discover how this aircraft, with its unique blend of P-51 Mustang and P-40 Warhawk features, remains a fascinating footnote in aviation history.
The Fisher P-75 Eagle is one of the most fascinating yet forgotten fighter planes in American aviation history. Developed during World War II, this aircraft was designed to be a high-performance, multi-role fighter that could take on the best of the enemy's planes. Despite its impressive design and capabilities, the P-75 Eagle never saw combat and was eventually relegated to the annals of history. In this article, we will delve into the story of the Fisher P-75 Eagle, exploring its development, design, and the reasons behind its obscurity.
Development and Design
The Fisher P-75 Eagle was designed by the Fisher Body Division of General Motors, a leading manufacturer of aircraft components and automotive bodies. In 1942, the US Army Air Forces (USAAF) issued a request for proposals for a new fighter plane that could replace the P-40 Warhawk and P-47 Thunderbolt. Fisher's design team, led by engineer Erik Nessler, set out to create an aircraft that would meet the USAAF's requirements.
The P-75 Eagle was a single-seat, single-engine fighter plane with a unique design. It featured a rear-mounted engine, a pusher propeller, and a tricycle landing gear. The aircraft was powered by a General Electric I-40 turbojet engine, which produced 4,200 pounds of thrust. The P-75 Eagle's airframe was made of aluminum and steel, with a wing span of 49 feet and a length of 40 feet.
Key Features and Innovations
The Fisher P-75 Eagle had several innovative features that set it apart from other fighter planes of its time. Some of its key features included:
- A rear-mounted engine, which reduced the risk of engine damage from enemy fire
- A pusher propeller, which improved visibility for the pilot and reduced the risk of propeller damage
- A tricycle landing gear, which made the aircraft more stable and easier to handle
- A General Electric I-40 turbojet engine, which provided exceptional power and performance
Despite its impressive design and features, the P-75 Eagle had several drawbacks. The aircraft was heavy, with a maximum takeoff weight of over 20,000 pounds. It also had a high stall speed, which made it difficult to handle at low speeds.
Testing and Evaluation
The Fisher P-75 Eagle underwent extensive testing and evaluation by the USAAF. The first prototype, XP-75, made its maiden flight in November 1943. The aircraft performed well in initial tests, with a top speed of over 430 mph and a range of over 2,000 miles.
However, further testing revealed several issues with the P-75 Eagle's design. The aircraft was prone to engine failure, and its high stall speed made it difficult to handle. Despite these issues, the USAAF ordered 2,500 P-75 Eagles in 1944.
Cancellation and Legacy
The Fisher P-75 Eagle never saw combat due to a combination of factors. The aircraft's development was slow, and it was eventually eclipsed by other fighter planes, such as the P-51 Mustang and P-47 Thunderbolt. The USAAF cancelled the P-75 Eagle program in 1945, citing a lack of need for the aircraft.
Despite its obscurity, the Fisher P-75 Eagle played an important role in the development of American fighter planes. Its innovative design and features influenced the development of later aircraft, such as the F-86 Sabre and F-100 Super Sabre.

Comparison to Other Fighter Planes
The Fisher P-75 Eagle was a unique aircraft that compared favorably to other fighter planes of its time. Here's a comparison of the P-75 Eagle to other notable fighter planes:
- P-51 Mustang: The P-51 Mustang was a more successful fighter plane that saw extensive combat in World War II. It had a similar top speed to the P-75 Eagle but had a longer range and better maneuverability.
- P-47 Thunderbolt: The P-47 Thunderbolt was a larger and heavier fighter plane than the P-75 Eagle. It had a similar top speed but had a shorter range and poorer maneuverability.
- F-86 Sabre: The F-86 Sabre was a later fighter plane that was influenced by the P-75 Eagle's design. It had a similar top speed and range but had better maneuverability and a more advanced design.
