The Ambitious Pursuit: The Republic XP-69 Fighter

In 1940, the United States Army Air Corps rolled out a bold challenge, the R40-C fighter competition. They sought high-speed fighter aircraft proposals that dared to be unorthodox. The target was a single-engine fighter with a speed range of 425 to 525 mph, equipped with machine guns, cannons, and an ability to land on a 3,000 ft grass runway.
