The P-26, also known as the Boeing P-26 Peashooter, was a fighter aircraft used by the United States Army Air Corps in the 1930s. It was notable for being the first all-metal monoplane fighter in U.S. service, featuring a distinctive round fuselage and a biplane wing design. The P-26 was powered by a Pratt & Whitney R-1340 Wasp engine, allowing it to reach speeds of around 200 miles per hour. Introduced in 1932, the P-26 served primarily in the pre-World War II era and was gradually phased out as more advanced aircraft became available. Despite its limited combat use, the P-26 played a significant role in the evolution of military aviation and influenced the design of future fighters.
