The Boeing P-26 is a historic American fighter aircraft that first flew in 1932. It was notable for being the first all-metal monoplane fighter used by the United States Army Air Corps. The P-26 featured a distinctive design with a low-wing configuration and an open cockpit, which set it apart from earlier biplane fighters. The aircraft was powered by a Pratt & Whitney R-1340 Wasp engine, allowing it to reach speeds of around 200 miles per hour. Although it was eventually phased out in favor of more advanced fighters, the P-26 remains an important part of aviation history and is often celebrated for its innovative design.
