The Boeing P-26 "Peashooter" was the first American production all-metal fighter aircraft and the first pursuit monoplane to enter squadron service with the United States Army Air Corps. Designed and built by Boeing, the prototype first flew in 1932, and the type was still in use with the U.S. Army Air Corps as late as 1941 in the Philippines. There are two surviving Peashooters and three reproductions on display, with two more under construction.
