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, but there are three reproductions on display with two more under construction.
The project funded by Boeing to produce the Boeing Model 248 began in September 1931, with the US Army Air Corps supplying the engines and the instruments. The open cockpit, fixed landing gear, externally braced wing design was the last such design procured by the USAAC as a fighter. The Model 248 had a high landing speed, which caused a number of accidents. To remedy this, flaps were fitted to reduce the landing speed. The Army Air Corps ordered three prototypes, designated XP-936, which first flew on 20 March 1932.
An air force, also known in some countries as an aerospace force or air army, is in the broadest sense, the national military branch that primarily conducts aerial warfare.
