The North American NA-50 was developed by North American Aviation as a simple single seat, low-wing, single engine fighter for export. The design was developed from the NA-16/BT-9 basic training aircraft of 1935. The NA-16 evolved into a series of aircraft that were some of the most widely used advanced and basic training aircraft produced by any country and provided the basic design for a single engine fighter intended for small countries that needed a simple aircraft with modern capabilities and features.
Peru purchased seven of the North American NA-50 “Torito” (Spanish slang for "little bull") single-seat fighters, factory serial numbers 50-948 to 50-954. Powered by a 840-hp Wright R-1280-77 Cyclone engine, the Peruvian single-seater marked North American Aviation's entry into fighter design. Based on the North American BC-1, the concept was the ideal answer to the need by smaller nations for a lower-cost fighter. The wingspan was shortened to 37 ft 4 in, the sweepBack was reduced and the tips squared The fuselage structure was strengthened to accommodate the 840-hp Wright radial air-cooled engine with a 3-blade propeller. The armament consisted of two cowl-mounted 0.30-in (7.62 mm) Browning M12919 machine guns, two 0.30's in the wings and underwing racks for dive bombing.
North American Aviation pilot Paul Balfour made the first flight on 1 August 1938, and the final acceptance was on 15 April 1939. Peruvian pilots ferried the first three planes to South America and the other four were crated and shipped by boat.
The Peruvian NA-50's took part in the Ecuadorian-Peruvian war of July 1941, supporting Army of Peru ground forces.
NA-50 XXI-41-3 (c/n 50-950). One of the original seven NA-50's built is displayed on a pedestal in front of the Museo Aeronáutico del Perú at Las Palmas Air Base, Lima, Peru, and next to the Mausoleum of Captain José Quiñones Gonzáles, (a Peruvian national hero who died while flying an NA-50). This example was initially assigned to Escuadrón de Aviación No.1 (Chiclayo Field) and was later transferred to the 28th Advanced Fighter Training Group, 4th squadron until retired in 1967.
A replica of the NA-50 was built from a Canadian Harvard and is currently airworthy.
