The I.Ae. 21 DL, also known as the FMA I.A.21 or FMA 21, was an experimental light fighter developed by Argentina during the Second World War. While only one was built due to material constraints, the FMA 21 served as an advanced training aircraft for the Argentine Air Force (FAA) from 1943-1945.[1][2]

The FMA 21 was developed by Argentinian government-owned aircraft manufacturer Fábrica Militar de Aviones (FMA, now Fábrica Argentina de Aviones). Due to souring politicial relations between Argentina and the United States, FMA decided to use their experience with the North American NA-16 in service with the FAA to develop their own domestic fighter,[3] so the FMA 21 was heavily based off the fuselage of the NA-16.[4] It was also featured the first retractable landing gear built in the country.[1]

Construction

The FMA 21's fuselage consisted of welded chrome-molybdenum steel tubes covered in a duraluminium coating. The cockpit had a sliding all-acrylic canopy and was configured for tandem control.[1]

The aircraft was propelled by a Wright R-975-E3 Whirlwind that generated 450 hp at 2250 r.p.m and drove a two-bladed variable-pitch propeller.[1][5]
