The Douglas Model 8A-2 was an export version of the fixed-undercarriage A-17 intended for the Fuerza Aerea Argentina. Test pilot Eddie Allen had demonstrated the Northrop Model 5B in Buenos Aires in 1935, and 30 Model 8A-2s were ordered. They were built and shipped to Argentina in 1938.
The Model 8A-2 was powered by the 840 hp Wright R-1820-G3 radial, and was armed with two 12.7 and two 7.6-mm wing-mounted machine guns and one flexible rear-firing 7.6-mm machine gun. The Model 8A-2 was fitted with a partially-retractable bomb-aiming tub underneath the rear cockpit. Company numbers were 348 to 377. FAA serials were A-401 throu A-430 (later O-401 through O-430).
The Model 8A-2s were operated by the Fuerza Aerea Argentina's Regimiento de Ataque No 2, first from El Palomar and then from El Plumerillo. The Model 8A-2s were eventually replaced by the indigenous I.Ae.24 Calquin twin-engined bomber. Surviving examples were transferred to El Palomar, near Buenos Aires, where they were operated as advanced trainers until 1955.
