The Northrop A-17, a development of the Northrop Gamma 2F was a two-seat, single-engine, monoplane, attack bomber built in 1935 by the Northrop Corporation for the U.S. Army Air Corps. A-17s used by air forces of the British Commonwealth designated the aircraft as the "Nomad."
The Northrop Gamma 2F was an attack bomber derivative of the Northrop Gamma transport aircraft, developed in parallel with the Northrop Gamma 2C, (of which one was built), designated the YA-13 and XA-16. The Gamma 2F had a revised tail, cockpit canopy and wing flaps compared with the Gamma 2C, and was fitted with new semi-retractable landing gear. It was delivered to the United States Army Air Corps for tests on 6 October 1934, and after modifications which included fitting with a conventional fixed landing gear, was accepted by the Air Corps. A total of 110 aircraft were ordered as the A-17 in 1935.
The resulting A-17 was equipped with perforated flaps, and had fixed landing gear with partial fairings. It was fitted with an internal fuselage bomb bay that carried fragmentation bombs and well as external bomb racks.
Northrop developed a new landing gear, this time completely retractable, producing the A-17A variant. This version was again purchased by the Army Air Corps, who placed orders for 129 aircraft. By the time these were delivered, the Northrop Corporation had been taken over by Douglas Aircraft Company, export models being known as the Douglas Model 8.
The A-17 entered service in February 1936, and proved a reliable and popular aircraft. However, in 1938, the Air Corps decided that attack aircraft should be multi-engined, rendering the A-17 surplus to requirements.
From 14 December 1941, A-17s were used for coastal patrols by the 59th Bombardment Squadron (Light) on the Pacific side of the Panama Canal.
The last remaining A-17s, used as utility aircraft, were retired from USAAF service in 1944.
Argentina purchased 30 Model 8A-2s in 1937 and received them between February and March 1938. Their serial numbers were between 348 and 377. These remained in frontline service until replaced by the I.Ae. 24 Calquin, continuing in service as trainers and reconnaissance aircraft until their last flight in 1954.
