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 US Army Air Corps.
Development and design
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 a new semi-retractable undercarriage. It was delivered to the United States Army Air Corps for tests on 6 October 1934, and after modification, including fitting with a conventional fixed undercarriage, was accepted by the Air Corps. 110 aircraft were ordered as the A-17 in 1935
The resulting A-17 was equipped with perforated flaps, had fixed landing gear with partial fairing. It was fitted with an internal fuselage bomb bay that carried fragmentation bombs and well as external bomb racks.
Northrop developed a new undercarriage, 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.
[edit] Operational history
A-17A cockpitThe 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.
In 1939, 93 ex-USAAC aircraft were purchased by France and given new engines. Not having been delivered before the fall of France, 61 were taken over by the British Purchasing Commission for the RAF and given the name Nomad. They were assessed as being obsolete and sent to South Africa for use as trainers.The remaining thirty two aircraft from the French order were transferred to Canada, where they were also used as advanced trainers
The last remaining A-17s, used as utility aircraft, were retired from USAAF service in 1944.
