The A-17 series was a direct descendent of the pace setting Northrop "Gamma", made famous by the aerial explorer Lincoln Ellsworth. It replaced the Curtiss A-8 and A-12 Shrike and was the last of the pre-war single-engine attack aircraft ordered into production by the Army Air Corps.

Caught in the pre-World War II doctrine that emphasized air superiority over ground support, the A-17 was never fully tested in peacetime exercises or in combat. Its fate was sealed in 1938 when the Army Air Corps determined that all future attack aircraft procured would be multi-engine models.

Despite this handicap, the A-17's design and novel features such as split perforated flaps figured prominently in the success of a distinguished line of Douglas aircraft including the Dauntless dive bomber and the post World War II Skyraider.

The first 109 production A-17s featured fixed, partially enclosed landing gear. One hundred and twenty nine A-17As configured with fully retractable landing gear and a more powerful engine followed between February 1937 and August 1938.

The A-17A could lift over one ton of bombs. The bombs were carried on four external racks and in an internal bomb bay that featured vertical chutes, which held up to twenty 30 lb. fragmentation bombs. In addition to the bombs, the A-17A was armed with four forward firing .30-caliber machine guns for strafing, and one flexible mounted .30-caliber gun in the rear cockpit for self-defence.

A-17As saw unit service for less than four years. In June 1940, all but 20 A-17As were sold overseas. The remaining Army Air Forces A-17 and A-17As were used as advanced trainers and squadron support aircraft, most ending up as ground maintenance trainers. The last A-17A was written off of Army Air Forces records in early 1945.
