This is the only A-17 series aircraft known to exist. It was delivered to the Air Corps and assigned to Barksdale Field, Louisiana, on June 25, 1937. The A-17's design and novel features, such as split perforated flaps, figured prominently in the future success of a distinguished line of Douglas aircraft, including the Dauntless dive bomber.

Caught in the pre-WWII 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.
