The Vindicator was a decent aircraft when it was accepted in 1936 as the U.S. Navy's first monoplane scout bomber. It was the product of a call for comparative trials between a modern biplane and modern monoplane design. The monoplane design proved much superior and was put into production in October 1936. Deliveries began in December 1937.

A small number were ordered by the French as the V-156F, and 24 had been delivered by May 1940. Half of these were wiped out on the first day of the German invasion. Those aircraft not yet delivered to the French were taken over by the British, who ordered an additional 50 as the Chesapeake Mark I.

The Vindicator was clearly obsolete by the start of the Pacific War. A few –3s saw action with the Marines at Midway, suffering relatively light casualties but failing to get any hits. Its crews sardonically referred to it as the "Wind Indicator."
