Design

The Vultee Valiant started out as a private venture, the Vultee Model 54, and was tested by the United States Army Air Corps (USAAC). in 1938.1 The Vultee Model 54 had a Wright R-1340 (600 HP) engine and retractable landing gear.1 This was considered to powerful and complicated for basic training.1 Vultee redesigned the plane to have fixed landing gear and a less powerful engine.1

Engines

Pratt & Whitney couldn't keep up with production of their R-985 Wasp engines so Wright produced around 1,700 R-975 Cyclones that were fitted in the BT-15.1

Production

In September 1939 the USAAC ordered 300 Valiants.1 In 1941 a follow up order of 2,000 was placed.1

In August 1940 the United States Navy ordered Valiants.1
