The first aircraft to officially be designated as AT-6 arrived on the scene on April 28, 1939. The mature design, referred to as AT-6, was used in the U.S. by the Army, Navy and the Marines. Produced from 1939 to 1952, usage of the AT-6 and its variants rapidly went global.

Worldwide service was due to many factors. This popular advanced trainer was produced by licensed contractors in the U.S., Britain and Canada. Besides direct contract sales to the U.S. armed services, lend-lease agreements between the U.S. and other nations expanded the service area. Direct sales to other nations, resale between nations, and remanufacturing allowed the global spread of the AT-6 and its variants. It should be noted that, in 1937, both Mitsubishi JUKOGYO K.K. of Japan and the Japanese government separately purchased two late version prototypes of the AT-6 (NA-16s).

One prototype included a 450 hp Pratt & Whitney R-985 engine with a three-bladed prop. The other prototype was shipped unassembled to be used as the model for Japanese licensed production of the K1OW1. From 1930 to the mid-1950s, in addition to the United States, dozens of nations acquired AT-6 series aircraft for use in their armed services. The use of the AT-6 circled the globe. This modest trainer can easily be considered one of the airplanes that won World War II.
