On September 24, 1949, the prototype XT-28 took its maiden flight. It was built as a replacement on the T-6 Texan single-engined trainer. In mid-June 1950, the United States Air Force version T-28A went to the Air Proving Ground at Eglin Air Force Base, Florida to perform suitability tests.

The aircraft was produced from 1950 to 1957 with a total number of 1,948 built. In 1962, the T-28Bs were modified for the United States Air Force for roles such as counter-insurgency, forward air controller, reconnaissance, and search and rescue in Vietnam. The converted aircraft were designated as T-28Ds.
