The North American Aviation T-28 Trojan is a piston-engined military trainer aircraft used by the United States Air Force and United States Navy beginning in the 1950s. Besides its use as a trainer, the T-28 was successfully employed as a Counter-insurgency (COIN) aircraft, primarily during the Vietnam War.
After becoming adopted as a primary trainer by the USAF, the United States Navy and Marine Corps adopted it as well. Although the Air Force phased out the aircraft out of primary pilot training by the early 1960s, continuing use only for limited training of special operations aircrews and for primary training of select foreign military personnel, the aircraft continued to be used as a primary trainer by the Navy (and by default, the Marine Corps and Coast Guard) well into the early 1980s.
The largest single concentration of this aircraft was employed by the U.S. Navy at NAS Whiting Field in Milton, Florida in the training of student naval aviators. The T-28's service career in the U.S. military ended with the completion of the phase in of the T-34C turboprop trainer. The last U.S. Navy training squadron to fly the T-28 was VT-27, based at NAS Corpus Christi, Texas, flying the last T-28 training flight in early 1984. The last T-28 in the Training Command, BuNo 137796, departed for Naval District Washington on 14 March 1984 to be displayed permanently at Naval Station Anacostia, D.C. Many T-28s were subsequently sold to private civil operators, and due to their reasonable operating costs are often found flying as warbirds today.
