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 aircraft, primarily during the Vietnam War. It has continued
in civilian use as an aerobatics and Warbird performer.
On September 24, 1949, the XT-28 (company designation NA-159) was flown for the
first time, designed to replace the T-6 Texan. The T-28A arrived at the Air
Proving Ground, Eglin Air Force Base, Florida, in mid-June 1950, for suitability
tests as an advanced trainer by the 3200th Fighter Test Squadron, with
consideration given to its transition, instrument, and gunnery capabilities.
Found satisfactory, a contract was issued and between 1950 and 1957, a total of
1,948 were built.
Following the T-28's withdrawal from U.S. military service, a number were
remanufactured by Hamilton Aircraft into two versions called the Nomair. The
first refurbished machines, designated T-28R-1 were similar to the standard
T-28s they were adapted from, and were supplied to the Brazilian Navy. Later, a
more ambitious conversion was undertaken as the T-28R-2, which transformed the
two-seat tandem aircraft into a five-seat cabin monoplane for general aviation
use. Other civil conversions of ex-military T-28As were undertaken by PacAero as
the Nomad Mark I and Nomad Mark II.

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 from 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 Naval Air Station 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
Air Station 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
Support Facility Anacostia, D.C.
In 1963, a Royal Lao Air Force T-28 piloted by Lieutenant Chert Saibory, a Thai
national, defected to North Vietnam. Saibory was immediately imprisoned and his
aircraft was impounded. Within six months the T-28 was refurbished and
commissioned into the North Vietnamese Air Force as its first fighter aircraft.
T-28s were supplied to the South Vietnamese Air Force in support of ARVN ground
operations, seeing extensive service during the Vietnam War in VNAF hands, as
well as the Secret War in Laos. A T-28 Trojan was the first US fixed wing attack
aircraft (non-transport type) lost in South Vietnam, during the Vietnam War.
Capt. Robert L. Simpson, USAF, Detachment 2A, lst Air Commando Group, and Lt.
Hoa, SVNAF, were shot down by ground fire on August 28, 1962 while flying close
air support. Neither crewman survived. The USAF lost 23 T-28s to all causes
during the war, with the last two losses occurring in 1968.
