North American T-28 Trojan
1949 military trainer aircraft family by North American Aviation
The North American Aviation T-28 Trojan is a radial-engine military trainer aircraft manufactured by North American Aviation and 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.
Design and development
On 24 September 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
Operational history
After becoming adopted as a primary trainer by the USAF, the United States Navy and Marine Corps adopted it as well.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
