The North American Aviation T-28 Trojan is a piston-engined military trainer aircraft used by the USAF and U.S. 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. On 24 September 1949, the XT-28 (company designation NA-159) was flown for the first time, designed to replace the T-6 Texan. Found satisfactory, a contract was issued and between 1950 and 1957, a total of 1,948 were built.

 

Die Trojan von North American Aviation T-28 ist ein militärisches Schulflugzeug mit Kolbenmotor, das in den 1950er Jahren von der USAF und der U.S. Navy eingesetzt wurde. Neben seiner Verwendung als Trainer wurde die T-28 vor allem während des Vietnamkriegs erfolgreich als Aufstandsbekämpf-ungsflugzeug eingesetzt. Am 24. September 1949 wurde die XT-28 (Firmenbezeichnung NA-159) zum ersten Mal geflogen, um die T-6 Texan zu ersetzen. Als befriedigend befunden wurde ein Vertrag und zwischen 1950 und 1957 für insgesamt 1.948 Maschinen abgeschlossen.

Operational history

Einsatzgeschichte

 

The first 16 T-28s of the Royal Khmer Air Force were acquired in May and August 1962. In 1970 the ARVK had only 6 operational T-28Ds.

 

On 21. March 1964 two Cambodian T-28Ds surprised a VNAF O-1 inside the Khmer airspace. The Cambodian flight leader, Captain (Prince) Sisowat Monirak took a position behind the South Vietnamese and shot it down two miles inside South Vietnamese territory, killing the Vietnamese pilot and the US observer. Despite Cambodian propaganda presenting Prince Monirak as a hero, Sihanouk ordered the AVRK in the future not to pursue intruding aircraft over the border.

 

In the night of the 21 January 1971, most ARVK T-28s were destroyed during a sapper attack on Pochentong Air Base.
