Hughes OH-6A Cayuse

History

The Boeing (McDonnell Douglas) (formerly Hughes model 369A) OH-6A, was designed for use as a military scout during the Vietnam war to meet the U.S. Army's need for an extremely maneuverable light observation helicopter (LOH program). The Hughes OH-6A Cayuse was quite effective when teamed with the AH-1G Cobra attack helicopter as part of what were known as Pink Teams. The OH-6A Loach would find targets by flying low, "trolling" for fire, and lead in a Cobra, or Snake, to attack.

This aircraft serviced in Vietnam with the 17th Cavalry, Troop C, from February 1969 to February 1970 and with the 5th AVN Det., AVN TNG Team, 8th Cavalry F Troop, 17th Air Cavalry, H Troop, May 1971 to January 1973. Also serviced with NASA January 1973 to May 1973 and the Connecticut Air National Guard from November 1975 to October 1976.
