History Hughes Helicopters, Inc. MD
Hughes OH-6 Cayuse
Manufactured 1965–present
Introduction date 1966
First flight 27 February 1963
The Hughes OH-6 Cayuse is a single-engine light helicopter designed and produced by the American aerospace company Hughes Helicopters. Its formal name is derived from the Cayuse people, while its "Loach" nickname comes from the acronym for the Light Observation Helicopter (LOH) program under which it was procured.
During 1960, the United States Army issued Technical Specification 153 for a Light Observation Helicopter (LOH) capable of fulfilling various roles on the battlefield, including personnel transport, escort, casualty evacuation, observation, and attack missions. These would be used to replace its fleet of Bell H-13 Sioux, a compact first generation rotorcraft. Twelve companies opted to participate in the competition, Hughes Tool Company's Aircraft Division being one of them, submitted the Model 369 as its response. Two of these designs, those submitted by Fairchild-Hiller and Bell, were selected as finalists by the Army-Navy design competition board. However, the U.S. Army subsequently chose to include Hughes's Model 369 for further consideration as well.
