History of the Hughes OH-6 Cayuse Helicopter
The inception of the OH-6 Cayuse traces back to the U.S. Army LOH (Light Observation Helicopter) competition in 1963. From its initial identity as the Hughes Model 369, it contended against 12 other designs. The spotlight ultimately centered on three: Hughes’ Model 369, Fairchild-Hillier’s H23 Raven, and Bell’s early OH-58 Kiowa model.
While Bell’s offering fell short due to its underwhelming power, the Hughes Model 369 – rebranded YOH-6A with a robust 252hp Allison T63-A-5A engine – soared during the trials at Fort Rucker, Alabama in 1963.
