    3. 3 Role and Mission The OH-6A aircraft was designed primarily as a Light Observation Helicopter (LOH, hence the nickname LOacH) to locate enemy positions by dropping smoke grenades and provide logistical assistance to other aircraft for strafing/bombing missions. This was an extremely dangerous mission that required the Cayuse to expose itself to small arms fire from the enemy. In fact, it was common for the Cobra and Huey gun ships to locate the enemy by sighting the wreckage of the Cayuse. Pilots overwhelmingly preferred the OH-6A due to its crash survivability. Of the 1,442 OH-6A's built between 1967 and 1972, approximately 50 are still flying with law enforcement agencies.

    9. 9 Dr. Baron Smith created this “nose art” in 1996 to give the aircraft an identity for marketing and advertising purposes. The Army ceased using “nose art” in 1972.

    11. 11 Hughes OH-6A Cayuse “Charlie Chopper” 68-17357 Prototype And Culver City Production Line

    12. 12 This is the earliest known artist’s drawing of the proposed OH-6A, probably circa 1961. This picture came from an original 8”x10” negative from the Hughes archives found by Baron Smith in 1993.

    13. 13 This is the original prototype YOH-6 flying in Culver City, Ca. in 1963. Note similarities to TH-55 (269 series) such as canted stab and TH-55 nose glass (“birdcage”).

    14. 14 Prototype YOH-6A hovering with Jeep, circa 1964.

    15. 15 A very early mock-up, non-flying prototype of the future OH-6A.

    17. 17 View of the Culver City OH-6A assembly line in Building 15, the same building as the Howard Hughes “Spruce Goose” flying boat project in 1946. Note the rotor blade fairings which were used on only the first 40 units, being deemed as unnecessary for aerodynamics, and the 8-piece glass.

    18. 18 Another view of the Culver City assembly line. Circa 1969. At one time, this building was the world’s largest wooden hangar! The rotor head assembly was found less than 50 feet from this camera vantage point!
