MD Helicopters MH-6 Little Bird

The Boeing MH-6M Little Bird (nicknamed the Killer Egg) and its attack variant, the AH-6, are light helicopters used for special operations in the United States Army. Originally based on a modified OH-6A, it was later based on the MD 500E, with a single five-bladed main rotor. The newest version, the MH-6M, is based on the MD 530F and has a single, six-bladed main rotor and four-bladed tail rotor.

The OH-6 was started in 1960, when the US Army issued Technical Specification 153 for a Light Observation Helicopter (LOH) that could perform personnel transport, escort and attack missions, casualty evacuation, and observation. Twelve companies took part in the competition and Hughes Tool Company's Aircraft Division submitted the Model 369. Two designs, those submitted by Fairchild-Hiller and Bell, were selected as finalists by the Army-Navy design competition board, but the Army later included the helicopter from Hughes as well.[citation needed]

The first Model 369 prototype flew on 27 February 1963. Originally designated the YHO-6A under the army's designation system, the aircraft was redesignated the YOH-6A under the Department of Defense's new joint system in 1962. Five prototypes were built, each fitted with a 252 shp (188 kW) Allison T63-A-5A engine, and delivered to the US Army at Fort Novosel, Alabama to compete against the other 10 prototype aircraft submitted by Bell and Fairchild-Hiller. In the end, Hughes won the competition and the Army awarded a contract for production in May 1965. The initial order was for 714 aircraft, but that was later increased to 1,300 with an option to buy another 114. Seventy helicopters were built in the first month.[citation needed]

This agile, unarmed helicopter is outfitted with outboard "benches" designed to ferry up to 3 operators on each side. There is also a gunship variant, the AH-6. Painted black for nighttime operations, this small aircraft can conduct rapid insertions and extractions of special operations forces into areas its larger counterpart, the MH-60 Black Hawk can't.[citation needed]

After the April 1980 failure of Operation Eagle Claw, in which Marine pilots and Navy helicopters were used, it was determined that the US Army lacked aircraft and crews who were trained and prepared to perform special operations missions. To remedy this shortcoming, the Army began developing a special aviation task force to prepare for the next attempt to rescue the hostages: Operation Credible Sport.

The United States Army 160th Special Operations Aviation Regiment (Airborne), also known as Night Stalkers, is a special operations force that provides helicopter aviation support for general purpose forces and special operations forces. Its missions have included attack, assault, and reconnaissance, and are usually conducted at night, at high speeds, low altitudes, and on short notice.

The architects of the task force identified the need for a small helicopter that could land in the most restrictive locations and could be easily transported on Air Force airlifters. They chose the OH-6A scout helicopter, and it became known as the Little Bird compared to the other aircraft in the task force, the UH-60A and the CH-47C. As a separate part of the project, armed OH-6As were being developed at Fort Novosel, Alabama.

The pilots selected to fly the OH-6A helicopters came from the 229th Attack Helicopter Battalion and were sent to the Mississippi Army National Guard's Army Aviation Support Facility (AASF) at Gulfport, Mississippi, for two weeks of qualification training in the aircraft. When the training was completed, C-141 aircraft transported the aircraft and crews to Fort Huachuca, Arizona, for two weeks of mission training. The mission training consisted of loading onto C-130 transport aircraft which would then transport them to forward staging areas over routes as long as 1,000 nautical miles (1,900 km). The armed OH-6 aircraft from Fort Novosel joined the training program in the fall of 1980.
