| Saturday, May 21, 2011 | 0 comments

The MH-6 Little Bird, and its attack variant, the AH-6, are single-engine light helicopters used for special operations aviation 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. The AH-6j / MH-6j "Little Bird" also known as "The Killer Egg" are light attack/utility helicopters operated by the 160th Special Operations Aviation Regiment. The AH-6 are based around a civilian airframe (MD530F), six-bladed main rotor and four-bladed tail rotor, with extensive modifications in terms of avionics and provisions for the mounting of specialized equipment and weapons systems.

The A/MH-6 was started in 1960, the U.S. 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.
