The Boeing Vertol YUH-61 (Model 179), a twin turbine-engined, medium-lift, military assault/utility helicopter was the runner-up of a United States Army competition in the mid 1970s to replace the UH-1 Huey family. Though the two final competing designs were both developed to Army specifications, Sikorsky's aircraft was selected.

[edit] History
Under a contract awarded in August 1972, Boeing Vertol designed and delivered three prototypes to compete against the Sikorsky YUH-60A in the US Army's Utility Tactical Transport Aircraft System (UTTAS) program.[1] While Boeing Vertol failed to win the competition, it pinned its hope on winning civil orders and the US Navy's LAMPS III program. In the end, a variant of the Sikorsky design, the SH-60B, would also win, and what civil orders that were received were canceled.[1]
