The Boeing Vertol YUH-61 (company designation Model 179) was a twin turbine-engined medium-lift military assault/utility helicopter. The YUH-61 was the runner-up in the United States Army Utility Tactical Transport Aircraft System (UTTAS) competition in the early 1970s to replace the Bell UH-1 Iroquois helicopter. At the end of the flyoff program Sikorsky Aircraft was awarded a contract to develop and build its UH-60A entry.
