The competition to win the contract would come down to the Boeing-Vertol YUH-61A and the Sikorsky UH-60, with the Sikorsky winning after a series of tests in the hands of US Army pilots. Sikorsky developed the prototypes of the UH-60 Black Hawk to meet the US Army requirements for a new Utility Tactical Transport Aircraft System (UTTAS) to replace the Huey and they specified that the engine used would be the General Electric T700 turbine. The Huey had made a name for itself during the Vietnam conflict and any replacement for it was going to have its work cut out measuring up to one of the most beloved military choppers of its time. The Sikorsky UH-60 Black Hawk was developed in the early 1970s as a replacement for the legendary Huey, officially called the Bell UH-1 Iroquois.
