Sikorsky UH-60 Blackhawk helicopter model. The Sikorsky S-70 UH-60 Black Hawk is a light transport helicopter that performs many missions in the Army. The Black Hawk is the primary helicopter for air assault, air cavalry, and aeromedical evacuation units. Modified Black Hawks also fulfill command and control, electronic warfare, and special operations roles. The Black Hawk has enhanced the overall mobility of the Army because of its dramatic improvements in troop capacity and cargo lift capability compared to the UH-1 "Huey" it replaces. Now, an entire 11-man, fully equipped infantry squad can be lifted in one Black Hawk, and the troops can be transported faster and in most weather conditions. The Black Hawk also is the first utility and assault helicopter that adds to the Army's division-level mobility. For example, it can reposition a 105mm howitzer, its crew of six, and up to 30 rounds of ammunition in a single lift.
