The Sikorsky UH-60 Black Hawk is a
four-bladed, twin-engine, medium-lift utility helicopter manufactured by Sikorsky
Aircraft. Sikorsky submitted the S-70 design for the United States Army's
Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The
Army designated the prototype as the YUH-60A and selected the Black Hawk
as the winner of the program in 1976, after a fly-off competition with the Boeing
Vertol YUH-61.
Named after the Indian war leader Black Hawk, the
UH-60A entered service with the U.S. Army in 1979, to replace the Bell UH-1
Iroquois as the Army's tactical transport helicopter. This was followed by the
fielding of electronic warfare and special operations variants of the Black
Hawk. Improved UH-60L and UH-60M utility variants have also been developed.
Modified versions have also been developed for the U.S. Navy, Air Force, and Coast
Guard. In addition to U.S. Army use, the UH-60 family has been exported to
several nations. Black Hawks have served in combat during conflicts in Grenada,
Panama, Iraq, Somalia, the Balkans, Afghanistan, and other areas in the Middle
East.
