UH-60 Blackhawk

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 Native American 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.

The UH-60 entered service with the U.S. Army’s 101st Combat Aviation Brigade of the 101st Airborne Division in June 1979.
The U.S. military first used the UH-60 in combat during the invasion of Grenada in 1983, and again in the invasion of Panama in 1989.
During the Gulf War in 1991, the UH-60 participated in the largest air assault mission in U.S. Army history with over 300 helicopters involved. 

Highly modified H-60s were employed during the U.S. Special Operations mission that resulted in the death of Osama bin Laden during Operation Neptune Spear on 1 May 2011.
One such MH-60 helicopter crash-landed during the operation, and was destroyed by the team before it departed in the other MH-60 and a backup MH-47 Chinook with Bin Laden’s remains.
