The UH-60 Blackhawk is a four-bladed, twin-engine utility helicopter produced by Sikorsky Aircraft. It was first introduced in 1979 and continues to be a staple in the United States Army. The Blackhawk was first used in combat during the invasion of Grenada. Later the Blackhawk was part of the largest air assault mission in U.S. Army history during the Gulf War. Then the UH-60 conducted many air assault and support missions during the invasion of Iraq in 2003. The Blackhawk is one of the most well-known helicopters in the U.S. Army because of the blockbuster film “Black Hawk Down” that illustrated the assault on Mogadishu in Somalia and the use in the mission that resulted in the death of Osama bin Laden.
