The Sikorsky UH-60 Black Hawk is a medium-lift utility or assault helicopter derived from the twin-turboshaft engine, single rotor Sikorsky S-70.

The YUH-60A (S-70) was the winner of the United States Army Utility Tactical Transport Aircraft System (UTTAS) competition in the early 1970s to replace the UH-1 Iroquois (Huey) family. It would go on to serve as the basis for variants in service with other branches of the US military.


The Black Hawk was developed to meet a US Army Utility Tactical Transport Aircraft System (UTTAS) requirement for a UH-1 Iroquois replacement released in January 1972. [Leoni 2007, p. 39.] Four prototypes were constructed, the first (YUH-60) flying in October 1974, and evaluated against a rival Boeing-Vertol design, the YUH-61A. A Preliminary Evaluation was conducted in November 1975 prior to delivery of the prototypes to the US Army. The evaluation was conducted to determine if the aircraft could be operated safely by typical Army pilots. Three of the prototypes were delivered to the US Army in March 1976, and one was kept by Sikorsky for internal research. The Black Hawk was selected for production in December 1976. Deliveries of the UH-60A to the US Army began in October 1978 and the helicopter entered service in June 1979.Eden, Paul. "Sikorsky H-60 Black Hawk/Seahawk", "Encyclopedia of Modern Military Aircraft". Amber Books, 2004. ISBN 1904687849.]

In the late 1980s, the model was upgraded to the UH-60L (first production aircraft 89-26179) which featured more power and lift with the upgrade to the -701C model of the GE engine. The current production model (UH-60M) will extend the service life of the UH-60 design well into the 2020s, features still more power and lift and state of the art electronic instrumentation, flight controls and aircraft navigation control.


The Black Hawk series of aircraft can perform a wide array of missions, including the tactical transport of troops, electronic warfare, and aeromedical evacuation. A VIP version known as the VH-60N is used to transport important government officials (e.g., Congress, Executive departments) with the helicopter's call sign of "Marine One" when transporting the President of the United States. [ [http://www.globalsecurity.org/military/systems/aircraft/vh-60.htm VH-60] , Global Security] In air assault operations it can move a squad of 11 combat troops with equipment or reposition the 105 mm M102 howitzer with thirty rounds of 105 mm ammunition, and a four-man crew in a single lift. Alternatively, it can carry 2,600 lb (1,170 kg) of cargo or sling load 9,000 lb (4,050 kg) of cargo. The Black Hawk is equipped with advanced avionics and electronics for increased survivability and capability, such as the Global Positioning System.

The UH-60 can be equipped with stub wings at top of fuselage to carry fuel tanks or possibly armament. The initial stub wing system is called external stores support system (ESSS). It has two pylons on each wing to carry two 230 gal and two 450 gal tanks in total. The ESSS can also carry 10,000 lb of armament such as rockets, missile and gun pods. The ESSS entered service in 1986. However it was found that with four fuel tanks it would obstruct the firing field of the door guns. The external tank system (ETS) with unswept stub wings to carry two fuel tanks was developed to alleviate the issue.Bishop, Chris. "Sikorsky UH-60 Black Hawk". Osprey, 2008. ISBN 978-1-84176852-6.]

The unit cost varies with the version due to the varying specifications, equipment and quantities. For example, the unit cost of the Army's UH-60L Black Hawk is $5.9 million while the unit cost of the Air Force MH-60G Pave Hawk is $10.2 million. [ [http://www.globalsecurity.org/military/systems/aircraft/h-60.htm H-60] , Global Security]

Operational history

The UH-60 entered service with the US Army's 101st Airborne Division in June 1979. [http://www.vectorsite.net/avs70_1.html Sikorsky S-70 Black Hawk] , Vectorsite.net, 1 July 2006.] The UH-60 its first combat service in the US invasion of Grenada in 1983. UH-60As also served in the invasion of Panama in 1989. UH-60A and UH-60L Black Hawks participated in the Gulf War of 1991. Black Hawks saw action in Somilia, Haiti, and the Balkans in the 1990s. UH-60s continue to serve in Afghanistan and Iraq.


The UH-60 comes in many variants, and many different modifications. The standard U.S. Army version can be fitted with the "External Stores Support System" (ESSS) [ [http://www.sikorsky.com/details/0,,CLI1_DIV69_ETI561,00.html Sikorsky Aircraft Corporation ] ] which provides wings that allow it to carry up to four external fuel tanks for extended range operations or a variety of weapons, [ [http://www.army-technology.com/projects/black_hawk/ Army Technology - UH-60 Black Hawk Sikorsky S-70A - Multi-Mission Helicopter ] ] while variants may have different capabilities and their respective equipment in order to fulfill different roles.
