The Sikorsky S-70 is an American medium transport/utility helicopter family manufactured by Sikorsky Aircraft. It was developed for the United States Army in the 1970s, winning a competition to be designated the UH-60 Black Hawk and spawning a large family in U.S. military service. New and improved versions of the UH-60 have been developed since. Civilian versions, and some military versions, are produced under various S-70 model designations.
The S-70 family was developed to meet a United States Army requirement to replace the UH-1 Iroquois family of utility medium-lift helicopters in 1972. Three YUH-60A prototypes were constructed, with the first flying in October 1974. They were evaluated against the Boeing-Vertol YUH-61A. The YUH-60A was selected for production, and entered service as the UH-60A Black Hawk with the U.S. Army in 1979. [2]
After entering service, the helicopter was modified for new missions and roles, including mine laying and medical evacuation.[ citation needed ] An EH-60 variant was developed to conduct electronic warfare and special operations aviation developed the MH-60 variant to support its missions. [3] In the late 1980s the model was upgraded to the UH-60L, which featured more power and lift with the upgrade to the -701C model of the GE T700 engine. The improved UH-60M model was developed in the early 2000s. [2] The UH-60M and its International version, the S-70i, include GPS navigation, a glass cockpit, an integrated Flight Management System, and a significant upgrade to the powertrain and rotor system adding both power and lift capability.[ citation needed ]
The S-70 can perform a variety of missions, including air cavalry, electronic warfare, and aeromedical evacuation. Versions are used to transport the President of the United States under call sign "Marine One". In air assault operations it can move a squad of 11 combat troops and equipment or carry the 105 mm M102 howitzer, thirty rounds of ammunition, and a six-man crew. Alternatively, it can carry 2,600 lb (1,200 kg ) of cargo or sling load 9,000 lb (4,100 kg) of cargo. The S-70 is equipped with advanced avionics and electronics, such as the Global Positioning System.
The United States Navy received the first navalized SH-60B Seahawk in 1983, and the SH-60F Ocean Hawk in 1988.
The HH-60G Pave Hawk is a highly modified version of the S-70 primarily designed to recover downed aircrew or other isolated personnel during war and equipped with a rescue hoist with a 250 ft (76 m) cable that has a 600 lb (270 kg) lift capability, and a retractable in-flight refueling probe. The United States Air Force received the MH-60G Pave Hawk in 1982.
The United States Coast Guard received the HH-60J Jayhawk in 1992. It utilizes the equipment of the HH-60G Pave Hawk on the navalized SH-60 platform. [4]
The S-70A Firehawk is a version of the S-70 designed for firefighting, rescue, medical evacuation, and external lift of bulky cargo and equipment. The Oregon National Guard was the first military organization in the world to add the Firehawk to its inventory; the Los Angeles County Fire Department was the first municipal organization. [ citation needed ] Another Firehawk aerial firefighting operator is the California Department of Forestry and Fire Protection (CAL FIRE) with the S-70i variant. [5]
The Army flies medical evacuation models configured as rotary winged medical suites. It also uses the S-70 for special operations by the 160th Special Operations Aviation Regiment ("Night Stalkers") at Fort Campbell, Kentucky, designated as the MH-60K.[ citation needed ]
The Maple Hawk was a variant offered by Sikorsky to the Canadian Forces during a 1996 tender to replace the military's search and rescue helicopters. [6]
In 2010 August 5, to support its counter-narcotics and armed forces modernisation efforts, the US DSCA approved the Colombian Govt's request of additional 9 UH-60L (4 units allocated to the national police force). [7]
In 2017 March, the National Police of Colombia ordered 10 additional 2nd-hand UH-60A helicopters that will increase their total to 19 helicopters in operation. [8]
In 2018, Poland sign agreement to buy S-70i for Police aviation, to replace Mi-2 reaching the end of their safe flying life. [9]
The company name for the H-60/S-70 family is the S-70 Black Hawk.
