Sikorsky S-70 is an American medium transport/utility helicopter
family manufactured by Sikorsky Aircraft. It was developed for the
U.S. Army in the 1970s, winning a competition to be designated the
UH-60 Black Hawk
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
US Army requirement to replace
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
US Army in 1979.
After entering service, the helicopter was modified for new missions
and roles, including mine laying and medical evacuation.[citation

and special operations aviation developed the MH-60 variant to support
its missions. 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. 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
The S-70 can perform a wide array of missions, including air cavalry,
electronic warfare, and aeromedical evacuation: several versions are
used to transport the President of the United States, which while
carrying the President is known as "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.

primarily designed to recover downed aircrew or other isolated

The Maple Hawk was a variant offered by Sikorsky to the Canadian
Forces during[when?] the tender to replace the military's search and

the Air Force MH-60G Pave Hawk was $10.2 million.
