The UH-60 Blackhawk or Sikorsky S-70 is a U.S medium transport/utility helicopter built by Sikorsky Aircraft. It was designed for the United States Army during the 1970s and won in a competition that led to its designation “UH-60 Black Hawk” and created a vast family in the military service of the United States.
The helicopter was built in several improved variants since then. The H-60 series is greatly used by the Department of Defense and is equipped to fulfill a wide range of roles such as air cavalry, electronic warfare, search and rescue, aeromedical evacuation, and other special missions.
Some aircraft are used for the transport of the United States President as Marine One. The VH-60N is an executive transport helicopter based on the UH-60 Black Hawk and the United States Navy’s SH-60 Seahawk aircraft. In 1989, it was initially delivered to HMX-1 to replace the VH-1N.
