Minuteman Missile National Historic Site

During the Cold War, a vast arsenal of nuclear missiles were placed in the Great Plains. Hidden in plain sight, for thirty years 1,000 missiles were kept on constant alert; hundreds remain today. The Minuteman Missile remains an iconic weapon in the American nuclear arsenal. It holds the power to destroy civilization, but is meant as a nuclear deterrent to maintain peace and prevent war.
