Please read Tour Safety Restrictions below: 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. Visit the once secret facilities where Air Force personnel controlled and maintained ten nuclear missiles, part of a force of 150 missiles located in South Dakota. Discover the Cold War events that shaped our lives and still remain through a tour of the underground control center at Delta-01. At the Delta-09 silo, view a nuclear missile which once carried a 1.2 megaton warhead.Plan to visit all three sites Minuteman Missile National Historic Site is located at three sites along a fifteen mile stretch of Interstate 90 in western South Dakota. The Visitor Center is located immediately north of I-90, exit 131. The Launch Control Facility Delta-01 (reservations required) is four miles west and the Delta-09 missile silo self guided tour is 15 miles west of the Visitor Center.

In order to ensure staff availability and the best experience possible, this tour must be reserved at least five days in advance. Standard amenity fees apply and the minimum number of participants on the accessible tour is two visitors.
