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.

Tour Safety Restrictions
The Delta-01 tour is moderately strenuous and requires a quarter mile round trip walk to and from the Delta-01 compound. All tour participants must be able to climb two 15 foot ladders, walk, and stand unassisted. Visitors who wish to participate in the underground part of the tour must fulfill the following requirements:
- Be physically capable of climbing two 15 foot ladders unassisted. These ladders are permanently attached to the wall and are very sturdy.
- Children must be at least 40” tall, six years of age, and be able to climb the ladder unassisted. At least one adult must accompany child on Delta-01 Tour.
- Be comfortable in a small elevator in close proximity to six other adults.
- Be comfortable with heights of approximately 35 feet or about 3 stories. The elevator door is an open grate, not a solid door.
- The underground control center was not designed to accommodate the general public. It is accessed by an elevator and a ladder. In the event of an elevator failure, visitors that are underground will need to be capable of climbing the ladder for a safe and timely exit. Entering the control center also requires passing through a narrow corridor.
- Why only six per tour? Because the facility was built for nuclear war. A small elevator and tight space.
- Arrive 15 minutes early tour time to ensure you have time to walk from the parking lot to the front gate at Delta-01, where all tours start.
