Warning… Use of Deadly Force Authorized…
It Was Once Classified…
The Minuteman Missiles, more than 1,000 of them, were hidden in silos across the Midwest. They were always on alert, manned 24/7. The local residents harbored mixed feelings about these silent guardians—sometimes loving and hating them simultaneously. The Minuteman Missile National Historic Site preserves this complex history and sentiment.
History of the Site
Post-World War II and following the Manhattan Project, tensions escalated between the US, UK, and the Soviets. Both superpowers raced to enhance their nuclear capabilities. Through espionage and research, the Soviets also developed a nuclear bomb, sparking an arms race that threatened global peace with the principle of “mutually assured destruction.” The Nuclear Triad, comprising land-launched nuclear missiles, nuclear-armed submarines, and strategic aircraft, played a central role. At their peak, over 1,000 land-based missiles were stationed across the Midwest, ready to strike within 30 minutes. There were multiple close calls, like a mishandled “test tape” at NORAD or a submarine commander’s disobedience that nearly triggered global catastrophe.
Various treaties for nuclear non-proliferation have since decommissioned many of these sites, including the Delta Facility. Yet, hundreds of missiles remain, standing watch and casting a shadow over the potential for accidental nuclear disaster.
Places to Visit
Exhibits and Movie
Your first stop at the Minuteman Missile National Historic Site should be the Visitor Center. The engaging exhibits focus on the Cold War and the missiles themselves. For those who remember the Cold War, the concern over nuclear war will be familiar—and it’s a concern that has resurfaced in recent times.
Delta-01 Launch Control Facility
Hidden in plain sight, this facility housed the Missileers and support staff. Equipped with a kitchen, entertainment facilities, and an underground alert site, it was manned by eight enlisted personnel topside and two officers underground at all times. Personnel worked in 24-hour shifts, providing continuous vigilance.
Delta-09 Missile Launch Site
Unlike the Peacekeeper missiles that needed co-location, Minuteman missiles could be spread miles apart. During the Cold War, 150 of these missiles dotted South Dakota, always ready to launch. Visiting Delta-09 offers a rare glimpse into a working missile silo.

What’s it Like to Visit?
Regardless of your views on nuclear weapons, the Cold War, or missiles, the Minuteman Missile National Historic Site offers a fascinating historical perspective. On my tour, we had the privilege of meeting former Missileers who provided unique insights.
Seeing how they passed the time—playing board games, watching TV, and pursuing advanced degrees—added a human element to life inside the silos. The cramped quarters, military humor, and signatures of past personnel all lent authenticity to the experience.
