Caution: Use of Deadly Force Authorized
What once was a closely-guarded secret is now shared with visitors. Over a thousand Minuteman Missiles, strategically placed in silos across the Midwest, were manned 24/7, always on alert. These silent sentinels, both revered and resented by locals, are preserved through the Minuteman Missile National Historic Site, which captures their significant history and the mixed emotions surrounding them.
History of the Site
After World War II and the Manhattan Project, the arms race between the US, UK, and the Soviets intensified. Both powers relentlessly developed nuclear capabilities, engaging in espionage and expanding their arsenals under the doctrine of “mutually assured destruction.”
The Nuclear Triad strategy included land-launched nuclear missiles, submarine-launched nuclear missiles, and strategic aircraft. At the height of the Cold War, over 1,000 Minuteman Missiles were ready to launch within 30 minutes, spreading fear of a potential global catastrophe.
Numerous near-misses occurred, like the infamous NORAD “test tape” incident or the heroic refusal of a submariner to launch under mistaken orders. Today, many missile sites have been decommissioned through non-proliferation treaties, with the Delta Facility serving as a grim reminder of those perilous times. Yet, hundreds of missiles remain, posing a chronic concern.
Places to Visit
# Visitor Center Exhibits and Movie
Begin your journey at the Visitor Center, where you can dive deep into Cold War history through captivating exhibits and a film. This spot is perfect for those who lived through the era to reflect and for younger visitors to understand the once-near reality of nuclear conflict.
# Delta-01 Launch Control Facility
This unassuming building housed Missileers and support personnel, featuring a kitchen, entertainment facilities, and an underground alert center. With 8 enlisted personnel above ground and 2 officers below, shifts were grueling—3 days on, 3 days off for the topside crew, and 24-hour shifts for the officers underground.
# Delta-09 Missile Launch Site
Scattered across South Dakota, about 150 missiles stood ever-ready during the Cold War. Delta-09 offers an exclusive peek into a launch silo, once primed for immediate action.
