Minuteman III: One Hundred Fifty Missiles Under the Prairie

The most consequential military infrastructure in the region is almost entirely invisible. Spread across roughly eighty-five hundred square miles of North Dakota centered on Minot Air Force Base, up to one hundred and fifty Minuteman Third intercontinental ballistic missiles sit in hardened concrete silos buried beneath farm fields. Each missile carries a warhead capable of destroying a city. The ninety-first Missile Wing, headquartered at Minot, operates all of them.

The Minuteman program was conceived in the late nineteen fifties as a response to a specific fear: that Soviet bombers or missiles could destroy American bomber bases before they could get airborne, leaving the United States with no ability to strike back. Fixed underground silos, dispersed across hundreds of miles, were designed to survive a first strike. Even if an enemy destroyed ninety percent of the silos, the remaining ten percent could still inflict catastrophic damage, which meant any rational adversary would be deterred from striking in the first place. This logic, called mutual assured destruction, has governed nuclear strategy for more than six decades.

The missile crews who operate the system work in two-person teams in underground launch control capsules, on twenty-four-hour shifts, carrying out a job that requires absolute procedural discipline and the psychological ability to function in conditions of profound isolation and consequence. The capsule is designed to survive a nearby nuclear blast, kept habitable by massive shock absorbers. A launch crew would never meet the people their missiles were aimed at. That is the nature of deterrence.

Today the Minuteman Third is the sole land-based ballistic missile in the American arsenal. Minot's missiles are a legacy of the Cold War that has not ended, merely quieted, still armed, still ready, still pointed at targets their crews never see.
