Quebec-One Missile Alert Facility

🏆 Cold War Relic — Decommissioned Minuteman missile alert facility — one of the sites that held America’s nuclear arsenal during the Cold War, when Wyoming was the 3rd largest nuclear power on Earth

Quebec-One Missile Alert Facility is a decommissioned Minuteman ICBM (Intercontinental Ballistic Missile) alert facility — part of the 90th Missile Wing based at F.E. Warren Air Force Base in Cheyenne. During the Cold War, Wyoming hosted 200 Minuteman missiles spread across thousands of square miles of rangeland — making Wyoming the 3rd largest nuclear power on Earth if it were an independent country (behind only the US and the Soviet Union!). Each missile carried a nuclear warhead capable of destroying a city. The alert facility housed the two-person crew who would have launched the missiles.

About Quebec-One

Quebec-One Missile Alert Facility near Cheyenne preserves a Peacekeeper (MX) ICBM missile alert facility from the Cold War. Wyoming hosted 50 Peacekeeper missiles — each carrying 10 nuclear warheads — in underground silos across the Cheyenne prairie. The alert facility housed the two-person crew ready to launch on presidential command. This is one of the few publicly accessible Cold War nuclear missile sites in the United States.

Things to Do

Touring the preserved missile alert facility, viewing the launch control equipment, learning about Cold War nuclear deterrence, and reflecting on the nuclear weapons that sat beneath the Wyoming prairie for decades.

Insider Tips

Cold War relic: Quebec-01 was a Peacekeeper (MX) missile alert facility — one of 50 launch control centers across Wyoming that controlled nuclear ICBMs. Pro tip: Wyoming hosted 200 Minuteman and Peacekeeper missiles during the Cold War — enough nuclear firepower to destroy a continent. Strategic location: Wyoming’s sparse population and distance from coasts made it ideal for dispersing nuclear missiles.

Best Time to Visit

Summer: Best access. Year-round: Exterior visible. Fall: Quiet prairie setting. Spring: Green backdrop.

Frequently Asked Questions

Why were missiles in Wyoming?

Wyoming’s sparse population, flat terrain, and central location made it ideal for ICBM deployment — missiles needed to be dispersed across large areas to prevent a single enemy strike from destroying them all. At peak deployment, 200 missiles sat in underground silos across eastern Wyoming. Launch crews operated in underground capsules, on 24-hour alert. Wyoming currently hosts 150 Minuteman III missiles — still on alert.

Make it a road trip: Pair a visit with Register Cliff (a short drive away) or Oregon Trail Ruts (a short drive away).
