Just south of Tucson, Arizona in Green Valley is the last remaining missile silo for the Titan II missile, the largest nuclear ICBM ever deployed by the United States. There were once 54 of these silos around the country, with the sole purpose of mutually assured destruction in the event the country was ever attacked by nuclear weapons.Now, this silo and it’s command bunker have been turned into the Titan II Missile Museum, and visitors can visit the once top secret command bunker and silo.Because of arms treaties, the missile silo doors are locked in a state of being half open, to show any satellites passing overhead that the silo is not operational. The open silo gives us a rare chance to look inside, to see a place that could have helped bring about the end of the world as we know it.This missile silo was in operation from 1963 to 1984, and visiting is like taking a step back in time. In this video we walk around the outside of the silo before taking a tour of the command bunker (including a rare look at the living quarters) and the missile silo.The Titan II Missile Museum is located at 1580 W Duval Mine Rd, Green Valley, AZ 85614
