Situated about half an hours drive south of Tuscon is the Titan Missile Museum. “The only publicly accessible Titan II missile site in the nation.”
All of the other Titan II missile silos have been decommissioned and demolished. Leaving only this site as a historical landmark.
The one hour tour doesn’t really give you much time underground. You only get to see the Launch control room and the second level of the missile silo. However, there are much more in depth tours available. So maybe next time…
