GREEN VALLEY, AZ (Tucson News Now)
A total of 18 Titan II Missile sites once ringed the city of Tucson and stood in a constant state of readiness as the cold war heated up.
The heavily fortified sites were built in the early 1960s and existed until the early 1980s. Most were located in remote out-of-the-way locations that gave little hint of the potential lethality that resided beneath the surface.
The site in Green Valley, also known as the Titan Missile Museum, was allowed to remain as a museum, and is visited annually by thousands of tourists.
Most however, were destroyed in various ways and filled with concrete. This is all that remains of site 571-4 which is filled with concrete.
These three partially buried structures were once completely buried deep in the ground and connected together in the same way as the museum in Green Valley. The metal dome once covered the site's main control center from which launching would have been initiated.
