The missile control center is in the background and the powerhouse is in the foreground (the silo, propellant tanks, and associated buildings are not shown). Eighteen Titan I launch complexes (for 54 missiles) were built in California, Colorado, Idaho, South Dakota, and Washington state at an average cost of $44.4 million apiece (in constant 1996 dollars). Titan I missiles were only on alert from 1962 to 1965.
