In its brief career, a total of six USAF squadrons were equipped with the Titan I missile. Each squadron was deployed in a 3x3 configuration, which meant each squadron controlled a total of nine missiles divided among three launch sites, with the six operational units spread across the western United States in five states: Colorado (with two squadrons, both east of Denver), Idaho, California, Washington and South Dakota. Each missile complex had three Titan I ICBM missiles ready to launch at any given time.
