The decommissioned silo is located at F.E. Warren Air Force Base in Cheyenne. The decommissioning is a key step in the Air Force’s plan to modernize the land-based portion of America’s nuclear arsenal, the so-called nuclear triad that also includes air and sea. As part of the modernization project, all MIII missiles will be replaced with a modernized missile, the LGM-35A Sentinel, which is being led by prime contractor Northrop Grumman.
