LGM-30 Minuteman
The LGM-30 Minuteman is a US land-based intercontinental ballistic missile (ICBM), in service with the Air Force Global Strike Command. As of 2014, the LGM-30G Minuteman III version is the only land-based ICBM in service in the United States. It is one component of the US nuclear triad—the other two parts of the triad being the Trident submarine-launched ballistic missile (SLBM), and nuclear weapons carried by long-range strategic bombers. Each missile can carry up to three nuclear warheads, which have a yield in the range of 300 to 500 kilotons. The Minuteman was the first MIRV-capable missile.
The name "Minuteman" comes from the Revolutionary War's Minutemen. It also refers to its quick reaction time; the missile can be launched within minutes after the receipt of a valid launch order.〔.〕〔.〕 The Air Force plans to keep the missile in service until at least 2030.
The current US force consists of 450 Minuteman-III missiles〔Norris, R. S. and H. M. Kristensen (U.S. nuclear forces, 2009 ) (''Bulletin of the Atomic Scientists'' ) March/April 2009〕 in missile silos around Malmstrom AFB, Montana; Minot AFB, North Dakota; and F.E. Warren AFB, Wyoming.〔 By 2018 this will be reduced to 400 armed missiles, with 50 unarmed missiles in reserve, and four non-deployed test launchers to comply with the New START treaty.
