The Associated Press reports that “the U.S. will keep its current force of 450 land-based nuclear missiles but remove 50 from their launch silos as part of a plan to bring the U.S. into compliance with a 2011 U.S.-Russia arms control treaty, the Pentagon said Tuesday.”  

“The resulting launch-ready total of 400 Minuteman 3 intercontinental ballistic missiles would be the lowest deployed ICBM total since the early 1960s.”  

“The decisions come after a strong push by members of Congress from the states that host missile bases — North Dakota, Wyoming and Montana — to not eliminate any of the silos from which the missiles would be launched.”
