U.S. Strategic Nuclear Forces: Background, Developments, and Issues [January 14, 2013] [open pdf - 473KB]
"During the first Obama Administration, Congress reviewed the 2010 Nuclear Posture Review, the 2012 New START [Strategic Arms Reduction Treaty] Treaty, and funding plans for the U.S. nuclear enterprise. Specifically, even though the United States plans to reduce the number of warheads deployed on its long-range missiles and bombers, consistent with the terms of the New START Treaty, it also plans to develop new delivery systems for deployment over the next 20-30 years. The 113th Congress will continue to review these programs during the annual authorization and appropriations process. During the Cold War, the U.S. nuclear arsenal contained many types of delivery vehicles for nuclear weapons. The longer-range systems, which included long-range missiles based on U.S. territory, long-range missiles based on submarines, and heavy bombers that could threaten Soviet targets from their bases in the United States, are known as strategic nuclear delivery vehicles. At the end of the Cold War, in 1991, the United States deployed more than 10,000 warheads on these delivery vehicles. That number has declined to less than 6,000 warheads today, and is slated to decline to 1,550 warheads by the year 2017 if the New START Treaty enters into force. […] The Obama Administration is completing a review of the size and structure of the U.S. nuclear force, and a review of U.S. nuclear employment policy, as it implements the 2010 Nuclear Posture Review. It is also implementing the New START Treaty with Russia that will limit the number of deployed missiles and warheads in the U.S. strategic force. Congress will review the Administration's plans for U.S. strategic nuclear forces during the annual authorization and appropriations process, and as it assesses U.S. plans under New START and possible future arms control treaties with Russia. This report will be updated as needed."
