Ballistic missile submarines (SSBNs) carry submarine-launched ballistic missiles (SLBMs), which are large, long-range missiles armed with multiple nuclear warheads. The SSBNs' basic mission is to remain hidden at sea with their SLBMs, so as to deter a nuclear attack on the United States by another country. Navy SSBNs form one leg of the U.S. strategic nuclear deterrent force, or 'triad,' which also includes land-based intercontinental ballistic missiles (ICBMs) and landbased long-range bombers. The Navy currently operates 14 Ohio (SSBN-726) class SSBNs, the first of which is projected to reach the end of its service life in 2027. The Navy is currently conducting development and design work on a planned class of 12 next generation ballistic missile submarines, or SSBN(X)s, which the service wants to procure as replacements for the 14 Ohio-class boats. The SSBN(X) program, also known as the Ohio-class replacement program, received $497.4 million in research and development funding in the Navy's FY2010 budget, and the Navy's proposed FY2011 budget requests an additional $672.3 million in research and development funding for the program. Navy plans call for procuring the first SSBN(X) in FY2019, with advance procurement funding for the boat beginning in FY2015.
