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 land-based 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. The Navy preliminarily estimates the procurement cost of each SSBN(X) at $6 billion to $7 billion in FY2010 dollars -- a figure equivalent to roughly one-half of the Navy's budget each year for procuring new ships. Some observers are concerned that procuring 12 SSBN(X)s during the 15-year period FY2019-FY2033, as called for in Navy plans, could lead to reductions in procurement rates for other types of Navy ships during those years. This report provides background information on the SSBN(X) program and potential FY2011 issues for Congress to consider.
