The Navy is currently developing technologies and studying design options for a planned new cruiser called the CG(X). The Navy wants to procure 19 CG(X)s as replacements for its 22 existing Ticonderoga (CG-47) class Aegis cruisers. The Navy wants the CG(X) to be a highly capable multimission ship with an emphasis on air defense and ballistic missile defense (BMD). The Navy has not yet announced a preferred design concept for the CG(X). Observers were expecting the Navy to announce a preferred design concept in late 2007/early 2008, but such an announcement is now expected to occur no earlier than late 2008/early 2009. The Navy originally intended to use the design of its new DDG- 1000 destroyer as the basis for the CG(X) design, but it is no longer clear that this is still the Navy's preferred approach. Although the Navy's FY2009 budget calls for procuring the first CG(X) in FY2011, press reports state that the Navy may defer the scheduled procurement of the first ship to FY2015 or later. Section 1012 of the FY2008 defense authorization act (H.R. 4986/P.L. 110- 181 of January 28, 2008) makes it U.S. policy to construct the major combatant ships of the Navy, including the CG(X), with integrated nuclear power systems, unless the Secretary of Defense submits a notification to Congress that the inclusion of an integrated nuclear power system is not in the national interest. The Navy has studied nuclear power as a design option for the CG(X), but has not yet announced whether it would prefer to build the CG(X) as a nuclear-powered ship. Procurement of a nuclear-powered CG(X) in FY2011 would, under normal budgeting practices, involve funding the ship's long-leadtime nuclear-propulsion components in FY2009. The Navy's proposed FY2009 budget requests $370 million for research and development work on the CG(X). The Navy's proposed FY2009 budget does not request any advance procurement funding for the first CG(X).
