The Navy will confirm little about the CG(X) program, but analysts say the ship's job will be to protect a fleet from aerial and missile attack. At least two versions of this ship are being considered. The first could use the same hull as the DDG 1000, replacing one of that ship's guns with additional missile cells and upgrading to a radar system optimized for missile defense. The second could be a larger (23,000 tons instead of 14,500), nuclear-powered ship designed for ballistic-missile defense. Robert Work says that yet another version could provide ballistic-missile defense to the U.S. mainland.
Replaces: The planned CG(X) will replace the Navy's aging fleet of Ticonderoga-class guided missile cruisers.
Status: The Navy plans to order the first CG(X), whatever its final form turns out to be, in 2011. From there, analysts expect the Navy to build up to a fleet of 19 CG(X)s by 2030.
Prognosis: The fate and eventual configuration of the CG(X) depends on the success of the DDG 1000, as well as on the choice of propulsion.
