Page "United States naval reactors" Paragraph 17

Congress has mandated that the U. S. Navy consider nuclear power as an option on all large surface combatants ( cruisers, destroyers ) and amphibious assault ships.

If proven cost-effective in a life cycle cost analysis during the Analysis of Alternatives ( AoA ) phase of preliminary ship design, new ship classes ( e. g. CG ( X )) could proceed with nuclear propulsion.
