Mabus names next-generation ballistic sub class

Navy Secretary Ray Mabus will officially name the Ohio-class Replacement Submarine the Columbia-class today during a ceremony at the District of Columbia City Hall.

The Columbia-class is the Navy's next-generation ballistic missile submarine that will replace the legacy Ohio-class sub fleet. The first-in-class boat is the Columbia (SSBN-826), according to the service.

This is the first time the name has been used to recognize the U.S. capital.
