Sub dubbed USS North Carolina

Another Navy vessel is carrying a familiar name. A new nuclear submarine was christened USS North Carolina at a ceremony in Virginia Saturday.

The $2.4 billion sub is the fourth in a new class of submarines designed for the post-Cold War era. It is also the fourth vessel to bear the name North Carolina, and the first since the Battleship North Carolina launched in 1940.

Wilmington Mayor Bill Saffo attended Saturday's christening. He is trying to make Wilmington the new home for the new USS North Carolina. The Navy should receive the submarine by the end of the year.
