U.S. Reducing Naval Firepower Aimed at Qaddafi

Officials say the Pentagon has reduced the amount of naval firepower arrayed against the forces of Libyan strongman Moammar Qaddafi. It's a sign of U.S. confidence that the weeklong assault has tamed Qaddafi's air defenses.

The move, not yet publicly announced, reinforces the White House message of a diminishing U.S. role -- a central point in President Barack Obama's national address Monday night on Libya.

Defense officials say at least one of the five Navy ships and submarines that have launched cruise missiles at Libyan targets from the Mediterranean Sea has left the area. They spoke on condition of anonymity in order to discuss sensitive military movements.
