After working alongside craftsmen from the Puget Sound Naval Shipyard and Ship Repair Facility Yokosuka to complete routine maintenance to the Nimitz-class aircraft carrier, Sailors will now put the ship through a series of tests before going underway. George Washington sailed from its Truman Bay pier into open waters to begin a certification process that will ensure the ship, its equipment and crew are ready for extended periods at sea. "We're ready to execute sea trials," said Capt. David A. Lausman, George Washington's commanding officer.
