Navy cruiser grounds on sea trials

The guided-missile cruiser USS Port Royal (CG 73) remained grounded Sunday after a third attempt to refloat it proved unsuccessful.

The 9,600-ton warship ran aground Thursday night in 17 to 22 feet of water about a half mile off Honolulu International Aiport's reef runway.

The Navy plans to try a fourth attempt to free the ship at high tide Monday. Efforts to lighten the ship will include removing the anchor and chains and 800 tons of sea water ballast. If that doesn't work , the Navy will consider dredging a channel behind the ship.

An unsuccessful effort to free the ship Sunday reportedly involved a salvage ship, the USNS Salvor (T-ARS-52), a motor vessel the Dove and four Navy and three commercial tugboats.
