SEOUL, Dec. 1 (Xinhua) -- South Korean and U.S. forces wrapped up Wednesday their four-day joint naval drills in the Yellow Sea.

On the last day of the exercises, the allies conducted a mock drill aimed at providing warships on operations with military supplies and materials.

They previously staged maritime interdiction drills designed to stem the spread of weapons of mass destruction under the U.S.-led anti-proliferation campaign, anti-aircraft defense drills and maritime defensive and offensive exercises.

The joint maneuver mobilized some 7,300 troops, the 97,000-ton aircraft carrier George Washington and about ten navy ships.
