The U.S. Navy’s guided missile cruiser USS Antietam ran aground off the coast of Yokosuka, Japan on Tuesday, damaging the ship’s propeller and causing hydraulic oil to spill into the water.
The ship grounded after dragging anchor in high winds near its home port of Yokosuka. The grounding caused the ship to dump some 1,100 gallons of oil into the water, officials said.
The extent of the damage and grounding is unclear, but the U.S. Navy did confirm that the ship damaged during anchoring.

“The ship safely returned to Fleet Activities Yokosuka with the help of tugs. There were no injuries to U.S. or Japanese personnel. The incident did result in the discharge of hydraulic oil into the water,” the Navy said.
“The Navy is cooperating with the Government of Japan and Japanese Coast Guard in response to this issue and is taking appropriate measures to minimize impacts to the environment,” the statement added.
