Ten sailors are missing after a U.S. warship collided with an oil tanker east of Singapore before dawn on Monday, tearing a hole beneath the waterline and flooding compartments that include a crew sleeping area, the U.S. Navy said.
The collision between the guided-missile destroyer USS John S. McCain and the tanker Alnic MC was the second involving a U.S. Navy destroyer and a merchant vessels in Asian waters in little more than two months.
The ships collided while the U.S. warship was heading to Singapore for a routine port call, the Navy said in a statement.
“Initial reports indicate John S. McCain sustained damage to her port side aft,” the Navy said. “There are currently 10 sailors missing and five injured.”
The destroyer had made its way to Singapore’s Changi Naval Base by Monday afternoon under its own power.
Significant damage to the hull had resulted in flooding to compartments, including crew berthing, machinery, and communications rooms, the Navy said, but crew members were able to stop the flooding.
Four of the injured were taken by helicopter to hospital in Singapore with non-life threatening injuries. The fifth needed no further treatment.
The USS John S. McCain’s sister ship, the USS Fitzgerald, almost sank off the coast of Japan after it was struck by a Philippine container ship on June 17. The bodies of seven USS Fitzgerald sailors were found in a flooded berthing area.
Collisions between warships and other large vessels are extremely rare, with naval historians going back more than 50 years to find a similar incident.
