Swift said Malaysian authorities had also found a body and were sending it to the US Navy for identification.
The focus of the search for the missing sailors shifted Tuesday to the damaged destroyer's flooded compartments. The USS John S. McCain sustained significant hull damage, resulting in flooding of compartments, including crew berthing, machinery, and communications rooms, the statement added.
Aside from the 10 sailors who went missing, five others were injured.
FOR A state-of-the-art U.S. Navy destroyer to collide with a slow-moving tanker ship, there must be multiple failures of operations and personnel, from the enlisted seamen manning lookout posts to the captain of the ship.
"The divers were able to locate some remains in those sealed compartments during their search today", Swift said.
The Navy has enough assets to make up for the out-of-commision ships, Adm. Harry Harris, head of U.S. Pacific Command, told reporters gathered Tuesday at Osan Air Base, South Korea.
The John S. McCain's sister ship, the Fitzgerald, nearly sank off the coast of Japan after colliding with a Philippine container ship on June 17. On May 9, a collision occurred between the guided-missile cruiser USS Lake Champlain and a South Korean fishing vessel.
Red Cross believes at least 600 missing in deadly Sierra Leone mudslides
Bodies have continued to be retrieved from the mud and rubble, but efforts to identify them are proving hard in the chaos. Almost 400 people are confirmed dead after a mudslide in the Regent area and floods elsewhere in Freetown on Monday.
Reports of the damage to the two ships seem to indicate that they were crossing paths or at least attempting to move in different directions at the time of the collision.
The USS John S. McCain, a guided-missile destroyer, suffered a gash on its port side when it collided with the Liberian registered MV Alnic at 5.30am, some 4.5 nautical miles from the coast in Teluk Ramunia on Monday.
Calling the Navy a "dangerous obstacle" and an "increasing hindrance to ships sailing in Asian waters", it said there was "no denying the fact that the increased activities by United States warships in Asia-Pacific since Washington initiated its rebalancing to the region are making them a growing risk to commercial shipping". "We will continue the SAR operation until there's a determination that the probability of discovering sailors is exhausted".
Swift lauded the "damage control efforts of the crew", such as helping injured sailors and fighting to control the flooding and stability of the ship. Now 10 U.S sailors are missing.
It's the second US warship to be damaged this summer.
US Defense Secretary James Mattis said on Monday that an extensive investigation was underway to "look at all related accidents, incidents at sea". "I'm just ready for answers", she said. The Malaysian Maritime Enforcement Agency said it had deployed more than 500. It's based at the 7th Fleet's homeport of Yokosuka, Japan. "I am also directing a comprehensive review into all potential factors contributing to these incidents". The ship's three senior officers were relieved of their duties after an investigation found the sailors responsible for watching the bridge "lost situational awareness" and that "serious mistakes were made by the crew".
