Navy officials said Tuesday some remains have been found. They are still working to recover the body and transfer them to the U.S. Navy for identification. The collision tore a gaping hole in the McCain's left rear hull and flooded adjacent compartments including crew berths and machinery and communication rooms.
This was the Navy's fourth accident in Asia this year, and the second fatal collision in the past two months.
That accident followed the destroyer USS Fitzgerald's June 17 collision with another commercial ship, killing seven sailors.
Military experts say the Navy's training is now being called into question, and a shakeup in leadership may be next.
The US Navy has fired one of its highest-ranking admirals because of a string of embarrassing and unsafe gaffes, the latest a collision near Singapore that left 10 sailors missing and increasingly presumed to be dead.
Earlier on Thursday, the US Navy reported that five injured sailors of the warship have been discharged from hospital to return to the command.
The U.S. 7th Fleet is based in Yokosuka, Japan, and at any given time includes between 50 and 70 ships and submarines, as well as 140 aircraft and roughly 20,000 sailors, according to the fleet's webpage.
Adm. Scott Swift said the bodies on the ship were discovered by divers performing recovery operations inside.
Ten American U.S. Navy Sailors were reported missing after the collision.
The Navy said last week the Fitzgerald's commanding officer, the ship's executive officer and the senior enlisted sailor on the ship all had been relieved of their command.
He said early investigations don't show that a cyberattack might've caused the ship to collide with the tanker. That collision resulted in the deaths of seven United States sailors.
