Damage to the container ship ACX Crystal after colliding with the USS Fitzgerald.

The mother of a U.S. Navy sailor said her son kept diving to try to save his shipmates after a collision at sea until their flooded sleeping berth began running out of air pockets, while other survivors — believing their ship was under attack — hurried to man the guns.

Mia Sykes of Raleigh, North Carolina, told The Associated Press on Sunday that her 19-year-old son, Brayden Harden, was knocked out of his bunk by the impact, and water immediately began filling the berth, after their destroyer, the USS Fitzgerald, collided with a Philippine-flagged container ship four times its size off the Japanese coast.

The ships collided about 2:20 a.m. Saturday, when the Navy said most of the 300 sailors on board would have been sleeping, and authorities have declined to speculate on a cause while the crash remains under investigation.

On Monday morning in Japan, the Navy's 7th Fleet identified the seven sailors who died. Navy divers had recovered the bodies after the severely damaged Fitzgerald returned to the fleet's home in Yokosuka, Japan, on Saturday with assistance from tug boats.

Vice Adm. Joseph Aucoin, the commander of the 7th Fleet, described a harrowing scene as other sailors fought to keep the ship from sinking. Most of the damage is below the waterline, including a large gash near the keel, Aucoin said.

"The water flow was tremendous, and so there wasn't a lot of time in those spaces that were open to the sea. And as you can see now, the ship is still listing, so they had to fight the ship to keep it above the surface. It was traumatic," Aucoin said at a news conference at the Yokosuka base on Sunday.
