Seven American sailors are missing and an unspecified number are injured after the guided missile destroyer Fitzgerald collided with a merchant vessel off Japan's coast in the Philippine Sea.
Its commanding officer, Cmdr. Bryce Benson, was medically evacuated from the ship Saturday morning local time. He was transferred to U.S. Naval Hospital Yokosuka and is reportedly in stable condition, a Navy release said.
The Fitzgerald's executive officer, Cmdr. Sean Babbitt, assumed command once Benson was deemed incapacitated.
A second medical evacuation was also being arranged, the Navy said.
As of 9 a.m. local time, the Fitzgerald's crew was still fighting to control damage to the ship as it limped backed to land, three sources with knowledge the incident told Navy Times.
The incident occurred around 2:30 a.m. about 50 nautical miles southwest of Yokosuka, Japan. The Fitzgerald suffered extensive damage above and beneath the waterline when, according to U.S. officials, it struck the Philippine-flagged merchant vessel ACX Crystal, a ship that displaces nearly 40,000 tons and is roughly the size of an amphibious assault ship such as the Wasp or Iwo Jima. That's more than four times the size of Fitzgerald.
Initial reports suggested that Auxiliary Machine Room 1 and two crew berthings were completely flooded. Given the late hour, most crew members not standing watch would be in the berthing.
It is unclear how much warning the crew had that a collision was imminent, and there's been no immediate word on the fate of those aboard the ACX Crystal.
Two sources told Navy Times the crew had made progress on dewatering the ship, but the status of the flooded compartments remains unclear.
The Fitzgerald is currently under its own power but with limited propulsion, officials said. The guided missile destroyer Dewey, along with two Navy tugs and aircraft, are en route to assist as quickly as possible, according to a news release from U.S. 7th Fleet.
The Japanese Coast Guard cutters IZUNAMI and KANO, and a Japanese helicopter, are assisting.
"U.S. and Japanese support from the Navy, Maritime Self Defense Force and Coast Guard are in the area to ensure that the Sailors on USS Fitzgerald have the resources they need to stabilize their ship," said Adm. John Richardson, chief of Naval Operations, in the release. "As more information is learned, we will be sure to share to it with the Fitzgerald families and when appropriate the public. Thank you for your well wishes and messages of concern. All of our thoughts and prayers are with the Fitzgerald crew and their families."
"Right now we are focused on two things: the safety of the ship and the well-being of the Sailors," said Adm. Scott Swift, commander of the U.S. Pacific Fleet. "We thank our Japanese partners for their assistance."

Japanese media aired footage of the stricken Fitzgerald. The violent collision occurred on the ship's starboard side, under the the bridge. The ship's crew has set up water eductors, which means they're combating flooding.
Benson, the ship's skipper, previously commanded the mine sweeper Guardian. The extent of his injuries are unclear.
