According to BBC report, seven US Navy crew members are missing after their ship collided with a merchant vessel off the coast of Japan.
Among the injured is the ship's commanding officer who has been taken to hospital by helicopter.
Report also says, Navy destroyer USS Fitzgerald collided with the container ship ACX Crystal about 56 nautical miles (103km) south-west of Yokosuka early hours on Saturday.
Aerial images showed heavy damage on the destroyer's starboard side.
The ship's commanding officer, Cmdr Bryce Benson, was in a stable condition after being transferred to US Naval Hospital Yokosuka, according to Navy officials.
Two other sailors were flown to hospital by helicopter for treatments for "lacerations and bruises".
It said earlier that the USS Fitzgerald had experienced flooding in some areas, and the full extent of injuries was being determined.
It also said the 154m ship was now on its way to Yokosuka - under its own power, but with limited propulsion, BBC report said.
