According to MANA, the U.S. Navy said in a statement the USS Fitzgerald, an Aegis guided missile destroyer, collided with a merchant vessel some 56 nautical miles southwest of Yokosuka, a rare incident on a busy waterway.
Three aboard the destroyer had been medically evacuated, including the ship's commanding officer, Cmdr. Bryce Benson, who was reportedly in stable condition after being airlifted to the U.S. Naval Hospital on the Yokosuka base, the Navy said.
The other two injured were transferred to the hospital to treat lacerations and bruises, it said.
It was unclear how the collision happened. "Once an investigation is complete then any legal issues can be addressed," the 7th Fleet spokesman said.
"The USS Fitzgerald suffered damage on her starboard side above and below the waterline," the Navy said in a statement.
