Tokyo 17 Jun (ANA) - 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 USS Fitzgerald's commanding officer, who was taken to hospital by helicopter. The destroyer collided with the container ship about 56 nautical miles (104km) south-west of Yokosuka. Aerial images showed heavy damage to the Navy ship's starboard side after the collision at about 02:30 local time on Saturday (17:30 GMT Friday). The collision occurred near Yokosuka, a Japanese port city that is home to the US 7th Fleet, which comprises up to 80 submarines and ships and including the USS Fitzgerald. It is unclear where the 154-metre (505ft) guided missile destroyer ship was heading at the time. The ACX Crystal, a 222-metre (730ft) Filipino-flagged container ship, was travelling between the Japanese cities of Nagoya and Tokyo. Marine traffic records suggest the ACX Crystal made a sudden U-turn roughly 25 minutes before the collision with the USS Fitzgerald. It is not clear why it changed course. Marine traffic records suggest it was travelling at 14.6 knots (27km/h) at the time of the collision.(ANA)
