An American submarine that was missing in the Second World War was rediscovered at the bottom of the East China Sea.

In 1944, the aircraft carrier "Grayback" and its 80 crew members were missing when they were attacked by Japanese aircraft.

After searching for military documents with the correct coordinates, an underwater exploration project found the submarine near the Okinawa coast in Japan.

The original coordinates were incorrectly translated and the numbers were missing.

The families of the 80 crew members who were on board the submarine have been told about its discovery. 

For Kathy Taylor, whose uncle John Patrick King was a soldier on the vessel, the discovery brings closure. She said, "I have promised to find him when I was a child, or to follow him or keep his memory."
