An American ocean exploration team has filmed the world's deepest known shipwreck the first time. The ship is a World War II US Navy battleship called the USS Johnston. It was sunk the Japanese Navy on October 25th, 1944 during the Battle of Samar the Philippine Sea. The wreck now sits the ocean floor at a depth around 6,456 metres. The film crew managed to go down to that incredible depth and darkness and map and film the whole shipwreck. They filmed the ship a specially built submersible that can deal the pressure of the deep ocean. They discovered it was 30 metres deeper than previously thought. The filming took place two eight-hour dives.
The explorers are a company called Caladan Oceanic. Its founder is Victor Vescovo, a former US Navy commander. He has a passion adventure and visiting some the world's hardest-to-get-to places. He holds the record being the first person ever to get to the top all the world's continents, both poles, and the bottom all the world's oceans. Mr Vescovo said the mission to film the USS Johnston was a personal one because that ship and his submersible were made the same shipyard and both served in the US Navy. He said: "As a US Navy officer, I'm proud to have helped bring clarity and closure to the Johnston, its crew, and the families those who died it."
