World War Two era Japanese submarine found off Hawaii coast.
Dec 3 (Reuters) - Scientists plumbing the Pacific Ocean off the Hawaii coast have discovered a World War Two era Japanese submarine, a technological marvel that had been preparing to attack the Panama Canal before being scuttled by U.S. forces.
The 400-foot (122-meter) "Sen-Toku" class vessel - among the largest pre-nuclear submarines ever built - was found in August off the southwest coast of Oahu and had been missing since 1946, scientists at the University of Hawaii at Manoa said.
The I-400 and its sister ship, the I-401, which was found off Oahu in 2005, were able to travel one and a half times around the world without refueling and could hold up to three folding-wing bombers that could be launched minutes after resurfacing, the scientists said.
The accidental discovery of the 1-400, an aircraft-toting I-400 mega sub, on the rock- and debris-littered ocean floor, some 2,300 feet (701 meters) beneath the surface, has solved the mystery surrounding a ship long thought to be further afield.
