Sunken WW2 Era Mega Submarine Found Off Coast of Hawaii

Was intentionally scuttled by the US Navy and lost at sea during the war

A Japanese submarine that was lost at sea after it was intentionally scuttled by the U.S. Navy during World War II has been located by a team of explorers off the coast of Hawaii.

A spokesman for the University of Hawaii at M?noa said in a press release the discovery of the Imperial Japanese Navy's mega-submarine, the I-400, solves the decades-old mystery of where the submarine lay on the ocean floor.
