Amazing Discovery of WWII Japanese Sub

The dramatic discovery of a lost World War II-era Imperial Japanese Navy mega-submarine by a University of Hawaiʻi and U.S. National Oceanic and Atmospheric Administration team in December 2013 inspired a new search by NHK, the Japanese Broadcasting Corporation, to find key missing pieces of the battleship. The recent survey, the first to return to I-400 submarine since its discovery, successfully located, mapped and captured on video for the first time not only the submarine’s hangar and conning tower (navigation platform), but an unexpected and significant new discovery – the submarine’s bell.
