Debris scattered over a large area at the bottom of the sea in the Philippines indicate that the massive Japanese World War II battleship Musashi was blown into pieces in an undersea explosion 70 years ago. “The wreck is actually very damaged,” said David Mearns, a marine scientist on the Musashi research team. “It appears she suffered at least one, if not two, magazine explosions which would have sheered off the bow and the stern, and its entire middle section of its super-structure.” The debris scattered in areas approximately 2,600 feet by 1,640 feet, according to the research team.
