Scientists Think They've Solved the Century-Old Mystery of Why a Navy Warship Suddenly Sank Off New York

(WASHINGTON) — A hundred years ago, a mysterious explosion hit the only major U.S. warship to sink during World War I. Now the Navy believes it has the answer to what doomed the USS San Diego: An underwater mine set by a German submarine cruising in waters just miles from New York City.

That's the conclusion of an investigation by scientists, archaeologists and historians convened by the U.S. Naval History and Heritage Command.
