Experience a kaleidoscope of real-life underwater missions, ranging from ancient ruins covered by reservoirs in the desert Southwest to a World War II submarine off the Alaskan coast; from the Isle Royale shipwrecks in the frigid Lake Superior to the USS Arizona in Pearl Harbor; from the HL Hunley, the first submarine in history to sink an enemy ship, in Charleston Harbor to the ships sunk by atomic bombs at Bikini Atoll, and much more.
