WWII had come to a close, and the U.S. was the first to seize a new class of giant Japanese submarines. The next step was to analyze them quickly and then sink them, before the Russians could learn their secrets.
It began with a barrel-shaped submersible that patrolled New York Harbor during the American Revolutionary War. Since then, the submarine has evolved into a vital weapon of war. Dive in as we track its history, from the 1775 Turtle to the 1879 Resurgam to the mighty German U-boats and nuclear subs of today. Rare archival footage, visits to surviving decommissioned subs, and interviews with crewmembers help explain how these machines became such a powerful symbol of naval supremacy.
