These preserved submarines open their hatches to visitors who want to see where sailors lived and fought beneath the ocean surface. From World War II patrol boats that hunted across the Pacific to the first nuclear-powered vessel that changed naval history forever, each submarine reveals the cramped reality of underwater service. You walk through narrow steel corridors, peer into bunks stacked three high, and stand where officers once studied charts and gave orders in near silence. The collection includes vessels from harbors across the United States and around the world, each one a working museum where the instruments, torpedo tubes, and engine rooms remain as they were during active duty. Some of these submarines sank enemy warships and rescued Allied prisoners during the Second World War. Others served through the Cold War, carrying crews on patrols that lasted weeks without seeing daylight. A few pushed the limits of technology, proving that nuclear reactors could power a vessel across thousands of miles and even under the polar ice. Whether docked in a busy port or resting beside a quiet lake, these submarines bring you face to face with the men who descended into the deep, closed the hatch, and did their work in spaces smaller than a city bus.
