The boat also shattered previous records of submarine speed and distance, and in 1958 completed Operation Sunshine, a secret voyage that made it the first sub to go to the North Pole. During the Cold War, the United States aimed to build a more advanced sub than had ever been seen before, and found success with the USS Nautilus. Until 1954, as The New York Times explains, “submarines were basically surface ships that could submerge at slow speed for a few hours.” When the Nautilus joined the fleet on September 30 that year, it had the unprecedented ability to produce its own power and fresh water-allowing it to stay underwater for weeks instead of hours. The world's first nuclear-powered submarine marked another important milestone in underwater technology.

Because the Hunley is so old and still being studied, however, visitors can’t enter inside. The sub eventually went on display in North Charleston, where those who visit can learn not only about the vessel itself and the stories of its crew but about the technology used to recover it. The vessel included technology they had not expected to find, such as a flywheel designed to act as a break for the propeller-an advanced feature for its time. Luckily, the sub was in remarkable shape, Hambrick explained, because it had been buried relatively quickly in a layer of silt that protected it from salt erosion. In August 2000, the team dredged up the Hunley and found a much more impressive machine than they’d imagined rotting beneath the sea. “Nobody has raised an entire ship before, so they had to go about figuring out how to do it,” Sherry Hambrick, who works for the nonprofit that now displays and preserves the Hunley, told. But to actually raise the sub from the ocean required a whole new kind of effort. Still, no dice. Finally, on May 3, 1995-20 years ago this month-a team of archeologists funded by adventure novelist Clive Cussler finally found it. Barnum even offered a reward of $100,000. The Hunley earned that inaugural honor during the Civil War, when it was built by the Confederate side and used in 1864 to attack the USS Housatonic with a 135-pound torpedo. The Hunley itself sank a little while later, under mysterious circumstances. For years afterward, explorers and treasure-seekers tried to locate the boat, and P.T. Hunleyin North Charleston, South Carolina. To see the first combat submarine ever to sink an enemy ship-a big milestone in the history of warfare- visit the H. Hunley, North Charleston, South CarolinaĪ drawing of the Hunley, showing its tightly packed crew members. And if you want to ride in one yourself, there are even some tourist submersibles that can take you underwater. A host of famous submarines are on display around the world, ready for visitors to explore. According to the company that sells it, the orca-styled submersible can be yours for $90,000.įor those who don’t want to join the Navy-or don’t have $90,000 lying around-there’s still hope for adventure. Today, submarines can be hulking-such as the 574-foot-long Soviet Typhoon-or sleek and miniature, like this two-person sub that looks and moves remarkably like a killer whale. Still, only one person could squeeze into Bushnell’s ship, which Parrish writes looked like two bathtubs clamped together, or like the shell of a strange oyster. Other inventors continued to make rudimentary submersibles until finally, in 1775, a man named David Bushnell created a machine that fits Parrish’s definition of a submarine: a vessel that can propel itself on water but also underneath it, and that can sink and rise again at will. This craft worked 15 feet below the surface of the Thames River, and according to Tom Parrish, author of The Submarine, even King James I visited onboard, despite the risk of drowning. He wouldn’t share them, he said, “because of the evil nature of men who practice assassination at the bottom of the sea.”ĭa Vinci never constructed his machine, as far as we know, and it wasn’t until about 1723 that a submersible came to life. Famed inventor Leonardo da Vinci, who died in 1519, had an idea for a submersible vessel but kept his sketches a secret. The idea of a ship that can travel underwater has been around far longer than the technology to make it possible.
