Submarines might seem like modern marvels, but the first designs date back to 1620, when Dutch inventor Cornelis Drebbel built a wooden, leather-covered vessel that could travel 20 feet underwater!
During the American Revolution, the Turtle, a one-person hand-powered sub, was used to try and attack British ships. By World War I and II, submarines became crucial for naval warfare and exploration.
Today’s submarines aren’t just for military use—they play key roles in scientific research, deep-sea exploration, and even searching for lost shipwrecks!
