FAQs

What is the history of submarines?
Submarines have a rich history dating back to the 17th century, with various inventors and engineers contributing to their evolution. The first documented military use of a submarine was during the American Revolutionary War, showcasing the early potential of underwater vessels.

How do submarines submerge and resurface?
Submarines use ballast tanks to control their buoyancy. By adjusting the amount of water in these tanks, the submarine can either submerge or surface. When the tanks are filled with water, the submarine becomes heavier than the water it displaces, causing it to descend. Conversely, expelling water from the tanks allows the vessel to rise to the surface.
