Submersible ship

A submersible ship, commonly called a submarine, is a specialized vessel designed to operate underwater. It is built with a strong, watertight hull that allows it to dive beneath the water's surface and stay submerged for extended periods. Submarines are used for various purposes, including defense, scientific research, and exploration. They can move silently using powerful engines and ballast tanks to control buoyancy. Unlike ships that stay on the surface, submarines are capable of navigating underwater, providing stealth and access to areas unreachable by surface vessels.
