Submarine

A submersible vessel, typically a warship, designed to operate underwater. Submarines are used for a variety of purposes, including military operations (such as surveillance, offensive strikes, and protecting naval assets), scientific research, and occasionally for civilian uses like tourism and underwater exploration. They can be powered by diesel-electric systems, nuclear reactors, or other advanced propulsion systems. The design of a submarine emphasizes stealth, hydrodynamic efficiency, and the ability to withstand immense pressure at depth.
