AI overview
A submarine is a military vessel designed to operate underwater, capable of traveling beneath the ocean's surface while remaining hidden from detection. Submarines matter because they serve as strategic weapons platforms for nations, particularly for launching nuclear missiles, and represent a significant component of modern naval power and deterrence.

A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as boats rather than ships regardless of their size.
