A submarine is a specialized watercraft that can operate underwater, employed by most Earth navies.

Prior and during the World War II, Germany was one of the world's leading nations in the area of submarine technology. Their submarines were named "U-Boats", the term deriving from the German Navy's system of naming its submarines with U- followed by a number, where the "U" stood for Unterseeboot (literally, "undersea boat"), the German word for submarine.
