Submarines are also used for marine and freshwater science and for work at depths too great for human divers. Nuclear powered submarines and other large submarines are classed as ships, but are customarily referred to by their crews as "boats". The term U-Boat is sometimes used in English, this comes from the German word for submarine, 'U-Boot', itself an abbreviation for Unterseeboot.
