What underwater boat is fully autonomous and made by BAE Systems?
Submarine A submarine (or simply sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed vessel. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. The noun "submarine" evolved as a shortened form of "submarine boat"; by naval tradition, submarines are usually referred to as "boats" rather than as "ships", regardless of their size ("boat" is usually reserved for seagoing vessels of relatively small size).
DSV Shinkai The Shinkai (しんかい) is a manned research submersible that can dive up to a depth of 600 m. It was completed in 1970 and until 1981 it had the greatest depth range of any manned research vehicle in the Japan. The "Shinkai" is owned and run by the Japan Coast Guard and it is launched from the support vessel "Otomemaru"(乙女丸).
