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).
French submarine Téméraire (S617) Le Téméraire is a "Triomphant"-class ballistic missile submarine of the French Navy, launched in January 1998, and commissioned in December 1999, six months behind schedule.
