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).
Atlantic Marine was an American shipbuilding and construction company.
 It operated two shipyards, one in Mobile, Alabama and the original corporate location, a smaller one in Jacksonville, Florida where its headquarters was located.
