SUBMARINES, SUBMERSIBLES, ROVs

submarine:            A crewed (don't use manned) vehicle that is not routinely lifted out of the water.

submersible:        A crewed vehicle that is tended by a mother ship and is lifted out of the water after a dive.

ROV:                            An uncrewed (don't use unmanned) remotely operated vehicle.

Write the name of an ROV or submersible in italics. If the submersible's only name is its hull number, italicize that as you would a ship name.  ROV stands for "remotely operated vehicle."
