An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs. Homing torpedoes can also be considered as a subclass of AUVs.

👉 Autonomous underwater vehicle in the context of Underwater vehicle
An underwater vehicle is any member of the class of watercraft that is intended to operate in the underwater environment, as opposed to surface vessels that only stay afloat on top of water. This article lists the types of underwater vehicle, with a brief description of each type. An underwater vehicle can be crewed or unmanned (which may be remotely operated or fully autonomous), and will generally, but not necessarily, have some form of onboard propulsion system.

Autonomous underwater vehicle in the context of Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as boats rather than ships regardless of their size.
Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; blockade running; nuclear deterrence; stealth operations in denied areas when gathering intelligence and doing reconnaissance; denying or influencing enemy movements; conventional land attacks (for example, launching a cruise missile); and covert insertion of frogmen or special forces. Their civilian uses include: marine science; salvage; exploration; and facility inspection and maintenance. Submarines can be modified for specialized functions such as search-and-rescue missions and undersea cable repair. They are also used in the tourism industry and in undersea archaeology. Modern deep-diving submarines derive from the bathyscaphe, which evolved from the diving bell.
Autonomous underwater vehicle in the context of Unmanned underwater vehicle
Unmanned underwater vehicles (UUV), also known as underwater drones, or unmanned submarines, are submersible vehicles that can operate underwater without a human occupant, either remotely operated underwater vehicles (ROUVs) or autonomous underwater vehicles (AUVs).
Autonomous underwater vehicle in the context of Littoral combat ship
A littoral combat ship (LCS) is a relatively small surface vessel designed for littoral warfare in near-shore operations. There are two LCS ship classes deployed by the United States Navy. The LCS was "envisioned to be a networked, agile, stealthy surface combatant capable of defeating anti-access and asymmetric threats in the littorals", although their ability to perform these missions in practice has been called into question.
Littoral combat ships are comparable to corvettes found in other navies. The Freedom class and the Independence class are the two LCS variants. Each is slightly smaller than the U.S. Navy's earlier Oliver Hazard Perry-class frigate but larger than Cyclone-class patrol ships. Each has the capabilities of a small assault transport, including a flight deck and hangar for housing two SH-60 or MH-60 Seahawk helicopters, a stern ramp for operating small boats, and the cargo volume and payload to deliver a small assault force with fighting vehicles to a roll-on/roll-off port facility. Standard armaments include Mk 110 57 mm guns and RIM-116 Rolling Airframe Missiles. They are also equipped with autonomous air, surface, and underwater vehicles. Possessing lower air defense and surface warfare capabilities than destroyers, the LCS emphasizes speed, flexible mission modules, and a shallow draft.
