Abstract: An unmanned underwater vehicle may comprise a remotely operated underwater vehicle and an autonomously operating underwater vehicle. The unmanned underwater vehicle may also comprise a first connection to the remotely operated underwater vehicle. The first connection may serve to exchange data. The unmanned underwater vehicle may additionally comprise a second connection to the remotely operated underwater vehicle. The second connection may serve to supply energy. The unmanned underwater vehicle may still further include a third connection to the autonomously operating underwater vehicle, which third connection serves to exchange data.

Abstract: A submarine vehicle may include a storage area for storing loads. The submarine vehicle may further include a pressure hull. The submarine vehicle is configured to pick loads up from a seabed and/or set loads down on the seabed. The storage area may be positioned outside the pressure hull and, in some examples, between numerous pressure hulls. Further, the storage area may include a lower hatch disposed on an underside of the pressure hull or an upper hatch disposed on a top side of the pressure hull. Some submarine vehicles may include a load transporting system for picking the load up from the seabed, setting the load down on the seabed, and/or conveying the load within the storage area.
