Sea Hunter

The US Navy has a new unmanned sub hunter with enough fuel to make a slow journey around the world without once stopping for a refill.

The 132-foot vessel is powered by diesel engines and has a narrow hull stabilized by two outriggers and can survive in up to 30-foot seas. The sub hunter was designed to operate without any humans on board.   The ship can be operated remotely, similar to other drones in the Pentagon’s fleet of unmanned aircraft, ships and submarines. They also could eventually be operated in fleets and Defense officials say it is able to avoid crashing into other ships through advanced software and hardware that form automated “lookouts.”
