↑PEARL HARBOR (Oct. 31, 2018) - The medium displacement unmanned surface vehicle (MDUSV) prototype Sea Hunter pulls into Joint Base Pearl Harbor-Hickam, Hawaii, Oct. 31, 2018. Sea Hunter's arrival in Hawaii demonstrates that MDUSVs are capable of deployed blue-water operations, enabling a new class of naval system. Highly autonomous USVs like Sea Hunter are creating a new paradigm for Navy surface forces, as they are capable of carrying a variety of payloads and performing many missions, including independent operations from manned Navy ships.
