Now we have an unmanned surface warship.

The boat you see here is the newly christened Sea Hunter — formally known as the Anti-Submarine Warfare Continuous Trail Unmanned Vessel, or ACTUV. Developed by the Pentagon's Defense Advanced Research Projects Agency (Darpa) and built by US defence contractor Leidos, the 132-foot-long, diesel-powered vessel is an experimental autonomous submarine-hunter and mine-detector, capable of cruising the open seas for weeks or months at a time, without human guidance of any sort, onboard or remote.
