The National Post reports that “the Pentagon took the Sea Hunter, a new vessel that promises to be the future of robotic warfare, out for a spin on Monday, showing off the self-driving ship off the cost of San Diego.”  

“The 40-metre-long boat is the world’s largest unmanned surface vessel and was developed to hunt submarines and underwater mines.”  

“The U.S. military’s research wing, the Defence Advanced Research Projects Agency, designed, developed and built the ship in a program that cost more than $150 million. The so-called drone ship will one day be able to travel thousands of kilometers across the sea for months at a time — all without a single crew member on board.”
