A new hunter is lurking in the deep -- and it's made of metal, silicon, and lots and lots of artificial intelligence. The Defense Advanced Research Projects Agency (DARPA) officially launched its unmanned submarine-hunting ship, holding a christening ceremony on Thursday for the "Sea Hunter." The new vessel is part of DARPA's larger initiative to use artificial intelligence (AI) for a wider array of military decisions and tasks. The seafaring drone's task is to find and neutralize enemies' ultraquiet diesel submarines, the agency said. While the Sea Hunter, which is part of DARPA's Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) program, is not helmed by a human captain, people are still in the loop (at least for now).

The Defense Department christened the Sea Hunter, a 132-foot robot ghost ship designed to seek out and track diesel-powered submarines across the ocean. The start of the test phase for the program on Thursday signals a new dawn for autonomous systems at sea, which, Pentagon officials say, will perform an ever-wider variety of jobs and could fundamentally change the way militaries operate on the water. The Sea Hunter is the first of a new type of ocean drone, called an Anti-submarine Warfare Continuous Trail Unmanned Vessel, or ACTUV. The goal of the program: field an autonomous ship with the range and endurance to go anywhere in the world while avoiding collisions with other ships and obeying the rules of navigation. "Current unmanned surface vessel systems and concepts are operated as close-adjuncts to conventional manned ships – they are launched and recovered from manned ships, tele-operated from manned ships, and are limited to direct support of manned ship missions. The ACTUVsystem will be a first of its kind unmanned naval vessel that is designed and sized for theater or global independent deployment," reads the program's description from 2014.

The autonomous vessel can travel on the high seas at speeds up to 27 knots for months on end without a single crew member. The 130-foot ACTUV can be remote-controlled, but its primary use is as an autonomous vessel that can operate safely near manned ships and accommodate all weather conditions. No crew means greater safety for potentially dangerous missions like countermining and submarine tracking. ACTUV is now slated for joint testing in open water between DARPA and the Office of Naval Research to determine viable payloads and potential uses for this sub-hunter robot.

"Although ACTUV will sail unmanned, its story is entirely about people," Scott Littlefield, DARPA program manager, said in a statement.
