Editorial: World’s Largest Anti-Submarine Robot Ship Ready for Sea-Trials in April

By Franz-Stefan Gady

The U.S. Navy’s largest unmanned surface vehicle designed to track Chinese and Russian subs will be christened in April.

The Pentagon’s Advanced Research Projects Agency (DARPA), an agency responsible for developing and testing cutting-edge military technologies, will test-launch the prototype of its 140-ton Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV), named Sea Hunter, in April this year, the deputy director of DARPA, Steve Walker, said, according to National Defense Magazine.

The 132-feet (40 meters) long Sea Hunter, an unmanned autonomous trimaran, will be christened in April 2016 at the Vigor Shipyards in Oregon and immediately afterwards commence sea-trials for 18 months to test its long-range tracking capabilities, among a host of other things. During the testing DARPA will closely cooperate with the Office of Naval Research and the Space and Naval Systems Warfare Command.

The ship’s primary mission will be tracking enemy subs in shallow waters, I noted in June 2015 (See: “US Navy to Deploy Robot Ships to Track Chinese and Russian Subs”). Furthermore, I explained that the ACTUV “is designed to operate autonomously for 60 to 90 days straight, surveil large stretches of ocean territory and — should an enemy sub be spotted — guide other U.S. naval assets to the vessel’s location to destroy it (the ACTUV itself is unarmed).”

“Imagine an unmanned surface vessel following all the laws of the sea on its own and operating with manned surface and unmanned underwater vehicles,” Walker told reporters during a briefing at DARPA headquarters in Arlington, Virginia on February 10. “We think the real cost savings will be in operating this vessel at sea compared to how we operate vessels today.”
