How do you keep track of increasingly stealthy Russian, Chinese and Iranian submarines? If you’re the U.S. military, you build a robotic ghost ship to follow them around the high seas.
In 2010, the Defense Advanced Research Projects Agency, or DARPA, announced that they were building a 132-foot autonomous boat to track quiet, diesel-powered submarines. The program was dubbed Anti-submarine Warfare Continuous Trail Unmanned Vessel, or ACTUV.

While it’s an interesting project, and an innovative approach, this isn’t how you counter diesel electric subs.
You mine their home ports before they deploy.
