DARPA Robot Ship Hunts Down Silent Subs

If you are a submariner, then chances are you would subscribe to the idea that there are two different kinds of ships: subs and targets. The forward thinking folks over at the Pentagon intend to work on a new kind of surface ship which is capable of transforming a sub into a target. Needless to say, the submarine hunter will not have a human controlling it from within, as you can see in the video above.

This particular maritime robot is known as the Anti-Submarine Warfare Continuous Trail Unmanned Vehicle, or ACTUV for short, where its “radically different” design allows the ACTUV to keep surface ships from ending up as sitting ducks. The surface-gliding ACTUV will be designed to stay on course on a hunt for 60 to 90 days, and while it sounds scary, it has yet to be realized – making it stuck on the drawing board as at press time. Sonar pods located underneath the belly of the ACTUV will create an acoustic image of a submarine, where it will then pursue it at high speed. The moment the ACTUV figures out that it is locked on to a potential target, it will ping nearby Navy ships via through a satellite link.

SAIC shows how its antisubmarine drone ship tracks its silent targets

Some of us have been feeding advice to DARPA’s ACTUV sub-tracking drone project for more than a year, but we haven’t had a in-depth look at how the autonomous ship will go about its business, especially when chasing very silent diesel-electric subs. Thankfully, craft designer SAIC has stepped in with a detailed video tour. If there’s suspicions that a diesel sub is in the area, the US Navy can deploy sonar buoys that give the ACTUV an inkling of where to go first. After that, the drone takes over with both long-range and short-range sonar. The vehicle can gauge the intent of ships in its path (with human failsafes) and hound a target for up to 13 weeks — either letting the Navy close in for an attack or, ideally, spooking the sub into avoiding conflict in the first place. While ACTUV won’t hit the waves for years, there’s a promise that we’ll always know about underwater threats and deal with them on our own terms.

DARPA’s Next Sub Hunter Won’t Need Us Puny Humans [Monster Machines]

The US Navy has a bit of a sub problem. While the American fleet has contracted over the past two decades, numerous nations that aren’t exactly our BFFs have expanded, with new, ultra-quiet diesel-electric subs. This proliferation has grown into a national security threat, but DARPA may soon have a solution—robotic submarine trackers. More »
