The full name is “The Anti-Submarine Warfare Continuous Trail Unmanned Vessel”, which collapses to the “ASW Continuous Trail Unmanned Vessel,” or ACTUV, pronounced “Active.” DARPA, c’mon. That’s quite a length to go to for a name that doesn’t even capture the coolest thing about this autonomous robot ship. ACTUV is built with submarine fighting in mind. “Optimized to robustly track quiet diesel electric submarines,” in DARPA’s words. There are lots of ways to hunt submarines, and no particular reason a sub hunter is better without any people on it. But why not make it unmanned? DARPA estimates using an unmanned vessel instead of a similarly-sized manned one will be save an order of magnitude on the cost of daily operation. In addition to anti-submarine work, Walker mentioned it could have a role in supplying other ships, logistics, and countering undersea mines. This last category is currently the most common application for unmanned boats, though often they’re much smaller vessels deployed from a larger ship. ACTUV will instead be, at 132 feet long and weighing 140 tons, will be larger than most unmanned ships (though still smaller than all but the tiniest U.S. Navy vessels). And it’ll be autonomous. “Imagine an unmanned surface vessel following all the laws of the sea on its own,” Walker told the assembled media, “and operating with manned surface and unmanned underwater vehicles.” That means they’re programming the laws of the sea into the very machine itself.
