The first 132 foot long ship, officially named 'The Anti-Submarine Warfare Continuous Trail Unmanned Vessel' will take to the water on April 7th.



Darpa director Dr. Arati Prabhakar and deputy director Dr. Steve Walker revealed the craft.
'Imagine an unmanned surface vessel following all the laws of the sea on its own,' Walker told media, 'and operating with manned surface and unmanned underwater vehicles.'
The robot boats will go to sea for us to three months at a time.
It will be christened in April in Portland, Oregon, and then begin to demonstrate its long-range capabilities over 18 months in cooperation with the Office of Naval Research and the Space and Naval Systems Warfare Command.



The project began in 2010, when 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.
In six weeks of tests along a 35-nautical mile stretch of water off of Mississippi earlier this year, testers at engineering company Leidos and Darpa put the ACTUV's systems through 100 different scenarios.
The test boat was able to tail a target boat at 1 kilometer's distance, something military bosses say is a major step forward.
'Picking up the quiet hum of a battery-powered, diesel-electric submarine in busy coastal waters is 'like trying to identify the sound of a single car engine in the din of a major city,' says Rear Admiral Frank Drennan, commander of the Naval Mine and Anti-Submarine Warfare Command.


Speaking at a National Defense Association Event in Virginia last year, Darpa program manager Ellison Urban outlined why the Navy needs sub-hunting boat bots.

'Instead of chasing down these submarines and trying to keep track of them with expensive nuclear powered-submarines, which is the way we do it now, we want to try and build this at significantly reduced cost.
'It will be able to transit by itself across thousands of kilometers of ocean and it can deploy for months at a time.
'It can go out, find a diesel-electric submarine and just ping on it,' said Urban.
Diesel-electric submarines have nearly-noiseless engines, are incredibly difficult to track from afar.
