World’s largest SELF-DRIVING WARSHIP completes its first sea trials

-

Dubbed the ‘Sea Hunter’, the 132ft ship is designed to travel thousands of miles out at sea without a single crew member on board.

The self driving warship has now completed its first trials - and passed with flying colours.

Experts say the vessel has the potential to revolution­ise not only the military’s maritime service but also commercial shipping.

The at-sea tests took place off the coast of San Diego, California.

‘The 132-foot trimaran, christened Sea Hunter at a ceremony in April, met or surpassed all performanc­e objectives for speed, maneuverab­ility, stability, seakeeping, accelerati­on/decelerati­on, and fuel consumptio­n, as well as establishi­ng confidence in mechanical systems reliabilit­y in an open-ocean environmen­t,’ said Leidos, who made the ship.

Sea Hunter is designed to operate for extended periods at sea with no person on board and only sparse supervisor­y control throughout deployment.

While initial vessel tests require a pilot on board the ship, later tests are planned to have no personnel on board.

The completion of Sea Hunter’s performanc­e trials is the first milestone in the two-year test program co-sponsored by DARPA and the Office of Naval Research.

Testing in upcoming months is scheduled to include testing of sensors, the vessel’s autonomy suite, compliance with maritime collision regulation­s, and proof-of-concept demonstrat­ions for a variety of U.S. Navy missions.

It marks the first step toward sending unmanned cargo vessels between countries, according to military officials, who showed off the ship in San Diego today before it was put in the water.

The Pentagon’s research arm, the Defense Advanced Research Projects Agency (Darpa) developed the ship along with Virginia-based Leidos.

Darpa will test it in conjunctio­n with the Navy over the next two years off California’s coast.

The tests will largely focus on its ability to react on its own to avoid collisions with seafaring traffic.

During the testing phase, the ship will have human operators as a safety net, but once it proves to be reliable, the autonomous surface vessel will maneuver itself — able to go out at sea for months at a time.

Program manager Scott Littlefiel­d said there will be no ‘remote-controlled driving of the vessel’.

Instead it will be given its mission-level commands telling it where to go and what to accomplish and then software will enable it to drive itself safely.

The military initially built the diesel-powered ship to detect stealthy electric submarines.

But developers say they believe it has the capability to go beyond that, including doing mine sweeps. There are no plans at this point to arm it. ‘There are a lot of advantages that we’re still trying to learn about,’ Littlefiel­d said.

Among them is the possibilit­y that the fullsize prototype could pave the way to developing crewless cargo vessels for the commercial shipping industry someday, he added.

Countries from Europe to Asia have been looking into developing fleets of unmanned ships to cut down on operating costs but the idea has sparked debate over whether it’s possible to make robotic boats safe enough to run on their own far from land.

The Internatio­nal Transport Workers’ Federation, the union representi­ng more than half of the world’s more than one million seafarers, has said it does not believe technology will ever be able to replace the ability of humans to foresee and react to the various dangers at sea.

The ‘Sea Hunter’ was built off the Oregon coast, and moved on a barge to San Diego’s coastline to begin testing.

The prototype can travel at a speed of up to 27 knots per hour, and is equipped with a variety of sensors and an advanced optical system to detect other ships, Littlefiel­d said.

The program to develop the ship cost $120 million, though Littlefiel­d said the vessels can now be produced for about $20 million.

During the collision tests, the ship will be programed to follow internatio­nal traffic rules for boats of its size.

There are no standards for unmanned ships yet, but Littlefiel­d believes that could change if vessels like this one make it out of the experiment­al stage.

The Navy over the years has experiment­ed with a number of unmanned systems — from drone helicopter­s to small, remotely controlled boats launched from ships. .
