The U.S. Navy and the Defense Advanced Research Projects Agency (DARPA) are now testing a new unmanned drone warship.
The first Navy drone ship is a 132-foot ACTUV (Antisubmarine warfare Continuous Trail Unmanned Vessel) known as Sea Hunter, which cost around $120 million to build. The military says more can now be produced for $20 million or so each. But some are concerned that with no humans at the controls, these “robot ships” could be hacked, pwned remotely, and used by America's enemies to attack the United States.
