Unmanned patrol boats???

The Navy plans to add self-guided unmanned patrol boats to its fleet. The service presented the new technology on the James River in Virginia. Defense officials said the boats can leave warships they're protecting and swarm to attack potential threats. The Navy hopes one day the boats could help stop attacks like the bombing of the USS Cole. Arlington-based Office of Naval Research demonstrated the new technology and called it a success. Officials said the boats could join the Navy's fleet within a year.
