Automated combat systems have long held a place in science fiction. Warfare turns into battles between machines, some directly controlled by human beings and some completely autonomous. We’ve all heard about the airplane drones that are seeing significant use in recent conflicts, but here’s something quite different. The US Navy is testing autonomous swarm boats. They’re small, unmanned boats that sense the environment and work together to achieve their objective. That may be to protect a particular ship, attack a target, etc. It’s quite interesting. Note, however, that the Navy doesn’t allow the swarm boats to utilize their weapons unless there is a human being on board. The linked video explains in more detail.
