In a brief update to those robot soldiers of the future, I noted that the US Army announced yesterday that it had reached a milestone of one million hours of unmanned flight. At present, to my limited knowledge, all the UAVs (Unmanned Aerial Vehicles) flown by the US have a human controller, but I’m willing to bet that autonomous robotic systems to make data analysis and response quicker (thus avoiding delays in analysis and decisions or through lost telemetry) are in the works. As the US DOD piece says, “the Army continues focusing on the future, improving capabilities and fielding new systems”. Vague, yes. Of interest to military ethicists, certainly.
