Drones are great, but not when someone is doing something bad with one, like encroaching on protected airspace or spying on a forward-operating base. We’ve got an answer. Note: This device has not been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased in the United States, other than to the United States government and its agencies, until authorization is obtained. Under current law, the DroneDefender may be used in the United States only by authorized employees of the Federal government and its agencies, and use by others may be illegal. Due to Federal regulations, this video is a simulation of the Battelle DroneDefender™ system. It has, though, been successfully tested in Federal government-conducted field trials.
