 UAV advocates claim the Air Force abandoned UAVs for strike missions because of inclination of "hotshot flyboys" to keep the mission for themselves, but in fact the concept has always suffered from "command and control" problems, such as the vulnerability of communications links to jamming and spoofing, and the need to hit specific targets and not accidentally kill civilians or friendly troops.As attention focused on the combat capabilities of attack drones, the USN and USAF were looking for drones that could turn 6Gs and quickly roll into tight turns.While at the same time, US designers were wondering if "dog-fights" between robot planes were just around the corner.
