Think you can take out a swarm of attack drones? DARPA wants to hear from you

DARPA is exploring how to defend against a swarm of attack drones. DARPA is already developing concepts for a swarm of drones to drop out of aircraft and has drones that can fly at 45mph. Now, in its never-ending quest to close capability gaps, the Pentagon's advanced research agency wants to develop a defensive system that can take out an attacking fleet of small unmanned air systems (sUAS). DARPA outlines in a new request for information its concerns about the impact of commercial drone technology on defense capabilities, particularly the protection of large and dispersed ground and naval forces where conventional weapons, such as missiles, might not be as effective in future. Responding to this threat, the agency wants a new technology that can rapidly "detect, identify, track, and neutralize" a potential attack from these drones.
