Submission + - How the U.S. Army Plans to Defeat the Unthinkable: Drone Swarms (nationalinterest.org)
The U.S. Army seems to have some ideas: "The Army wants a weapon that can both detect and destroy a swarm of UAVs. It would "disrupt these platforms’ autonomous flight-control and navigation capabilities or cueing a weapons system like the Remotely-Operated Weapon Station (RWS) or other medium or large-caliber weapon.," said the Army's research proposal. The system would be mounted on vehicles or at Army installations. More interesting, the Army proposal also notes that it might be mounted on UAVs, which raises the possibility of using drones to shoot down other drones."
