In July, the Pentagon announced it was putting 20 million towards counter-drone weapons, citing the threat from ISIS. Shortly afterwards, pictures surfaced of an American-made anti-drone rifle in Iraq. Rather than destroying a drone with bullets, the Battelle Drone Defender stops drones by jamming GPS and radio signals, causing it to lose contact with its pilot and, ideally, land. Going further, DARPA wants the United States to have anti-drone lasers by 2020, a goal every part of the military, from the Air Force to the Marine Corps, is independently working towards. Laser weapons are costly to build, but their appeals as an anti-drone weapon is that every shot of directed energy is cheap, so one laser system could shoot down many cheap drones, without spending expensive missiles or lots of bullets to do so. In the meantime, people and police departments are exploring everything from elaborate net-guns to eagles as a way to take down drones.
