US Army's 'Phaser' could fry entire drone swarms in a volley

While the US military has enjoyed several decades of aerial dominance with few enemy fighter planes to shoot down, the emergence of ISIS drones presents a new threat to American ground troops. To combat swarms of these cheap, small dangers, the US Army is testing a new anti-air device that is designed to blow multiple UAVs out of the sky in a single shot. They call it the Phaser. The Raytheon-built "Phaser" is a microwave-emitting dish that sits atop a shipping container containing its diesel generator power source. It relies on external radar systems to track targets, then fires a burst of radiation powerful enough to fry control systems, enough to knock drones out of the air.
