Built by Raytheon Missile Systems of Tuscon, Arizona, the 32-kilowatt infrared laser is shown illuminating and heating the wingtip and then the underside of what looks like a radar-seeking drone – until its remote pilot loses control and the aircraft catches fire and plummets into the ocean.

“Three similar drones were also successfully engaged at militarily significant distances by the solid-state laser” in May and June, says Mike Booen, the firm’s vice president. “It’s a world first over open sea.”
