Laser Dune Buggy Battles Armed UAVs

Raytheon has developed a vehicular directed-energy weapons system capable of disabling UAVs from long distances.

Unmanned aerial vehicles (UAVs) have become commonplace as battlefield “birds of prey,” equipped for offensive maneuvers. Because they represent relatively low-cost weapons, suitable defensive measures should also be cost-effective, and the high-energy lasers (HELs) have proven to be quite capable in defending against armed UAVs. Raytheon Co. is working on bringing these defensive laser-based systems where needed, having developed low-cost dune buggies equipped with HELs that can combat rugged desert terrain (see photo).

“Basically, we’re putting a laser on a dune buggy to knock drones out of the sky,” explains Dr. Ben Allison, director of the company’s high energy laser product line, who works on Raytheon’s campus in McKinney, Tex. The job requires a bit more than simply bolting down a laser system into a ground vehicle, since the HEL must be combined with a variation of Raytheon’s Multi-spectral Targeting System infrared (IR) and electro-optical sensors, and with everything installed on a Polaris MRZR all-terrain vehicle—the aforementioned dune buggy.

Allison’s efforts were motivated by a report from Raytheon Chairman and CEO Tom Kennedy about an allied nation’s use of a Patriot missile to shoot down a low-cost drone equipped with grenade type munitions, as well as the need for a cheaper means to shoot down armed drones. Allison sought to use Raytheon’s existing resources to develop a more cost-effective counter-UAV defense system than a Patriot missile, and without having to perform an extended amount of research to achieve the solution. By combining the HELs with the multiple sensors on an all-terrain vehicle, the defensive system provides the necessary power and the mobility needed to defense against UAVs. It can run on stored charge from 220 VAC or be equipped to run on a generator on board the all-terrain vehicle.
