How a laser defeats hostile drones
A small quadcopter, just like the ones they sell for a few hundred dollars at big-box stores, flies against a cloudless blue sky. On the ground, atop a dune buggy, a glass-paned turret pivots in the drone’s direction.
Inside the vehicle, there’s a motorized whirr. Moments later, flames start to flicker near a microscopic hole in the center of the drone’s wings, and the hard plastic begins to melt. A few seconds later, it crashes to the ground.
This is what it looks like when Raytheon Intelligence & Space, a Raytheon Technologies business, demonstrates the use of lasers to defeat hostile drones. Counter-UAS lasers such as RI&S’ High-Energy Laser Weapons System give military service members and public-safety officials a relatively inexpensive way to defeat swarms of cheap, weaponized drones.
The Raytheon Intelligence & Space High-Energy Laser Weapons System offers a cost-effective counter-UAS solution rather than firing a multi-million dollar missile to disable a $500 commercial quadcopter. Furthermore, commercial, small drones have become much more sophisticated, fly faster and can navigate autonomously without using radio frequencies, making them jam-resistant.
