The Defense Advanced Research Projects Agency (DARPA) — otherwise known as the research arm of the U.S. military — has developed counter drone technology that disables suspicious drones attempting to disrupt mobile convoys by launching a pink, string-like substance.

The counter drone system, dubbed the Mobile Force Protection system, features a modified military Humvee vehicle that employs X-band radar to detect and track suspicious small unmanned aerial systems (sUAS).

Once a suspicious drone is detected, the Mobile Force Protection system launches its own drone that disables the suspicious sUAS with the pink string-like substance.

According to DARPA, the pink substance entangles the sUAS’s rotors, thereby disrupting its propulsion and forcing the suspicious drone to crash.

Although the Mobile Force Protection system was designed to protect convoys in transit, the system poses almost no threat to nearby civilians or property.
