Ukrainian KB Logic presents Chabarnik counter-FPV system

Bottom line

Ukrainian KB Logic has presented the 'Chabarnik' counter-FPV system, which uses acoustic sensors to detect drones and activates spinning barbed wire to sever fiber-optic control cables.

Why it matters

As Russian forces increasingly rely on fiber-optic FPVs to counter EW, kinetic countermeasures like Chabarnik offer a complementary layer of defense that does not rely on spectrum dominance, potentially disrupting Russian drone coordination tactics.

Ukrainian defense firm KB Logic has unveiled the ‘Chabarnik’ system designed to counter fiber-optic FPV drones. The system employs acoustic sensors to detect incoming drones from over 15 meters away. Upon detection, it activates motors to spin a barbed wire barrier, physically severing the control cable of the incoming drone. This represents a novel kinetic countermeasure specifically targeting the guidance mechanism of fiber-optic UAVs, which are increasingly used by Russian forces to bypass electronic warfare jamming.
