Ukraine rolls out drone-stopping razor fence to thwart attacks
5 hours ago
- Ukraine has developed a new barrier system called Chaharnyk that defends against fiber-guided attack drones by cutting their communication cables.
- Fiber-optic drones use cables instead of radio to avoid jamming; Russia has increased their use, with 60% of FPV attack drones now fiber-guided.
- Existing passive defenses include net tunnels over key roads, but Chaharnyk offers an active alternative using a motorized wire fence with hooks.
- The system is battery-powered, weatherproof, remote-controlled, and can be set up by two people in under an hour.
- An acoustic sensor detects drones and triggers the barrier, which cuts the fiber cable with a claimed 95% success rate, though battlefield reliability is questioned.
