IDF Deploys Rotating Wire Fences to Counter Hezbollah’s Fiber-Optic Drones
To counter Hezbollah’s jam-resistant fiber-optic FPV drones, the IDF has adapted a low-tech Ukrainian innovation: motorized rotating barbed-wire fences.
The Israel Defense Forces (IDF) have adapted a low-tech Ukrainian battlefield innovation, deploying motorized rotating wire fences to disrupt Hezbollah’s hard-to-jam fiber-optic guided drones in southern Lebanon operations.
Hezbollah has increasingly used small first-person view (FPV) drones controlled via thin fiber-optic cables, which lay along the ground as the drone advances. These systems are immune to traditional radio jamming and difficult for radar to detect, posing a persistent threat to IDF troops and vehicles.
The new Israeli countermeasure features barbed or razor wire attached to iron poles, powered by small electric motors that keep the wire spinning continuously. When a drone’s trailing fiber-optic cable snags on the rotating barbs, it wraps around the wire, twists, and severs, breaking the control link and causing the drone to crash. tomshardware.com
The IDF’s Ground Technology Brigade developed the localized version, designed for rapid, independent deployment by individual battalions. The system emphasizes simplicity and quick installation in forward positions.
A senior IDF officer described a multi-layered defense strategy as the most effective approach against these threats. It combines:
Tens of thousands of 5.56mm frangible rounds, designed to fragment on impact for safer use near friendly forces while effective against small aerial targets,arrived in Israel recently and are being distributed to troops operating inside Lebanon.
The adaptation mirrors broader lessons from the Ukraine-Russia war, where similar rotating barbed-wire barriers have proven effective against fiber-optic FPV drones. Israeli forces have also expanded use of physical netting on vehicles as an additional passive defense.
Military officials acknowledge that no single solution is foolproof against the evolving low-tech threat, but the combination of kinetic, physical, and electronic measures aims to reduce the drones’ effectiveness while minimizing reliance on high-cost interceptors.
