Israeli Military Lacks Defenses Against Hezbollah Fiber-Optic Drones

Several soldiers were wounded over the past week by Hezbollah attack drones in Lebanon. The incidents highlight ongoing difficulties for the Israeli military in countering fiber-optic-guided drones, which cannot be intercepted by electronic warfare systems.

The defense establishment identified solutions for these drones two years ago. A surge in Hezbollah drone attacks has drawn attention to gaps in military preparedness. The drones use fiber-optic guidance that prevents jamming, unlike radio-controlled systems that electronic measures can disrupt.

The defense establishment saw available technology to address the threat. Despite warnings from experts over the past two years, the countermeasures have not reached operational units.

Background on the Threat Fiber-optic-guided drones transmit commands through thin cables that unspool during flight. This method makes them immune to radio-frequency jamming that has proven effective against other unmanned aircraft in the conflict. The Israeli military has relied on electronic warfare to counter many Hezbollah drones since fighting intensified.

The emergence of fiber-optic variants has reduced the effectiveness of those existing defenses.

Systems developed by an Israeli company have been viewed as a potential solution by the defense establishment. These tools have not been distributed to forces operating along the Lebanon border. The wounding of soldiers in recent days has renewed focus on the gap between identified solutions and field deployment. The Israeli military continues to operate in the area while addressing the threat.
