Ukraine: Russian Fiber Optic Drones Penetrate Cities Far Behind Front Lines

Russian forces are increasingly deploying fiber-optic-controlled drones that can strike deep inside Ukrainian cities. This is raising concerns about civilian and military vulnerabilities far from the front lines.

Unlike conventional radio-controlled drones, these unmanned systems are linked to their operators via long spools of fiber-optic cable. This connection makes them largely immune to jamming and terrain obstacles. The technology allows precise, real-time control over long distances, although heavier spools can reduce speed and maneuverability.

A recent strike in Kramatorsk, a city of roughly 100,000 residents located about 12 miles from the frontline in Ukraine’s Donetsk region, demonstrated the potential of this technology. Video footage shows the drone navigating over urban streets before hitting a parked vehicle. While no casualties were reported, the incident highlights the growing reach of these systems into urban areas that were previously considered relatively safe.

Both Russia and Ukraine now operate fiber-optic FPV drones capable of ranges up to 25 miles, with research underway to extend that range to 30 miles or more. Analysts warn that the increasing reach of these drones is eroding the concept of rear areas for military logistics and civilian settlements.

Serhii Sternenko, a Ukrainian drone developer, noted that these drones can reach farther than many assume.

Ukraine has rapidly scaled its own fiber-optic drone production, with more than 35 companies now building these systems. Experts warn that, combined with AI-assisted controls and long-range telecom networks, fiber-optic drones could disrupt supply lines, threaten urban centers, and alter the strategic balance in eastern Ukraine.
