Ukraine Tests Long-Range FPV Drones with Fiber Optic Control

Ukraine has conducted tests of long-range first-person-view (FPV) drones equipped with fiber optic control, the state defense technology cluster Brave1 reported.

The trials were organized with support from Brigadier General Andriy Lebedenko, Deputy Commander-in-Chief of the Armed Forces of Ukraine, and the Innovation Directorate of the Armed Forces of Ukraine.

Over 15 drone manufacturers participated in the testing at a specialized training ground, where FPV drones completed a 20 km obstacle course and simulated target attacks. The results showed that Ukrainian developers have extended the range of these drones beyond 20 km, surpassing the previous 5-10 km limit. This advancement allows drones to perform long-range missions while remaining undetectable to radio reconnaissance.

Unlike traditional radio-controlled FPV drones, fiber optic-controlled models are resistant to electronic warfare interference. They transmit high-quality images and remain unaffected by radio noise. In addition to aerial drones, seven manufacturers of fiber-optic-controlled ground robotic systems also demonstrated their technologies at the event.

“Fiber optics is a game changer in the confrontation between communications and electronic warfare,” said Captain Oleksandr Yabchanka, head of the Da Vinci Wolves battalion’s robotic systems service. “We are very interested in introducing fiber optics so that our NRCs can operate at greater distances and help us destroy the enemy even more effectively.”

The Unmanned Systems Forces of Ukraine recently began testing domestic Silkworm fiber optic modules designed for aerial, ground, and maritime drones. These modules come in two variants: one with an integrated warhead and another with a built-in battery. FPV drones equipped with Silkworm modules maintain maneuverability and can cover distances exceeding 20 km. According to Ukrainian drone operators, fiber optic-controlled drones perform similarly to radio-controlled versions.

The cost of fiber optic drones has also decreased due to increased production, with prices expected to drop further for Ukrainian manufacturers. While China remains the primary supplier of fiber optic cable reels for both Russian and Ukrainian FPV drones, Ukraine has developed domestic production capabilities to ensure reliability and reduce the risk of cable breakage.

Ukrainian forces are actively deploying fiber-optic-controlled drones in combat, leveraging their enhanced range and resistance to electronic warfare.
