Ukraine has successfully tested long-range First-Person View (FPV) drones using fibre optic control systems, marking a significant advancement in unmanned aerial technology. The tests, conducted by the Brave1 state defence technology cluster, were supported by Brigadier General Andriy Lebedenko, the Deputy Commander-in-Chief of the Armed Forces of Ukraine, and the Innovation Directorate of the Ukrainian Armed Forces. The trials took place at a specially designated training ground, where over 15 manufacturers of unmanned aerial vehicles (UAVs) tested their systems over a 20-kilometre obstacle course, simulating target attacks.
Previously, the range of such drones was limited to 5-10 kilometres, but Ukrainian engineers have now developed models capable of engaging targets at distances exceeding 20 kilometres. This improvement significantly enhances Ukraine’s ability to conduct long-range strikes, a capability that was previously achieved with radio-controlled drones. The introduction of fibre optic control systems ensures that these drones can carry out missions while being resistant to electronic interference, a critical advantage on the modern battlefield. The absence of radio emissions from fibre optic cables makes these drones nearly undetectable by enemy radio reconnaissance, further strengthening their operational security.
Moreover, operators benefit from high-quality imagery, unaffected by radio noise, and the drones are shielded from electronic warfare attacks that often disrupt conventional radio-controlled systems. During the tests, the participants also showcased seven different ground robotic systems controlled by fibre optics, demonstrating the versatility of this technology in both aerial and ground operations. Captain Oleksandr Yabchanka, head of the Da Vinci Wolves battalion’s robotic systems service, remarked that fibre optics was a “game changer” in the ongoing confrontation, as it allows Ukrainian forces to operate at greater distances and enhance strike effectiveness.
This development follows an earlier announcement in February, when Ukraine began testing Silkworm fibre optic modules. These modules, designed for installation on air, ground, and sea drones, are already showing promising results. There are two versions of the Silkworm: one equipped with a warhead for kamikaze missions and the other with a built-in battery for extended operation. The drones equipped with Silkworm modules maintain excellent manoeuvrability and can cover more than 20 kilometres without suffering from the limitations of traditional radio-controlled systems.
The cost of fibre optic drones has also dropped significantly, with production ramping up in Ukraine, making them more accessible for local companies. China currently leads the market in supplying fibre optic cables for drones, with both Russian and Ukrainian manufacturers relying on Chinese components. Ukraine, however, has developed the necessary infrastructure to spool fibre optics locally, reducing the risks of cable breakage during flight and ensuring better reliability in combat conditions.
