It’s no secret that Ukrainian soldiers are developing cutting-edge technologies that are changing the rules of the game on the battlefield. Among these innovations are fiber-optic-controlled FPV drones, which have virtually no analogs in the world. Their uniqueness lies in their resistance to electronic warfare (EW) measures, making them an effective weapon on the front lines.
Soldiers from the 93rd Separate Mechanized Brigade “Kholodny Yar” shared their experience using fiber-optic drones, discussing their advantages and drawbacks in a video on the brigade’s channel.
A fighter with the call sign “Omar,” along with his comrade “Shyba,” operates these drones directly from a bunker just a few kilometers from the front line. One of their latest missions was the destruction of an enemy drone operator position, which they managed to locate thanks to an antenna that amplified the signal.

When the fiber-optic FPV drone reached its target, it achieved a double hit—the soldiers not only eliminated enemy UAV operators but also detonated an ammunition depot. The successful attack once again demonstrated the superiority of these drones, which cannot be jammed, while the operator receives a stable and clear video feed.
“An FPV drone is like a mischievous child. You have to babysit it,” jokes Omar. In the past, he and Shyba used Soviet-era wire-guided anti-tank missiles to destroy enemy equipment. Now, they employ a new tactic—guiding FPV drones to their targets via fiber-optic cable.
Thanks to this technology, the drone can fly into low-altitude areas, making it difficult for enemy air defense systems to intercept. The operator’s “goggles” provide a clear image, allowing for precise strikes. Only two armies in the world—Ukraine’s and Russia’s—currently use such drones, making this technological battle even more intense.
Shortly after the report was filmed, Omar himself became a victim of an enemy FPV drone. He and Shyba were pursued by an enemy “FPV kamikaze” on a quad bike. As a result of the attack, Omar suffered shrapnel wounds to his legs, a severe concussion, and a ruptured eardrum. Despite his injuries, he is already eager to return to his comrades, who continue to destroy the enemy near Klishchiivka.
Unstoppable Signal: The Advantages and Challenges of Fiber-Optic FPV Drones in Combat
Fiber-optic drones are not just advanced weaponry; they are also the result of dedicated work by enthusiasts. Soldiers build and modify them directly on the front lines. For instance, “closing whiskers” are made from bicycle spokes, while wire spools are designed in Ukraine. These drones have a payload capacity of up to 3 kg and an operational range of up to 10 km.
However, this technology has its drawbacks: the drones are large, and the wire spool is a vulnerable point. A single pellet is enough to damage the mechanism. Additionally, the operator must account for wind direction and fiber placement to prevent entanglement.
Despite these risks and challenges, the effectiveness of these drones has been proven on the battlefield. The enemy has become more cautious—Russians no longer move as boldly, their logistics have become more complicated, and ammunition deliveries have become problematic.
“Fiber Optics vs. Electronic Warfare”: How Defense Forces UAV Operators Use Next-Gen Drones
The 63rd Brigade of the Ukrainian Armed Forces has started using fiber-optic drones, ensuring stable communication and uninterrupted transmission for operators.
More details about the advantages and operational features of this type of drone can be seen in Lieutenant Serhii Lipko’s report on Army TV.
The commander of the UAV systems platoon of the 63rd Separate Mechanized Brigade, call sign “King,” explained that the key benefits of fiber-optic drones are uninterrupted video feed for the operator and immunity to enemy electronic warfare (EW) systems.
“A drone isn’t something overly complex,” says King. “It could have been produced earlier. But it solves two very serious problems for us: first, electronic warfare; second, the terrain in our sector is highly uneven. The drone needs to fly into lowlands, navigate forests, and avoid several obstacles on its way to the bunker. We’ve lost many drones simply because the analog signal was disrupted due to poor radio line-of-sight. But with fiber optics, there’s no radio horizon—everything is transmitted via cable.”
According to King, fiber-optic transmission ensures a perfect image even when flying directly over enemy trenches. He also noted that the drone can be used in forests without the risk of getting caught on tree branches.

However, fiber-optic drones also have their downsides. They are larger and less maneuverable, making them an easier target for the enemy. The only way to counter these drones is through physical destruction using small arms or other munitions.
“If it slows down and starts approaching the target, the chances of shooting it down increase significantly,” says King.
