Russia has begun using long-range, jam-proof drones controlled by fiber-optic cables to threaten Ukraine's logistics, a senior government official told Business Insider. Mykhailo Fedorov, the first deputy prime minister of Ukraine and its minister of digital transformation, said that Russia is now fielding fiber-optic drones with a range of 50 kilometers (31 miles), which appears to be the first official confirmation from Kyiv that Moscow is using these weapons in combat. That 50-kilometer range exceeds what most known fiber-optic drones can achieve on the battlefield.
A drone attack on Kyiv and appearance of a cluster of drones over Polish territory in September 2025 has highlighted the threat posed by the rapid advancement of autonomous and uncrewed aerial vehicles. Drones provide a unique advantage for the world's militaries. For one, they are cheap to make, have been deployed in major conflicts, such as the Russia-Ukraine war, and efforts to defend against them are in a constant state of development.
