The Next Evolution in Ukraine’s Drone Defense |
As Russia’s invasion of Ukraine approaches its fifth year, the character of the war continues to evolve into a technical struggle shaped by drones, electronic warfare, and the ability to strike at depth.
Ukraine has compensated for its disadvantage in traditional firepower through innovation. Unmanned systems, particularly first-person-view (FPV) drones, allowed Ukrainian forces to blunt Russian offensives and impose high costs on attacking units. Over time, this approach hardened into a “drone wall,” a layered defensive zone that has turned many Russian assaults into fields of casualties.
That kill zone has expanded steadily, now stretching roughly 15 to 25 kilometers from the front line, with Ukrainian forces increasingly pushing its reach up to 40 kilometers.
In April 2025, I wrote that Ukraine had established its drone wall defenses and that a new kind of no man’s land was emerging. Battlefields would increasingly be saturated with semi-autonomous drones capable of detecting and striking exposed movement, foreshadowing the direction of automated warfare.
But it is also increasingly clear that it is not decisive, especially as warnings grow that Ukrainian units lack enough drones. “There are pilot groups who sit idle 80 percent of the time because they don’t have enough drones,” said Dimko Zhluktenko of the 413th Separate Battalion of Unmanned Systems. Defense Minister Denys Shmyhal stated that Ukraine’s Armed Forces are expected to receive 3 million FPV drones by the end of 2025.
Even so, production must scale up faster as demand grows across the front, and multiple Ukrainian drone units are operating under persistent shortages against the Russian meatgrinder operation.
Throughout 2025, Russia has adapted and learned from its mistakes. Moscow has narrowed Ukraine’s early drone advantage by accepting heavy infantry losses while relocating critical assets deeper behind the front. The establishment of the Rubicon drone formation has also played an important role. Artillery, air defenses, and command-and-control nodes have been moved beyond the range of most short-range strike systems and placed under dense electronic warfare protection.
This tradeoff has been enabled by Russia’s rapid maturation of counter-drone capabilities. As defense analyst Justin Bronk of the Royal United Services Institute notes, after years of intensive combat, Russian forces now field layered electronic warfare, short-range air defenses, infantry counter-drone training, and physical hardening measures that significantly reduce the effectiveness of massed drone strikes.
