Russian forces are upgrading Shahed-type strike drones, known domestically as Geran-2, to counter Ukrainian electronic warfare more effectively amid intensified attacks since late 2024. Recent modifications, reported as of December 20, 2025, include Chinese-made 16-element antennas that resist up to 16 jamming sources, replacing earlier 4-element versions, and high-power Mesh modems enabling swarm communication over 200 km via daisy-chain networks. These enhancements, combined with warheads increased to 100 kg—including tandem high-explosive fragmentation types—boost lethality, as seen in strikes where more drones evade defenses. Ukrainian experts note the shift from mobile LTE reliance, now vulnerable to tracking, to resilient foreign-sourced tech despite sanctions. Over 27,000 such drones have been produced in Russia, altering tactics in the ongoing conflict.
