From fall 2025 through spring 2026, the words “aerostat notice” have appeared hundreds of times on Russian Telegram channels that monitor Ukrainian air threats.
Over 1,000 Ukrainian balloons have drifted east into Russia since fall 2025. A skilled team can deploy one in 15 minutes. At least one went 4,000 km deep into Russian airspace.
They carry retroreflective decoys, surveillance equipment, bombs, attack drones, or radio repeaters that help with long-range drone guidance. They have been instrumental in attacks on refineries, railways, and other high-value targets.
While inconspicuous and hard to pick up on radar, the trick isn't always to hide— Russian crews unload Pantsirs, Tors, Buks, even S-400 missiles at these aerostats, especially when they drift around sensitive areas like Moscow.
This cheap, simple technology, taking advantage of prevailing winds that blow towards Russia, is on the rise among Ukrainian forces.
