Operation Spiderweb

Operation Spiderweb (Ukrainian: Операція «Павутина», romanized: Operátsija "Pavutýna") was a covert drone attack carried out by the Security Service of Ukraine (SBU) deep inside Russia on 1 June 2025, during the Russo-Ukrainian War. The coordinated strikes targeted the Russian Air Force's Long-Range Aviation assets at five air bases — Belaya, Dyagilevo, Ivanovo Severny, Olenya, and Ukrainka — using drones concealed in and launched from trucks on Russian territory.

It was the largest drone attack on Russian air bases up to that point in the war, employing 117 drones, according to Ukrainian officials. According to two US officials speaking to Reuters, about twenty military aircraft were hit in the attack, ten of which were destroyed. Russia confirmed that the attack took place. The operation was notable for its unprecedented geographical reach — spanning five oblasts across five time zones — particularly the strike on Belaya Air Base in Eastern Siberia, where damage was confirmed 4,300 km (2,700 mi) from Ukraine.
