Ukrainian drones hit the Moscow oil refinery in Kapotnya on May 17, forcing a temporary shutdown of one of Russia’s most strategically important fuel processing facilities. The refinery, operated by energy giant Gazpromneft, sits inside Moscow’s city limits, making the strike one of the most symbolically significant attacks of the entire conflict.
This wasn’t a one-off. The Kapotnya strike was part of a broader campaign in May 2026 that also hit refineries in Volgograd, Saratov, and Ryazan, collectively reducing Russian oil refining capacity by an estimated 20-33% in central Russia.
A systematic campaign against Russian energy
Ukrainian officials have been open about the strategy. Andriy Kovalenko, a Ukrainian official, confirmed damage at multiple refineries, including the previously targeted Afipsky facility.
The Russian Defense Ministry pushed back with its own narrative, claiming to have intercepted hundreds of incoming drones. Figures cited by Moscow ranged from 216 to 330 drones intercepted in individual incidents.
