Ukrainian drones have struck nearly every major Russian refinery. Which facilities have yet to be hit?

Key Points:

• Ukrainian forces have systematically targeted major Russian oil refineries, striking nearly all key facilities in the European part of Russia multiple times by May 2026, causing significant production cuts and a nationwide fuel crisis.
• Among Russia’s largest refineries, only the Omsk Oil Refinery and Angarsk Petrochemical Company, both located beyond the Urals, have not been struck by Ukrainian drone attacks as of late June 2026.
• The Omsk region has responded to the fuel shortage by banning fuel sales in canisters and limiting gasoline purchases to 40 liters per fill-up, while the Irkutsk region declared a state of heightened readiness due to the gasoline crisis.
• Ukrainian drone strikes have not yet reached refineries in the Russian Far East and Eastern Siberia, where local facilities are insufficient to meet regional fuel demands.
• The Omsk region issued a drone attack alert in June 2026 for the first time since the war began, but no strikes or drone interceptions were reported on that day.
