The Ukrainian military struck deep in Russia, attacking two key facilities of Russia's oil processing infrastructure. First, Ukrainian kamikaze drones attacked a Russian Lukoil oil refinery with over 60 drones. This is one of Russia's leading refineries, supplying Moscow Oblast, which accounts for about 30% of the country's petrol consumption. Its nominal crude processing capacity is about 17m tons per year. The plant produces over 50 types of products: petrol, aviation and diesel fuel, as well as bitumen, paraffin, and others. Second, commandos attacked the Sterlitamak Petrochemical Plant in Bashkortostan (more than 1,300 km away from the Ukrainian border), a major producer of components for aviation fuel, rubber and butylated hydroxytoluene. The plant plays a crucial role in Russia's military-industrial complex and is a significant source of revenue for the Russian state budget. Initial assessments indicate both attacks damaged the facilities, but the extent is unclear for now.
