Ukraine’s Security Service (SBU) deployed at least eight long-range drones to strike the Cherkasy Linear Production and Dispatch Station in Bashkortostan, reaching 1,500 km deep into Russian territory. The attack ignited fires at the tank farm and production facilities of this key Transneft-Ural node, which annually transports nearly 2 million tons of petroleum products from the Ufa refining hub. This record-distance operation, executed under President Zelenskyy’s standing directive to degrade Russia’s military-economic potential, disrupts fuel logistics across western Russia. The strike coincides with broader overnight strikes on Saratov refinery, TANECO, TAIF-NK, and shadow fleet tankers. No official Russian damage assessment or casualty count has been released, leaving operational disruption levels unconfirmed by independent sources.
