Drone Strike Shuts Russia’s Syzran Oil Refinery for Over a Month

A Ukrainian drone hit Syzran refinery's CDU-6 distillation unit (Rosneft, 170,000 bpd) on May 21, halting over 70% of its capacity for at least a month. Kyiv's sustained campaign now disrupts ~25% of Russia's total refining capacity, signaling a structural degradation of Russian fuel export volumes.
