MOSCOW, July 7 — Ukrainian drone strikes on Russia’s largest oil refinery in late March 2025 marked a significant escalation in Kyiv’s campaign against Moscow’s energy infrastructure, according to official accounts and industry data. The attack on the Kirishi refinery, also known as Kinef, in Leningrad Oblast occurred on March 23, 2025. The facility, operated by Surgutneftegas, processes approximately 20 million tons of oil annually, representing roughly 5% of Russia’s total refining capacity, according to industry analysts.
The strike caused a fire at the site. Ukrainian President Volodymyr Zelenskyy, in a video address on March 24, 2025, stated that the strike demonstrates Ukraine’s growing reach, claiming that Siberia is now “within reach” of Ukrainian drones.
The Kirishi refinery is located approximately 700 kilometers from the Ukrainian border, while Siberia is over 3,000 kilometers away. Zelenskyy’s comments emphasized Ukraine’s development of long-range drone capabilities. The Russian Ministry of Defense reported that 25 drones were intercepted over Leningrad Oblast but acknowledged damage to the refinery.
Officials confirmed the incident, though specific details on the extent of the damage were not provided in the immediate aftermath. This attack is part of a broader campaign by Ukraine to disrupt Russian energy infrastructure, according to the record.
Since 2024, Ukrainian strikes have targeted refineries in Ryazan, Nizhny Novgorod, and Krasnodar Krai. The March 23 strike followed a series of Ukrainian drone attacks in March 2025, including a strike on the Syzran refinery in Samara Oblast on March 16, 2025, and the Novokuibyshevsk refinery on March 19, 2025. Industry analysts estimate that the attacks have reduced Russia’s primary oil refining capacity by an estimated 10-15% since early 2024.
The cumulative effect of these strikes represents a sustained effort to degrade Moscow’s war-fighting capability, according to the source material. The conflict, which began with Russia’s full-scale invasion of Ukraine on February 24, 2022, has seen Ukraine increasingly target strategic Russian infrastructure. The Kirishi refinery strike stands as one of the most significant such operations due to the facility’s size and its role in Russia’s domestic fuel supply.
Zelenskyy’s reference to Siberia being within reach, despite the distance exceeding 3,000 kilometers, signals Ukraine’s ambition to extend the range of its drone operations. The statement, made during a video address, underscores the technological development underway in Ukraine’s defense sector.
The March 2025 attacks on the Syzran and Novokuibyshevsk refineries in Samara Oblast, occurring within days of each other, indicate a pattern of concentrated strikes on Russia’s energy infrastructure. The Syzran refinery strike on March 16 and the Novokuibyshevsk refinery strike on March 19 preceded the Kirishi attack by less than a week. The Russian Ministry of Defense’s acknowledgment of damage to the Kirishi refinery, despite intercepting 25 drones over Leningrad Oblast, highlights the challenges in defending against such attacks.
The facility’s location approximately 700 kilometers from the Ukrainian border places it within range of Ukraine’s drone capabilities, though it remains deep inside Russian territory. Industry analysts have noted that the reduction in Russia’s primary oil refining capacity by an estimated 10-15% since early 2024 represents a significant operational impact.
The sustained campaign against refineries across multiple regions, including Ryazan, Nizhny Novgorod, and Krasnodar Krai, demonstrates Ukraine’s strategic focus on energy infrastructure as a means to affect Russia’s war effort. The Kirishi refinery, as Russia’s largest such facility, processes about 20 million tons of oil annually. The fire caused by the March 23 drone strike, while not fully detailed in official accounts, represents a direct hit on a critical node in Russia’s energy supply chain.
Looking ahead, the trajectory of Ukraine’s drone campaign against Russian oil infrastructure suggests continued operations aimed at further degrading refining capacity. The development of longer-range drones, as referenced by Zelenskyy, could extend the reach of future strikes deeper into Russian territory. The conflict’s dynamics, now in its fourth year, continue to evolve with Ukraine seeking to leverage technological advantages to offset Russia’s conventional military superiority.
