Ukrainian forces struck Russia’s largest oil refinery in Omsk on Monday, marking the longest-range drone attack of the war at approximately 1,700 miles. The strike targeted a key processing unit at the Western Siberian facility, which processes about 21 million tons of oil annually, according to reports from the ground and official statements.
Omsk Governor Vitaly Khotsenko confirmed the attack on Monday, stating that “enemy UAVs” hit the refinery. While Khotsenko reported no immediate casualties, he warned the public to avoid approaching debris at the site. Social media footage and reports indicate a major fire broke out at the ELOU-AVT-11, a primary processing unit of the facility.
Ukraine’s Special Operations Forces (SOF) claimed responsibility for the operation via their Telegram channel, describing it as the “deepest long-range strike on enemy territory” since the full-scale invasion began. The SOF specifically identified the ELOU-AVT-11 as the “most important unit of the enterprise” and confirmed it sustained damage.
How did Ukrainian drones reach Siberia?
The strike was carried out using a new variant of the FP-1 drone, developed by the Ukrainian munitions firm Fire Point. Denys Shtilierman, the chief designer of Ukrainian munitions firm Fire Point, stated on X (formerly Twitter) that this latest jet-launched version of the drone can fly up to 2,110 miles. This significantly exceeds the 1,700-mile distance between Ukraine and Omsk.
The FP-1 is a fixed-wing, one-way attack platform. Previous iterations of the drone carried a payload of up to 60 kg with a range that grew from 1,000 miles to 1,600 miles. The new variant’s extended range allows Ukraine to target strategic infrastructure deep within Russian territory, a development President Volodymyr Zelenskyy called an “important achievement” during his nightly address, noting that “upgraded Firepoint drones have put Siberia within reach of Ukrainian precision.”

What is the impact on Russia’s oil refining capacity?
This attack is part of a broader Ukrainian strategy to degrade Russia’s energy infrastructure. Since March, Kyiv has reported over 50 attacks against Russian oil facilities. According to the General Staff of the Armed Forces of Ukraine, these operations have hit approximately 42% of Russia’s total oil refining capacity.
The cumulative effect of these strikes has led to domestic fuel instability. Official government figures indicate that national gasoline production dropped 17% to 850,000 barrels a day. Consequently, more than half of Russia’s 83 regions have implemented fuel rationing in recent weeks.
Vladimir Putin acknowledged the existence of fuel shortages earlier this month, though he characterized them as “temporary” and “not critical.” To counter these long-range threats, Putin stated that Moscow intends to rapidly increase the production of air defense systems to protect refineries across the country.
Why the Omsk refinery is a strategic target
The Omsk refinery is the largest in Russia, making it a critical node in the country’s economic and military logistics. By targeting the ELOU-AVT-11 unit, Ukraine aimed to disable the most vital part of the refinery’s processing chain.
The use of drones over traditional missiles for these strikes reflects a cost-benefit strategy. While drones are slower than missiles, they are significantly cheaper to produce and deploy in large numbers, allowing Ukraine to maintain a high tempo of strikes.
Governor Khotsenko’s office has focused on public safety warnings rather than specific repair timelines or production loss figures.
This story will be updated as more data on the refinery's operational status becomes available.
