Ukrainian drones strike Kuibyshevsky refinery in Russia's Samara region, fire burns into next day
Ukraine's Unmanned Systems Forces struck the Kuibyshevsky oil refinery in Russia's Samara region, more than 1,000 km from the launch point, with a fire still burning on September 22, 2026. Ukraine's General Staff also confirmed a simultaneous strike on the Bashneft-UNPZ refinery in Ufa.
Key points
- Strike carried out by operators of the 1st Separate Center of the Unmanned Systems Forces together with other Defense Forces components
- Distance to the Kuibyshevsky refinery target was over 1,000 km, according to the Unmanned Systems Forces
- Smoke from the fire at the refinery stretched for 100 km, according to the Ukrainian OSINT channel Exilenova+
- Kuibyshevsky refinery is one of the largest in the Samara group and belongs to PJSC NK Rosneft, with processing capacity of approximately 7 million tons of oil per year
- The refinery produces gasoline, diesel, fuel oil, and more than 30 other petroleum products, some used by the Russian army
- On the same date Ukraine's General Staff confirmed a strike on the Bashneft-UNPZ refinery in Ufa; the two plants together process about 15 million tons of oil per year
Why it matters
The strike demonstrates the extended range of Ukraine's unmanned systems forces, hitting one of Russia's largest refineries more than 1,000 km inside Russian territory. Damage to a facility that produces fuel products used by the Russian military can affect Russian war-fighting capacity. Confirmation of two major refinery strikes on the same date signals an expanding campaign against Russian energy infrastructure.
What happened
On September 22, 2026, Ukraine's General Staff confirmed that the Defense Forces had struck the Kuibyshevsky oil refinery in Russia's Samara region the night before. The strike was carried out by operators of the 1st Separate Center of the Unmanned Systems Forces together with other components of the Defense Forces, at a distance of over 1,000 km from the launch point. A fire broke out at the refinery and was still burning the following day; the Ukrainian OSINT channel Exilenova+ reported that smoke from the blaze stretched for 100 km. The General Staff also confirmed a simultaneous strike on the Bashneft-UNPZ refinery in Ufa, the capital of Bashkortostan, where drones also caused a fire. The Kuibyshevsky refinery is part of the Samara group and belongs to the structure of PJSC NK Rosneft, with processing capacity of approximately 7 million tons of oil per year and an output that includes gasoline, diesel, fuel oil and more than 30 other petroleum products, some of which are used by the Russian army. Bashneft-UNPZ processes approximately 7.5 million tonnes per year, bringing the combined capacity of the two struck facilities to almost 15 million tonnes annually.
How Ukrainian sources describe it
Ukrainian sources frame the operation as a significant operational achievement. Reporting names the 1st Separate Center of the Unmanned Systems Forces, highlights the more than 1,000 km range, and uses the 100 km smoke plume reported by Exilenova+ to underscore the impact. The Kuibyshevsky refinery is described in terms of its strategic value to Russia: Rosneft ownership, approximately 7 million tons per year of processing capacity, and output that includes fuel products used by the Russian army.
