Why it matters
Ryazan is one of Russia’s largest oil refineries and supplies fuel for military vehicles and aviation. The strike could affect fuel availability for the Russian armed forces. Repeated attacks have left a substantial share of Russia’s refining capacity damaged, although they have not yet caused a nationwide fuel collapse.
What happened
Drones attacked the Ryazan Oil Refinery overnight into November 5, and a fire began on its grounds. The drone threat was declared in Ryazan Oblast at around 02:00 local time, after which residents reported multiple explosions, air defense activity, and the sound of drones. Astra OSINT analysts confirmed that the fire occurred at the refinery. The plant belongs to Rosneft and has an estimated capacity of about 17–18 million tonnes of oil per year. It produces gasoline, diesel, jet fuel, fuel oil, and bitumen, with its products supplied to Moscow and central Russian regions. It also manufactures fuel for the Russian Defense Ministry and TS-1 jet fuel used by Russian military aviation.
How Ukrainian sources describe it
Ukrainian outlets emphasize the refinery’s role in supplying aviation fuel, diesel, and TS-1 kerosene to Russian forces and military aviation. They also highlight the recurrence of strikes on Russian oil refineries and their cumulative effect on refining capacity, while noting that these attacks have not yet produced a fuel collapse.
Background
The Ryazan Oil Refinery is located in the Southern Industrial District of Ryazan and is one of Russia’s largest refining enterprises. It belongs to Rosneft and supplies central Russia, including Moscow. In 2014, the plant reported developing experimental batches of automotive gasoline specifically for the Russian Defense Ministry, manufactured to additional standards for use in Russian military vehicles. It also produces TS-1 jet fuel used by Russian military aviation. An earlier drone attack on October 15, 2026, caused a fire and halted the AT-6 and CDU-6 primary oil-processing units. Separately, Ukrainian drones attacked the Yaroslavl Slavneft-YANOS refinery overnight into November 3; it is another major Russian refinery producing fuel for military aviation and equipment.
