Ukraine's Unmanned Systems Forces, alongside special operations units, struck the Ryazan oil refinery — one of Russia's four largest — and an oil depot in occupied Luhansk Oblast.
Overnight on September 5, units of Ukraine's Unmanned Systems Forces, together with Special Operations Forces, Defense Intelligence and other formations, struck the Ryazan oil refinery in Russia — one of the country's four largest plants. The same day, Ukraine's defense forces reported hitting an oil depot in temporarily occupied Luhansk Oblast. Volunteers Support Ukraine notes that operations like these chip away at Russia's ability to fund the war with fuel revenue.
The Ryazan plant processes roughly 13.1 million metric tons of crude oil a year — nearly 5% of Russia's entire refining capacity. Reports say the drone strikes sparked a fire at the facility, and the plant's operator later confirmed that some units had suspended operations. The strike was carried out by the 14th Unmanned Systems Regiment together with special operations and intelligence units.

The same day, Ukraine's defense forces struck an oil depot in temporarily occupied Luhansk Oblast — another link in the logistics chain that keeps Russia's military machine fueled. Strikes like this on oil infrastructure have become a systematic part of Ukraine's strategy to erode the occupier's capabilities.

Oil products are one of the Kremlin's key sources of foreign currency, which finance the war directly. Ukrainian long-range drones have regularly hit refineries across Russia in recent months — from Krasnodar Krai to Tatarstan — forcing the industry to spend resources on repairs instead of ramping up supplies for the front.

Volunteers Support Ukraine continues to follow the course of the war and help people affected by it in whatever way its available resources allow, believing that every strike on the enemy's war machine brings closer the day Ukrainians can live without fear of new attacks.
