**Deck**: A Ukrainian drone strike on 6 September added fresh damage to Russia’s third‑largest oil refinery at Ryazan, which analysts say is already under constant repair.

Ukraine has again targeted one of Russia’s most important fuel plants, adding to a pattern of hits that keep a major refinery in near‑permanent repair.

Satellite footage shared by Exilenova+ shows new damage at the Ryazan Oil Refinery following a Ukrainian strike on 6 September. The facility, southeast of Moscow, is Russia’s third‑largest refinery by design capacity at about 18.8 million tons annually and is described as remaining under constant repairs.

The imagery indicates that crude distillation units AVT‑3 and AVT‑4 are still being repaired from earlier strikes, while new damage from the latest attack is assessed as likely. Full details of the new impact have not yet been catalogued.

The repeated hits mean Ryazan is operating below its design capacity and relying on extended repair work to stay online. That constrains how much fuel it can produce while it is already coping with earlier damage.

Inside Ukraine, fuel prices have been rising, with reporting noting that premium diesel is already looking toward the 100‑hryvnia mark per liter. While that increase is driven by wider market pressures, Ukrainian planners also see refinery strikes inside Russia as a way to add cost and complexity to Moscow’s war effort.

The Ryazan attack fits into a broader Ukrainian campaign using drones against refineries and energy infrastructure across western Russia, aiming to push the conflict deeper into Russia’s rear and to treat fuel production as a military‑relevant target.

Signals to watch include further satellite imagery of Ryazan and other struck refineries, any reports of adjustments to Russian refined‑product exports, and visible changes in Russian domestic fuel pricing or distribution.
