**Deck**: Ukrainian long‑range drones struck the Ilsky Oil Refinery in Russia’s Krasnodar Krai and prompted a shutdown at the large Perm refinery after a fire and damage to pipelines and processing units. Both plants help fuel Russia’s war effort, turning core energy infrastructure into a contested frontline asset.

Ukrainian forces are extending their campaign against Russian fuel infrastructure, with long‑range drones striking two major refineries that help supply Russia’s war effort.

In Russia’s Krasnodar Krai, Ukrainian long‑range drones hit the Ilsky Oil Refinery, where fires were reported at the facility. The refinery has six primary refining units and a capacity of roughly 6.6 million tons of crude per year. It produces diesel, gasoline, fuel oil and bitumen. Its products support Russian military logistics in the Southern Military District and in occupied Ukrainian territories, so damage there reaches beyond a single plant and into the fuel chain feeding forces in the south.

Further north, Russia’s Perm oil refinery, described as one of the country’s largest, halted operations after a Ukrainian drone attack caused a fire and damaged pipelines, storage facilities and processing units, according to a Reuters report. Shutting a plant of this scale, even temporarily, interrupts fuel flows and forces Russian planners to change supply routes and draw down stocks for both civilian and military users.

Fuel from refineries like Ilsky and Perm moves by pipeline, rail and road to depots closer to the front, then on to armored vehicles, trucks and generators. Disruptions at large refineries can add delays and complications at every step of that chain.

For Russia’s wider economy, refinery outages can bring regional fuel shortages, price pressures or limits on industrial customers. The specific economic impact of these strikes is not yet clear, but repeated hits on refineries push Russian authorities to decide how much to spend on air defenses around energy sites, on repairs, and on building backup capacity.

The attacks underline how Ukraine is using long‑range drones to reach deep into Russian territory. Such drones are cheaper than cruise missiles and can be built in quantity inside Ukraine, which allows sustained pressure on strategic targets and exposes gaps in Russian air defenses far from the frontline.

Energy sites, alongside power plants, rail nodes and bridges, have become regular targets in the war. Strikes on Ilsky and Perm in close succession show refineries remain prominent in that target set, with added risks of industrial accidents and pollution in Russian regions that were not originally designed to operate under regular attack.

Key questions now are how fast operations at Perm can restart, what Russian officials disclose about the scale of damage at Ilsky, and whether more Ukrainian drones soon target other refineries, export terminals or storage hubs. Those signals will show whether this is turning into a sustained campaign against Russia’s refining capacity.
