Ukraine Hit Two of Russia's Five Largest Refineries. Both Are 700 Kilometers Behind the Front.

On March 28, Ukrainian drones struck the Slavneft-YANOS refinery in Yaroslavl, one of Russia's five largest refineries. Fires broke out in three separate areas of the facility. The refinery sits approximately 700 kilometers from Ukrainian-controlled territory. Two days earlier, on March 26, Ukrainian drones hit the Kirishi refinery near St. Petersburg, Russia's second-largest by throughput.

Two of Russia's top five refineries hit in three days. Both deep inside Russian territory. Both beyond the range of any weapon Ukraine was using a year ago. The fiber-optic FPV drone revolution and long-range strike drone programs have extended Ukraine's reach to targets that were considered safe 12 months ago.

Russia's refining capacity is degrading. The cumulative effect of months of deep strikes is measurable: Russian refined fuel exports have declined approximately 15-20% since Ukraine began systematically targeting refineries in 2024. Each refinery hit requires weeks to months of repair. The Slavneft-YANOS fires in three areas suggest multiple entry points or multiple drones, complicating repair timelines.

The Russia-Iran feedback loop runs in both directions. Russia sends drone tactics to Iran. Ukraine sends drone tactics against Russia. The weapons that Russia deploys against Ukrainian cities are being answered by weapons that reach 700 km into Russian industrial heartland. The asymmetry works both ways.

FAQ

How is Ukraine hitting targets 700km away?

Long-range strike drones (not the $500 FPV type). Ukraine has developed indigenous long-range drones with ranges exceeding 1,000 km. The exact type used at Yaroslavl is not confirmed but fits the profile of the Beaver or similar Ukrainian-designed platforms. These are more expensive than FPV drones ($50,000-200,000 each) but dramatically cheaper than cruise missiles.

Can Russia defend its refineries?

Partially. Russia has deployed Pantsir-S1 and Tor-M2 air defense around critical infrastructure since 2024. The defenses intercept many incoming drones. But the attack volume exceeds the defense capacity. If Ukraine sends 10 drones at a refinery and 7 are intercepted, 3 get through. Three hits on a refinery are enough to start fires and shut down processing units.

Does this affect Russian oil production?

Not production (which comes from wells) but refining. Russia must export crude instead of refined products, losing the refining margin. It also creates domestic fuel shortages that require the government to restrict fuel exports. The economic impact compounds over time as more refineries accumulate damage that takes months to repair.
