**Deck**: At around 06:05 UTC on 22 May, Ukrainian sources reported that at least 24 of 33 large oil refineries in the European part of Russia have been attacked since the start of the campaign, with an estimated 158 strikes. Only a few major plants east of the Urals remain untouched.

## Key Takeaways
- By 06:05 UTC on 22 May 2026, Ukraine reported attacks on at least 24 of 33 large refineries in European Russia.
- An estimated 158 strikes have targeted Russian refining capacity over time, leaving only major plants in Omsk and Angarsk east of the Urals unhit.
- The campaign indicates a sustained Ukrainian effort to degrade Russia’s fuel production, logistics, and wartime economy.
- The attacks raise the risk of Russian retaliation and have potential implications for global fuel markets.

At approximately 06:05 UTC on 22 May 2026, Ukrainian military-linked reporting stated that Ukraine has carried out a systematic campaign against Russian oil refining infrastructure in the European part of the country. According to these claims, at least 24 out of 33 Russian refineries with annual capacities exceeding 1 million tons of oil have been struck, with a cumulative total of around 158 individual attacks. The reporting emphasized that among Russia’s largest refineries, only the Omsk and Angarsk plants, both located east of the Ural Mountains, remain outside the strike zone.

Although exact dates for each strike are not specified in the report, the aggregate numbers indicate a prolonged and escalating campaign. Ukraine’s use of long-range drones and possibly other strike systems to reach deep into Russian territory reflects both technological adaptation and a strategic choice to target the industrial backbone sustaining Russian military operations.

Russian refineries are crucial nodes in the country’s domestic fuel supply chain and export revenues. By focusing on facilities in European Russia—closer to key military districts, logistics hubs, and export terminals—Ukraine appears intent on imposing operational friction on the Russian Armed Forces, limiting availability of aviation fuel, diesel, and other refined products needed for large-scale military operations. The reference to the Omsk and Angarsk refineries remaining beyond the current strike envelope implicitly underlines the range limitations and risk calculus shaping Ukrainian operations.

Key players in this dynamic include Ukraine’s defense and intelligence services, which are adapting unmanned aerial and possibly stand-off strike capabilities to overcome Russian air defenses; Russian energy majors and regional authorities responsible for maintaining and repairing the targeted facilities; and the Russian military, which depends on stable fuel supplies. Western technical and intelligence support to Ukraine, while not explicitly cited in the report, is likely a factor in enabling target identification and strike effectiveness.

The campaign matters for several reasons. Militarily, repeated strikes on refineries can force Russia to reroute fuel from more distant facilities, increase transportation costs and delays, and complicate force posture decisions near the front. Economically, damaged or disrupted refining capacity can reduce export volumes of refined products, affect domestic fuel prices, and require costly repairs under sanctions-constrained conditions.

Politically and diplomatically, Ukrainian strikes deep inside Russia heighten escalation concerns and fuel debates among Kyiv’s Western partners over how Ukrainian long-range strike capabilities should be employed. Moscow can leverage such attacks in domestic messaging to justify intensified military operations or broader mobilization measures. At the same time, Ukraine frames these actions as legitimate efforts to degrade the infrastructure directly supporting Russian military aggression.

Globally, any sustained reduction in Russian refined product exports—especially diesel—could tighten international markets, particularly in Europe and parts of Africa and Latin America that still rely on Russian supply. However, the net impact will depend on the balance between damage, repair, and Russian ability to compensate via unaffected refineries, including those east of the Urals.

## Outlook & Way Forward

In the near term, further Ukrainian strikes against Russian energy infrastructure are likely, particularly if Kyiv assesses that these operations are imposing significant costs on Russian logistics and industry. Russia can be expected to enhance air defenses around critical facilities, deploy additional electronic warfare measures to disrupt drones, and adjust fuel distribution patterns to reduce vulnerability.

The potential for escalation remains significant. Russia could respond with more concentrated strikes on Ukrainian energy and industrial infrastructure or attempt cyber operations against Ukraine’s and allied energy systems. Western capitals will continue to scrutinize the strategic utility versus escalation risk of deep-strike campaigns, especially if attacks impact Russian civilian energy supply.

Strategically, the refinery strike campaign illustrates how the conflict is increasingly targeting each side’s economic and industrial depth, not just front-line forces. Observers should watch for evidence of lasting reductions in Russian refining output, changes in Russian fuel export flows, and any policy shifts by Ukraine’s partners regarding the provision or use of long-range strike capabilities. The trajectory of this campaign will be a key indicator of how both sides envision the war’s economic front over the coming year.
