Ukraine strikes disable over half of Russia's oil refining capacity, Defense Ministry says

Key facts

• Over 51% of Russia's oil refining capacity has been disabled by Ukrainian attacks, according to Ukraine's Defense Ministry.
• Kyiv considers oil refineries valid military targets as they supply fuel and funds to the Russian armed forces.
• Recent attacks targeted refineries in Moscow, Yaroslavl, Kirishi, Perm, Ilsky, Saratov, and Syzran.
• Ukraine's Defense Ministry reported a tripling of its production and procurement of long-range strike drones in 2026.

Ukrainian attacks have disabled more than 51% of Russia's oil refining capacity, according to a report from Ukraine's Defense Ministry on October 4. The strikes are part of a broader campaign targeting Russia's energy infrastructure to cripple its war machine and economy.

Kyiv views oil refineries as legitimate military targets, as they provide fuel and financial resources to the Russian armed forces. Defense Minister Yevhen Khmara stated that the damage represents a significant blow to Russia's economy and its ability to wage aggression.

The ministry's assessment marks an increase from the 45% drop in Russian refining capacity previously reported by Ukraine's General Staff on September 21. This escalation follows a decree signed by Russian President Vladimir Putin on September 28, which restricts access to data concerning the country's oil refineries and energy exports amidst Ukraine's intensified strikes.

Ukraine's long-range strike drones and missiles have demonstrated the capability to consistently reach targets over 1,500 kilometers from Ukrainian-controlled territory. A Fire Point FP-1 drone reportedly struck a Russian gas facility 3,200 kilometers from the Ukrainian border on September 9, setting a new record for distance.

Ukraine's Defense Ministry also reported on October 4 that it has tripled its production and procurement of long-range strike drones in 2026 and aims for continued growth in its long-range strike capabilities.
