Ukraine claimed a 2,500km deep strike on the Omsk refinery in Siberia on 6 July, describing it as its longest one-way drone strike of the war1. The range and the world-record framing rest on Ukrainian sources, and the damage at the site is reported separately, so the distance is Kyiv's assertion rather than a settled fact. Omsk lies roughly 2,500km east of the Ukrainian border, deep in Russia's interior.
The strike belongs to the same campaign as Russia's own scramble to protect its fuel supply. Moscow imposed a producer-binding diesel export ban in early July, and Ukraine's deep-strike programme is aimed at the refining capacity that ban is meant to ration. Both moves target the same bottleneck from opposite directions.
A refinery 2,500km from the front cannot be defended the way border-region plants are, so extending the strike map that far east forces Russia to thin its air defences across a vastly larger interior, or accept that no refinery is now safely out of reach.
