Ukrainian forces conducted a record series of drone strikes against Russian oil refineries during May [1].
These operations target the fuel resources necessary for Russian military movements. By degrading refining capacity, Ukraine aims to disrupt the logistics and operational readiness of forces engaged in the conflict.
According to reports, Ukrainian drone systems carried out 30 strikes on oil infrastructure throughout May [1]. This campaign has caused a sharp decline in Russia's ability to process crude oil. The total oil processing capacity in Russia has fallen to levels last seen in 2009 [1].
The impact of these strikes has extended beyond industrial output to affect civilian and military administration in contested areas. In occupied Crimea, the shortage of available fuel has led to the introduction of fuel vouchers [1].
These strikes target a critical node of the Russian economy, the energy sector, to limit the amount of refined petroleum available for the war effort. The use of long-range drone systems allows Ukrainian forces to hit targets deep within Russian territory and the Crimean peninsula [1].

The reduction of Russian oil processing to 2009 levels suggests a significant degradation of industrial resilience. The implementation of fuel vouchers in Crimea indicates that the supply chain disruptions are severe enough to require rationing, potentially hindering both local governance and the mobility of military assets in the region.
