The newspaper *Financial Times*, citing its own analysis and data from the Polish analytical group Rochan Consulting, reports that since the beginning of the year, Russian oil refineries have been subjected to at least 194 successful attacks by Ukrainian drones. According to the publication's estimates, this is about 11 times more than during the same period last year. The most intense month was May, when analysts recorded 16 successful strikes on oil refineries — the highest monthly figure since the beginning of the year. According to *Financial Times*, the statistics on attacks and interceptions indicate not only an increase in the number of drone launches but also a rise in the share of devices that manage to reach their intended targets. This suggests that the Ukrainian campaign of strikes on Russian energy infrastructure is becoming more extensive and effective. One of its goals is believed to be creating additional difficulties for Russia's fuel sector. Sources for the publication attribute this dynamic to several factors. In their opinion, Ukraine has significantly increased the production of long-range drones, established their serial production, and improved the efficiency of operation planning. Furthermore, *Financial Times* writes that support from American intelligence agencies played an important role. According to the publication, they helped identify optimal flight routes for drones, allowing them to bypass Russian air defense systems. Stefan Meister, head of the Eurasian Program at the German Council on Foreign Relations, told the newspaper that Ukraine has achieved a technological breakthrough in the production of long-range drones, which has allowed for a significant increase in the scale of such operations. The publication of *Financial Times* is based on analytical assessments of open data and reflects the authors' conclusions about the dynamics of strikes on Russian oil refining infrastructure.
