Ukraine's drone campaign has crippled one-third of Russia's refining capacity in a year

Ukrainian long-range drones have systematically disabled roughly one-third of Russia's operational oil refining capacity since August 2025, inflicting $13.5 billion in cumulative losses on the energy sector. The campaign includes eight refineries hit in June alone and over 60 storage tanks destroyed or damaged. Moscow has responded by extending export bans and restricting fuel sales across 40+ regions. Putin acknowledged shortages but downplayed severity. Repair timelines extending into 2027 suggest the damage will compound before full recovery.
