Russia Fortifies Refineries with Anti-Drone Nets Amid Intensifying Ukrainian Strikes; Western Vulnerabilities Exposed

Russian energy companies, including Rosneft, have deployed improvised passive defenses such as netting, steel cables, scaffolding, and shipping container walls around oil storage tanks and processing units at refineries across the country. Satellite imagery from firms like Vantor and reports from Business Insider and Forbes confirm these measures at sites including the Kuybyshevskiy refinery and others in Samara, Velikiye Luki, and near Moscow, implemented in response to repeated Ukrainian long-range drone attacks that have damaged or disrupted operations at over 20 major facilities in 2025-2026. Leaked internal documents analyzed by Defence24 detail ad-hoc multi-layer protections designed to intercept or mitigate low-flying drones, though Ukrainian swarms have frequently overwhelmed them, as seen in strikes on Moscow's Kapotnya refinery and others where netting failed to prevent fires and throughput drops. The International Energy Agency notes that these attacks have reduced Russian refining capacity significantly, with throughput hitting multi-year lows and prompting export bans on fuels. This defensive buildup occurs against a backdrop of sustained Ukrainian deep-strike campaigns using autonomous drones, highlighting Russia's adaptation to asymmetric threats rather than broad offensive war preparations. In parallel, European critical infrastructure faces documented gaps: an IISS report details Russian-linked drone incursions over NATO sites, airports, and nuclear facilities across a dozen countries from 2024-2026, exposing limitations in detection and response systems optimized for conventional threats. Euractiv interviews with drone experts underscore Europe's lack of national-level coordination for protecting airports, power stations, and energy sites, with incidents in Denmark, Lithuania, and elsewhere. US concerns echo this, with FBI Deputy Director warnings of imminent battlefield-style drone risks domestically. These developments amplify perceptions of eroding security, potentially fueling political debates on defense budgets, counter-drone investments, and support for Ukraine amid hybrid warfare risks.
