Ukraine Intensifies Drone Attacks on Russian Oil Infrastructure, Crippling Exports
Ukrainian drone strikes targeting key Russian oil infrastructure have escalated, causing significant disruption to exports and raising concerns about global fuel markets. The latest attacks, occurring on the night of March 25, focused on the Ust-Luga port in the Leningrad region, sparking a fire and temporarily halting operations.
According to Alexander Drozdenko, the governor of the Leningrad region, firefighters are working to contain the blaze at the port, and preliminary reports indicate no injuries. AP News reports that 56 drones were intercepted over the region during the attack.
Ust-Luga: A Critical Russian Energy Hub
Ust-Luga is Russia’s largest port on the Baltic Sea and the second largest in the country, handling substantial volumes of oil, diesel, fuel oil, aviation fuel, and gas oil. Newsweek data indicates that the port exported approximately 700,000 barrels of oil per day in 2025, with a total petroleum product export volume of 32.8 million tons.
Escalation Following Primorsk Attack
The attack on Ust-Luga follows a similar drone strike two days prior on Primorsk, Russia’s largest oil port on the Baltic Sea. Both ports experienced temporary suspensions of oil supplies to foreign markets, though the initial attack on Ust-Luga was not officially reported at the time. The Moscow Times reports that industry sources indicated Ust-Luga was as well shut down following the Primorsk attack, though this was not officially confirmed.
Impact on Global Energy Markets
These strikes on Russian oil infrastructure are complicating Moscow’s ability to capitalize on the global energy crisis, particularly in light of ongoing conflicts in the Middle East. Reuters sources suggest that total oil exports from Baltic and Black Sea ports in March could fall to 1.7 million barrels per day, the lowest level since the start of the war. Disruption to Russian exports is likely to further unsettle global fuel markets and worsen concerns over oil and gas shortages.
Widespread Drone Assault Across Russia
The Russian Ministry of Defense reported intercepting and destroying 389 Ukrainian drones overnight across multiple regions, including Crimea. AP News details that the attack on the Leningrad region was one of the largest during the war, with 56 drones downed.
Damage to Military Icebreaker and Historical Building in Vyborg
The attacks extended beyond Ust-Luga, with reports of damage to a military icebreaker at the Vyborg Shipyard. Monitoring channels reported a strike on a border patrol ship of project 23550, causing it to lean to one side. The icebreaker, known as “Dzerzhinsky,” is under construction for the FSB border service and is valued at approximately 25 billion rubles. A building of cultural heritage in Vyborg, known as the “Agricola” building, sustained fire damage.
Governor Drozdenko confirmed that the roof of a residential building in Vyborg was also damaged, but no injuries were reported.
