Ukrainian Drone Campaign Halts 40% of Russian Oil Export Capacity from Baltic Ports

Ukrainian drones struck Russian Baltic oil infrastructure for a third consecutive day, hitting the Ust-Luga port, Primorsk terminal, and the Kirishi (Kinef) oil refinery in Leningrad Oblast. Reuters called it the most severe oil supply disruption in modern Russian history, with at least 40% of Russia's oil export capacity knocked offline. The Ust-Luga strike alone damaged three oil tankers, five fuel storage tanks, three berths, and Novatek facilities. The strikes targeted facilities over 1,000 km from Ukrainian territory, a major extension of Kyiv's deep-strike capability that directly threatens the Kremlin's war financing pipeline.

Analysis
The 40% capacity disruption represents approximately 2 million bpd offline, compounding the Hormuz closure's 17.8 million bpd disruption. The 1,000+ km strike range demonstrates Ukrainian deep-strike capability that Russia's air defenses cannot reliably counter. Timing alongside the Iran war maximizes economic pressure on Moscow: Russia cannot reroute Baltic exports through a closed Hormuz.
