Summary
Surveillance photos from mid-May show Russia fortifying the Gazprom-owned Marshal Vasilevskiy with sandbagged firing positions and Kord 12.7-millimeter heavy machine guns on both sides of the bridge.
Passenger lists from August 2025 identified 50 non-crew travelers on the tanker, and reporters linked 22 of them to Russian military structures, including the FSB; five used military identification in June.
The vessel is a critical energy link to Kaliningrad, making at least four runs since last August from Bolshoy Bor past Estonia, Latvia and Lithuania while carrying LNG and regasification capability.
European intelligence and defense officials said the weapons likely aim to deter boarding or seizure and signal pressure on NATO, while some also saw a secondary role in guarding against possible Ukrainian attacks.
Estonian officials warned the arming of a civilian tanker raises the risk of confrontation in Baltic waters, with the navy saying it would be obliged to defend any ship attacked in Estonian waters.

Overview
In March 2026, the Russian gas carrier Arctic Metagaz was attacked by a maritime drone in the Mediterranean Sea, causing a fire, forcing the crew to evacuate, and leaving the vessel adrift before it was towed to Libya. This incident highlighted the vulnerability of commercial vessels to drone attacks and signaled a growing threat to critical energy infrastructure at sea. In response, Russia has begun arming its LNG carrier Marshal Vasilevskiy, marking a new precedent where commercial ships are equipped with military defenses. This shift blurs the line between civilian and military maritime operations, raising the risk of escalation in contested regions.
