Surveillance photographs have revealed that Russia has mounted heavy machine guns and fortified positions on a civilian liquefied natural gas (LNG) tanker, the Marshal Vasilevskiy, operating in the Baltic Sea. The Organized Crime and Corruption Reporting Project (OCCRP) reported this development, citing images taken in May 2026 by Estonian border guards. The vessel is crucial for supplying the Russian exclave of Kaliningrad, located between NATO members Lithuania and Poland.
The images show 12.7-millimeter caliber Kord heavy machine guns positioned behind sandbag fortifications on both sides of the tanker's bridge. This marks the first documented instance of Russia arming a civilian vessel with such heavy weaponry, according to experts. The Marshal Vasilevskiy, owned by Russian state-run energy giant Gazprom, makes regular runs from Bolshoy Bor on the Gulf of Finland to Kaliningrad.
Beyond the armaments, reporters also identified approximately two dozen "passengers" aboard the civilian ship with backgrounds in the Russian military, including the FSB intelligence service. The Dossier Center, a partner in the investigation, found that some of these individuals presented military identification when boarding. This suggests a deliberate deployment of trained personnel alongside the weaponry.
Defense experts and intelligence officials have offered various rationales for Russia's actions. Some suggest the weapons are intended to deter potential Ukrainian drone attacks or to exert pressure on NATO countries in the Baltic Sea. Others believe it sends a message to Western authorities regarding the "shadow fleet" of tankers, making any boarding attempts significantly riskier.
Commodore Ivo Värk, commander of Estonia’s navy, highlighted that since the tanker supplies natural gas vital for both Kaliningrad residents and Russian armed forces stationed there, it could be regarded as a military target. Jens Wenzel Kristoffersen, a Danish naval commander, warned that if NATO forces were to approach the ship, they might face warning shots or direct fire, emphasizing the dangerous implications of this militarization. The Marshal Vasilevskiy is not part of the "shadow fleet" but serves as a strategic backup supply route for Kaliningrad.
