Overview
- Estonia released images on Tuesday showing machine guns and sandbags mounted on the Marshal Vasilevskiy, with officials saying the photos were taken this spring inside Estonia’s area of responsibility.
- The Marshal Vasilevskiy is a Russian-flagged regasifying LNG carrier owned by Gazprom Flot that has moved fuel to Kaliningrad several times since early 2025 and can pump gas directly into pipelines.
- The ship and its owner are under Western sanctions from the UK, Canada, Australia and the EU, but sailing under the Russian flag makes seizure legally and politically fraught.
- Estonian and NATO officials have largely stopped detaining Russia-linked vessels that do not pose an immediate danger to avoid triggering a military escalation, reducing the chance of direct intervention.
- Analysts say arming a civilian vessel in the closely monitored Baltic Sea is unprecedented, could increase the risk of clashes at sea and will complicate enforcement of sanctions and local maritime safety.
