Russia-linked oil tanker drags anchor, damaging undersea cables between Finland and Estonia.

On 25 December 2024 the oil tanker Eagle S (flagged in the Cook Islands but identified as part of Russia’s “shadow fleet”) is accused by Finnish authorities of dragging its anchor across the seabed for about 90–100 km, thereby damaging the Estlink-2 power cable and several telecom cables linking Finland and Estonia. Finnish prosecutors subsequently filed charges of aggravated criminal mischief and aggravated interference with communications against the ship’s captain and two senior officers. The incident occurred in the Gulf of Finland — a strategic corridor between Russia, Finland and the Baltic states — highlighting Finland’s vulnerability in the seabed domain. Although services remained operational via alternative links, the damage triggered alarm over the resilience of Nordic undersea infrastructure. The geographic dynamic underscores how maritime and subsea domains can be targeted to exert pressure and test responses without overt aerial or land attack. The investigation remains ongoing, and the vessel’s status and crew accountability continue to be contested by Russia and related entities. The episode led Finland and its allies to accelerate monitoring of undersea cables, dark-ship activity, and shadow‐fleet behaviour in the Baltic region.
