Russia's shadow fleet, comprising aged vessels, is increasingly linked to hybrid warfare tactics, including sabotage of undersea cables and espionage. The fleet is estimated to consist of 600 to 3,200 vessels, transporting up to 80% of Russia's seaborne crude oil exports. Recent incidents, such as the seizure of the Fitburg cargo vessel by Finnish authorities, highlight the threat posed to critical infrastructure in the Baltic Sea. The fleet's operations are characterized by a lack of transparency in ownership and safety standards, making it difficult for European nations to respond effectively. The European Union has recently added 632 tankers to its sanctions list, yet the shadow fleet continues to thrive due to legal and operational gaps. As the situation evolves, the threat to undersea cables and maritime security remains significant.

Key Points: • Russia's shadow fleet is linked to hybrid warfare, including sabotage and espionage. • The fleet transports up to 80% of Russia's seaborne crude oil exports, generating significant revenue. • Recent incidents, like the Fitburg seizure, underscore the risks to critical infrastructure in Europe.
