NATO faces challenges in countering Russia's shadow fleet in the Baltic Sea (defence24.com)

• Shadow fleet generates $87-100B annually for Russia's war.
• Militarization includes GRU- and Wagner-linked crews.
• Sweden seized tankers; UK boarded a tanker in the English Channel.
• Caffa case provides legal template for confiscations.
• NATO lacks coordinated strategy; NB8+ states lead.

"Russia's shadow fleet, an opaque network of tankers transporting sanctioned oil, generates $87-100 billion annually for Moscow's war effort and poses environmental and military threats in the Baltic Sea. NATO allies show uneven responses: Sweden seizes vessels, Estonia is cautious, the UK boarded a tanker. Militarization of the fleet includes crews with military backgrounds. Legal and political obstacles hinder coordinated action, but recent cases like Sweden's Caffa detention offer templates."
