Russia Sends Fighter Jet to Guard ‘Shadow Fleet’ Vessel

In a significant escalation, Russia deployed a fighter jet to protect a vessel linked to its “shadow fleet,” marking a first for Moscow in such operations. On May 13, 2025, Estonian authorities attempted to inspect the unflagged tanker Jaguar, suspected of evading sanctions by transporting Russian oil. In response, a Russian Su-35 fighter jet entered Estonian airspace and escorted the vessel out of Estonian waters. This bold move has drawn international attention, highlighting Russia’s active role in sanction-busting activities and its willingness to protect assets tied to its economic interests.

The “shadow fleet” consists of hundreds of aging, poorly maintained vessels operating under flags of convenience to evade Western sanctions. These ships are believed to transport up to 85% of Russia’s oil exports, significantly contributing to the country’s national budget. Despite European Union sanctions targeting many of these vessels, legal challenges and enforcement difficulties continue to complicate efforts to stop the operation of the shadow fleet. The EU is preparing to blacklist more vessels, but the complex legal landscape and Russia’s increasing use of military assets to protect these ships raise concerns.

Estonia has pledged to continue monitoring and inspecting these vessels despite the confrontation. The incident underscores the growing tensions in the Baltic Sea, where NATO allies face escalating challenges in countering Russia’s maritime strategies. As the situation develops, further diplomatic and military responses are expected, signaling heightened geopolitical instability in the region.
