As the war in Ukraine enters its fourth year, concerns are mounting over Russia’s escalating efforts to destabilize Europe through a multifaceted “hybrid” warfare strategy. This includes not only conventional military actions but also covert operations targeting critical infrastructure and economic pressure tactics, according to recent assessments from French naval intelligence. The increasing frequency of Russian naval activity near European coasts, coupled with reports of sabotage and a vast network of vessels circumventing sanctions, is raising alarm among European security officials.
French Chief of Naval Staff Nicolas Vaujour detailed the scope of the threat on Monday, describing a pattern of aggressive behavior and deliberate attempts to undermine European security. Vaujour highlighted the presence of a “ghost fleet” – an estimated 1,000 vessels actively working to bypass European sanctions on Russian oil exports. This fleet, alongside incidents of underwater cable sabotage and drone incursions, represents a significant escalation in Russia’s hybrid warfare tactics.
The French naval chief revealed that Russian vessels, including submarines, are regularly encountered in European waters. “Approximately one Russian ship or submarine passes along our coasts each week,” Vaujour stated in an interview with France 2, as reported by Le Figaro. In the Baltic Sea, these encounters have been particularly aggressive, with Russian vessels engaging in maneuvers deemed unacceptable by French naval units. In response, French forces are actively monitoring and shadowing these vessels, demonstrating a clear indicate of force.
“Ghost Fleet” Tactics and Sanctions Evasion
The “ghost fleet” is central to Russia’s strategy of circumventing international sanctions imposed in response to the invasion of Ukraine. These vessels employ tactics such as sailing without visible flags and utilizing complex ownership structures to obscure their origins and destinations. One such vessel, the Boracay (also known as the Pushpa), a member of this fleet, was intercepted off the French coast in September 2025 although carrying Russian oil destined for India. French prosecutors have since requested a one-year prison sentence and a €150,000 fine for the vessel’s commander, the maximum penalty under French law.
Beyond sanctions evasion, Russia is also accused of engaging in more subtle forms of destabilization. Vaujour cited instances of drone overflights in countries like Poland and deliberate damage to underwater communication cables. He described these actions as “typically Russian, unclaimed, and aimed at destabilizing us,” suggesting a deliberate strategy of creating uncertainty and undermining European infrastructure. The damage to underwater cables, sometimes attributed to innocent accidents like anchors dragging along the seabed for up to 100km, is nonetheless considered a serious security concern.
Broader Geopolitical Context and European Response
These actions occur against the backdrop of a prolonged conflict in Ukraine, where Russia’s military objectives have faced significant setbacks. While Moscow continues to assert its aims in Ukraine, its broader strategy appears to encompass a wider effort to challenge the existing European security order. The increased naval activity and hybrid warfare tactics are seen as attempts to exert pressure on European nations and divert resources away from supporting Ukraine.
France, along with other European nations, is responding to these threats through increased naval patrols, enhanced intelligence gathering, and closer cooperation with international partners. Vaujour emphasized the importance of a coordinated approach, stating that France is capable of responding with both military and judicial action. “We continue with all administrations, which is our strength today – being able to go from military action to judicial action,” he said.
The situation underscores the growing complexity of modern warfare, where traditional military conflicts are increasingly intertwined with cyberattacks, economic coercion, and covert operations. European nations are now grappling with the challenge of defending against these multifaceted threats while simultaneously supporting Ukraine and maintaining internal stability.
Looking ahead, continued vigilance and international cooperation will be crucial in countering Russia’s hybrid warfare tactics. The focus will likely remain on tracking and disrupting the “ghost fleet,” protecting critical infrastructure, and strengthening European resilience against future attacks. Further investigations into incidents of sabotage and drone incursions are expected to shed more light on the extent of Russia’s destabilizing activities.
