Intelligence reports indicate that shadow tankers increasingly launch and operate drones targeting European countries. Ukrainian authorities say Russian-backed initiatives are behind these operations. Using shadow tankers as mobile drone bases allows attackers to carry out strikes from international waters, making it difficult for European defenses to track or intercept the drones before they reach their targets.
Shadow Tankers Behind Drone Attacks
The issue comes amid growing security concerns in Europe, where multiple drone incursions have already been reported near airports and military bases. Officials note that shadow tankers are not only transporting energy but also serving as strategic platforms for drone operations, highlighting a significant escalation in unconventional maritime threats. These vessels can act as floating launch points, enabling drones to cover large distances and reach strategic locations in Europe without relying on land-based infrastructure.
Experts point out that the dual-use nature of shadow tankers—commercial transport and military support—presents both economic and security challenges. Restricting their operations in critical seas such as the Baltic Sea has become a pressing concern. Authorities stress that without proper regulation and monitoring, shadow tankers could continue to pose serious risks to civilian and military infrastructure in the region.

Europe’s Response to Shadow Tankers and Sanctions Measures
In response to the growing threat posed by shadow tankers, the European Union is preparing a new sanctions package targeting the energy trade and infrastructure connected to these vessels. The plan, expected to be announced this week, will reportedly include measures to redlist over 100 ships to curb the movement of shadow tankers and other vessels suspected of supporting drone operations.
Since the conflict began in February 2022, the EU, US, and UK have already imposed sanctions on more than 540 tankers linked to Russian oil trading. These authorities targeted ship managers, companies operating under specific flag states, and Russian oil companies. The latest intelligence showing shadow tankers used for drone launches increases the urgency to expand these sanctions, as officials aim to prevent vessels from being repurposed for military operations.

Countries across Europe have also taken domestic precautions. Denmark temporarily closed airports after drone incursions and imposed a civil ban on drone flights. Germany is investigating potential sabotage and espionage after drones appeared in Schleswig-Holstein, a state bordering Denmark. While neither country explicitly named Russia, officials suggest state actors likely carried out the operations, with Moscow indicated as the probable source. These steps show a growing understanding that shadow tankers serve not only as economic tools but also as instruments for military and strategic purposes.
European countries are increasingly coordinating to strengthen maritime surveillance, monitor tanker movements, and respond quickly to any potential drone threats launched from these vessels.
Recent Incidents and Security Concerns
The intelligence about shadow tanker operations follows a series of drone and missile attacks on Kyiv and other parts of Ukraine. One such assault lasted more than 12 hours and caused multiple casualties, including at least four fatalities. The attacks demonstrate how drones launched from unconventional platforms like shadow tankers can bypass traditional defense systems, highlighting a new level of maritime threat.
The European Union is also accelerating the halt of Russian LNG imports earlier than originally planned. This decision partly aims to limit the operational capability of shadow tankers involved in energy transport and potential drone operations. EU leaders plan to meet in Copenhagen this week to discuss strategies to strengthen European defense systems and enhance support for Ukraine.

Ukrainian intelligence reports that certain tankers operating in international waters can deploy drones without standard monitoring systems easily detecting them. This flexibility creates significant challenges for maritime security and protecting critical infrastructure across Europe. The upcoming EU sanctions package will target these vessels, along with associated ship managers, flag states, and companies that could potentially facilitate such operations.
Authorities stress that addressing the threat of shadow tankers involves not only regulating energy trade but also actively safeguarding European nations from emerging drone-based threats. The EU plans comprehensive measures to disrupt both the economic and military utility of these vessels.
