Seven students investigated and revealed the presence of Russian ‘drone motherships’ using open-source intelligence and technology, exposing a gap in European defense.
In an innovative open-source intelligence investigation, seven students analyzed maritime and communication data to uncover Russia’s use of ‘drone motherships’ — large civilian cargo ships repurposed to deploy and support unmanned underwater drones in the Baltic Sea. This operation was previously undetected by European intelligence. The team identified suspicious vessel movements, such as prolonged loitering and irregular patterns near underwater infrastructure in the Baltic region, particularly around the German port of Wismar and near Bornholm, Denmark. They highlighted the involvement of Rosatom, a Russian nuclear company, in developing drone technology capable of long-distance underwater operations. Their findings reveal a significant shortfall in European maritime surveillance and defense against sophisticated drone threats. This demonstrates the increased reliance on civilian vessels for covert military drone operations and underscores the need for enhanced intelligence cooperation and surveillance technology in Europe. The investigation was driven by the students’ collaboration with researchers and defense experts, illustrating the potential of academic and open-source contributions to filling intelligence gaps.
Confidence: High
The article explicitly details Russian hostile operations using drone motherships as platforms for underwater drones threatening European maritime infrastructure, constituting aggressive hybrid warfare tactics. There is no mention of defense preparations in response.

By correlating satellite, maritime traffic, and observational data, the students revealed that these vessels enable Russia’s unmanned underwater operations—the drones traveling over 200 kilometers to strike targets.
