Multiple undersea infrastructure attacks in the Baltic Sea occurred from 2022 to 2025, targeting pipelines and cables connecting Nordic and Baltic countries with Russia.
The Wilson Center provides a detailed timeline and mapping of several undersea infrastructure attacks in the Baltic Sea region from September 2022 through early 2025. The notable incidents include explosions damaging Nord Stream pipelines and other critical undersea energy infrastructure that runs from Russia to Germany via the Baltic Sea, involving locations near Denmark, Sweden, and Estonia. These attacks disrupted energy transit routes and raised significant regional security concerns due to the heightened vulnerability of these critical maritime assets. The timeline highlights repeated sabotage attempts, including twin incidents on November 18, 2024, and further damage on December 25, 2024. By early 2025, continued threats to undersea cables and pipelines have stressed the need for enhanced protection of maritime infrastructure in this geopolitically sensitive area.
Confidence: High
The event documents multiple undersea sabotage attacks in the Baltic Sea region explicitly linked to pipelines and cables tied to Russian energy exports. The mapping and timeline clearly indicate hostile underwater attacks consistent with prior Russian hybrid warfare tactics in the region. The actor is implicitly Russia as the primary aggressor targeting Baltic Sea infrastructure.
