NATO and EU members have increased coordination to secure critical undersea infrastructure in the Baltic, Barents, and Arctic regions against potential Russian sabotage.
Key facts
- •NATO and the EU have increased coordination to protect undersea infrastructure through joint planning and new security initiatives.
- •The U.K.–Norway Lunna House Agreement and NATO’s Baltic Sentry are among the measures implemented to improve regional defense.
- •Poland and Sweden launched the Baltic Sea Pact in June to deepen bilateral security cooperation.
- •The European Union introduced resilience measures in May 2025 to complement existing NATO efforts.

Since 2025, NATO and European Union members have implemented new measures to safeguard critical undersea infrastructure from potential Russian sabotage. Initiatives include closer planning, joint security measures, and specific regional agreements aimed at enhancing deterrence in the Baltic, Barents, and Arctic regions.
New Security Initiatives and Agreements
Efforts to improve maritime security include the U.K.–Norway Lunna House Agreement and NATO’s Baltic Sentry initiative. Additionally, NATO allies and the European Union signed a Memorandum of Understanding focused on infrastructure protection. In May 2025, the EU introduced further resilience measures, while Poland and Sweden established the Baltic Sea Pact in June to strengthen bilateral defense cooperation.
Ongoing Challenges and Strategic Needs
Despite these developments, the geographic scale of the Baltic, Barents, and Arctic regions combined with Russia's persistent presence makes eliminating the threat entirely difficult. Nurlan Aliyev notes that Russian research vessels often function as platforms for deploying robotic systems, necessitating a greater focus on these capabilities. Continued U.S. involvement in Arctic operations remains a strategic priority.
