SIPRI Spotlight: 

Maritime hybrid threats in the Baltic Sea

As part of the SIPRI event with the French Embassy on maritime hybrid threats in the Baltic Sea, SIPRI interviewed Dr Nicolas Mazzucchi, Head of Naval Strategy and Wargaming at the French Navy Centre for Strategic Studies (CESM).

In the interview, Dr Mazzucchi reflects on the growing security risks beneath the Baltic Sea, highlighting the vulnerability of critical underwater infrastructure and the strategic implications of seabed warfare. He discusses the need for stronger civilian–military cooperation, enhanced intelligence-sharing and technological innovation, and explains why collaboration between NATO and the EU offers grounds for cautious optimism in securing Europe’s ‘green waters’.
