Seabed Security 2026 is the only international event dedicated exclusively to seabed defence, delivering first-hand insights and lessons learned from NATO’s largest Unmanned Maritime Systems exercise, REMPUS.

As activity on the seabed accelerates, protecting critical undersea infrastructure has become essential to economic stability, public safety, national security, and global resilience.

Bringing together military leaders, government, industry, and academia, the event fosters collaboration, shares real-world operational experience, and explores the strategies and technologies shaping subsea defence.

Across two focused days, the conference examines the evolving threat landscape for undersea infrastructure, the strategies being developed to secure seabed activity, and the advanced systems now being deployed for subsea defence.
