Baltic Sentry: NATO Guards Undersea Cables and Pipelines
Why in the news
The Dutch survey ship HNLMS Luymes, commanded by Belgium’s Erik Kockx, took part in a patrol that highlighted NATO’s Baltic Sentry operation. The mission guards seabed infrastructure at a time of rising regional tension.
Key facts
- Baltic Sentry started in January 2025 after ships suspected of Russian links damaged infrastructure by dragging anchors.
- At least 10 NATO ships are deployed, working with Baltic-rim member states, plus undersea drones and surveillance planes.
- Mainsail is an AI-powered application that studies shipping patterns and spots anomalies pointing to sabotage.
- A new NATO undersea infrastructure centre built a single combined map of the Baltic seabed.
- Response time was cut from 17 hours to 1 hour.
Equipment and platforms
| Platform | Role |
|---|---|
| HNLMS Luymes | Royal Dutch Navy hydrographic survey ship; normally inspects the seabed, here also a surveillance vessel |
| HNoMS Hinnoy | Fitted with sonar, submersible probes and maritime drones |
| Undersea drones and aircraft | Supplied by various NATO nations for monitoring |
Approach
- The aim is deterrence and prevention, not reacting after damage; visible surveillance is meant to discourage offenders, much like policing.
- Commander Kockx noted that vessels change their conduct once they realise they are watched.
- Humans stay essential: crews hold regular drills and stay ready to act on any threat flagged by AI.
- The operation involves NATO and non-NATO partners, from coast guards to commercial bodies, which makes authorities and responsibilities complex.
Significance
- The AI plus real-time surveillance model could be copied to protect strategic infrastructure in other maritime regions.
- Continued vigilance, technology and international cooperation are needed for success.
Exam angle
- Operation: Baltic Sentry; launched by NATO in January 2025.
- AI tool: Mainsail.
- Target: protecting subsea cables and pipelines in the Baltic Sea.
