Undersea Cables: A New Strategic Battleground for National Security and Communication

The Critical Role of Undersea Cables

• 💡 Nearly 1.5 million kilometers of submarine cables form the backbone of global communication and data flow, essential for national security and economic stability.
• ⚠️ Despite their importance, these cables are highly vulnerable, with an increase in disruptions noted in recent years.

Disruptions and Potential Sabotage

• ⚡ While many cable outages are accidental, attributed to human or industrial activities, a minor number are suspected to be linked to sabotage by state-sponsored actors.
• 🇷🇺🇨🇳 Russia and China have been identified as potential perpetrators in regions like northern Europe and Taiwan.
• 🕵️ Industrial companies like Alcatel Submarine Networks focus on repair, leaving investigations into hostile intent to intelligence and defense agencies.

Protecting Europe's Digital Infrastructure

• 🇪🇺 Protecting underwater infrastructure has become a top priority for NATO and the EU, particularly in the Baltic and North Seas, with warnings of Russian-backed actors.
• 🚢 Incidents include damage to telecom cables connecting Finland and Estonia, with investigations ongoing into potential aggravated disruption and sabotage.
• ⚓ While some incidents are ruled accidental, the proliferation of disruptions since the Ukraine war suggests a potential covert campaign of hybrid warfare.

Public vs. Private Responsibility and Resilience

• 🏛️ There's growing awareness and action from the public sector, especially the EU, with an action plan for cable security focusing on prevention, detection, response, and deterrence.
• 🌐 Telecom operators build in redundancy and alternate routing options to minimize traffic impact from cable cuts, though power cables may be more vulnerable.
• 🤝 The industry subscribes to these plans and offers expertise and assets, like maintenance vessels, to improve cable resilience.

Global Risks and Future Trends

• 🌍 Undersea cable security is a global issue, with geopolitical powers investing in the seabed environment to exert influence.
• 🚀 Artificial intelligence is expected to drive significant growth in data traffic, necessitating more connectivity between data centers, which are locating in areas with cheap and abundant energy.
• 🗺️ Cable routes are evolving beyond traditional paths (US-Europe, US-Asia) to new geographies where data centers can be economically installed.
• 🌊 The industry is also leveraging its presence on the seabed to deploy devices for measuring environmental parameters related to climate change and to serve as an early warning system for tsunamis by detecting seabed earthquakes.
