Seabed Warfare in a New Era of Geotech Conflicts

Seabed Warfare in a New Era of Geotech Conflicts

Editorial Context: Geopolitics and the Militarization of the Ocean Floor

The ocean floor is rapidly transforming into a strategic battleground in global geopolitics. The interplay between technological advancements and geopolitical rivalries — a phenomenon termed "geotech conflicts" — has expanded the domain of warfare to uncharted depths of the seabed. Critical components of the global infrastructure, including undersea communication cables, energy pipelines, and surveillance networks, are increasingly vulnerable to sabotage and strategic control. This development raises serious implications for global security and energy supply chains, necessitating a reevaluation of international norms and technological preparedness.

Institutional Framework: Key Components of Seabed Warfare

Seabed warfare operates at the intersection of cutting-edge technology, strategic resources, and legal ambiguity. It involves activities on or below the ocean floor carried out for military, espionage, or economic domination purposes. The operational domain includes communication cables, oil and gas pipelines, underwater surveillance systems, and rare mineral resources.

• Key Technologies: Unmanned Underwater Vehicles (UUVs), Remotely Operated Vehicles (ROVs), AI-powered systems, seabed-deployed mines.
• Critical Assets Under Threat:
  • Over 95% of global internet traffic depends on undersea cables (World Bank data).
  • Seabed hosts ~30% of global oil and gas production (International Energy Agency).
  • Deep-sea rare earth deposits critical for electronic and renewable energy industries.
• Legal Framework: UNCLOS governs seabed resources and provides limited protection for undersea cables; inadequate enforcement mechanisms render it ineffective in the context of seabed militarization.

Key Issues and Challenges in Seabed Warfare

1. Vulnerability of Critical Infrastructure

• Undersea cables and energy pipelines, which power digital economies and supply chains, are susceptible to sabotage (e.g., Nord Stream explosions in 2023).
• Increased interdependence on undersea networks highlights the risk of cascading failures in global finance and communication systems.

2. Technological Militarization

• Deployment of autonomous underwater sensors and vehicles facilitates espionage and potentially acts of aggression.
• Concerns of "weaponizing the sea floor" through mining, drone deployment, and underwater mines, as observed in the South China Sea and Atlantic regions.

3. Strategic Competition Among Major Players

• China's "Great Underwater Wall" demonstrates extensive surveillance capabilities in the Indo-Pacific.
• Russia's Losharik submarine has been implicated in sabotaging undersea cables.
• Retaliatory risks — including counter-sabotage — have risen sharply with advanced offensive UUV systems.

4. Regulatory and Jurisdictional Ambiguity

• UNCLOS provides basic principles but lacks provisions to address militarization or protect critical infrastructure.
• Disputes over Exclusive Economic Zones (EEZs), as seen in the South China Sea and Arctic regions.

Global Efforts and India’s Position in Seabed Security

India is proactively expanding its operational and strategic capacity to safeguard undersea infrastructure within its maritime boundaries and beyond.

• Submarine Capabilities:
  • Acquisition of Scorpène-class submarines under Project 75, enhancing surveillance and defense capabilities.
  • Deployment of nuclear submarines like INS Arihant for strategic force projection.
• Seabed Infrastructure Protection:
  • Deep Ocean Mission initiated to secure India's claims over polymetallic nodules and other resources.
  • Use of AUVs for both coastal and deep-sea monitoring under NIOT.
• International Partnerships: Through the Quad, India enhances maritime domain awareness and safeguards undersea communication in the Indo-Pacific.

India	Scorpène-class submarines, INS Arihant	Deep Ocean Mission, Quad Framework	Indian Ocean

Critical Evaluation: Challenges to Seabed Governance

While UNCLOS remains the primary framework governing the ocean floor, it is increasingly ineffectual amidst rising militarization. The jurisdictional ambiguity around EEZs and dual-use technologies complicates enforcement. Furthermore, technological asymmetry between nations risks elevating geotech conflicts, as sabotage capabilities far exceed defensive technologies. Collective international regulations focusing on seabed-specific security — akin to arms control treaties — could be a long-term solution, but geopolitical rivalries pose significant barriers.

Structured Assessment

• (i) Policy Design Adequacy: Existing maritime laws under UNCLOS are ill-suited for addressing seabed militarization and critical infrastructure protection.
• (ii) Governance or Institutional Capacity: Uneven global capabilities, with advanced nations like the US, China, and Russia dominating seabed warfare technologies.
• (iii) Behavioural and Structural Factors: Technology-fueled tensions are exacerbating geopolitical rivalries, particularly in the Indo-Pacific and Arctic regions, where resource claims collide.
