Scholars emphasize Public-Private Partnerships (PPPs) to expedite technology transfer, akin to models employed by France and Japan in developing high-tech cable-laying ships.
Maritime Security and Domain Awareness
1. Cable-Cutting Threat
-
- China’s unveiling of a compact deep-sea cable-cutter underscores the non-traditional security threats lurking in international waters. This capability, which can disrupt heavily fortified communication lines, represents a strategic challenge not just for India but for other global players relying on submarine cables.
-
- Robust Underwater Domain Awareness (UDA) is critical to pre-empt such acts. UDA combines acoustic surveillance, satellite-based monitoring, and real-time data analytics to detect anomalies around critical subsea infrastructure.
2. Submarine Operations
-
- Dual-Use Nature: Manned and unmanned submersibles developed for oceanographic research can also be repurposed for underwater offensives or surveillance. This necessitates comprehensive regulations ensuring that the civilian and military dimensions of submersible technology are governed responsibly.

Maritime experts stress the importance of synergy between the Indian Navy, Coast Guard, and research bodies to bolster blue-water capabilities.
THE CHALLENGES:
TECHNOLOGICAL COMPLEXITIES
1. Communication Underwater
-
- Variable Sound Propagation: Underwater communication relies on sound waves, whose effectiveness can fluctuate due to temperature, salinity, and pressure gradients. This variability necessitates cutting-edge research into Very Low Frequency (VLF) and Extremely Low Frequency (ELF) acoustic technologies.
- High R&D Costs: Developing robust underwater communication systems is capital-intensive, often requiring advanced labs and long-term experimentation. National Maritime Foundation (NMF) highlight that even minor innovations in acoustic sensor arrays or subsea data links can cost millions of dollars.
- US Undersea Warfare Research: The United States Naval Research Laboratory (NRL) has spent decades refining sonar and communication buoys. The complexity and funding required serve as a benchmark for emerging economies, which must balance security imperatives with resource constraints.
2. Extreme Pressure
-
- Exponential Increase in Pressure: At roughly 3,700 metres—the average depth of India’s Exclusive Economic Zone (EEZ)—the water pressure exceeds 380 atmospheres. The OceanGate Titan submersible tragedy underscored how even minor material or structural flaws can lead to catastrophic implosion at depth.
- Specialized Materials & Hull Construction: Conventional steel or aluminium hulls often fail under extreme pressure. Advanced materials like titanium alloys or carbon-fiber composites require precision engineering. The National Institute of Ocean Technology (NIOT) in India collaborates with global material-science firms to develop pressure-resistant submersibles, but the supply chain for high-grade alloys remains narrow.
- Regulatory Perspective: Internationally, under UNCLOS guidelines, flag states are responsible for the safety of submersibles in their waters. However, no uniform global standards exist for deep-sea vessel certification, leading to regulatory gaps.
RESOURCE-INTENSIVE DEVELOPMENT
1. High Capital Costs
-
- Building Submersibles and Support Ships: Each deep-sea exploration vehicle can cost anywhere between USD 50–200 million, excluding the specialized support vessels and research platforms. For instance, Norway’s “REV Ocean” research vessel has an estimated build cost exceeding USD 350 million.
- Sustained Funding for Frontier Technologies: There is a need for diversified funding sources—government grants, public-private partnerships (PPPs), and international collaborations. However, constraints often arise due to competing national priorities (healthcare, infrastructure, etc.).
- India’s Deep Ocean Mission: With an outlay of around INR 4,000 crore, the Mission aims to foster indigenous technology in underwater mining and submersibles. However, continuous funding, parallel skill development, and global technology partnerships are crucial for mission success.
2. Skilled Manpower
-
- Multidisciplinary Expertise: Deep-sea exploration demands specialists in marine biology, geology, hydrodynamics, robotics, and advanced materials. While India has premier institutions like the Indian Institute of Technology (IIT) and Cochin University of Science and Technology (CUSAT), the pool of experts with practical undersea experience remains limited.
- Training and Retention: A recurring challenge is the “brain drain” of trained professionals to advanced maritime nations. Government-appointed committees (e.g., the Rajya Sabha Committee on Science & Technology) have repeatedly recommended bolstering oceanographic research institutes with better salaries and research grants.
- Global Collaboration: Nations like Japan and South Korea have robust science-technology corridors that link universities, research labs, and industry for skill upgradation. Replicating similar models in India and other emerging economies can enhance local talent pipelines and reduce overreliance on external expertise.
POLICY AND GOVERNANCE GAPS
-
- Fragmented Oversight: Multiple agencies—ranging from environmental regulators to maritime security bodies—stake claim over deep-sea matters.
- Environmental Safeguards: Deep-sea mining and submersible missions can disrupt fragile benthic ecosystems. Environmental Impact Assessments (EIAs) often lack long-term studies on deep-sea biodiversity. Conservationists, referencing reports by the International Union for Conservation of Nature (IUCN), call for stringent protocols before large-scale exploitation.
- Legal and Constitutional Dimensions: In India, Article 297 of the Constitution vests “all lands, minerals, and other things of value underlying the ocean within the territorial waters” in the Union Government. However, clarity on deep-sea (beyond territorial waters) resources remains guided more by UNCLOS than domestic statutes, creating intricate legal interpretations and potential jurisdictional disputes.
THE WAY FORWARD:
1. INSTITUTIONAL OVERHAUL AND GOVERNANCE REFORMS
-
- Ministry of Ocean Development: Elevating the Department of Ocean Development to a full-fledged ministry with a Cabinet-rank Minister will harmonize policy, budget allocation, and regulatory frameworks. This idea finds support in the recommendations of several Parliamentary Standing Committees that stress a single-window authority for maritime affairs.
- Ten-Year Mission Roadmap: A clear timeline with mission-mode objectives (e.g., “Deep Ocean Mission: 2025–2035”) can expedite decision-making and accountability. Drawing inspiration from India’s Chandrayaan project, the approach should include real-time performance metrics and outcome-based funding.
- Unified Regulatory Framework: Since Article 297 of the Indian Constitution vests resources in the Union, a consolidated legal architecture can reduce bureaucratic overlaps. The policy should be aligned with UNCLOS provisions for EEZ management, ensuring India’s rights and obligations are firmly integrated into domestic legislation.
2. STRENGTHENING RESEARCH & DEVELOPMENT ECOSYSTEM
-
- Centres of Excellence in Marine Science: Establish specialized institutes—modeled on the lines of the Indian Institutes of Technology (IITs)—focusing exclusively on marine engineering, oceanography, and underwater robotics. Such institutes could collaborate with leading global research bodies like Woods Hole Oceanographic Institution (US) or IFREMER (France).
- Innovation Grants & Blue Bonds: Introduce “Blue Bonds” or Sustainability-Linked Bonds to channel investments into critical domains such as low-frequency underwater communication, pressure-resistant materials, and submersible design. Provide competitive grants for start-ups, universities, and public-private consortia to foster indigenous technologies.
3. Building a Skilled Manpower Base
-
- Marine Tech Parks and Fellowship Programs: Setting up Marine Tech Parks in coastal hubs (e.g., Kochi, Visakhapatnam) can create an ecosystem of scientists, engineers, and private innovators. In parallel, a Deep Ocean Fellowship program—integrating engineering, marine biology, law, and policy students—would cultivate multidisciplinary expertise.
- National Skill Development Mission: Integrate deep-sea modules under the National Skill Development Corporation (NSDC) to offer certified training for submersible pilots, ROV technicians, and maritime environmental officers.
- Retention and Reverse Brain Drain: Attractive remuneration packages, research grants, and global exposure—backed by a strong policy impetus—could help retain skilled professionals.
4. Robust Strategic Infrastructure and Security
-
- Underwater Domain Awareness (UDA): Develop integrated sensor networks, acoustic arrays, and satellite overlays for comprehensive submarine detection and cable protection. The National Maritime Foundation suggests layering acoustic buoys with AI-driven analytics for real-time threat identification.
- Hardening Critical Infrastructure: Enforce stricter cable-laying and sub-sea pipeline construction guidelines. Drawing from the US and UK’s models, ensure redundant cable routes and adopt high-grade protective sheathing to counter sabotage or accidental damages.
- Dual-Use Technology Protocols: Formulate clear regulatory standards for dual-use equipment—submersibles built for resource exploration but adaptable for military reconnaissance. The UN Institute for Disarmament Research (UNIDIR) recommends robust confidence-building measures (CBMs) to prevent escalatory use of underwater assets.
5. Ensuring Environmental Sustainability and Climate Resilience
-
- Stringent Environmental Impact Assessments (EIAs): Mandate comprehensive EIAs for deep-sea mining, referencing international best practices from ISA regulations. Experts from IUCN warn against irreversible harm to unique benthic species if extraction is unregulated.
- Marine Protected Areas (MPAs): Declare no-mining zones in ecologically sensitive regions within the EEZ to preserve biodiversity, aligned with India’s obligations under the Convention on Biological Diversity (CBD).
- Climate Data Integration: The Deep Ocean Mission should synergize with climate research bodies to feed oceanographic data into IMD (India Meteorological Department) and other global climate models. Real-time deep-sea temperature and salinity data can enhance disaster preparedness for cyclones and tsunamis.
THE CONCLUSION:
Harnessing the deep sea is not merely a technological pursuit but a moral imperative to equitably and sustainably unlock Earth’s final frontier—India must lead with innovation, foresight, and responsibility, balancing economic ambition with ecological stewardship. By integrating mission-driven governance, indigenous R&D, and strategic ocean diplomacy, India can transform its maritime potential into a pillar of national resilience and global leadership in the emerging Blue Economy era.
