Protecting Digital Infrastructure and Maritime Interests: India’s Sovereign Imperative

Protecting Digital Infrastructure and Maritime Interests: India’s Sovereign Imperative

India’s undersea cable infrastructure is a glaring vulnerability amidst global maritime competition and an expanding digital economy. Despite facilitating over $10 trillion in daily financial transactions globally, submarine cables remain underappreciated as strategic assets in India. A country aspiring to redesign maritime geopolitics cannot afford delays, dependence, or neglect in safeguarding its digital lifelines.

The Institutional Landscape: A Crisis of Underpreparedness

The Information Technology Act, 2000, governs cybersecurity in India, yet does not explicitly recognize submarine cables as critical infrastructure. Government oversight is fragmented, with agencies such as the Ministry of Communications and NCIIPC sharing jurisdiction but rarely integrating defense, telecom, and maritime strategies. For example, there are no binding regulations for cable operations under India’s Exclusive Economic Zone (EEZ), unlike U.S. policies requiring strict monitoring.

Furthermore, gaps abound in physical capability. India lacks a domestically flagged cable repair fleet, relying heavily on foreign vessels, which face delays of up to 12 days during disruptions. The absence of advanced underwater sensors and a cohesive surveillance mechanism compounds these risks. In stark contrast, countries like China are deploying state-funded vessels and monitoring systems under its Digital Silk Road initiative, integrating infrastructure expansion with geopolitical strategy.

India operates only 17 international subsea cables through 14 Cable Landing Stations (CLSs), hosting a mere 1% of global operational sites. This puts undue pressure on hubs like Mumbai and Chennai. With current expansion plans aiming only for a four-fold increase in transmission capacity by 2025, India remains leagues behind the Asia-Pacific market’s potential CAGR of 5.6% and its 38.6% share.

Concrete Evidence: Where India Stumbles

Dependency and delays: India suffers 8–9 cable cuts annually, each costing ₹15–20 crore in repairs. Without domestically flagged cable vessels, repair time lags behind countries like China, which operates six repair vessels strategically stationed to minimize downtime.

Chokepoints and vulnerabilities: Strategic maritime zones like the Malacca Strait and Luzon Strait are potential targets for sabotage and espionage. This is exacerbated by rising geopolitical tensions and the absence of underwater surveillance infrastructure. Neither the Navy nor the Coast Guard has integrated submarine cable security into their operational protocols.

Geopolitical stressors: As highlighted by the National Security Council Secretariat (NSCS), cables in India’s EEZ face increasing risks of tampering and interception. The United Nations Convention on the Law of the Sea (UNCLOS) provides only weak mandates, relying on flag states for enforcement—an inherent loophole exploited by state actors like Russia and China.

Private sector concentration: Private operators dominate India's cable landscape, creating uneven growth and exposing sensitive data routes to commercial priorities rather than strategic imperatives.

The Counter-Narrative: Pragmatism Amid Expansionism?

One argument against emphasizing submarine cable security is rooted in cost-efficacy. Critics argue India’s geopolitical ambitions may inflate defense spending disproportionately to economic benefits. Investing in cable repair vessels, advanced sensors, and autonomous drones requires billions in public funds—not a trivial allocation for a developing nation with competing priorities like health and education.

Furthermore, the private sector has already begun expanding capacity with new systems expected to quadruple data transmission by 2025. This suggests that private investment complements existing government ambitions, minimizing the need for duplication. However, this “market knows best” narrative barely addresses India's dependency on foreign vessels and the absence of contingency frameworks during sabotage scenarios.

International Perspective: China's Assertive Model

China’s Digital Silk Road offers a stark contrast. Its state-funded strategy integrates maritime and cyber capabilities, deploying surveillance vessels, underwater sensors, and redundant cable corridors. One example is the Europe–Middle East–Asia cable route, established under Belt and Road Initiative (BRI) projects to cement geopolitical influence alongside economic value. Such foresight makes China less exposed to foreign dependencies and chokepoints—a model India must adapt, albeit selectively.

What India calls maritime vigilance, China would term strategic sovereignty. While India debates infrastructure upgrades piecemeal, China’s comprehensive approach securing both physical and cyber dimensions leaves no room for strategic ambiguity.

Assessment: What Must Change?

The protection of submarine cables demands a National Submarine Cable Security Framework. A policy overhaul is essential, led by the NSCS, integrating defense, cyber, and telecom agencies. Designating cables as Critical Information Infrastructure under the NCIIPC should be the first regulatory step. Additionally, the TRAI recommendation for a 10x expansion in infrastructure must address regional imbalances, prioritizing vulnerable chokepoints.

Building strategic redundancies—new cable routes, tamper-proof designs, and advanced encryption—should be coupled with international cooperation. Joint patrols under QUAD’s umbrella could deter tampering while sharing technological expertise. However, the most urgent gaps remain domestic: manufacture cable repair fleets, train cyber-maritime units, and accelerate underwater monitoring systems through the iDEX initiative.
