Coastal Security and Maritime Threats

Introduction to Coastal Security and Maritime Geostrategy

The maritime domain forms the indispensable bedrock of India's economic, ecological, and strategic vitality. Bounded by the Indian Ocean to the south, the Arabian Sea to the west, and the Bay of Bengal to the east, India possesses a formidable maritime geography characterized by a sprawling coastline of approximately 7,516.6 kilometers (often cited as extending up to 11,098 kilometers when factoring in deep coastal indentations and extensive island security perimeters). This extensive shoreline encompasses nine states, four Union Territories, and a vast archipelago of 1,382 islands, many of which are uninhabited and remote. The country exercises jurisdiction over an Exclusive Economic Zone (EEZ) covering over 2 million square kilometers, a vast expanse that harbors critical marine resources, valuable hydrocarbons, and strategically vital coastal security architecture.

The imperative for a robust coastal security architecture is inextricably linked to India's profound economic dependence on the sea. Approximately 95% of the nation's trade by volume and 70% by value transits through oceanic routes. Furthermore, India imports nearly 85% of its crude oil requirements via the Indian Ocean Region (IOR), navigating critical and often volatile geopolitical chokepoints such as the Strait of Hormuz, the Bab-el-Mandeb Strait, and the Strait of Malacca. A secure maritime environment is not merely a defense prerequisite but an existential economic necessity. The disruption of Sea Lines of Communication (SLOCs) would impose severe fiscal and economic strains, underscoring why coastal and maritime security have transitioned from the periphery to the very core of India's national security matrix.

Historical Evolution of India's Coastal Security Architecture

Historically, India's defense posture was characterized by a pervasive "sea blindness," with strategic doctrines heavily skewed toward securing restive land borders with Pakistan and China. The initial recognition of coastal vulnerabilities emerged post the 1993 Mumbai bombings, where explosives were smuggled via the sea. Following the 1999 Kargil conflict, the Kargil Review Committee and the subsequent Group of Ministers (GoM) report in 2001 highlighted the necessity of specialized marine policing and unified border management. This led to the creation of the Department of Border Management under the Ministry of Home Affairs in 2004 and the launch of the first phase of the Coastal Security Scheme (CSS) in 2005.

However, it was the catastrophic 26/11 Mumbai terror attacks in 2008—where heavily armed Lashkar-e-Taiba operatives infiltrated undetected via the hijacked Indian trawler Kuber—that shattered existing complacency. The attacks exposed acute jurisdictional ambiguities, intelligence failures, and catastrophic gaps in coastal surveillance. The aftermath of 26/11 catalyzed a paradigm shift, prompting the Government of India to comprehensively restructure its maritime security apparatus, shifting from a reactive and fragmented approach to an integrated, multi-layered defensive posture.

The Three-Tier Coastal Security Grid

To eliminate overlaps and ensure seamless surveillance from the shoreline to the high seas, India established a three-tiered security architecture based on territorial depth.

The Inner Ring: State Marine Police and the Coastal Security Scheme (CSS)

Operating closest to the shore, the State Marine Police are mandated to patrol the shallow waters and serve as the critical interface with local coastal communities. Recognizing their initial lack of infrastructure, the Ministry of Home Affairs implemented the Coastal Security Scheme (CSS) to rapidly build capacity.

The CSS was executed in phases:

• CSS Phase I (2005-2011): Focused on foundational infrastructure, resulting in the establishment of 73 coastal police stations, primarily aimed at bridging immediate capability gaps.
• CSS Phase II (2011-2020): Formulated on the basis of a comprehensive vulnerability and gap analysis conducted post-26/11. Supported by a financial outlay of Rs. 1,580 crore, Phase II sanctioned the construction of 131 Marine Police Stations, 60 jetties, 10 Marine Operations Centres, and the procurement of over 429 specialized boats and numerous rigid inflatable boats (RIBs) and vehicles across 13 coastal states and UTs.

Despite substantial central funding, the Marine Police continue to face operational hurdles, including acute manpower shortages, a lack of specialized combat training, and poor maintenance of interceptor craft, occasionally relying on distant fisheries jetties rather than dedicated police infrastructure.

The Middle Ring: Indian Coast Guard (ICG)

Established formally by the Coast Guard Act of 1978 following the recommendations of the Rustamji Committee, the Indian Coast Guard (ICG) operates under the Ministry of Defence. In the post-26/11 reorganization, the Director-General of the ICG was designated as the Commander of Coastal Command, entrusted with the nodal responsibility for coordinating coastal security between central and state agencies.

The ICG maintains the Coastal Surveillance Network (CSN), a formidable chain of static radars, Automatic Identification System (AIS) receivers, and day/night electro-optic sensors spanning the mainland and island territories. This network ensures continuous electronic surveillance of highly sensitive maritime zones. Additionally, the ICG serves as the Lead Intelligence Agency (LIA) for coastal borders and operates as the National Maritime Search and Rescue Coordinating Authority (NMSARCA), managing operations through major Maritime Rescue Coordination Centres (MRCCs).

The Outer Ring: Indian Navy and the Sagar Prahari Bal (SPB)

The Indian Navy was formally designated as the authority bearing overall responsibility for India's maritime security, encompassing both coastal and offshore domains. While its primary focus remains blue-water power projection, it recognized the critical need to secure its own vulnerable assets—dockyards, ports, and naval bases—without permanently tying down frontline combatant vessels.

To execute this localized mandate, the Navy raised a specialized force in 2009 known as the Sagar Prahari Bal (SPB), which translates to "Ocean Sentinel Force". Comprising between 1,000 to 2,000 naval personnel, the SPB is equipped with approximately 80 Fast Interception Craft (FICs). Operating under the regional Naval Commands, the SPB's mandate is strictly defensive: executing continuous patrols of harbor mouths, screening incoming vessels, and providing immediate quick-reaction capabilities against asymmetrical waterborne intrusions, such as explosive-laden small craft.

Apex Coordination and Information Fusion Mechanisms

To dismantle the institutional silos that historically obstructed rapid responses, India instituted a network of apex coordinating bodies, data fusion centers, and specialized training academies.

National Committee for Strengthening Maritime and Coastal Security (NCSMCS)

Constituted in the immediate aftermath of 26/11, the NCSMCS is the paramount policy-making body for coastal security. Chaired by the Cabinet Secretary, it periodically reviews the implementation of the layered security architecture, resolves inter-agency jurisdictional disputes, sanctions vital infrastructure, and provides policy recommendations directly to the Cabinet Committee on Security.

National Maritime Security Coordinator (NMSC)

To provide continuous executive oversight between the periodic meetings of the NCSMCS, the government approved the creation of the National Maritime Security Coordinator. Operationalized in early 2022 under the National Security Council Secretariat (NSCS), the NMSC serves as the principal advisor to the government on maritime security, bridging the historical divide between civilian maritime entities (shipping, ports, fisheries) and the military domain. Vice Admiral G. Ashok Kumar was appointed as the inaugural NMSC, succeeded in 2025 by Vice Admiral Biswajit Dasgupta.

Data Fusion: IMAC and IFC-IOR

The generation of comprehensive Maritime Domain Awareness (MDA) is anchored by two critical, co-located centers in Gurugram, Haryana.

National Academy of Coastal Policing (NACP)

Recognizing the acute deficit in specialized training for state marine police, the Bureau of Police Research and Development (BPR&D), in collaboration with central forces, piloted the National Academy of Coastal Policing (NACP). Situated on a sprawling 450-acre campus in Okha, Devbhoomi Dwarka (Gujarat), and constructed at a cost of Rs. 470 crore, the NACP is India's first dedicated coastal policing academy. Partnering with the Rashtriya Raksha University, the academy provides rigorous training in maritime law, seamanship, navigation, weapons handling, and survival skills, with an ambitious throughput capacity designed to train 3,000 personnel annually.

Analytical Aspects: Evolving Maritime Threats

The contemporary maritime threat matrix has evolved significantly from conventional state-on-state naval engagements to a complex spectrum of asymmetric, geopolitical, and non-traditional challenges.

Geopolitical Encirclement: China's "String of Pearls"

The most profound strategic threat in the IOR emanates from China's rapidly expanding maritime footprint. Analysts characterize this expansion through the String of Pearls hypothesis—a geopolitical framework describing China's systematic development of a network of dual-use commercial ports, economic corridors, and military facilities along the Indian Ocean periphery, deeply intertwined with the Belt and Road Initiative (BRI).

Prominent "Pearls" encircling India include:

• Gwadar Port (Pakistan): Serving as the terminus for the China-Pakistan Economic Corridor (CPEC), this deep-water port provides China direct access to the Arabian Sea, strategically located just 400 kilometers from the critical Strait of Hormuz.
• Hambantota Port (Sri Lanka): Acquired by China on a 99-year lease following a textbook case of debt-trap diplomacy, this facility places Chinese maritime assets uncomfortably close to India's southern strategic installations.
• Chittagong and Mongla Port (Bangladesh): China has intensified efforts to develop economic zones and port facilities in Bangladesh. The recent agreement regarding Mongla Port—located mere kilometers from the sensitive Sunderbans and India's vulnerable Siliguri Corridor—amplifies concerns regarding a two-front security threat and intelligence surveillance.
• Kyaukphyu (Myanmar) and Djibouti: Providing strategic depth in the Bay of Bengal and a formalized naval base in the Horn of Africa, respectively.

Adding to this infrastructure expansion is the persistent deployment of Chinese 'research vessels' (such as the Yuan Wang class) throughout the IOR. Operating ostensibly for scientific purposes, these vessels map seabed terrain, acoustic profiles, and salinity levels—data that is exceptionally critical for advancing submarine warfare capabilities and tracking Indian missile tests, thereby directly undermining India's strategic autonomy.

Resource Competition: Critical Minerals and the Seabed Race

The Indian Ocean is rapidly becoming a contested frontier for critical minerals essential for emerging technologies, electric vehicles, and defense manufacturing. The ocean floor is rich in polymetallic nodules and sulphides (containing manganese, nickel, cobalt, and copper).

India proactively secured "Pioneer Investor" status from the International Seabed Authority (ISA) in 1987, granting it access to a 75,000-square-kilometer nodule block in the Central Indian Ocean Basin. Recently, India became the first nation to hold two ISA polymetallic-sulphide contracts, encompassing massive exploration zones over the Carlsberg Ridge. However, China's aggressive pursuit of similar licenses transforms the ocean floor into a strategic battleground, shifting competition from the surface to the seabed.

Territorial and Border Disputes: The Sir Creek Conflict

In the realm of direct territorial contestation, the Sir Creek dispute between India and Pakistan remains a volatile flashpoint with immense strategic and economic implications. Sir Creek is a 96-kilometer tidal estuary situated in the marshlands of the Rann of Kutch (Gujarat), separating it from Pakistan's Sindh province, before opening into the Arabian Sea.

The origin of the dispute traces back to a contradictory 1914 resolution between the Government of Bombay (under British India) and the Ruler of Sindh.The resolution of Sir Creek directly governs the demarcation of the maritime boundary and the subsequent Exclusive Economic Zone (EEZ). Yielding to Pakistan's eastern-bank claim would cost India approximately 250 square miles of EEZ, an area suspected to hold vast untapped oil and gas reserves, alongside serving as one of Asia's most lucrative fishing grounds. Strategically, control of the creek regulates maritime access near Karachi, and misadventures in this asymmetric terrain—which is plagued by shifting mudflats and seasonal flooding—could rapidly escalate into broader military confrontations, prompting firm warnings from India's defense establishment.

Asymmetric, Transnational, and Non-Traditional Threats

Beyond state-centric rivalries, India confronts a multitude of transnational threats:

• Maritime Terrorism: Terrorist syndicates have repeatedly exploited the maritime domain. While 26/11 is the most prominent example, the threat persists regarding potential attacks on critical coastal infrastructure, such as nuclear installations, oil rigs, and major ports, which could cripple the national economy.
• Smuggling and Trafficking: The vast and occasionally porous coastline facilitates the illicit trafficking of arms, narcotics, and humans. The proximity to global drug production hubs requires constant interdiction efforts by the Coast Guard and Marine Police.
• IUU Fishing (Illegal, Unreported, and Unregulated): Heavily subsidized foreign deep-sea trawlers routinely breach India's EEZ. IUU fishing devastates fragile marine ecosystems, jeopardizes the livelihoods of local fishing communities, and often serves as a clandestine cover for intelligence gathering.
• Cyber and Environmental Vulnerabilities: The digital integration of maritime logistics introduces severe cyber vulnerabilities. Attacks targeting port operations, navigation networks (e.g., GPS spoofing), and undersea optical cable networks represent modern vectors of sabotage. Furthermore, climate change exacerbates security challenges through rising sea levels and an increased frequency of severe cyclones, which threaten coastal installations and alter baseline topographies.

Strategic Economic Imperatives and Shipbuilding

Maritime security is inextricably linked to maritime industrial capacity. A robust shipbuilding sector is fundamental to maintaining naval superiority and securing supply chains. Historically hampered by low production capacity, high financing costs, and a reliance on imported components, India's shipbuilding output remains marginal compared to global leaders.

To reverse this, the government launched the Maritime India Vision 2030 (aiming to position India among the top 10 shipbuilding nations) and the Maritime Amrit Kaal Vision 2047 (aiming for the top five). Strategic initiatives include the establishment of the Sagarmala Finance Corporation Limited (India's first dedicated maritime-sector NBFC) and the Maritime Development Fund to attract institutional capital. A critical vector for this expansion is strategic alignment with advanced manufacturing nations, notably South Korea. By adopting South Korea's highly integrated "Ulsan model"—which synchronizes shipyards, ancillary industries, research centers, and logistics—India seeks to localize marine supply chains, absorb advanced technologies (such as green propulsion and modular construction), and ensure strategic autonomy in both commercial and naval shipbuilding.

Evolving Maritime Doctrines and Diplomacy (2024-2026)

To systematically navigate this increasingly volatile environment, India has fundamentally overhauled its strategic naval doctrines and diplomatic outreach frameworks.

Doctrinal Shifts: IMD-25 and INMSS-2026

The Indian Navy recently promulgated two capstone documents that redefine its operational philosophy.

• Indian Maritime Doctrine 2025 (IMD-25): IMD-25 introduces profound conceptual updates, departing from traditional binary views of conflict and peace.
  • No War, No Peace (NWNP): The doctrine formalizes the NWNP operational category, acknowledging that modern geopolitics is defined by prolonged strategic stalemates, hybrid warfare, and grey-zone operations. In an NWNP scenario, the Navy must maintain heightened readiness to mount calibrated kinetic responses to influence adversary behavior without triggering total mobilization.
  • Multi-Domain Operations (MDO): Recognizing that maritime superiority cannot be achieved in isolation, IMD-25 defines MDO as the synchronized application of capabilities across Land, Sea, Air, Space, Cyber, and Cognitive domains to secure decisive control.
• Indian Navy Maritime Security Strategy 2026 (INMSS-2026): Serving as the strategic roadmap for IMD-25, the INMSS-2026 adopts a rigorous Ends-Ways-Means-Risks framework, acknowledging that expanding maritime ambitions must be meticulously balanced against finite resources and organizational capacity.
  • Sub-Conventional Deterrence: To counter proxy and deniable coercion, INMSS-2026 elevates sub-conventional deterrence alongside conventional and nuclear deterrence. In a bold declaratory shift, it explicitly states that India's nuclear posture will not constrain its response options against acts of state-sponsored maritime terrorism.
  • Technological Integration: The strategy establishes protocols for the systematic integration of Artificial Intelligence (AI), autonomous unmanned systems, and robotics to maintain a decisive operational edge.

Diplomatic Outreach: From SAGAR to MAHASAGAR

Diplomatically, India's foundational doctrine of SAGAR (Security and Growth for All in the Region, 2015) has matured into the MAHASAGAR framework (Mutual and Holistic Advancement for Security and Growth Across Regions), unveiled in 2025.

MAHASAGAR represents a subtle but vital shift from India acting as a hierarchical "net security provider" to engaging as an equitable, consultative "partner" prioritizing sovereign equality, mutual respect, and institutional trust. This approach integrates military security with sustainable Blue Economy practices, digital transformation (e.g., UPI infrastructure), and climate resilience.

A paramount example of MAHASAGAR in action is India's engagement with Seychelles, a critical strategic node in the Western Indian Ocean. Recognizing Seychelles' proximity to vital SLOCs, India extended a massive Special Economic Package worth $175 million (including a Rs. 1,250 crore Line of Credit). In tandem with infrastructure funding, India bolstered Seychelles' maritime defense by gifting defense assets, including the refit of the PS Zoroaster, fast attack vessels, and Advanced Light Helicopters (ALH), while integrating their radar feeds into India's MDA network via the Regional Operations Coordination Centre (RCOC). Furthermore, India aligns with UNHRC-mandated commissions of inquiry to ensure accountability for violations of international humanitarian law, leveraging multilateral institutions to reinforce rules-based maritime order.

Coastal Security Exercises and Validation

Standard Operating Procedures (SOPs) within this complex architecture are continuously validated through rigorous, multi-agency simulations.

• Exercise Sea Vigil: Originally conceptualized in 2018, Sea Vigil is a biennial, pan-India coastal defense exercise that assesses the entire 11,098 km coastal and island perimeter. The unprecedented Sea Vigil-24 involved 6 ministries and 21 agencies. Notably, officials from the National Security Council Secretariat (NSCS) participated alongside the Navy and Coast Guard in auditing critical infrastructure, evaluating defenses at ports, oil rigs, and cable landing stations.
• Sagar Kavach: A recurrent, state-level exercise led by the ICG that simulates asymmetric threats. The exercise employs a "Red Force" to simulate infiltrators attempting to breach the coast, while a "Blue Force" establishes surveillance and interdiction barriers. A critical component of Sagar Kavach is community integration, actively mobilizing local fishermen to serve as vigilant "eyes and ears".

Structural Vulnerabilities and the Way Forward

While India has constructed a formidable coastal security apparatus, critical structural vulnerabilities persist that require urgent policy interventions.

• Resolving Governance and Command Ambiguities: Despite the NMSC's establishment, jurisdictional overlap between the Navy, ICG, and Marine Police frequently obstructs seamless real-time coordination. Applying the principles of the Madhukar Gupta Committee—which investigated border protection—the government must implement a doctrine of 'single point control' across distinct maritime sectors to streamline the chain of command.
• Implementation of CIBMS and Technological Domination: The Madhukar Gupta Committee's recommendation to deploy a Comprehensive Integrated Border Management System (CIBMS) must be fully extended to the maritime domain. Utilizing solutions like BOLD-QIT (Border Electronically Dominated QRT Interception Technique), the state must secure unfenced, shallow riverine terrains and creek areas using infrared sensors, underground/underwater monitoring systems, and advanced drone detection radars.
• Comprehensive Legislative Framework: India requires a unified, statutory maritime security law. Current legislation is fragmented, creating accountability vacuums among state maritime boards, private port terminal operators, and central agencies. A comprehensive framework must mandate minimum port security standards, compulsory AIS fitment for all vessels irrespective of length, and stringent maritime cybersecurity protocols.
• Empowering the Marine Police: Rather than creating a new Central Armed Police Force (CAPF) for the coast, authorities must aggressively empower the existing State Marine Police. This necessitates expanding the operational throughput of the NACP, resolving local manpower deficits, ensuring the availability of combat-ready interceptor craft, and providing legal authority for operations beyond immediate territorial waters when necessitated by hot pursuit.

Summary

The catastrophic 26/11 Mumbai attacks exposed profound vulnerabilities in India’s maritime domain, catalyzing a historic overhaul of the nation's coastal security architecture. Transitioning from institutional 'sea blindness,' India erected a robust three-tier security grid utilizing the State Marine Police, the Indian Coast Guard, and the Indian Navy. The establishment of dedicated units like the Sagar Prahari Bal ensures the close-in defense of high-value naval assets, while intelligence fusion centers—specifically IMAC for domestic coastal data and IFC-IOR for international white shipping coordination—generate comprehensive Maritime Domain Awareness. This vast network is harmonized by apex bodies such as the NCSMCS and the newly operationalized National Maritime Security Coordinator (NMSC).

However, the threat landscape continues to evolve rapidly. Beyond transnational issues like maritime terrorism, piracy, and IUU fishing, India faces severe geopolitical and territorial pressures. The Sir Creek dispute with Pakistan threatens sovereign control over resource-rich EEZs, while China’s expanding "String of Pearls" strategy and seabed mining ambitions challenge India’s primacy in the Indian Ocean. In response, India has updated its strategic posture through the IMD-25 and INMSS-2026 doctrines, embracing paradigms like 'No War, No Peace' (NWNP) and sub-conventional deterrence. Diplomatically, the MAHASAGAR vision transforms India into an equitable regional partner, prioritizing sovereign collaboration over paternalistic security provision. Moving forward, India must leverage advanced technological integration, resolve inter-agency jurisdictional friction, and modernize its shipbuilding sector to secure its maritime frontiers definitively.
