Maritime Security in India
India, with its vast coastline of over 7,500 km and strategic location in the Indian Ocean Region (IOR), faces multifaceted maritime security challenges. The Indian Ocean is not only a vital trade corridor—carrying nearly 90% of India’s trade by volume and the bulk of its energy imports—but also a theatre of geopolitical competition, piracy threats, illegal fishing, terrorism, and climate-induced vulnerabilities. Securing India’s maritime domain is therefore essential to safeguard economic interests, ensure energy security, protect marine resources, and uphold its strategic role as a net security provider in the IOR.
Length of India’s Coastline
The length of India’s coastline of 7516.6 km has been re-assessed to 11098.81 km by National Hydrographic Office (NHO) in coordination with Survey of India (SoI) as per the latest terms of references provided by National Security Council Secretariat (NSCS).
Maritime Security
Maritime security involves protecting the nation’s sovereignty from threats arising from the oceans and seas. It includes protecting coastal areas, safeguarding the available ocean resources such as fish, offshore oil and gas wells, port facilities, etc. It also means maintaining freedom at sea for movement of our ships and facilitating and protecting trade.
Elements of maritime security:
- International and national peace and security
- Protection of sea lanes of communication
- Sovereignty, territorial integrity and political independence
- Protection from crime at sea
- Access and security to the resources at sea
- Security of seafarers and fishermen
- Environmental protection
Importance of Maritime Security
- Economic Lifeline and Trade Security
- Trade Dependence: Over 95% of India’s trade by volume and 70% by value moves by sea. This includes vital imports like crude oil, fertilizers, and electronics, and exports like refined petroleum, pharmaceuticals, and agricultural products. Any disruption to Sea Lanes of Communication (SLOCs) due to piracy, conflict, or blockade would have an immediate and catastrophic impact on India’s economy, leading to inflation, shortages, and social unrest.
- Energy Security: The Fuel for Growth
- Lifeblood of the Economy: India is the world’s third-largest consumer of oil and relies on imports for over 85% of its crude oil needs. The vast majority of this, along with liquefied natural gas (LNG), is transported via the Indian Ocean from the Persian Gulf and Africa.
- Vulnerable Chokepoints: These energy flows must pass through critical maritime chokepoints like the Strait of Hormuz and the Strait of Malacca. Any conflict or instability in these regions—such as Houthi attacks in the Red Sea or a U.S.-Iran confrontation—directly threatens India’s energy supply, making maritime security a non-negotiable aspect of its energy policy.
- National Security and Territorial Integrity
- The Two-Front Challenge: India faces a unique combination of state-led maritime threats.
- China’s String of Pearls: China’s strategy of establishing dual-use ports around India (e.g., Gwadar, Hambantota, Djibouti) and its frequent deployment of submarines and warships in the Indian Ocean are perceived as strategic encirclement, challenging India’s natural dominance in its home waters.
- Pakistan’s Asymmetric Threat: The persistent threat of sea-borne terrorism, exemplified by the 26/11 Mumbai attacks, and the modernization of the Pakistan Navy with Chinese help, require constant vigilance and robust coastal defense.
- Securing the Island Territories: Protecting the Andaman and Nicobar and Lakshadweep island chains is crucial. These islands are not just territories but provide India with strategic depth, acting as unsinkable aircraft carriers that allow it to monitor and control key chokepoints like the Strait of Malacca.
- Resource Security: The Blue Economy
- Harnessing the “Blue Economy”: India’s EEZ is rich in living and non-living resources. Maritime security is a prerequisite for safely harnessing this potential, which includes:
- Fisheries: Combating Illegal, Unreported, and Unregulated (IUU) fishing by foreign trawlers is essential to protect the livelihoods of millions of Indian fishermen and ensure national food security.
- Offshore Energy & Minerals: Securing offshore oil and gas blocks and future deep-sea mining sites (e.g., for polymetallic nodules) is vital for economic growth and resource independence.
- Projecting Influence: The “Net Security Provider” Doctrine
- Strategic Autonomy and Leadership: India’s official maritime doctrine positions it as the “Net Security Provider” in the Indian Ocean Region. This means ensuring stability and security for smaller neighbors and preventing external powers from dominating the region.
- Diplomacy and Soft Power: A strong and responsible navy allows India to conduct Humanitarian Assistance and Disaster Relief (HADR) missions, anti-piracy patrols, and joint exercises (like MALABAR). These actions build immense goodwill, strengthen diplomatic ties (e.g., with ASEAN, Indian Ocean littoral states), and enhance India’s strategic profile
- Protecting Critical Infrastructure
- India’s maritime domain is dotted with critical infrastructure that is vulnerable to sabotage or attack. This includes:
- Major ports like JNPT, Mundra, and Chennai.
- Offshore oil and gas platforms.
- Underwater communication cables that carry over 95% of India’s international data traffic.
- A breach in the security of any of these assets would have severe economic and strategic consequences.
- Environmental and Disaster Security
- Oil spills, marine pollution, and natural disasters (tsunamis, cyclones) can cripple coastal economies.
- Maritime security includes preparedness for humanitarian assistance and disaster relief (HADR).
- National Security and Counterterrorism
- The 26/11 Mumbai attacks highlighted vulnerabilities from the sea.
- Preventing infiltration, smuggling of arms, and maritime terrorism requires robust coastal and port security.
- India has a coastline of 7,517 kms. This vast coast line presents numerous security challenges like piracy, illegal landing of arms and explosives, infiltration, use of sea and off shore islands for criminal activities, drug and human trafficking and smuggling.
- Absence of physical barriers on the coast and presence of vital industries like port and important defence installations like RADARs and nuclear reactors enhances the risk and the need to protect its maritime region
- Food and Livelihood Security
- Fishing and marine resources provide livelihood to over 4 million people in India.
- Securing maritime zones prevents illegal, unregulated, and unreported (IUU) fishing that threatens livelihood security.
Maritime Security Challenges Faced by India
Non-Traditional / Non-State Challenges
- Piracy and Armed Robbery
- Piracy in the Indian Ocean: Although piracy incidents have reduced over the years, the Indian Ocean remains vulnerable, particularly in regions like the Gulf of Aden and off the coast of Somalia. These areas are crucial for Indian maritime trade, with a significant percentage of the country’s oil imports passing through these waters.
- Armed Robbery: Closer to home, incidents of armed robbery against ships occur, particularly in the waters off the coast of Southeast Asia and near the Andaman and Nicobar Islands.
- Although piracy and armed robbery against ships do not constitute a major issue in the Bay of Bengal and Andaman Sea
- Although piracy off the Somali coast has declined from its peak, it remains a latent threat. More recently, the focus has shifted to the Strait of Hormuz and the Singapore Strait, where armed robberies against ships threaten Indian seafarers and commercial interests.
- Terrorism
- Sea-Borne Terrorism: The 2008 Mumbai attacks highlighted the vulnerability of India’s coastal areas to sea-borne terrorism. Terrorists exploited the porous coastal security to infiltrate the city, leading to significant loss of life and property.
- The potential for terrorist groups like Lashkar-e-Taiba (LeT) to use the maritime domain for attacks, either against port cities, offshore infrastructure, or commercial vessels, is a constant concern. Attacks on vessels, such as the MV Chem Pluto near India’s coast, highlight this ongoing threat.
- Potential Threats: The presence of terrorist networks in neighboring countries, combined with inadequate coastal surveillance, continues to pose a threat of sea-borne terrorist attacks.
- Smuggling and Trafficking
- Drug Smuggling: The maritime routes are increasingly used for drug trafficking, particularly from the Golden Crescent and Golden Triangle regions. The vast coastline and numerous ports make it challenging to monitor all illegal activities.
- Arms Smuggling: Maritime routes are also used for the smuggling of arms and ammunition, often intended for insurgent and terrorist groups operating within India.
- Human Trafficking: The sea route is used for illegal migration and human trafficking.
- Illegal, Unreported, and Unregulated (IUU) Fishing
- Threat to Marine Resources: IUU fishing poses a threat to India’s marine resources, leading to economic losses and potential conflicts with neighboring countries over fishing rights.
- Economic Impact: IUU fishing not only depletes fish stocks but also affects the livelihoods of Indian fishermen, leading to socio-economic issues in coastal communities.
- Security of Critical Offshore Infrastructure:
- India has a vast network of offshore oil and gas platforms, pipelines, and underwater cables. These are critical for energy and communications and are vulnerable to sabotage, accidental damage, or terrorist attacks.
- Natural Disasters and Environmental Threats
- Cyclones and Tsunamis: The Indian coastline is vulnerable to natural disasters such as cyclones and tsunamis, which can devastate coastal infrastructure and displace large populations.
- Environmental Degradation: Pollution, coral reef destruction, and rising sea levels due to climate change threaten India’s maritime security by affecting coastal ecosystems and economies.
Traditional / State-Centric Challenges
These involve challenges posed by the military and strategic actions of other nation-states.
- Chinese Naval Expansionism in the Indian Ocean:
- String of Pearls Strategy: China’s perceived strategy of establishing a network of military and commercial facilities in the IOR (e.g., Gwadar in Pakistan, Hambantota in Sri Lanka, Djibouti in the Horn of Africa) is seen as an attempt to encircle India and project power.
- Regular Submarine and Warship Deployments: The frequent presence of Chinese nuclear and conventional submarines in the Indian Ocean undermines India’s traditional naval dominance in its backyard.
- China currently has the world’s largest navy with 370 warships
- The Belt and Road Initiative (BRI): Maritime components of the BRI, like the 21st Century Maritime Silk Road, involve massive investments in port infrastructure across the region, raising concerns about these dual-use facilities potentially serving Chinese military logistics in times of conflict.
- India-China Border Dispute: The simmering territorial dispute along the Himalayan border has a direct maritime dimension, with the Indian Ocean becoming a secondary theater for strategic competition and potential leverage.
- Pakistan-Based Threats:
While the Pakistan Navy is quantitatively smaller, it poses a persistent challenge through asymmetric means and its strategic partnership with China. - Sea-Borne Terrorism: The memory of the 2008 Mumbai attacks, launched by terrorists who arrived via the sea, remains a stark reminder of this vulnerability. Preventing a repeat of such an event is a paramount security concern.
- Modernization of Pakistan Navy: With Chinese assistance, Pakistan is modernizing its fleet with new frigates, submarines, and long-range cruise missiles, enhancing its ability to threaten Indian sea lines of communication and naval assets.
- China is assisting Pakistan by providing eight Hangor/Yuan-class diesel-electric submarines equipped with air-independent propulsion (AIP), which allows submarines to stay submerged longer.
- Nuclearization at Sea: Pakistan’s development of a sea-based nuclear deterrent (Babur-class submarines) introduces a dangerous nuclear dimension to the maritime domain.
Gaps in Maritime Security
- Inadequate Surveillance and Infrastructure
- Limited Radar Coverage: The existing radar network along the coastline is not comprehensive, leading to gaps in monitoring maritime activities, especially in remote and isolated areas.
- The Coastal Surveillance Network (CSN) of radar stations does not provide seamless coverage of the entire coast, leaving blind spots.
- Insufficient Coastal Security: The vast coastline and numerous landing points are not adequately secured, making it difficult to prevent unauthorized landings and smuggling activities.
- Limited Aerial Surveillance: There are not enough long-range maritime patrol aircraft (LRMPA) and drones (UAVs) to maintain persistent surveillance over the EEZ and key shipping lanes.
- Coordination and Information Sharing
- Fragmented Command Structure: Multiple agencies, including the Indian Navy, Coast Guard, Marine Police, and intelligence agencies, are involved in maritime security. However, the lack of a unified command structure leads to coordination challenges.
- Unlike countries with a dedicated Coast Guard or a single maritime security agency, India lacks a unified command and control structure for all maritime agencies. This leads to duplicated efforts, jurisdictional conflicts, and slow response times during a crisis.
- Inadequate Information Sharing: There is a need for better real-time information sharing between various agencies involved in maritime security to respond effectively to threats.
- Identification and Tracking of Vessels
- The use of cheap Chinese-made Automatic Identification System (AIS) gadgets in Indian fishing trawlers creates serious maritime security risks. These devices often transmit wrong country codes, misidentifying Indian vessels as Chinese. This hampers coastal surveillance, confuses enforcement agencies like the Coast Guard, and opens vulnerabilities for illegal fishing, smuggling, or even infiltration under the cover of legitimate fishing activity.
- Dark Shipping: The ability to monitor vessels that have deliberately switched off their AIS (so-called “dark” ships) is limited, relying heavily on satellite imagery and intelligence, which may not be real-time.
- Lack of Awareness and Preparedness
- Community Involvement: Coastal communities, including fishermen, often lack awareness about maritime security threats. Their involvement in reporting suspicious activities is limited.
- Preparedness for Natural Disasters: Coastal states often lack adequate disaster preparedness and response mechanisms, exacerbating the impact of natural disasters on maritime security.
- Limited Naval and Coast Guard Capabilities
- Resource Constraints: Both the Indian Navy and Coast Guard face resource constraints, including a shortage of ships, aircraft, and personnel, which limits their ability to effectively patrol and secure India’s vast maritime domain.
- Aging Infrastructure: Some of the existing naval and Coast Guard assets are aging and require modernization to meet current and future maritime security challenges.
- Weak Marine Police Force: The coastal marine police, the first line of defense, are severely ill-equipped. They often lack boats, communication equipment, training, and even a basic understanding of the maritime domain. They function more as land police, rendering the concept of a layered defense ineffective.
- Legal and Regulatory Gaps
- Weak Maritime Governance: Laws regulating fishing, port security, and environmental protection are often outdated and poorly enforced. Penalties for violations are not stringent enough to act as a deterrent.
- Jurisdictional Ambiguity: Ambiguities in the roles and responsibilities of different agencies, especially between central and state authorities, can lead to confusion and inaction during security operations.
- Lack of a Maritime Mindset
- India has historically been a land-centric power. This “continental mindset” often leads to a lower political and bureaucratic priority for maritime security funding and policy attention compared to the army.
Measures to Improve Maritime Security
- Enhanced Surveillance and Monitoring
- Comprehensive Radar Coverage: Expand the coastal radar network to cover the entire coastline and integrate it with satellite-based surveillance to ensure real-time monitoring of maritime activities.

- Unified Maritime Command: Establish a unified maritime command to streamline coordination between the Navy, Coast Guard, and other relevant agencies, ensuring a more effective response to threats.
- Information Sharing Mechanisms: Develop robust mechanisms for real-time information sharing between all stakeholders involved in maritime security, including intelligence agencies and international partners.
- Capacity Building and Modernization
- Modernizing Naval and Coast Guard Assets: Invest in modernizing the Navy and Coast Guard fleets with new ships, submarines, aircraft, and unmanned systems to enhance patrolling and response capabilities.
- Indigenization: Pushing the “Make in India” initiative in defense to build ships and submarines faster
- Expanding Maritime Infrastructure: Develop and upgrade maritime infrastructure, including ports, naval bases, and logistics hubs, to support sustained operations and rapid response.
- Infrastructure Modernization: Developing strategic bases like the INS Kohassa in the Andamans and upgrading port infrastructure.
- Strengthening International Cooperation
- Collaborative Patrols and Exercises: Engage in joint patrols, naval exercises, and information sharing with regional and global partners to address common maritime security challenges.
- Multilateral Frameworks: Actively participate in multilateral forums like the Indian Ocean Rim Association (IORA) and the ASEAN Regional Forum (ARF) to promote regional maritime security cooperation.
- Deepening partnerships through forums like the Quad, IORA, and bilateral agreements for information sharing and capacity building.
Steps taken by India
Since ‘26/11’ the Government has taken a number of measures to strengthen coastal, offshore and maritime security. Broadly, these measures include capacity augmentation of maritime security agencies for surveillance and patrol of the nation’s maritime zones; enhanced technical surveillance of coastal and offshore areas; establishment of mechanisms for inter-agency coordination; increased regulation of activities in the maritime zones; as also integration of the fishing and coastal communities. Besides, State-wise Standard Operating Procedures (SOPs) for coordination among various agencies on coastal security issues have been formulated. Coastal Security Exercises are being conducted regularly by the Indian Navy and Indian Coast Guard to assess the effectiveness of existing mechanisms and to address gaps.
- National Committee for Strengthening Maritime and Coastal Security (NCSMCS): Chaired by the Cabinet Secretary, this is the apex body for coordinating all maritime security activities among the Navy, Coast Guard, State Police, and central ministries.
- Coastal Security Scheme: Multiple phases of this scheme have been funded to strengthen the infrastructure of coastal police forces by providing boats, jeeps, training facilities, and coastal police stations.
- The SAGAR Doctrine
- Introduced in 2015, Security And Growth for All in the Region is India’s strategic maritime vision. It positions India as a “net security provider” and a benevolent leader in the Indian Ocean Region, emphasizing capacity building, regional cooperation, and sustainable development.
- Information Management for Fisheries (IMF)
- To track fishing vessels, a mandatory fitment of Automatic Identification System (AIS) transponders on all mechanized fishing boats has been enforced. This integrates them into the coastal surveillance network, distinguishing them from potential hostile vessels.
- Naval Modernization and Indigenization
- The Indian Navy aims to expand its fleet to more than 200 ships and submarines by 2035, with the possibility of reaching 230 vessels by 2037
- At present, the Navy operates 140 warships, including 17 diesel-electric submarines (11 of them very old) and two nuclear-powered ballistic submarines (SSBNs). Its aviation wing has over 250 aircraft and helicopters.
- Deal with France for 26 Rafale marine fighters to operate from aircraft carriers
- Currently, 55 warships are under construction in Indian shipyards
- Shipbuilding: A focus on domestic construction under the “Make in India” initiative. Key projects include:
- Indigenous Aircraft Carrier (IAC): INS Vikrant, which entered service, making India one of the few nations with indigenous carrier capability.
- India is developing its own carrier-based fighter, the TEDBF (Twin Engine Deck-Based Fighter), to enhance its indigenous capabilities.
- Strengthening the Indian Coast Guard (ICG)
- The ICG has seen a massive expansion, recognizing its role as the primary coastal security agency.
- Acquisition of Vessels and Aircraft: Rapid induction of Offshore Patrol Vessels (OPVs), Fast Patrol Vessels (FPVs), interceptor boats, and Dornier aircraft.
- Enhanced Operational Reach: Establishment of new stations along the coast, including in the Lakshadweep and Andaman & Nicobar Islands.
- Tri-Service Command in the Andamans
- The Andaman and Nicobar Command (ANC) is India’s first and only tri-service theater command. Its strategic location at the mouth of the Strait of Malacca allows India to monitor and project power into the vital Southeast Asian sea lanes.
- Coastal Surveillance Network (CSN)
- A chain of static radar sensors has been installed along India’s entire coast and island territories. These radar stations provide real-time low-level coverage of coastal waters, detecting and tracking surface vessels.
- Electronic surveillance mechanism has been augmented by provisioning of an electronic / radar chain called Coastal Surveillance Network (CSN) comprising of Chain of Static Sensors having radar, Automatic Identification System (AIS), Long Range Identification and Tracking (LRIT), day / night cameras, communication systems
- Vessel Traffic Management System (VTMS) radars in ports facilitate surveillance of port areas.
- National Command Control Communication and Intelligence Network (NC3I)
- This is the technological backbone that networks the CSN radars, AIS data, and other sensors. The Information Management and Analysis Centre (IMAC) in Gurugram is the nerve center of the NC3I, fusing this data to create a common, real-time operational picture for all authorized agencies.
- Space-Based Monitoring
- India leverages its robust space program to support maritime security.
- RISAT Satellites: The RISAT (Radar Imaging Satellite) series, with its all-weather, day-and-night surveillance capability, is crucial for monitoring large ocean areas, including tracking “dark” ships with switched-off transponders.
- Bilateral and Multilateral Exercises
- India actively engages with friendly navies to build interoperability and trust.
- Bilateral: Exercises like VARUNA (France), KONKAN (UK), INDRA (Russia), and AUSINDEX (Australia).
- Multilateral: The MALABAR exercise with the US and Japan (and now regularly including Australia) has become a cornerstone of maritime cooperation in the Indo-Pacific, signaling a strong strategic alignment.
- The Quad (Quadrilateral Security Dialogue):
Alongside the US, Japan, and Australia, India uses the Quad to promote a “Free and Open Indo-Pacific.” A key focus is on maritime security cooperation, HADR, and countering disinformation, providing a strategic counterweight to Chinese expansionism.
- Regional Outreach and Capacity Building
- Through SAGAR, India sought to brand itself as a net security provider in the IOR by offering lesser developed countries like Sri Lanka, the Maldives, Seychelles, and Mauritius naval aid, intelligence, and other assistance services.
- Mahasagar Initiative: During his latest trip to Mauritius, Prime Minister Narendra Modi outlined that the MAHASAGAR initiative seeks to expand India’s influence in the Global South by encouraging trade, security cooperation, and sustainable development. This represents a shift in strategy to meet China’s growing engagement in the Indo-Pacific and the Indian Ocean Region, which gives New Delhi larger leadership in regional governance.
- White Shipping Agreements: Agreements to exchange information on commercial vessel traffic with IOR countries, enhancing the overall Maritime Domain Awareness (MDA) picture.
Maritime security is no longer confined to protecting India’s coastline; it has become a central pillar of national security, economic growth, and global strategy. With increasing dependence on sea-borne trade and energy imports, coupled with the rise of China’s assertiveness and asymmetric threats like terrorism and piracy, India’s maritime strategy must evolve into a comprehensive framework of surveillance, capacity building, and international cooperation. Through initiatives like SAGAR, strengthening the Navy and Coast Guard, leveraging space-based monitoring, and enhancing regional partnerships such as the Quad, India is moving towards securing its maritime domain. A robust maritime security posture not only ensures economic and energy security but also cements India’s role as a net security provider in the Indian Ocean Region.
