Water is the major source of life and occupies a major portion of the earth's surface. We categorize this water into oceans and seas. An ocean is a large water body of saline water, whereas seas are large bodies of water which may or may not be connected, and most seas are fully or partially enclosed by land. To date, mankind has explored only five percent (5%) of the total area covered by oceans.
Today, the economic growth of nations depends heavily on oceans because it is through these large water bodies that international trade is conducted, and imports and exports of vital products, oil, and gas are shipped. Securing such maritime activity is known as Maritime Security. In view of this immense importance, nation-states give high priority to securing the Sea Lanes of Communication (SLOC) to protect their economy, secure their borders, safeguard trade routes, and project national strength.
Core Definition: Maritime security involves protecting the nation's sovereignty from threats arising from the oceans and seas. It encompasses protecting coastal areas, safeguarding available ocean resources (such as fish, offshore oil and gas wells, and port facilities), maintaining freedom at sea for the movement of ships, and facilitating and protecting trade.
Seven Core Elements of Maritime Security:
- International and national peace and security
- Protection of sea lanes of communication (SLOC)
- 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
Just as nations face security threats on land borders, severe vulnerabilities exist across oceans and seas. The textbook identifies eight explicit maritime threats:
- Illegal maritime arrivals / terrorists: Infiltration of armed elements via sea routes.
- Illegal exploitation of natural resources: Unlawful harvesting of marine living and non-living wealth.
- Illegal activity in protected areas: Violations in reserved marine habitats and ecologically sensitive zones.
- Marine pollution: Dumping of toxic waste, chemical discharge, and accidental oil slicks damaging the marine ecosystem.
- Prohibited imports and exports (Smuggling): Contraband, narcotics, arms, and illegal goods moved by sea.
- Compromise to biosecurity: Introduction of harmful alien biological agents, invasive species, or pathogens into coastal waters.
- Piracy, robbery, or violence at sea: Armed attacks on commercial shipping, hijacking of vessels, and kidnapping of crew.
- Maritime terrorism: Coordinated strikes against offshore installations, ports, or coastal metropolitan targets using maritime routes.
States that have access to the sea are classified as coastal states. India is classified geographically as a peninsula because it has huge waterways surrounding its landmass on three sides. Such coastal states possess sovereign rights to utilize all surrounding waterways for two primary purposes:
- To explore, exploit, and manage natural resources in the seabed for economic purposes.
- To establish rights over the use of artificial islands, installations, and structures for marine scientific research.
Textbook Measurement Standard — The Nautical Mile:
A Nautical Mile (NM) is a standard unit of measurement used at sea or in air navigation. One Nautical Mile is equal to 1,852 metres or 1.852 km.
The maritime zones recognized under international law (1982 United Nations Convention on the Law of the Sea) are measured seaward from a coastal state’s baseline:
- Internal Waters: Waters situated on the landward side of the baseline from which the distance of the territorial sea is measured. Coastal states possess full and complete sovereignty over internal waters. Internal waters are legally considered an integral part of the land territory.
- Territorial Sea: Coastal states can claim up to 12 nautical miles from their baseline. The coastal state exercises complete sovereignty and authority over the territorial sea, the airspace above it, and the seabed and subsoil beneath it.
- Contiguous Zone: An adjacent zone claimed beyond the territorial sea that extends seaward up to 24 nautical miles from the baseline. Within this zone, coastal states possess the legal authority to exercise customs, fiscal, immigration, or sanitary laws and prevent or punish infringements of their regulations.
- Exclusive Economic Zone (EEZ): Extends beyond and adjacent to the territorial sea up to 200 nautical miles seaward from the baseline (or out to an agreed maritime boundary with an opposite or adjacent coastal state). The coastal state enjoys sovereign rights for exploring, exploiting, conserving, and managing natural resources of the waters, seabed, and subsoil.
- High Seas: The vast oceanic expanse lying beyond 200 nautical miles from shore. The High Seas are open and freely available to all countries of the world. On the High Seas, no state may validly purport to subject any part of them to its sovereignty, nor can any state act or interfere with other nations using the seas.
Under international law, the High Seas provide unconditional freedom of activity in exactly six recognized domains:
- Freedom of Navigation: Unrestricted passage for ships of all flags.
- Freedom of Overflight: Right of civil and military aircraft to fly across high seas airspace.
- Freedom of Laying Submarine Cables and Pipelines: Essential for international telecommunications and energy transport.
- Freedom to Construct Artificial Islands and Installations: Permitted subject to international legal standards.
- Freedom of Fishing: Subject to international conservation conditions and treaties.
- Freedom of Marine Scientific Research: Open scientific study for peaceful purposes.
Maritime trade occupies a foundational place in India's economy and national energy security. Most of India's international merchandise trade and crude energy supplies pass through the Indian Ocean Region (IOR). The textbook highlights that an estimated 95% of India’s trade is conducted through oceans. Consequently, securing the maritime domain is non-negotiable for national survival.
India’s physical geography makes maritime security an immediate and paramount strategic concern. India possesses a total coastline of 7,517 km. This extensive maritime boundary is distributed as follows:
- Mainland Coastline: 5,422 km
- Andaman and Nicobar Islands: 1,962 km
- Lakshadweep Islands: 132 km
This vast, open coastline presents complex security challenges:
- Absence of Physical Barriers: Unlike land frontiers flanked by mountain ranges or border fences, the sea boundary lacks physical barriers, making surveillance and interception demanding.
- Asymmetric Maritime Threats: Piracy, illegal landing of arms and explosives, terrorist infiltration, misuse of offshore uninhabited islands for criminal activities, human and drug trafficking, and cross-border smuggling.
- Protection of High-Value Infrastructure: The immediate coast hosts vital industrial complexes, major commercial ports, and critical national defence installations including military RADAR stations and nuclear reactors.
- Historical Lessons: India witnessed two major terrorist strikes executed via the maritime route — the 1993 Mumbai serial blasts (arms landing via the Maharashtra coast) and the 26/11 Mumbai terror attacks in 2008 (terrorist infiltration using hijacked sea vessels).
- Geopolitical Competition: Expanding Chinese naval presence in the Indian Ocean and the development of foreign naval bases, notably at Gwadar in Pakistan, creating strategic pressure along India’s maritime lifelines.
Because the overwhelming share of national trade moves through maritime corridors, goods and services enter mainland supply chains through commercial ports situated along the eastern and western seaboards. India is currently planning to build 14 Coastal Economic Zones (CEZs) to accelerate industrial growth.
At present, India’s maritime portal network comprises 12 Major Ports and 200 Minor and Intermediate Ports. The 12 major ports are spread across the western and eastern coastlines:
- Western Coast Major Ports: Mumbai, Jawaharlal Nehru Port Trust (JNPT), Mormugao, Mangaluru, Kochi.
- Eastern Coast Major Ports: Kolkata, Paradip, Vishakhapatnam, Ennore, Chennai, Tuticorin (along with intermediate hub connections).
Government Initiative — Sagarmala:
Sagarmala is a flagship initiative launched by the Government of India to modernize existing ports, build new world-class ports, and develop coastal economic zones. It also incorporates comprehensive coastal community development programs focused on skill training and livelihood generation through sustainable fisheries development and coastal tourism.
Oceans provide not only transportation routes for cargo but also hold vast untapped deposits of offshore oil, natural gas, seabed minerals, and fisheries. Globally, around 38 million people depend directly on marine fisheries for their livelihoods.
Definition: The Blue Economy is the sustainable use of ocean resources for economic growth, improved livelihoods and jobs, and ocean ecosystem health. It encompasses six interrelated activity pillars:
- Renewable Energy: Harnessing offshore wind, tidal, and wave energy.
- Fisheries: Sustainable commercial and artisanal fish harvesting without depleting ocean stock.
- Maritime Transport: Efficient merchant shipping, containerization, and eco-friendly port operations.
- Tourism: Environmentally sustainable coastal and marine recreation.
- Climate Change Mitigation: Oceans functioning as carbon sinks and regulating climate patterns.
- Waste Management: Preventing land-based industrial effluent and plastic pollution from entering sea waters.
The Indian Ocean Region (IOR) is the most strategically vital ocean in the world. More than 80% of the world's seaborne oil trade traverses through Indian Ocean choke points.
Definition of a Maritime Chokepoint:
A chokepoint refers to a point of natural congestion along two wider and important navigable passages. Maritime chokepoints are naturally narrow shipping channels experiencing heavy traffic due to their strategic locations, which can be vulnerable to naval blockades or interdiction during conflict.
- Strait of Hormuz: Transits approximately 40% of the world's seaborne oil trade.
- Strait of Malacca: Transits approximately 35% of global seaborne oil.
- Bab el-Mandab Strait: Handles approximately 8% of international seaborne oil flows.
Additional critical IOR chokepoints listed in the textbook include the Singapore Strait, Sunda Strait, Lombok Strait, Cape of Good Hope, Mozambique Channel, and Ombai and Wetar Straits. More than half of the world's armed conflicts are located in the Indian Ocean Region, exacerbated by piracy, terrorism, and big-power naval rivalries.
In India, maritime security is not the responsibility of a single agency; it operates through a unified, multi-tiered institutional matrix:
- Core Ministries: Ministry of Defence, Ministry of Home Affairs, Ministry of Fisheries, and Ministry of Shipping (with Ministry of External Affairs and Ministry of Communication & IT as key stakeholders).
- Border Forces:
- Indian Coast Guard (ICG): Established formally on 18th August 1978 by the Coast Guard Act, 1978. Responsible for the security of coastal and territorial waters, surveillance across India’s 2 million sq. km Exclusive Economic Zone (EEZ), and inter-agency coordination.
- Indian Navy: Primary maritime military force. Naval strategy is founded on securing sea lanes of communication and guaranteeing 'freedom to use the seas' for national interests while tackling diverse threat vectors.
- Border Security Force (BSF): Protects the delicate maritime-marshland frontier of the Rann of Kutch.
- Central Industrial Security Force (CISF): Entrusted with the physical security of India’s major commercial ports.
- State and Territory Coastal Agencies: State Marine Police, State Marine Home Guards (e.g., in Tamil Nadu), and State and District Coastal Security Committees.
- Intelligence & Technical Wings: NTRO, RAW, Intelligence Bureau (IB), Narcotics Control Bureau (NCB), Directorate of Revenue Intelligence (DRI), Defence Intelligence Agency (DIA), and Directorate of Naval Intelligence (DNI).
- International Compliance (ISPS Code): Developed by the International Maritime Organization (IMO) (a specialized UN agency) under the SOLAS (Safety of Life at Sea) Convention (148 signatories) post-9/11. India implemented this code in 2004, and 10 minor ports operate under its standardized security guidelines.
Maritime security involves protecting national sovereignty from threats arising from the oceans and seas. It encompasses coastal defence, securing offshore resources, maintaining freedom of commercial shipping, and protecting Sea Lanes of Communication (SLOC). It relies on seven core elements and tackles eight explicit threats detailed in the textbook.
Remember official UNCLOS boundaries: 1 Nautical Mile = 1,852 metres (1.852 km). Internal waters are part of land territory; Territorial Sea extends to 12 NM (full sovereignty); Contiguous Zone reaches 24 NM (customs/fiscal/immigration laws); EEZ covers up to 200 NM (resource rights); High Seas lie beyond 200 NM with 6 protected freedoms.
India has a total coastline of 7,517 km: Mainland (5,422 km), Andaman & Nicobar (1,962 km), and Lakshadweep (132 km). Securing this domain is critical because an estimated 95% of India’s trade is sea-based. The complete absence of physical barriers makes coastal radar stations, ports, and nuclear reactors highly vulnerable to asymmetric infiltration.
Over 80% of the world's seaborne oil trade passes through Indian Ocean chokepoints. Memorize the exact textbook shares: Strait of Hormuz handles 40%, Strait of Malacca handles 35%, and Bab el-Mandab Strait carries 8%. A chokepoint is a natural bottleneck between two wider waterways that can be easily interdicted by hostile naval forces.
The Indian Coast Guard was established on 18th August 1978 under the Coast Guard Act, 1978 to safeguard 2 million sq. km of EEZ across 5 regional commands and 12 districts. The Indian Navy secures deep SLOCs, BSF guards the marshlands of Rann of Kutch, CISF secures major ports, and the ISPS Code (enacted 2004 under IMO) governs ship-port facility security.
