Indian Coast Guard

The Indian Coast Guard (ICG) is the fourth armed force of the Indian Union, a maritime law-enforcement and search-and-rescue service raised under the Coast Guard Act, 1978 (Act No. 30 of 1978), which received presidential assent on 18 August 1978. The service was formally constituted on 1 February 1977 as an interim measure under the Ministry of Defence, before the statute gave it permanent legal footing. Its creation followed the recommendations of the Rustamji Committee of 1974, which examined the gaps in policing India's then-newly enlarged maritime zones. The legal foundation rests jointly on the Coast Guard Act and the Maritime Zones of India Act, 1976, together with the Territorial Waters, Continental Shelf, Exclusive Economic Zone and Other Maritime Zones Act, 1976, which delimited the 12-nautical-mile territorial sea and the 200-nautical-mile Exclusive Economic Zone (EEZ) that the ICG is charged with protecting. India's accession to the United Nations Convention on the Law of the Sea (UNCLOS), ratified on 29 June 1995, anchors these zones in international law.

Operationally, the ICG functions through a tiered command structure. The Director-General Indian Coast Guard (DGICG), an officer of flag rank headquartered at New Delhi, exercises overall command and reports to the Ministry of Defence. Below the headquarters, the maritime area is divided into Coast Guard Regions—Western, Eastern, North-East, Andaman & Nicobar, and North-West—each under a Commander Coast Guard Region of flag or commodore rank. Regions are further subdivided into Districts headed by District Commanders, beneath which lie individual Coast Guard Stations and Air Enclaves. Tasking flows from the Maritime Rescue Coordination Centres (MRCCs) and sub-centres that coordinate distress response. Section 14 of the Coast Guard Act enumerates the statutory duties: protection of maritime and other national interests in the maritime zones, enforcement of maritime laws, safety of life and property at sea, and preservation of the marine environment.

The service's enforcement powers are substantial. Under Sections 105 to 110 of the Customs Act, 1962, Coast Guard officers exercise powers of search, seizure, and arrest against smuggling and contraband at sea. Personnel are deputed authority to enforce fisheries regulations, prevent poaching by foreign vessels, interdict narcotics under the Narcotic Drugs and Psychotropic Substances Act, 1985, and respond to marine pollution under the Merchant Shipping Act, 1958. The ICG operates the National Oil Spill Disaster Contingency Plan (NOS-DCP), for which it is the central coordinating agency. Its fleet comprises offshore patrol vessels, fast patrol vessels, interceptor boats, hovercraft, and a fixed- and rotary-wing aviation arm flying Dornier-228 surveillance aircraft and advanced light helicopters.

In contemporary practice, the ICG's profile expanded sharply after the 26 November 2008 Mumbai attacks, when terrorists infiltrated by sea exposed coastal-security gaps. The subsequent reorganisation designated the Indian Navy as the authority for overall maritime security and the ICG as the lead for coastal security within territorial waters and the contiguous zone, integrating state marine police into a three-tier framework. The ICG has since commissioned indigenously built vessels from Goa Shipyard Limited and Larsen & Toubro, and in 2023–2024 New Delhi advanced acquisitions of additional offshore patrol vessels and Dornier aircraft. The service routinely conducts joint exercises such as the Japan–India Coast Guard cooperation under the 2000 Memorandum and the Sahyog–series drills, and it administers the regional Heads of Asian Coast Guard Agencies Meeting (HACGAM) engagements.

The Indian Coast Guard must be distinguished from the Indian Navy, which is a war-fighting service under the Navy Act, 1957, whose primary mandate is the projection of combat power and the defence of sea lines of communication; the ICG is a constabulary force whose peacetime role is law enforcement, though Section 14(2) permits its placement under naval operational control during war or emergency. It is equally distinct from the marine police of coastal states, which operate only within shallow coastal waters under state jurisdiction, and from the Sashastra Seema Bal or Border Security Force, which are land-border forces. Unlike Customs or the Directorate of Revenue Intelligence, the ICG is an armed uniformed service organised on military lines, yet its powers derive from civil statutes rather than martial command.

Several edge cases and controversies shape the service's current posture. Jurisdictional friction occasionally arises between the ICG and the Navy over command of coastal-security operations, partly addressed by the National Committee for Strengthening Maritime and Coastal Security. The 2014 grounding and burning of a vessel off Porbandar—where the ICG was alleged to have intercepted a suspected Pakistani boat on 31 December 2014—generated debate over rules of engagement and proportionate force at sea. Capacity shortfalls in vessel numbers relative to the vast 7,500-kilometre coastline and the sprawling island territories remain a persistent concern. The integration of the National Command Control Communication and Intelligence Network (NC3I) and the coastal radar chain has improved domain awareness but exposed gaps in maintenance and inter-agency data sharing.

For the working practitioner, the Indian Coast Guard is the principal instrument of India's day-to-day maritime governance below the threshold of armed conflict—the agency that desk officers, fisheries negotiators, and counter-narcotics analysts engage when sea-based enforcement is required. Understanding its statutory limits under the Coast Guard Act, its coordinating role in oil-spill and search-and-rescue response, and its layered relationship with the Navy and state police is essential for anyone assessing India's coastal-security architecture, EEZ enforcement, or Indian Ocean diplomacy.
