2-Minute Revision

India's coastal security protects 7,516 kilometers of coastline through a comprehensive multi-layered architecture developed post-26/11 Mumbai attacks. The Coastal Security Scheme (2005) provides the policy framework with over ₹3,000 crores allocated across multiple phases for infrastructure development, technology deployment, and capacity building.

The four-tier institutional structure assigns specific roles: Indian Navy handles high seas to territorial waters security with overall maritime defense responsibility; Indian Coast Guard serves as the principal maritime law enforcement agency with 150+ vessels and 60+ aircraft; state marine police forces manage near-shore security and fishing community interface; port authorities ensure facility security under ISPS Code compliance.

Technological infrastructure includes the Coastal Surveillance Network with 80+ radar stations providing overlapping coverage, Automatic Identification System mandatory for vessels above 20 meters, and biometric registration of 400,000+ fishermen with GPS-enabled devices.

Major challenges include vast coastline coverage, coordination among multiple agencies, dual-use fishing vessels, and emerging threats like maritime terrorism, cyber attacks, and drone warfare. Regular exercises like Sea Vigil (annual) and Sagar Kavach (biennial) test coordination and preparedness.

Recent developments include the National Maritime Domain Awareness project (₹2,000 crores) for integrated surveillance and the Information Fusion Centre - Indian Ocean Region facilitating cooperation with 24 partner nations.

The framework emphasizes community participation, international cooperation, and technology integration while balancing security imperatives with livelihood protection and constitutional rights.

5-Minute Revision

India's coastal security architecture represents a comprehensive transformation from basic patrolling to sophisticated maritime domain awareness following the 26/11 Mumbai attacks. The 7,516-kilometer coastline across nine states and four union territories, with 1,382 islands and over 2 million square kilometers of exclusive economic zone, requires multi-dimensional security coverage.

The Coastal Security Scheme, launched in 2005 and significantly strengthened post-2008, operates through multiple phases with total allocation exceeding ₹3,000 crores. Phase-I focused on basic infrastructure, Phase-II emphasized technological upgrades, and the current phase prioritizes integration and community participation.

The four-tier institutional structure ensures comprehensive coverage: the Indian Navy maintains overall maritime security from high seas through territorial waters via Western and Eastern Naval Commands with specialized MARCOS units; the Indian Coast Guard, established under the 1978 Act, serves as the principal maritime law enforcement agency with five regional headquarters, 150+ vessels, and 60+ aircraft handling search-rescue, anti-smuggling, and fisheries protection; state marine police forces operate patrol boats and maintain fishing community interface; port authorities implement ISPS Code security measures at major and minor ports.

Technological infrastructure centers on the Coastal Surveillance Network with over 80 radar stations providing 25-50 nautical mile coverage, Automatic Identification System requiring transponders on vessels above 20 meters, electro-optical sensors for visual confirmation, and satellite-based surveillance for remote areas.

The biometric registration system covers 400,000+ fishermen with identity cards and GPS devices, while color-coding schemes distinguish vessel types. Joint Operations Centers provide 24/7 coordination with the Information Management and Analysis Centre serving as the national hub.

Major challenges include resource constraints for vast coastline coverage, coordination complexities among multiple agencies, dual-use fishing vessel identification, emerging threats like maritime terrorism and cyber attacks, and climate change impacts on infrastructure.

International cooperation through bilateral agreements, IFC-IOR with 24 partner nations, and Quad maritime security initiatives enhances regional security. Regular exercises including Sea Vigil (world's largest coastal security exercise) and Sagar Kavach test multi-agency coordination and community participation.

Recent developments include the National Maritime Domain Awareness project integrating AI and satellite surveillance, enhanced cybersecurity measures, and climate-resilient infrastructure planning. The framework balances security imperatives with livelihood protection, environmental conservation, and international maritime law compliance, representing India's evolution as a net security provider in the Indo-Pacific region.
