Indian Coast Guard Expands Coastal Radar Network: Next-Gen Offshore Patrol Vessels Commissioned for EEZ Security
In an aggressive push to fortify maritime territorial integrity, combat cross-border narcotics trafficking, and ensure absolute safety across India’s 2.01 million square kilometer Exclusive Economic Zone (EEZ), the Indian Coast Guard (ICG) has officially commissioned the latest batch of indigenously constructed Offshore Patrol Vessels (OPVs) while completing the operational integration of Phase-II of the Coastal Surveillance Network (CSN).
The commissioning ceremony—presided over by senior defense officials and naval commanders at the naval docks in Chennai—marks a critical advancement in India’s maritime domain awareness.
Equipped with advanced integrated bridge systems, high-power long-range electro-optic infrared sensors, and helicopter landing decks capable of operating indigenous ALH Dhruv Mk-III maritime helicopters, these state-of-the-art patrol ships provide round-the-clock rapid response capabilities across the critical sea lanes of communication (SLOCs) traversing the Arabian Sea, the Bay of Bengal, and the Andaman & Nicobar archipelagos.
1. Technological Architecture of the Coastal Surveillance Network (CSN Phase-II)
The expanded Coastal Surveillance Network links over 84 automated coastal radar stations and mobile surveillance vehicles into unified, real-time command control centers located in Mumbai, Chennai, Gandhinagar, Kolkata, and Port Blair:

Key Surveillance Capabilities:
- Unbroken Radar Horizon: Eliminates historic blind spots along remote estuarine deltas in the Rann of Kutch, the Sundarbans, and the Palk Strait.
- Satellite AIS Integration: Tracks over 10,000 commercial merchant vessels, oil supertankers, and container carriers transiting the Indian Ocean daily in real-time.
- Biometric Transponder Tracking for Small Craft: Mandating satellite-linked emergency transponders on over 300,000 artisanal and mechanized fishing boats to distinguish genuine fishermen from illicit intruders.
2. Technical Specifications of Next-Gen Offshore Patrol Vessels
Constructed indigenously under the Aatmanirbhar Bharat defense manufacturing framework by leading Indian shipyards (Goa Shipyard Limited and L&T Shipbuilding):
| Vessel Specification | Operational Capability / Benchmark |
|---|---|
| Overall Length & Displacement | 105 Meters |
| Maximum Speed & Endurance | Top Speed: 26+ Knots |
| Main Armament | 30mm CRN-91 Naval Gun integrated with Fire Control Radar |
| Aviation Facility | Helideck and hangar for 1 Twin-Engine ALH Helicopter + Unmanned Aerial Systems (UAS) |
| Pollution Control Response | Side-sweeping oil recovery booms and ocean dispersant spray systems |
3. Combating Transnational Maritime Crime and Humanitarian SAR
Over the past twelve months, the Indian Coast Guard’s enhanced surveillance posture has yielded historic operational results:
- Narcotics Seizures: Intercepted and seized over ₹4,500 Crore worth of high-purity methamphetamine and heroin being smuggled via illicit international dhow routes across the Arabian Sea.
- Search and Rescue (SAR) Operations: Rescued over 450 distressed fishermen and merchant sailors during severe cyclonic disturbances in the Bay of Bengal, maintaining a 100% SAR success rate within the Indian Search and Rescue Region (ISRR).
- Marine Ecological Defense: Deployed emergency containment vessels during localized tanker collisions, preventing devastating coastal environmental oil spills.
4. Conclusion: A Pillar of Regional Stability in the Indian Ocean
As geopolitical contestation across the Indo-Pacific intensifies, the Indian Coast Guard continues to serve as an indispensable, vigilant sentinel of India’s sovereign seas.
Through indigenous shipbuilding, cutting-edge radar networks, and disciplined maritime vigilance, the force ensures that India’s vast maritime borders remain a secure corridor of global commerce, sustainable blue economy, and national peace.
