Great Nicobar Island Project: India’s Bold Move to Secure the Indian Ocean

Sep 9, 2025

—

The Great Nicobar Island Project is one of the most ambitious infrastructure plans undertaken by India. Located at the southern tip of the Andaman & Nicobar Islands, this project is not just about development—it is about securing India’s strategic dominance in the Indian Ocean Region (IOR) while fostering growth and connectivity.

By sealing Nicobar with modern infrastructure, India aims to transform this remote island into a strategic, economic, and security hub, ensuring national security and opening doors to global trade.

Key Features of the Project

Component	Description
International Transshipment Port (ICTT)	A world-class cargo terminal at Galathea Bay, enabling India to compete with Singapore and Colombo as a maritime hub.
International Airport	A greenfield airport serving both civilian and defense needs, with a passenger capacity of 4,000 per hour.
Greenfield Township	A planned modern township to support workers, residents, and defense establishments.
Power Infrastructure	A mix of solar and natural gas power plants for sustainable energy supply.
Tourism Boost	Plans for eco-tourism and luxury resorts to attract global travelers while maintaining controlled access.

Estimated Investment: ₹72,000–₹75,000 crore
Project Duration: Spread across 30 years in multiple phases
Total Area: ~16,600 hectares, including forest and biosphere land

Why India Wants to “Seal” Nicobar

The phrase “sealing Nicobar” reflects India’s vision of using the island as a fortified economic and security zone.

Strategic Importance

Great Nicobar lies close to the Malacca Strait, through which over 40% of global trade passes.
Securing Nicobar strengthens India’s position against rising regional challenges, including China’s influence in the Indian Ocean.
The dual-use airport and naval presence will make Nicobar a defense shield in the Bay of Bengal.

Economic Growth

With the international port, India can reduce dependence on foreign hubs for cargo movement.
The township and airport will create thousands of jobs and boost trade.
Tourism, shipping, and logistics will add new revenue streams.

National Security

India aims to prevent unchecked external influence by sealing the region with infrastructure and defense installations.
A well-developed Nicobar ensures that India maintains exclusive control over one of the world’s most crucial sea lanes.

Environmental and Tribal Concerns

While the project promises growth, it also raises critical issues.

Concern	Details
Deforestation	Nearly 850,000 trees to be cut, including mangroves.
Biodiversity	Threat to habitats of leatherback turtles, saltwater crocodiles, Nicobar megapode, and coral reefs.
Tribal Rights	Risk of cultural extinction for the Shompen and Nicobarese tribes due to displacement and exposure.
Population Surge	Current population of 8,000 may increase to 400,000, straining resources.

Despite these concerns, India has cleared the project with promises of coral translocation, compensatory afforestation, and controlled development to balance growth with sustainability.

India’s Balancing Act

The Great Nicobar Project highlights the tension between development and preservation. On one hand, it is a gateway to:

Secure maritime trade routes
Strengthen defense positioning
Boost economic growth

On the other, it poses challenges to the island’s fragile ecosystem and indigenous communities.

India’s long-term success will depend on ensuring that development is inclusive, sustainable, and respectful of natural and human heritage.

Conclusion

The Great Nicobar Island Development Project is not just another infrastructure project—it is a statement of intent. By sealing Nicobar with ports, airports, and defense presence, India is sending a clear message: it is ready to protect its interests, secure its maritime borders, and embrace future growth.

If executed responsibly, this project can turn Great Nicobar into a symbol of India’s rise as a global maritime power—balancing progress with preservation.
