The Great Nicobar Project: India's Strategic Mega-Plan in the Indian Ocean and Why It Is Controversial, Explained
India is building a port, airport, township and power plant on Great Nicobar Island near the Strait of Malacca. Supporters call it a strategic and economic game-changer; critics warn of damage to rainforests and the isolated Shompen tribe. Here is what the project is and where it stands in 2026.
At the southern tip of India, closer to Indonesia than to the Indian mainland, lies Great Nicobar Island. The government plans to turn it into a major port, airport and township, a strategic outpost near one of the world's most important sea lanes. Critics say the cost is a pristine rainforest and the future of one of India's most isolated tribes. Here is what is being built and why it is contested.
The 60-second version
- What: A transshipment port at Galathea Bay, a dual-use airport, a township and a power plant.
- Where: Great Nicobar, near the Strait of Malacca.
- Timeline: Three phases, phase one by 2035, completion by 2047.
- Cost: Estimates vary widely, from about Rs 81,000 crore to around 12.5 billion US dollars.
- Controversy: Forest clearance, wildlife, earthquake risk, and the Shompen tribe.
Why the government wants it
Trade. Most container ships moving between Europe, the Gulf and East Asia pass near Great Nicobar. Today, much of the transshipment, where cargo moves between large and small ships, happens in Colombo, Singapore and Port Klang. A deep-water port at Galathea Bay could capture some of that business for India.
Strategy. The island sits near the Strait of Malacca, a chokepoint for trade and energy flows to China and East Asia. The government has described the project as strengthening India's presence in the Andaman Sea and Southeast Asia. Reports in 2026 said India had dropped plans to extend the existing INS Baaz runway and would instead build a Rs 13,000 crore dual-use airport at Chingen, near Galathea Bay.
Why critics object
- Rainforest loss. The project requires clearing a large area of tropical forest, one of India's richest ecosystems.
- Wildlife. Galathea Bay is a nesting site for leatherback turtles, and the island is home to many endemic species.
- The Shompen. About 300 Shompen hunter-gatherers live on the island and largely avoid contact with outsiders. Rights groups warn development could expose them to disease and loss of land.
- Earthquake risk. The island lies in a highly seismic zone and was badly hit by the 2004 tsunami.
The politics
The Congress has repeatedly called for the project to be halted, saying in August 2026 that it must be stopped in the national interest, and has sought the release of a National Green Tribunal committee report. The government maintains that environmental safeguards and compensatory measures are in place and that the project is vital for national security.
By mid-2026, international reporting described land clearing under way on the island.
What to watch next
- Legal challenges before courts and the NGT.
- Port tenders and whether global shipping lines commit.
- Safeguards for the Shompen, and how they are monitored.
- Cost and timeline revisions, common for projects of this scale.
Great Nicobar is a test of how India balances strategic ambition with environmental and indigenous protection. Few projects carry stakes this high on both sides.

Frequently asked questions
›What is the Great Nicobar project?
The Great Nicobar Island Development Project is a large infrastructure plan for India's southernmost island. It includes an international container transshipment port at Galathea Bay, a dual-use civil and military airport, a new township, and a power plant. It is planned in three phases, with phase one targeted by 2035 and completion by 2047.
›Why is Great Nicobar strategically important?
Great Nicobar lies close to the Strait of Malacca, one of the world's busiest shipping chokepoints, through which a large share of trade between the Indian Ocean and East Asia passes. The government describes the project as strengthening India's presence in the Andaman Sea and Southeast Asia.
›Who are the Shompen?
The Shompen are an indigenous hunter-gatherer people of Great Nicobar, estimated by Survival International at about 300 people, who largely avoid contact with outsiders. Rights groups warn that the project could threaten their land and survival.
›How much does the Great Nicobar project cost?
Cost estimates vary across sources. Indian reporting often cites a figure of around Rs 81,000 crore, while international outlets have reported figures of up to about 12.5 billion US dollars for the full plan. In 2026, reports also said a separate dual-use airport costing about Rs 13,000 crore had been cleared.
