The Andaman and Nicobar Command Explained

The Andaman and Nicobar Command (ANC) is India’s first, and so far only, unified tri-service theatre command. Set up in 2001 with its headquarters at Port Blair, it brings the Army, Navy, Air Force and Coast Guard under a single commander for the defence and security of the Andaman and Nicobar Islands, a chain of islands that lies at the entrance to one of the busiest sea lanes on Earth.

This explainer describes why the command was created, what makes its geography so important, how it is organised, what it actually does in peace and in crisis, and why its experience is frequently cited in the national debate on creating more theatre commands. It relies on well-established, publicly known facts and avoids operational detail.

Quick Facts

Geography: Why the Islands Matter

The Andaman and Nicobar Islands form an archipelago of more than five hundred islands and islets scattered over the south-eastern Bay of Bengal, stretching in an arc of roughly 750 kilometres from north to south. They are, however, a very small part of the land area of the country. Their importance is out of all proportion to their size, because of where they lie.

A forward position in the Indian Ocean

• The islands are far closer to Southeast Asia than to the Indian mainland. The southernmost point, Indira Point on Great Nicobar, is only about 150 kilometres from the northern tip of Sumatra in Indonesia.
• The Ten Degree Channel separates the Andamans from the Nicobars, while the Six Degree Channel lies to the south of the Nicobar group. These are important shipping routes.
• The archipelago is located near the western entrance to the Strait of Malacca, through which a very large share of the world’s seaborne trade and a major part of energy shipments to East Asia pass.
• The islands give India a large maritime zone, including a substantial portion of its Exclusive Economic Zone.

In simple words, the Andaman and Nicobar chain acts as a natural unsinkable platform that allows India to watch and influence traffic on one of the world’s most important sea lanes.

Historical Background of the Islands

The islands have been home to indigenous communities for thousands of years, including the Great Andamanese, Jarawa, Onge and Sentinelese in the Andamans and the Nicobarese and Shompen in the Nicobars. The colonial period brought a penal settlement, and the Cellular Jail at Port Blair became notorious as a place where freedom fighters were sent, popularly known as Kala Pani.

Wartime and national milestones

• The islands were occupied by Japanese forces during the Second World War, from 1942 to 1945.
• Netaji Subhas Chandra Bose raised the national flag at Port Blair in December 1943, an event with high symbolic importance for the freedom movement.
• After Independence the islands became a Union Territory, administered by a Lieutenant Governor.
• In 2018 three islands, Ross, Neil and Havelock, were renamed Netaji Subhas Chandra Bose Dweep, Shaheed Dweep and Swaraj Dweep respectively.

For decades after Independence, the islands were guarded by separate service presences, without a single point of command. That arrangement was what the new command was designed to fix.

Origins: The Kargil Review and Security Reforms

The origins of the ANC lie in the reforms to the national security system after the Kargil conflict of 1999. The Kargil Review Committee, chaired by K. Subrahmanyam, examined the lapses and pointed to a need for better integration among the services and between the military and the civil government. A Group of Ministers then reviewed the entire national security apparatus and made a set of recommendations in 2001.

What the reforms recommended

• Greater integration of the Ministry of Defence and the armed forces headquarters.
• Creation of an Integrated Defence Staff to support joint planning.
• Creation of a Strategic Forces Command to manage nuclear forces.
• Creation of a unified command for the Andaman and Nicobar Islands, as a pilot for the concept of jointness.

The Andaman and Nicobar Command was therefore created on 8 October 2001. Because the islands are compact, the distances manageable and the service stakes shared, the archipelago was seen as a suitable testing ground for tri-service integration.

Organisation and Command Structure

The ANC is headed by the Commander-in-Chief, Andaman and Nicobar Command (CINCAN), a three-star officer. The position is rotated among the Army, Navy and Air Force, so that no single service owns it. The Commander-in-Chief is responsible for the operational and administrative control of the forces assigned to the command, and reports to the Chairman of the Chiefs of Staff Committee and, through the Ministry of Defence, to the political leadership.

Components

The forces are drawn from all branches of the military, and the Coast Guard has a significant presence too.

Naval establishments in the islands, such as INS Utkrosh at Port Blair, INS Baaz at Campbell Bay on Great Nicobar and INS Kohassa at Shibpur in North Andaman, along with the air base at Car Nicobar, are among the key facilities of the theatre.

Roles and Missions

The ANC has a broad mandate that goes beyond conventional warfighting. The primary responsibilities can be grouped under a few headings, which reflect the dual character of the islands as both a strategic outpost and a fragile, remote territory.

Defence of the islands

The first task is to protect the territorial integrity of the archipelago and respond to any threat to it. This includes coordinating air, land and sea assets in a joint defence plan, with the ability to reinforce quickly from the mainland.

Maritime surveillance and domain awareness

The command monitors the waters around the islands, which are on the path of heavy merchant traffic. It works with other agencies to detect illegal fishing, smuggling, piracy and other maritime crimes. Coordinated patrols are held with neighbouring countries, including Thailand and Indonesia, to improve cooperation and trust.

Engagement with partners

The islands host and support naval engagements and exercises. The multilateral naval exercise MILAN, which India started in the mid-1990s, was originally held at Port Blair. Such engagement forms part of India’s wider approach to the Indian Ocean region, sometimes described through the vision of Security and Growth for All in the Region.

Humanitarian Assistance and Disaster Relief

The islands are exposed to earthquakes, cyclones and tsunamis, and in a crisis the local administration needs help from the armed forces. The ANC has played a major role as first responder. Its defining test came on 26 December 2004, when the Indian Ocean earthquake and tsunami devastated the Nicobar group, and also affected the Car Nicobar air base, where personnel and their families suffered heavy losses.

Relief in the aftermath

• The Navy, Air Force, Army and Coast Guard worked together to rescue survivors, deliver food and medicines and restore communications.
• Naval ships and aircraft carried relief to isolated islands, and the effort was part of a wider operation by the Navy along the Indian coastline and neighbouring countries.
• The tragedy underlined the value of a joint command: pooled resources and a single commander helped to avoid confusion over responsibilities.

Since then the ANC has regularly supported cyclone relief, medical evacuation and the movement of people and supplies in remote areas, and it has worked with civil authorities on disaster preparedness.

Strategic Significance in the Indian Ocean

The Indian Ocean carries a large portion of the world’s trade and energy supplies, and several chokepoints lie around its rim. The Malacca Strait is among the narrowest and most important of them. India’s own economic security relies heavily on sea lanes, because the large majority of its trade by volume moves by sea.

• Positioned near the western approach to Malacca, the ANC allows India to keep watch on commercial and naval movement.
• The islands help extend India’s air and sea surveillance reach much farther east than from the mainland alone.
• Presence in the islands supports India’s role as a net security provider in the region.

Over the years, India has improved runways, jetties, radar coverage and maritime patrol aircraft deployments in the islands. The development projects planned for Great Nicobar, including port and infrastructure plans, are often discussed in terms of both strategic and economic value, along with environmental and tribal concerns that need careful balancing.

Challenges Faced by the Command

Operating in a remote island chain is difficult. The ANC faces constraints that mainland commands do not.

• Distance from the mainland, which makes logistics and reinforcement complex and dependent on sea and air transport.
• Limited land for infrastructure and a fragile environment with protected forests and indigenous tribal reserves.
• Weather: monsoon storms and cyclones that disrupt operations.
• A need for secure communications and resilient power and supply systems.
• Balancing development, ecology and the rights of indigenous communities with security needs.

Because the command is joint, it must also overcome different service cultures, procedures and equipment, which is one of the core challenges of integration in any military.

A Model for Future Theatre Commands

For most of its existence the ANC has been the only tri-service theatre command. This has made it a reference point in discussions about restructuring the Indian military into integrated theatre commands, in which the three services would operate under a single commander for a geographical region or a function, rather than through separate service commands.

Why the model matters

• It demonstrates that a joint structure with a rotating commander can function in practice.
• It offers insight into balancing the interests of the services in resource sharing and command appointments.
• It shows how a single commander can speed up decision-making and coordinated response in a crisis.

The creation of the post of Chief of Defence Staff in December 2019 and the Department of Military Affairs, with a mandate that includes promoting jointness and facilitating restructuring for theatre commands, renewed the debate. Proposals discussed in public have included separate theatre commands for different regions or for maritime and air defence tasks. The size and geography of the Andaman and Nicobar archipelago is however unlike the mainland, so lessons need to be applied with care.

Conclusion

The Andaman and Nicobar Command stands as an early and practical experiment in jointness in the Indian armed forces. Born from post-Kargil reform and anchored at Port Blair, it protects a strategically placed archipelago, watches over a vital sea lane and responds to natural disasters in a remote region. Its record, from the 2004 tsunami relief to everyday maritime surveillance, makes the case that unified command can work, and it will remain a key reference as India continues to reform its higher defence organisation.
