Tri-Services Andaman and Nicobar Command
The Tri-Services Andaman and Nicobar Command is an integrated theatre command of India headquartered at Port Blair on the Andaman Islands, responsible for tri-service operations across the Andaman Sea and portions of the Bay of Bengal. Formed to unify elements of the Indian Navy, Indian Army, and Indian Air Force, it sits adjacent to vital sea lanes like the Strait of Malacca and interfaces with regional actors such as Indonesia, Myanmar, Thailand, and Singapore. The command shapes India’s strategic posture vis-à-vis multinational frameworks including the Indian Ocean Rim Association, Association of Southeast Asian Nations, and bilateral ties with United States, Japan, and Australia.
The concept originated after the Kargil War and strategic reviews in the late 1990s, influenced by lessons from the 1999 Kandahar crisis and naval deployments during the 1998 Indian nuclear tests. Formal establishment in 2001 followed policy deliberations involving the National Security Council and inputs from chiefs of the Indian Navy, Indian Army, and Indian Air Force. Early years saw infrastructure projects drawn from the Ministry of Defence budget and engagement with foreign navies during port calls by USS Abraham Lincoln (CVN-72), HMS Queen Elizabeth, and French Navy vessels. Expansion phases reflected shifts after events such as the 2004 Indian Ocean earthquake and tsunami and enhanced collaboration under the Quadrilateral Security Dialogue framework.
The command is led by a three-star officer titled the Commander-in-Chief, drawn from rotation among the Indian Navy, Indian Army, and Indian Air Force. Subordinate structures include a maritime component primarily from the Eastern Naval Command, a land component from the Andaman and Nicobar Regiment and elements of the Indian Army Southern Command, and an air component integrating units from the Andaman and Nicobar Islands Air Headquarters and detachments employing platforms like the Sukhoi Su-30MKI and C-130J Super Hercules. Support formations coordinate with agencies such as the Border Roads Organisation, Directorate of Naval Design, and Integrated Defence Staff for logistics, intelligence sharing with Research and Analysis Wing, and liaison with the Ministry of Home Affairs for civil-military cooperation.
Primary responsibilities include sea control in the eastern Indian Ocean approaches, protection of commercial sea lanes including traffic transiting the Strait of Malacca, maritime domain awareness leveraging assets like P-8 Poseidon and MQ-9 Reaper UAVs, humanitarian assistance and disaster relief prompted by events akin to the 2004 tsunami, and forward basing for power projection in contingency scenarios such as disputes over exclusive economic zones with Myanmar or Indonesia. It also contributes to counter-piracy initiatives coordinated with task forces like Combined Task Force 151 and participates in maritime security dialogues with Indian Ocean Rim Association members.
Naval assets include frigates drawn from classes such as Shivalik-class frigate and Talwar-class frigate, offshore patrol vessels, fast attack craft, and submarine support facilities compatible with boats like the Kalvari-class submarine. Air assets comprise helicopters such as the HAL Dhruv, maritime patrol aircraft including the P-8I Neptune, and transport platforms like the C-17 Globemaster III. Army elements field infantry, artillery, and coastal defence units drawn from formations including the Andaman and Nicobar Regiment and engineering units from the Assam Regiment for infrastructure and fortification tasks. Intelligence and surveillance are augmented by satellites from Indian Space Research Organisation and signals units linked to the Defence Research and Development Organisation sensor suites.
The command has conducted disaster relief operations after events like the 2004 Indian Ocean earthquake and tsunami and coordinated evacuations comparable to Operation Raahat. Regular multinational and bilateral exercises include participation with Singapore Armed Forces in SIMBEX, with Thailand and Indonesia in trilateral drills, and with United States units under exercises such as Malabar and Cope India. Independent operations emphasize maritime interdiction, anti-submarine warfare, and amphibious readiness validated in exercises featuring INS Arihant-class deployments and coordinated air-naval drills with Indian Naval Academy-trained officers.
Headquarters at Port Blair is supported by airfields like Veer Savarkar International Airport and naval facilities at Campbell Bay and Car Nicobar Islands. Development projects have included runway extensions, pier construction, and radar installations linked to the Integrated Space Cell and coastal surveillance network nodes interoperable with systems from the Indian Coast Guard. Logistics corridors utilize ports such as Chennai Port and Visakhapatnam for sustainment, while planned expansions reference lessons from strategic bases like Diego Garcia and forward logistics concepts in the Indo-Pacific.
Sited astride critical chokepoints, the command influences freedom of navigation in waters connecting the South China Sea to the Indian Ocean, shaping regional balances involving People's Republic of China naval activities and PLAN expeditionary trends. It serves as a hub for cooperation under the Quad and bilateral security arrangements with France for Indian Ocean presence and aligns with initiatives under the Blue Economy and maritime domain awareness partnerships. The command’s posture affects energy routes carrying crude via chokepoints used by Japan and South Korea, and it factors in contingency planning related to scenarios involving ASEAN maritime disputes and cooperative search and rescue governed by the International Maritime Organization conventions.
