What Happened
- The Indian Navy hosted the Indian Ocean Naval Symposium (IONS) Maritime Exercise (IMEX) Tabletop Exercise (TTX) 2026 at the Maritime Warfare Centre, Southern Naval Command, Kochi on 27 March 2026.
- Delegates from 12 IONS member navies — including Bangladesh, France, Indonesia, Kenya, Maldives, Mauritius, Myanmar, Seychelles, Singapore, Sri Lanka, Tanzania, and Timor-Leste — participated alongside international officers of IOS SAGAR and Indian Navy personnel.
- The exercise focused on non-traditional maritime security challenges in the Indian Ocean Region (IOR), including enhancing shared understanding of operational approaches, examining coordination mechanisms such as information sharing and decision-making processes, and validating IONS maritime security guidelines through practical application.
- The exercise marks a significant milestone as India assumes the IONS Chairmanship for the 2026–2028 cycle — a responsibility India is taking up after a gap of sixteen years.

Indian Ocean Naval Symposium (IONS)
IONS is a voluntary, inclusive forum launched by the Indian Navy on 14 February 2008 in New Delhi to enhance maritime cooperation among the navies of the littoral states of the Indian Ocean Region. It operates on a biennial cycle, with the chairmanship rotating among member states every two years.
- Current membership: 34 participants (25 members + 9 observers), organised across four sub-regions — South Asian, West Asian, East African, and South-East Asian/Australian littorals.
- The forum addresses non-traditional threats: piracy, smuggling, terrorism, and the need for Humanitarian Assistance and Disaster Relief (HADR) coordination.
- India originally initiated IONS in 2008 and is now re-assuming chairmanship for 2026–2028, signalling a strategic re-engagement with the Indian Ocean multilateral architecture.
Connection to this news: IMEX TTX 2026 is the flagship exercise held under India's current IONS Chairmanship; it tests the practical frameworks IONS has developed over 18 years for cooperative maritime security.
Non-Traditional Security Threats in the Indian Ocean Region
Non-traditional security threats differ from conventional state-to-state military conflicts. In the maritime domain, they include piracy, narcotics trafficking, illegal, unreported and unregulated (IUU) fishing, human trafficking, and environmental crimes. The Indian Ocean — through which more than 80% of the world's seaborne oil trade passes — is especially vulnerable given the vast distances, porous coastlines, and the presence of weak-state environments.
- The IOR is home to some of the world's busiest sea lanes, including routes through the Strait of Hormuz, Strait of Malacca, and around the Cape of Good Hope.
- HADR cooperation is a core IONS mandate, relevant given the IOR's exposure to cyclones, tsunamis, and other natural disasters.
- Information sharing is the primary tool for counter-piracy and maritime domain awareness, with India's Information Fusion Centre – Indian Ocean Region (IFC-IOR) at Gurugram acting as the regional hub.
Connection to this news: IMEX TTX 2026 specifically tested coordination mechanisms and information-sharing protocols among IOR navies, directly strengthening the region's collective non-traditional security architecture.
India's Maritime Security Strategy and SAGAR
India's maritime security doctrine is anchored in the vision of SAGAR — Security and Growth for All in the Region — articulated by Prime Minister Narendra Modi in Mauritius in 2015. Under SAGAR, India positions itself as a net security provider in the IOR, offering capacity building, maritime domain awareness sharing, and coordinated response to common threats. IOS SAGAR is the operational maritime initiative that operationalises this vision.
- India's 2015 Maritime Security Strategy identifies the IOR as India's primary strategic zone of interest, extending from the Persian Gulf to the Strait of Malacca.
- The Indian Navy operates a network of coastal radar chains, offshore patrol vessels, and maritime patrol aircraft in coordination with smaller IOR states.
- India has bilateral maritime security agreements or white-shipping agreements with several IOR states, enabling real-time sharing of Automatic Identification System (AIS) data.
Connection to this news: International officers of IOS SAGAR participated alongside IONS member navies at IMEX TTX 2026, underscoring the institutional convergence of India's bilateral maritime outreach with its multilateral engagement under IONS.
Tabletop Exercises (TTX) in Defence Training
A Tabletop Exercise is a structured discussion-based simulation in which participants walk through a hypothetical scenario to test plans, procedures, and coordination mechanisms — without deploying actual assets. TTXs are widely used for disaster response, counter-terrorism, and maritime security planning because they allow navies to identify gaps and mismatches in protocols at low cost and without operational risk.
- TTXs complement field exercises (FTX) and are particularly valuable for multilateral settings where logistics and language barriers make full deployments difficult to coordinate.
- They are used to validate Standard Operating Procedures (SOPs) and test command-and-control communication across different national systems.
- The IMEX series specifically stress-tests the IONS Maritime Security Guidelines, which are the common frameworks all member navies are expected to follow during joint operations.
Connection to this news: IMEX TTX 2026 used this format to bring together 12 nations in a cost-effective simulation that builds real operational readiness for IOR contingencies.
