🗞️ Why in News The second edition of Indian Ocean Ship (IOS) SAGAR commenced on March 16, 2026, with the Indian Navy leading a joint maritime training programme with personnel from 16 nations of the Indian Ocean Naval Symposium (IONS), beginning at Kochi and transitioning to a sea deployment on an Indian Naval Ship. India assumed the IONS chair in February 2026.
IOS SAGAR — Programme Overview
IOS SAGAR stands for Indian Ocean Ship — Security and Growth for All in the Region. It is a unique Indian Navy-led initiative that enables naval personnel from friendly foreign countries to train and operate together aboard an Indian Naval Ship.
What makes it unique: Unlike bilateral naval exercises (which involve ships from two countries operating together), IOS SAGAR is a multilateral capacity-building initiative where foreign naval officers and sailors are actually embedded within the crew of an Indian warship — training, sailing, and conducting real operations alongside Indian sailors.
Programme structure:
- Shore-based phase (Kochi): 2–3 weeks of intensive professional training at Indian Naval establishments in Kochi — covering seamanship, navigation, maritime law, anti-piracy protocols, damage control, and naval doctrine
- Sea deployment phase: Foreign personnel embark on an Indian Naval Ship for active maritime patrol, exercising real-world tasks — communication, watch-keeping, damage control, gunnery, and anti-submarine warfare
Participating nations (second edition, 2026): 16 IONS nations — members of the Indian Ocean Naval Symposium drawn from South Asia, Southeast Asia, East Africa, Gulf, and Australia regions.
The SAGAR Doctrine — India’s Maritime Vision
SAGAR (Security and Growth for All in the Region) was articulated by Prime Minister Narendra Modi during his visit to Mauritius on March 12, 2015 — establishing India’s strategic framework for the Indian Ocean Region (IOR).
Five pillars of SAGAR:
- Security: Safeguarding the maritime domain from piracy, terrorism, natural disasters
- Growth: Sustainable, inclusive development of Indian Ocean island and littoral states
- Rule-based order: Respecting maritime law (UNCLOS), freedom of navigation, and sovereignty
- Blue economy: Developing ocean resources (fisheries, seabed minerals, offshore energy) sustainably
- Digital and infrastructure connectivity: Cable networks, port infrastructure, satellite links across the IOR
MAHASAGAR framework (2025): India upgraded the SAGAR vision to MAHASAGAR — Mutual and Holistic Advancement for Security and Growth Across Regions — announced by PM Modi during his visit to Mauritius in March 2025. MAHASAGAR extends the framework from the Indian Ocean to broader maritime engagement, with Africa as a central pillar. Under MAHASAGAR, India launched two key initiatives: the AIKEYME (Africa-India Key Maritime Engagement) naval exercise and the IOS SAGAR mission.
IONS — Indian Ocean Naval Symposium
Indian Ocean Naval Symposium (IONS) is India’s primary multilateral naval platform in the Indian Ocean Region.
Key facts:
- Founded: 2008; proposed by the Indian Navy
- Chair: Rotates among member navies (2-year tenure)
- India assumed chair: February 2026 (from the Royal Thai Navy; 9th IONS Conclave of Chiefs at Visakhapatnam on 20 Feb 2026; tenure 2026–28; India returns after 16 years)
- Membership: 25 member navies and 9 observers from the Indian Ocean littoral (coastal) states — South Asia, Southeast Asia, Persian Gulf, Red Sea, East Africa, South Africa, Australia
- Purpose: Information sharing, maritime security coordination, disaster response, combating piracy and trafficking, capacity building
- Distinction from QUAD: IONS includes a much wider membership including non-Western nations; QUAD (India, US, Japan, Australia) is a strategic security arrangement specifically countering China’s influence
IONS Working Groups:
- Maritime Security (piracy, terrorism, trafficking)
- Humanitarian Assistance and Disaster Relief (HADR)
- Information Security and Interoperability (IS&I) — enhances real-time information exchange and joint maritime operations
India’s Naval Expansion — Strategic Context
India’s growing naval footprint:
The Indian Navy has been undergoing a significant capability expansion:
| Capability | Status (2026) |
|---|---|
| Aircraft Carriers | 2: INS Vikramaditya + INS Vikrant (India’s first indigenous carrier, commissioned 2022) |
| Nuclear Submarines | 2 SSBNs operational (INS Arihant, commissioned 2016; INS Arighaat, commissioned Aug 2024); INS Aridhaman (S4) completed deep-sea trials, set for induction April–May 2026 |
| P-75I (SSK) | 6 next-gen diesel-electric conventional subs with AIP; Mazagon Dock + TKMS (Germany); IGA signed Jan 2026; first delivery expected ~2032 |
| P-8I Poseidon | Maritime patrol aircraft from Boeing; anti-submarine warfare |
| Overseas facilities | Seychelles (Assumption Island); Mauritius; Sri Lanka (Trincomalee discussions); Oman (Duqm) |
Why the Indian Ocean matters:
- 80% of world’s oil trade passes through the Indian Ocean
- 50% of all containerised cargo uses IOR shipping lanes
- Critical chokepoints: Strait of Hormuz, Strait of Malacca, Bab-el-Mandeb, Mozambique Channel
- China’s String of Pearls — strategic infrastructure (ports, bases) in Gwadar (Pakistan), Hambantota (Sri Lanka), Kyaukpyu (Myanmar), Djibouti — encircles India
India’s counter-strategy — SAGAR + IOS SAGAR:
- Capacity building: IOS SAGAR and IONS build partner navies’ capabilities, creating an informal India-led maritime security network
- Port access agreements: ACSA-type agreements with France, US, Japan, Australia for mutual logistics support in IOR ports
- QUAD maritime surveillance: India participates in QUAD’s Maritime Domain Awareness initiative
