What Happened
- INS Sunayna set sail from Mumbai on April 2, 2026 as the Indian Ocean Ship (IOS) SAGAR, carrying naval personnel from India and sixteen friendly foreign countries for the second edition of this maritime cooperation initiative.
- The sea phase runs from April 2 to May 20, 2026, covering the South-Eastern Indian Ocean Region, with port calls at Colombo (Sri Lanka), Phuket (Thailand), Jakarta (Indonesia), Singapore, Chittagong (Bangladesh), Yangon (Myanmar), and Male (Maldives), concluding at Kochi.
- The Harbour Phase ran from March 16-29, 2026, with participating nations' personnel completing joint training exercises before the ship's departure.
- India holds the chairmanship of the Indian Ocean Naval Symposium (IONS) this year; IOS SAGAR is positioned as a flagship initiative under that leadership.
- The launch of IOS SAGAR 2 comes against the backdrop of heightened West Asia tensions and ongoing geopolitical competition in the Indian Ocean Region (IOR), underscoring India's role as a "net security provider."
Static Topic Bridges
SAGAR Doctrine — Security and Growth for All in the Region
SAGAR (Security and Growth for All in the Region) is India's strategic maritime framework for the Indian Ocean Region, first articulated by Prime Minister Narendra Modi in Mauritius on March 12, 2015. It represents India's vision of itself as a responsible maritime power that leads through cooperation, capacity-building, and multilateral engagement rather than coercion. SAGAR underpins most of India's Indian Ocean maritime diplomacy and naval engagement activities.
- Five pillars of SAGAR: maritime security of India's mainland and island territories; deepening economic and security cooperation with IOR neighbours; collective action and responsibility-sharing; sustainable development through blue economy; and strengthening maritime domain awareness.
- SAGAR directly counters China's Maritime Silk Road (Belt and Road Initiative) by offering an alternative connectivity and security framework for IOR states.
- Implementation tools: Integrated Coastal Surveillance System (ICSS) extended to Maldives, Seychelles, Mauritius; humanitarian assistance and disaster relief (HADR) operations; Hydrographic survey assistance; white shipping information-sharing agreements.
- In March 2025, India upgraded SAGAR to MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions) — extending the vision to the broader Global South.
Connection to this news: IOS SAGAR is literally named after this doctrine — it is the most direct operational manifestation of the SAGAR framework, translating the doctrine's cooperation principles into a real joint maritime deployment with 16 IOR nations.
Indian Ocean Naval Symposium (IONS) and India's Maritime Leadership
The Indian Ocean Naval Symposium (IONS) is a voluntary initiative of navies of the littoral states of the Indian Ocean Region, established in 2008 under India's initiative. It provides a cooperative forum for maritime security cooperation, information sharing, and capacity building. As the current IONS chair, India's sponsorship of IOS SAGAR 2 demonstrates chairmanship being used actively to shape regional maritime architecture.
- IONS was established in New Delhi in February 2008 under the theme "Charting a Course for Regional Maritime Security."
- Membership spans 24 littoral IOR states; observers include the US, UK, Japan, and others.
- IONS operates through a rotating chairmanship; India's current chairmanship (2025-27) is its second term.
- Concurrent maritime initiatives: QUAD (India, US, Japan, Australia) focuses on Indo-Pacific security; IORA (Indian Ocean Rim Association) addresses economic cooperation.
- India's Information Fusion Centre — Indian Ocean Region (IFC-IOR) at Gurugram was set up in 2018 as a real-time maritime domain awareness hub.
Connection to this news: Hosting 16 nations on a single Indian naval vessel for a month-long deployment is a powerful exercise in soft maritime power — demonstrating India's logistical capability, professional credibility, and diplomatic convening power in the IOR.
Freedom of Navigation and Indian Ocean Geopolitics
The Indian Ocean carries approximately 80% of the world's seaborne oil trade and over 30% of global cargo trade, making its security critical for India (which imports ~85% of its oil through IOR sea lanes). China's growing presence — through the "String of Pearls" ports in Pakistan (Gwadar), Sri Lanka (Hambantota), Myanmar (Kyaukpyu), and Djibouti — has intensified India's resolve to strengthen maritime partnerships with smaller IOR states.
- India's exclusive economic zone (EEZ): 2.37 million sq km (7th largest in the world); with continental shelf, India's maritime zone exceeds 7 million sq km.
- India's island territories — Andaman & Nicobar Islands (near Malacca Strait) and Lakshadweep — are strategically located chokepoints.
- UNCLOS (1982): Governs freedom of navigation, innocent passage, EEZ rights; India is a signatory but China disputes its application.
- Indian Navy's Mission Based Deployment (MBD): Round-the-clock presence across six maritime zones to ensure IOR surveillance.
- West Asia conflict relevance: Houthi attacks on Red Sea shipping (2024-26) have diverted trade through the Cape of Good Hope, increasing the relative importance of IOR maritime security.
Connection to this news: IOS SAGAR 2's port calls across South and Southeast Asia — from Sri Lanka to Maldives to Bangladesh to Myanmar — trace the geographic arc where China's "String of Pearls" and India's partnerships converge. Each port call is a strategic statement about India's preferred maritime order.
