PIB TrackerINS Sunayna sails as IOS SAGAR with 16 nations
An Indian Navy patrol vessel deploys from Mumbai with crews from 16 friendly foreign countries — the floating expression of Vision MAHASAGAR.
What happened
- On 2 April 2026, the offshore patrol vessel INS Sunayna set sail from Mumbai re-designated for the mission as Indian Ocean Ship (IOS) SAGAR.
- She carries naval personnel from India and 16 Friendly Foreign Countries (FFCs) on a single mixed crew — not a fleet of 16 ships, but one Indian platform jointly manned.
- The deployment was flagged off by Raksha Rajya Mantri (Minister of State for Defence) Sanjay Seth, in the presence of the Chief of the Naval Staff, Admiral Dinesh K. Tripathi.
- It is the operational expression of Vision MAHASAGAR — Mutual and Holistic Advancement for Security and Growth Across Regions — and reflects the Neighbourhood First policy.
- The mission runs in two parts: a Harbour Phase (16–29 March 2026) for joint pre-sail training, followed by a Sea Phase (2 April–20 May 2026) across the South-Eastern Indian Ocean.
- Planned port calls: Colombo, Phuket, Jakarta, Singapore, Chittagong, Yangon and Male, with the voyage concluding at Kochi.
Background & context
This is not a standalone event but the latest expression of a maritime doctrine India has been building for over a decade. In 2015, during a visit to Mauritius, the Prime Minister articulated SAGAR — Security and Growth for All in the Region — India's framing of itself as a net security provider and first responder in the Indian Ocean Region (IOR). SAGAR positioned the Indian Navy as a partner that builds the maritime capacity of smaller littoral states rather than dominating them. The IOS SAGAR mission borrows that acronym deliberately: a single Indian ship, jointly crewed, sailing the region as a working demonstration of "security and growth for all."
In early 2025, the doctrine was widened and re-badged as Vision MAHASAGAR — Mutual and Holistic Advancement for Security and Growth Across Regions. The shift in the name signals an ambition that now reaches beyond the immediate IOR neighbourhood to the wider Global South and the broader Indo-Pacific, while keeping the same cooperative, capacity-building DNA. IOS SAGAR is described in the release as the operational expression of that vision — the policy translated into a deck, a crew and a voyage. It is paired conceptually with the Neighbourhood First policy, which prioritises India's immediate maritime and continental neighbours in foreign and security cooperation.
The first IOS SAGAR deployment had been undertaken in 2025; this 2026 sailing continues the model. The choice of platform matters. Rather than a frontline destroyer or frigate, the Navy uses INS Sunayna, a Saryu-class Offshore Patrol Vessel (OPV) — a ship built precisely for the constabulary, presence and partnership tasks that this mission performs. The Saryu-class OPVs were constructed at Goa Shipyard Limited and are designed for exclusive-economic-zone surveillance, anti-piracy patrols, escort duties and low-intensity maritime operations rather than high-end blue-water combat. An OPV's value here is exactly its modesty: it is large enough to host a multinational crew and undertake a long regional cruise, but it is unmistakably a presence-and-partnership ship, which keeps the diplomatic signal cooperative rather than threatening to the small states it visits.
The two-phase design of the mission is itself instructive and frequently overlooked. The Harbour Phase (16–29 March 2026) is the period in which the foreign sailors join the ship alongside in port and are integrated into the Indian crew — standardising procedures, language of command, watch routines and safety drills before the ship ever leaves the wall. Only after that integration does the Sea Phase (2 April–20 May 2026) begin, when the now-blended crew takes the ship across the South-Eastern Indian Ocean. This sequence is what allows genuinely mixed manning rather than mere passenger embarkation, and it is the feature that most clearly distinguishes IOS SAGAR from a conventional goodwill port visit.
For Prelims
- Mission name: Indian Ocean Ship (IOS) SAGAR — the ship's mission designation for this deployment, not a permanent ship name.
- Platform: INS Sunayna, a Saryu-class Offshore Patrol Vessel (OPV) of the Indian Navy.
- Crew: India + 16 Friendly Foreign Countries sailing on one jointly-manned vessel.
- Parent doctrine: Vision MAHASAGAR = Mutual and Holistic Advancement for Security and Growth Across Regions (the 2025 widening of the 2015 SAGAR doctrine — Security and Growth for All in the Region).
- Flagged off by: Raksha Rajya Mantri (MoS Defence) Sanjay Seth; Navy Chief Admiral Dinesh K. Tripathi present.
- Timeline: Harbour Phase 16–29 March 2026 · Sea Phase 2 April–20 May 2026.
- Theatre: South-Eastern Indian Ocean Region.
- Route nodes: Mumbai (start) → Colombo (Sri Lanka) → Phuket (Thailand) → Jakarta (Indonesia) → Singapore → Chittagong (Bangladesh) → Yangon (Myanmar) → Male (Maldives) → Kochi (conclusion).
- Training delivered: seamanship, navigation, VBSS (Visit, Board, Search and Seizure), firefighting and damage control.
- Policy frame: Neighbourhood First; India as a "net security provider" / "first responder" in the IOR.
The full SAGAR-doctrine family (for "how many / match-the-pairs" survivability). IOS SAGAR sits inside a cluster of India-led IOR maritime initiatives that aspirants routinely confuse. Keep them paired: SAGAR (2015) — the doctrine of Security and Growth for All in the Region; Vision MAHASAGAR (2025) — its wider re-badging; IOS SAGAR — the jointly-crewed deployment that demonstrates it; IORA — the Indian Ocean Rim Association, the 23-member regional bloc India belongs to (distinct from this Navy mission); IONS — the Indian Naval Symposium, a forum of IOR navies; SAGARMALA — a separate Ministry of Ports/Shipping port-led development programme that has nothing to do with this deployment despite the shared "Sagar" prefix.
How it compares to a peer. Multinational crewing on a single platform sets IOS SAGAR apart from a conventional bilateral or multilateral exercise such as MILAN (the multinational naval gathering India hosts at Visakhapatnam) or MALABAR (the India–US–Japan–Australia Quad-adjacent exercise). In those, each nation brings its own ship and they manoeuvre together; in IOS SAGAR, foreign sailors live and work aboard one Indian ship, which is a deeper interoperability and trust-building model than a passing exercise.
Why it matters
The Indian Ocean carries a large share of the world's seaborne trade and energy, and its sea lanes are vulnerable to piracy, smuggling, illegal fishing and the squeeze of external naval powers. Smaller littoral states often lack the trained manpower and platforms to police their own waters. IOS SAGAR addresses that gap directly: by putting foreign sailors through real watch-keeping, navigation, boarding and damage-control drills aboard an operational Indian ship, India builds partner-navy human capacity while signalling that its naval presence is cooperative rather than coercive.
The mission also answers a strategic problem. As external naval activity in the IOR grows, India seeks to anchor itself as the preferred security partner and first responder for its maritime neighbours — the country that arrives when a cyclone, a stranded fishing fleet or a piracy incident demands help. A jointly-crewed voyage threading Colombo, Male, Chittagong, Yangon and the Southeast Asian ports is a low-cost, high-trust way to keep those relationships warm and to make the Neighbourhood First policy tangible on the water rather than only in communiqués.
There is a skills dimension too. The training menu — seamanship, navigation, VBSS (Visit, Board, Search and Seizure), firefighting and damage control — is not incidental. VBSS is the core boarding skill behind anti-piracy and anti-smuggling interdiction, and firefighting and damage control are the survival disciplines that keep a ship afloat after a casualty at sea. By drilling partner sailors in exactly these tasks, India is transferring the practical competencies that allow small navies and coast guards to police their own waters, which over time reduces the policing burden the region places on any single power. The voyage's geography reinforces the message: the route deliberately touches South Asian neighbours (Sri Lanka, Bangladesh, the Maldives), continental Southeast Asia (Myanmar, Thailand) and maritime Southeast Asia (Indonesia, Singapore), binding the Bay of Bengal and the eastern Indian Ocean into a single arc of cooperation that aligns with India's Act East outlook as much as with Neighbourhood First.
