Indian Naval Ship Sunayna, deployed as IOS Sagar, arrived at the Port of Colombo, Sri Lanka on 15 May 2026, underscoring both nations' shared commitment to regional peace, stability, and collective maritime security. The Indian Navy described the visit as a reinforcement of India's MAHASAGAR vision and the government's 'Neighbourhood First' policy.
A Multinational Crew, One Mission
IOS Sagar is crewed by sailors and officers from 16 friendly foreign countries, making it one of the most diverse naval deployments in the Indian Ocean Region (IOR). The participating nations include Sri Lanka, Bangladesh, Indonesia, Kenya, Malaysia, Maldives, Mauritius, Mozambique, Myanmar, Singapore, Seychelles, South Africa, Tanzania, Thailand, Timor-Leste, and the United Arab Emirates.
Upon arrival, the vessel was accorded a traditional naval welcome by the Sri Lanka Navy. According to Sri Lanka's Ministry of Defence, the multinational crew engaged in professional interaction programmes with their Sri Lankan counterparts and undertook cultural excursions to key sites across the island.
Professional Exchanges and Cultural Engagement
During the port visit, naval personnel from the participating nations participated in a series of joint professional programmes with the Sri Lanka Navy. These interactions are designed to build operational familiarity and deepen interoperability — a stated priority under the MAHASAGAR framework, which stands for Mutual and Holistic Advancement for Security and Growth Across Regions.
The Indian Navy described IOS Sagar as embodying the ethos of 'leadership through partnership, strength through unity and progress through peace' — a formulation that signals India's intent to lead through coalition-building rather than unilateral presence in the IOR.
Prior Port Calls and Regional Footprint
The Colombo visit follows a series of port calls that have traced a broad arc across the Indo-Pacific. IOS Sagar previously completed stops at Male, Phuket, Jakarta, and Singapore, before arriving at Chattogram, Bangladesh.
On departure from Chattogram, IOS Sagar participated in a Passage Exercise (PASSEX) with the Bangladesh naval vessel BNS Protoy, supported by naval air assets. The exercise included coordinated maritime drills and advanced surface manoeuvres aimed at enhancing interoperability between the two navies — reflecting the operational, not merely symbolic, dimension of the deployment.
Strategic Significance
The deployment comes at a time of heightened attention to maritime security across the Indian Ocean, with multiple regional powers expanding their naval presence. India's decision to crew IOS Sagar with personnel from 16 nations — spanning South Asia, Southeast Asia, Africa, and the Gulf — is a deliberate signal of inclusive regional leadership.
This is the latest in a series of Indian Navy deployments under the MAHASAGAR and Neighbourhood First frameworks, both of which prioritise collaborative maritime architecture over bilateral-only engagements. The Sri Lanka leg of the deployment is expected to be followed by further port calls as IOS Sagar continues its operational deployment in the IOR.
Point of View
Southeast Asia, East Africa, and the Gulf, India is constructing a maritime consensus in real time. The MAHASAGAR framework has often been described in policy documents; this deployment is its operational proof of concept. What mainstream coverage underplays is the sequencing: Male, Phuket, Jakarta, Singapore, Chattogram, Colombo — the route itself maps India's strategic perimeter. The PASSEX with Bangladesh and the professional exchanges in Colombo signal that this is not a goodwill tour but a capability-building exercise with alliance implications.
