Background
India and Sri Lanka share long-standing defence and maritime ties shaped by their proximity across the Palk Strait and the Gulf of Mannar. The Indian Navy regularly deploys ships to Colombo and Trincomalee for goodwill visits, joint exercises, and humanitarian assistance. The cooperation framework draws from India's SAGAR doctrine — Security and Growth for All in the Region — articulated in 2015, and its successor vision MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions).
INS Sunayna, commissioned in 2013 and based at Kochi under the Southern Naval Command, is among the vessels frequently tasked with overseas deployments, anti-piracy patrols in the Gulf of Aden, and engagement missions with friendly foreign navies.
The Colombo port call
The arrival of INS Sunayna at Colombo harbour was marked by ceremonial reception by the Sri Lanka Navy. Activities typically associated with such visits include:
- Professional interactions and subject-matter expert exchanges between the two navies.
- Sports fixtures and cultural events to strengthen people-to-people contacts.
- Cross-deck visits and joint training serials.
- A passage exercise (PASSEX) at sea on departure.
Significance
The deployment reinforces India's role as a first responder and preferred security partner in the Indian Ocean. By engaging Colombo through a dedicated regional cooperation mission, India signals continuity in maritime outreach amid heightened strategic competition in the IOR. For Sri Lanka, port calls of this nature support naval interoperability, training exposure, and bilateral confidence-building.
