PIB TrackerA twenty-one-year-old exercise reaches its thirteenth edition
SLINEX-26 runs at Visakhapatnam from 17 to 21 September with an indigenous anti-submarine corvette and a fleet tanker. Conceptualised in 2005, the exercise has averaged one edition every twenty months.
What happened
- SLINEX-26, the 13th edition, runs at Visakhapatnam from 17 to 21 September 2026.
- India fields INS Kavaratti, an indigenous anti-submarine warfare corvette, and INS Jyoti, a fleet tanker.
- Sri Lanka is represented by SLNS Sindurala.
- The Harbour Phase runs under the Eastern Naval Command; a Sea Phase on interoperability follows.
- SLINEX was conceptualised in 2005 and is aligned with the MAHASAGAR vision.
For Prelims
- SLINEX: the Sri Lanka-India bilateral maritime exercise, conceptualised in 2005, now in its 13th edition - roughly one every twenty months.
- INS Kavaratti: an indigenously built anti-submarine warfare corvette - the capability, not the tonnage, is the signal in a bilateral exercise.
- INS Jyoti: a fleet tanker, which supplies fuel and stores at sea and is what allows a navy to stay deployed rather than return to port.
- Harbour Phase and Sea Phase: the standard two-part structure - familiarisation and planning alongside the pier, then coordinated serials at sea.
- Cross-deck visits: officers and sailors working aboard the other navy's ship - the cheapest and most durable form of interoperability building.
- Eastern Naval Command: headquartered at Visakhapatnam, the command hosting this edition and the one facing the Bay of Bengal.
- MAHASAGAR: the stated Indian maritime vision the exercise is aligned with, framed around a secure, stable and inclusive maritime environment.
- Why an ASW corvette: submarine detection in near waters is the capability most relevant to the narrow sea between India and Sri Lanka, and the one hardest to build alone.
For UPSC: A compact instance of neighbourhood defence diplomacy conducted through routine rather than summitry. Use it on India-Sri Lanka relations and the Neighbourhood First policy, on maritime security in the Indian Ocean Region, and on defence exercises as an instrument, where the irregular cadence is the honest qualifier.
What it is NOT: The release names no exercise objective beyond interoperability, no serial to be conducted in the Sea Phase, and no participating aircraft, submarine or special forces element. It gives no date or location for the previous edition, so the interval since SLINEX-25 cannot be computed, and the twenty-one-year average is derived from 2005 and thirteen editions rather than stated. It says nothing about the wider state of India-Sri Lanka defence cooperation, names no agreement or framework, and does not mention fishing, maritime boundary or Palk Strait issues that dominate the bilateral maritime relationship.

Anchor
SLINEX-26 is the thirteenth edition of an exercise conceptualised in 2005. Thirteen editions across twenty-one years is roughly one every twenty months, not the annual rhythm the name suggests. The exercise is real, sustained and irregular, which is a fair description of the defence relationship it represents.
Substantiation (data)
India fields INS Kavaratti, an indigenously built anti-submarine warfare corvette, and INS Jyoti, a fleet tanker. Sri Lanka fields SLNS Sindurala. The exercise runs at Visakhapatnam from 17 to 21 September under the Eastern Naval Command, in a Harbour Phase followed by a Sea Phase.
Position
The ship selection is the message. An anti-submarine corvette and a tanker are capability and endurance, not firepower. Submarine detection in the narrow waters between the two countries is precisely the task a smaller navy cannot do alone, and a tanker is what lets either navy stay at sea rather than return to harbour.
Exemplification
The Harbour Phase content is easy to dismiss and should not be. Cross-deck visits, shared best practices and professional interaction are how two navies learn each other's procedures, and procedural familiarity is what actually determines whether a joint response works in an emergency at sea.
Problematisation
Twenty-one years and thirteen editions is a thin institutional record for a maritime neighbour whose waters India shares. The release names no serial, no objective beyond interoperability and no framework agreement, and says nothing about the fishing and maritime boundary disputes that define the relationship in practice.
Conclusion
The defensible claim is modest: India and Sri Lanka maintain a working naval relationship built on repetition rather than agreement. For the Neighbourhood First argument that is useful evidence, provided the answer says thirteen editions in twenty-one years rather than implying an annual exercise.
