Indian Navy submarine INS Sindhukesari arrived at the port of Colombo, Sri Lanka on 3 May 2026 for an operational turnaround, reinforcing the deepening maritime partnership between India and Sri Lanka in the Indian Ocean Region. The submarine and its crew were ceremonially received by Sri Lanka Navy personnel and the Indian Defence Advisor, Sri Lanka, in keeping with naval traditions.
Purpose of the Visit
According to an Indian Navy spokesperson, the visit aimed at "enhancing interoperability and operational synergy with Sri Lanka Navy." The operational turnaround allows the crew to replenish supplies and undertake scheduled maintenance activities while in a friendly port. During its stay, the crew is scheduled to participate in several programmes organised by the Sri Lanka Navy, including visits to tourist attractions across the island.
Coming on the Heels of Joint Diving Exercise
The arrival of INS Sindhukesari follows closely on the fourth edition of the bilateral diving exercise, IN–SLN DIVEX 2026, conducted in Colombo from 21 to 28 April 2026. The exercise featured participation of the Indian Navy's Diving Support and Submarine Rescue Vessel, INS Nireekshak, along with diving teams from both navies.
According to a statement by the Ministry of Defence, the exercise featured advanced deep-sea diving evolutions, including mixed gas diving drills. Divers from both navies undertook extensive harbour and open-sea dives, with a key highlight being mixed gas dives off Colombo over World War-era wrecks — SS Worcester and SS Perseus. Divers executed deep-sea dives beyond 55 metres, enhancing joint capabilities in underwater search, rescue, and salvage operations.
Senior Naval Officials Weigh In
Rear Admiral SJ Kumara, Sri Lanka's Flag Officer Commanding Western Naval Area, visited INS Nireekshak during the exercise and praised the Indian Navy's continued support in advancing the training of Sri Lankan divers. He highlighted the importance of sustained exchange of best practices and professional expertise between the two navies.
INS Nireekshak's Commanding Officer also paid homage at the IPKF Memorial, laying a wreath in honour of Indian soldiers who made the supreme sacrifice during peacekeeping operations in Sri Lanka — a gesture underscoring the historical depth of bilateral ties.
Humanitarian and People-to-People Initiatives
Beyond operational engagements, the exercise fostered camaraderie through joint activities including a beach clean-up drive at Galle Face, friendly sports fixtures, and yoga sessions. Additionally, two Bharat Health Initiative for Sahyog, Hita and Maitri (BHISM) cubes were handed over under India's Aarogya Maitri initiative, enhancing disaster response and medical preparedness in Sri Lanka.
Taken together, these engagements signal a sustained and multi-dimensional India-Sri Lanka naval partnership that goes well beyond port calls, with the next phase of joint exercises and capacity-building efforts expected to deepen further in the months ahead.
Point of View
It underscores India's consistent effort to keep Sri Lanka within its security orbit through operational familiarity rather than rhetoric. The layering of a submarine visit over a joint diving exercise, a humanitarian handover, and an IPKF memorial wreath-laying is deliberate signalling: India is positioning itself as Sri Lanka's indispensable maritime partner. The real test will be whether these engagements translate into formal basing or logistics-access arrangements, which would represent a qualitative leap in the bilateral relationship.
