Bilateral Naval Exercise in Colombo
India Sri Lanka Deepen Naval Coordination Through IN SLN DIVEX 2026: India and Sri Lanka jointly conducted the fourth edition of IN–SLN DIVEX 2026 in Colombo from April 21 to 28. The exercise witnessed the participation of the Indian Navy’s specialised diving support vessel INS Nireekshak along with expert divers from the Sri Lankan Navy. The initiative reflected the expanding maritime partnership between both neighbouring countries.
The bilateral exercise mainly focused on underwater diving operations and maritime coordination. Both navies practised advanced techniques to improve operational compatibility during emergency and strategic missions in the Indian Ocean Region.
Static GK fact: Colombo is the commercial capital of Sri Lanka, while Sri Jayawardenepura Kotte is the official legislative capital.
Advanced Deep Sea Operations
A major highlight of the exercise was the successful execution of deep-sea diving beyond 55 metres depth. This operation demonstrated the technical efficiency and preparedness of both naval forces. Divers also performed mixed gas diving drills, which are essential for complicated underwater rescue and repair missions.
The exercise included diving operations near the historic World War-era wrecks SS Worcester and SS Perseus. These missions enhanced practical underwater navigation skills and provided operational exposure in challenging marine environments.
Static GK Tip: Mixed gas diving uses gases like helium and oxygen to prevent nitrogen-related complications during deep underwater missions.
Maritime Security in Indian Ocean
The exercise aimed to improve interoperability between the two navies. Interoperability helps defence forces operate together smoothly during humanitarian operations, rescue activities and security missions. This cooperation is significant because the Indian Ocean Region is one of the world’s busiest maritime trade routes.
The drills improved coordination during maritime emergencies, disaster response operations and underwater search missions. Such exercises also strengthen maritime domain awareness, which helps monitor suspicious activities and secure sea lanes.
Static GK fact: Nearly 80 percent of global maritime oil trade passes through the Indian Ocean Region.
Defence Diplomacy and Strategic Trust
The exercise highlighted the strengthening defence diplomacy between India and Sri Lanka. Rear Admiral SJ Kumara visited INS Nireekshak and appreciated India’s support in training Sri Lankan naval divers. Such interactions build strategic trust and encourage long-term military cooperation.
India and Sri Lanka continue to expand defence partnerships through naval exercises, training exchanges and coastal security initiatives. These engagements contribute to regional peace and stability.
Static GK Tip: India and Sri Lanka are members of regional groupings like BIMSTEC and the Indian Ocean Rim Association.
Humanitarian Cooperation and Cultural Engagement
Apart from military drills, both navies participated in several social and cultural activities. Joint yoga sessions, sports competitions and a beach clean-up drive at Galle Face promoted camaraderie and mutual understanding among personnel.
India also handed over BHISM cubes under the Aarogya Maitri initiative. These portable medical support units are designed for rapid disaster response and healthcare assistance during emergencies. The move highlighted India’s role as a responsible maritime and humanitarian partner in South Asia.
