IN-SLN DIVEX 2026 Strengthens Maritime Ties

India and Sri Lanka have deepened naval cooperation through IN-SLN DIVEX 2026, held in Colombo from 21 to 28 April. The fourth edition of the bilateral diving exercise focused on underwater operations, joint rescue capability and maritime security in the Indian Ocean Region.

INS Nireekshak Leads Indian Participation

The Indian Navy deployed INS Nireekshak, a Diving Support and Submarine Rescue Vessel, for the exercise. Diving teams from both navies took part in harbour and open-sea drills to improve coordination and operational familiarity.
