INS Nireekshak and India's Submarine Rescue Capability

INS Nireekshak is a dedicated Diving Support and Submarine Rescue Vessel of the Indian Navy. It is equipped to carry out saturation diving, deep sea salvage, and submarine rescue operations, filling a critical niche in India's maritime capability. The vessel is part of India's Southern Naval Command, which is headquartered at Kochi.

The ship is named after the Hindi word for "inspector" or "observer."
Its primary roles include: diving support, underwater salvage, submarine rescue, and hydrographic survey assistance.
India maintains one of the few submarine rescue capabilities in the Indo-Pacific region.
The visit marks the 4th consecutive edition of the DIVEX bilateral exercise.

Connection to this news: DIVEX specifically leverages INS Nireekshak's specialised diving and underwater operations profile, making it the designated Indian Navy platform for this bilateral exercise series with Sri Lanka.

India-Sri Lanka Bilateral Defence Exercises

India and Sri Lanka conduct a structured set of bilateral and multilateral military exercises that span all three service arms, reflecting the depth of defence cooperation between the two neighbours separated by the Palk Strait.

SLINEX: Annual bilateral naval exercise conducted alternately in India and Sri Lanka; ongoing since 2004; 12th edition held in 2025.
MITRA SHAKTI: Bilateral army exercise conducted annually, alternating between India and Sri Lanka.
DIVEX: Bilateral naval diving exercise; focuses on underwater operations and submarine rescue; 4th edition in 2026.
DOSTI: Trilateral coastguard exercise involving India, Sri Lanka, and Maldives.
The Indo-Sri Lanka Defence Dialogue has been held since 2012.

Connection to this news: DIVEX 2026 sits within a broader framework of annual bilateral defence exercises that aim to enhance interoperability and operational readiness between the Indian and Sri Lankan navies.

India's Neighbourhood First Policy and Sri Lanka

India's Neighbourhood First Policy, articulated formally around 2014, prioritises strengthening political, economic, and security ties with immediate neighbours — Bangladesh, Nepal, Bhutan, Maldives, Sri Lanka, Pakistan, and Afghanistan. Sri Lanka occupies a strategically sensitive position due to its proximity to India's southern coastline, its location along key maritime trade routes through the Indian Ocean, and its historical people-to-people linkages.

India and Sri Lanka are separated by the Palk Strait at a minimum distance of approximately 31 km.
India is Sri Lanka's largest trading partner and a major source of tourism.
India extended a $4 billion economic assistance package to Sri Lanka during its 2022 economic crisis, the largest bilateral support Sri Lanka received.
The Aarogya Maitri initiative provides medical assistance (BHISM cubes) to friendly nations; two cubes were handed over during DIVEX 2026.
India's concerns in the bilateral relationship include the Tamil question, Chinese naval presence at Hambantota Port, and maritime boundary management in the Palk Bay.

Connection to this news: DIVEX 2026, combined with the humanitarian handovers (BHISM cubes and ammunition), exemplifies India's Neighbourhood First approach: building defence interoperability while reinforcing goodwill through tangible assistance.

BHISM Cubes (Aarogya Maitri Initiative)

BHISM (Bharat Health Initiative for Sahyog Hita & Maitri) is a portable, modular emergency medical kit developed under India's Aarogya Maitri initiative for disaster relief and humanitarian assistance to friendly countries. Each BHISM cube is a self-contained medical unit packed in stackable cubes.

Each unit can handle up to 200 emergency patients.
Contains essential medicines, surgical tools, and diagnostic equipment.
Designed for rapid deployment in disaster zones or conflict-affected areas.
Provided to friendly nations as part of India's soft power and humanitarian diplomacy.
Previously deployed or donated to several countries including Palestine, Turkey (post-earthquake), and now Sri Lanka.

Connection to this news: The handover of two BHISM cubes during DIVEX 2026 demonstrates that Indian Navy port visits serve dual military and humanitarian diplomacy purposes.
