Background and Evolution of SLINEX
The SLINEX series was conceptualized and first conducted in 2005 to build mutual trust and standardize operational procedures between the Indian Navy and the Sri Lanka Navy. Over the past two decades, the exercise has progressed from basic communication drills and formation steaming into an advanced, multi-threat tactical warfare exercise.
Conducted alternately between Indian and Sri Lankan ports, the exercise serves to:
- Institutionalize communication protocols and tactical signaling.
- Enhance interoperability during conventional combat as well as asymmetric security threats.
- Foster institutional synergy and personal camaraderie between officers and sailors.
Building on the foundation of previous editions, SLINEX-26 expanded the operational scope by including complex anti-submarine warfare simulations, live weapon firings, and underway replenishment exercises.
Key Highlights of SLINEX-26
Hosted under the aegis of the Eastern Naval Command in Visakhapatnam, SLINEX-26 placed strong emphasis on real-world operational readiness.
The core objectives fulfilled during the exercise included:
- Standard Operating Procedures (SOPs): Refining tactical communication channels, tactical maneuvering, and joint radar tracking.
- Maritime Domain Awareness (MDA): Enhancing real-time maritime intelligence sharing to monitor suspicious activities across the Bay of Bengal and the Palk Strait.
- Non-Traditional Threat Response: Strengthening joint capabilities against maritime piracy, drug trafficking, contraband smuggling, and unauthorized fishing.
- Search and Rescue (SAR): Practicing coordinated disaster relief and maritime rescue operations during offshore emergencies.
Participating Warships and Naval Assets
The naval units participating in SLINEX-26 highlighted high levels of technological advancement, self-reliance, and bilateral defense industrial cooperation.
1. INS Kavaratti (P31) – Indian Navy
- Type: Kamorta-class Anti-Submarine Warfare (ASW) Stealth Corvette.
- Indigenization: Designed by the Indian Navy’s Warship Design Bureau and constructed by Garden Reach Shipbuilders & Engineers (GRSE), Kolkata under Project 28.
- Combat Capabilities: Features an advanced carbon-composite superstructure for low radar visibility (stealth), indigenous anti-submarine rocket launchers, heavyweight torpedo tubes, and a sophisticated combat management suite.
2. INS Jyoti (A58) – Indian Navy
- Type: Fleet Replenishment Tanker.
- Operational Role: Specializes in refueling, provisioning, and re-arming combat vessels while underway on the high seas. During SLINEX-26, INS Jyoti conducted multiple Replenishment-at-Sea (RAS) evolutions to demonstrate sustained blue-water deployment capability.
3. SLNS Sindurala (P623) – Sri Lanka Navy
- Type: Advanced Offshore Patrol Vessel (AOPV).
- Significance: Built in India by Goa Shipyard Limited (GSL) and commissioned into the Sri Lanka Navy, standing as a proud example of India’s defense manufacturing exports.
- Operational Role: Equipped with modern surveillance systems, a helicopter landing deck, and rapid-intervention surface craft for maritime patrol and interdiction.
Operational Structure: Harbour Phase vs. Sea Phase
To ensure focused and methodical execution, SLINEX-26 was structured into two operational segments:
1. The Harbour Phase (17–19 September 2026, Visakhapatnam)
The opening phase was centered on professional dialogue, operational planning, and bilateral defense diplomacy:
- Subject Matter Expert Exchanges (SMEE): Delegations exchanged operational knowledge regarding asymmetric threats, coastal surveillance systems, and environmental safety measures.
- Cross-Deck Ship Visits: Officers and sailors toured each other’s warships to study platform capabilities, operational layouts, and bridge protocols.
- Soft Diplomacy & Sports: Personnel engaged in friendly sports matches (cricket and volleyball), joint yoga sessions, and cultural exchange dinners to build interpersonal goodwill.
2. The Sea Phase (20–21 September 2026, Bay of Bengal)
The sea phase tested tactical execution and joint combat capabilities in the open waters of the Bay of Bengal:
- Live Weapon Firings: Ships engaged surface and aerial targets with main and secondary guns to validate weapon coordination.
- Replenishment-at-Sea (RAS) Approaches: Warships conducted close-quarter maneuvering alongside fleet tanker INS Jyoti to simulate underway fuel transfer.
- Aviation & Interdiction Drills: Naval helicopters executed cross-deck landings, while boarding teams practiced Visit, Board, Search, and Seizure (VBSS) procedures against simulated rogue vessels.
Strategic Significance: The MAHASAGAR Doctrine
A central strategic pillar emphasized during SLINEX-26 is its alignment with India’s expanded maritime doctrine: MAHASAGAR.
Understanding MAHASAGAR
- Full Form: Mutual and Activistic / Holistic Advancement for Security And Growth Across Regions.
- Strategic Evolution: Building upon the foundational SAGAR (Security and Growth for All in the Region) initiative, MAHASAGAR signifies a proactive and cooperative framework aimed at:
- Strengthening collective maritime capacity among Indian Ocean littoral states.
- Maintaining an open, transparent, and rules-based international maritime order.
- Solidifying India’s role as the Preferred Security Partner and the First Responder during regional humanitarian crises.
- Safeguarding critical global sea routes connecting Asia, Africa, and Europe.
Through regular editions like SLINEX-26, India and Sri Lanka continue to build the institutional trust necessary to keep the northern Indian Ocean stable and resilient against external security challenges.
Regional Maritime Security Impact
The shared maritime boundary between India and Sri Lanka spans narrow waterways, including the Palk Strait and the Gulf of Mannar. Close coordination between both navies is vital to address common regional security challenges:
- Combating Transnational Crime: Joint monitoring prevents maritime narcotics trafficking, illegal arms movement, and contraband smuggling.
- Protecting Marine Ecology: Coordinated readiness ensures rapid containment of potential oil spills and environmental hazards from major commercial shipping lines.
- Disaster Management: Seamless interoperability guarantees fast, synchronized relief operations during severe regional weather events and cyclones.
