Overview of IN–SLN DIVEX 2026
IN–SLN DIVEX 2026 is a bilateral naval exercise scheduled for 2026 in the Bay of Bengal, involving the Indian Navy (IN) and the Sri Lanka Navy (SLN). This exercise focuses on anti-submarine warfare and maritime interdiction operations, incorporating live firing drills, search and rescue operations, and electronic warfare simulations (Press Information Bureau, 2024). Since 2000, India and Sri Lanka have conducted over 15 such bilateral naval exercises to enhance interoperability (Indian Navy Annual Report 2023). The exercise exemplifies the strategic deepening of maritime defence cooperation between the two countries, contributing to the Indo-Pacific regional security architecture.

Legal and Constitutional Framework Governing IN–SLN DIVEX
The exercise is governed by the Defence of India Act, 1962 and the Indian Navy Act, 1957, which regulate naval operations and international defence cooperation. It aligns with the Ministry of Defence’s policy framework under the Defence Cooperation Agreement between India and Sri Lanka (2000), which institutionalizes bilateral defence engagements. The Integrated Defence Staff (IDS) facilitates joint operations and interoperability among Indian Armed Forces, ensuring compliance with legal and operational protocols during such exercises.
- Defence of India Act, 1962: Provides legal basis for defence preparedness and cooperation.
- Indian Navy Act, 1957: Governs naval personnel, operations, and international exercises.
- Defence Cooperation Agreement (2000): Bilateral framework for defence collaboration between India and Sri Lanka.
- Indian Maritime Doctrine (2015): Guides naval operational conduct including joint exercises.
Economic Dimensions of the Exercise
India’s Union Budget 2023-24 allocated ₹1.40 lakh crore for naval modernization, reflecting a strategic investment in maritime security capabilities. In contrast, Sri Lanka’s defence expenditure was approximately 2.5% of GDP in 2022 (SIPRI), indicating limited resources for independent capability enhancement. Joint exercises like IN–SLN DIVEX 2026 are critical for Sri Lanka to leverage India’s advanced naval assets and expertise, optimizing resource utilization and capacity building.
- India’s naval budget supports acquisition of 150+ ships and submarines (SIPRI 2023).
- Sri Lanka Navy operates about 40 vessels, constrained by budget limitations.
- India’s maritime trade accounts for over 90% of total trade volume (Ministry of Commerce, 2023), underscoring the economic imperative of securing sea lanes.
- Sri Lanka’s EEZ spans 517,000 sq km, requiring robust maritime security cooperation (UNCLOS).
Institutional Roles in IN–SLN DIVEX 2026
The Indian Navy leads operational planning and execution, deploying advanced platforms and personnel. The Sri Lanka Navy participates actively, gaining operational experience and interoperability skills. The Ministry of Defence (MoD), India oversees policy formulation and bilateral coordination. The Integrated Defence Staff (IDS) ensures joint operational coherence and facilitates communication between services. These institutions collectively enable the exercise to meet strategic and tactical objectives.
- Indian Navy: Executes maritime warfare operations and leads joint drills.
- Sri Lanka Navy: Engages in capacity building and operational interoperability.
- Ministry of Defence (India): Policy oversight and diplomatic coordination.
- Integrated Defence Staff: Joint operations facilitation and interoperability enhancement.
Strategic and Operational Significance
IN–SLN DIVEX 2026 strengthens bilateral trust and maritime domain awareness in the Bay of Bengal, a critical segment of the Indo-Pacific. The focus on anti-submarine warfare addresses emerging underwater threats, while maritime interdiction operations enhance counter-piracy and smuggling capabilities. The exercise also demonstrates India’s commitment to regional security partnerships, complementing its broader Indo-Pacific strategy.
- Enhances joint operational readiness against asymmetric maritime threats.
- Improves intelligence sharing and maritime domain awareness.
- Supports India’s vision of a secure and stable Indo-Pacific region.
- Augments Sri Lanka’s maritime security capabilities amid resource constraints.
Comparative Analysis: IN–SLN DIVEX vs. US-Japan Malabar Exercises
| Aspect | IN–SLN DIVEX | US-Japan Malabar Exercise |
|---|---|---|
| Participants | India and Sri Lanka (bilateral) | Initially US and Japan; now trilateral including Australia and India |
| Focus Areas | Anti-submarine warfare, maritime interdiction, search and rescue | Carrier strike group operations, anti-submarine warfare, missile defence |
| Strategic Objective | Regional trust-building and South Asian maritime security | Power projection and Indo-Pacific security architecture |
| Command Structure | No formal joint command or permanent task force | Structured trilateral command with integrated task groups |
| Scale | Moderate, focused on interoperability and capacity building | Large-scale, involving multiple carrier strike groups and advanced platforms |
Critical Gaps in India-Sri Lanka Maritime Cooperation
Despite frequent exercises, there is no formalized joint command structure or permanent maritime task force between India and Sri Lanka. This limits rapid operational coordination during crises, reducing the potential effectiveness of combined responses. Additionally, Sri Lanka’s resource constraints hinder sustained capability enhancement, necessitating more institutionalized capacity-building mechanisms.
- Absence of permanent joint command limits crisis response speed.
- Resource asymmetry affects balanced operational readiness.
- Need for formalized communication protocols and shared intelligence frameworks.
- Potential for expanding scope beyond exercises to real-time joint patrols.
Way Forward: Enhancing IN–SLN Maritime Cooperation
- Establish a formal joint maritime command or task force to enable rapid crisis response.
- Institutionalize regular intelligence sharing and joint maritime domain awareness initiatives.
- Expand exercise scope to include cyber and electronic warfare dimensions.
- Leverage India’s naval modernization to provide training and technological support to Sri Lanka.
- Integrate IN–SLN cooperation within broader Indo-Pacific security frameworks without diluting bilateral focus.
- IN–SLN DIVEX 2026 is a multilateral naval exercise involving India, Sri Lanka, and Australia.
- The exercise focuses on anti-submarine warfare and maritime interdiction operations.
- The Defence Cooperation Agreement between India and Sri Lanka was signed in 2000.
