India's MAHASAGAR initiative reshapes Indo-Pacific maritime security strategy

Launched in 2015, SAGAR was designed to signal that India does not view the Indian Ocean as a theatre for dominance, but as a shared 'commons.'

  • Security: Safeguarding India's mainland and islands while ensuring a stable maritime environment.
  • Growth: Leveraging the Blue Economy-sustainable use of ocean resources for economic growth.
  • Inclusivity: Promoting a 'consultative' rather than 'command' approach with smaller littoral nations like Mauritius, Seychelles, and Sri Lanka.

Evolution: From SAGAR to MAHASAGAR

In March 2025, the vision was elevated to MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions).

  • Geographic Expansion: While SAGAR was focused on the immediate Indian Ocean Region (IOR), MAHASAGAR extends India's reach across the entire Indo-Pacific, connecting with partners in Southeast Asia, East Africa, and the wider Global South.
  • Shift in Role: India has transitioned from being a 'Net Security Provider' to being the 'Preferred Security Partner' and 'First Responder' for regional crises (e.g., Operation Brahma for earthquake relief in Myanmar in 2025).

Major Pillars & Initiatives

A. Maritime Convergence: Milan 2026

In February 2026, India hosted a historic triple convergence in Visakhapatnam:

  1. International Fleet Review (IFR) 2026: A showcase of indigenous naval power, including INS Vikrant and Visakhapatnam-class destroyers.
  2. Exercise MILAN 2026: One of the largest multilateral naval exercises in history, featuring over 50 navies.
  3. IONS Conclave of Chiefs: India assumed the Chairmanship of the Indian Ocean Naval Symposium (2025-2027), driving regional policy on HADR (Humanitarian Assistance and Disaster Relief).

B. Security Architecture

  • Information Fusion Centre (IFC-IOR): Based in Gurugram, it has become the 'central nervous system' for regional security, sharing real-time data on 'dark shipping' and pirate movements with over 25 partner nations.
  • Operation Sagar Bandhu (March 2026): A recent initiative where the Indian Army launched major bridge and infrastructure projects in Sri Lanka, demonstrating the 'Growth' aspect of the vision through developmental diplomacy.

Climate & Ecology

  • ASEAN-India Year of Maritime Cooperation (2026): A dedicated year focused on 'Climate-Security Convergence,' treating rising sea levels and ocean pollution as shared security threats.

SAGAR vs. MAHASAGAR

| Feature | SAGAR (2015-2024) | MAHASAGAR (2025-Present) | | --- | --- | --- | | Scope | Regional (Indian Ocean) | Global (Indo-Pacific / Global South) | | Identity | Net Security Provider | Preferred Security Partner | | Primary Focus | Counter-piracy & Blue Economy | Hybrid threats, Climate change, & AI-driven MDA | | Key Partners | Mauritius, Seychelles, Maldives | ASEAN, East African states, QUAD |

The Way Forward

The 2026 conflict in West Asia has acted as a stress test for this vision. By maintaining its role as a 'stabilizing hub' amidst the Iran-Israel-US conflict, India is proving that its SAGAR/MAHASAGAR doctrine is not just rhetoric, but a functional framework for protecting global supply chains.
