Quick Revision: The INDRA series of naval exercises between India and Russia is a biennial bilateral engagement aimed at enhancing maritime interoperability, operational coordination, and strategic trust, with INDRA-2026 scheduled in Vladivostok from 13 to 18 October 2026.

Why is this in the news?

The Indian Navy’s indigenously built guided missile stealth frigate INS Sahyadri arrived at Vladivostok on 10 October 2026 to participate in the bilateral naval exercise INDRA-2026 with the Russian Navy from 13 to 18 October 2026. This deployment underscores the operational and professional engagement between the two navies, reinforcing maritime security cooperation in the Indo-Pacific region and aligning with India’s broader SAGAR (Security and Growth for All in the Region) vision.

Background

• The INDRA series of bilateral naval exercises between India and Russia was initiated in 2003 and has since become a cornerstone of defence cooperation between the two nations.
• Vladivostok, located in the Russian Far East, serves as a critical naval base for the Russian Pacific Fleet and is strategically positioned to facilitate exercises in the Sea of Japan and the broader Indo-Pacific.
• India’s maritime security doctrine, encapsulated in the SAGAR initiative launched in 2015, emphasizes collective action, mutual trust, and shared responsibility among littoral states for maritime security.
• The 23rd India-Russia Annual Summit held on 4-5 December 2025 provided renewed impetus to defence and maritime cooperation, setting the stage for enhanced military engagements.
• India’s Act East Policy and Russia’s pivot to the Asia-Pacific region have converged to strengthen naval engagements, including port calls, joint exercises, and defence industrial collaboration.
• The Indian Navy’s deployment of INS Sahyadri, a Project 17-class stealth frigate, reflects India’s growing indigenous naval capabilities and its commitment to operationalizing strategic partnerships.

What is the INDRA series of naval exercises?

• The INDRA series is a biennial bilateral naval exercise between the Indian Navy and the Russian Navy, designed to enhance interoperability, professional exchanges, and operational coordination.
• The exercise typically comprises two phases: a harbour phase involving professional interactions, cultural exchanges, and planning sessions, followed by a sea phase featuring coordinated maritime operations.
• Key activities include joint manoeuvres, anti-submarine warfare drills, air defence exercises, maritime surveillance, and search-and-rescue operations, aimed at improving tactical and operational synergy.
• The exercises also facilitate knowledge sharing on advanced naval technologies, tactics, and best practices, thereby enhancing the operational readiness of participating navies.
• The exercise is conducted under the framework of the India-Russia Military-Technical Cooperation Agreement, which governs defence and security engagements between the two countries.
• Participation in such exercises aligns with India’s broader maritime security objectives, including ensuring freedom of navigation, countering piracy, and addressing non-traditional threats in the Indo-Pacific.
• The inclusion of social and cultural exchanges during the harbour phase fosters people-to-people ties, reinforcing the diplomatic and strategic dimensions of the exercise.
