INS Sahyadri at Vladivostok for INDRA-2026: Dates, Context and Key Facts

INS Sahyadri arrived at Vladivostok, Russia, on 10 October 2026 to take part in INDRA-2026, a bilateral exercise between the Indian Navy and the Russian Federation Navy (RuFN). The exercise is scheduled for 13 to 18 October 2026. It matters because it shows India's naval engagement with Russia in the Pacific and ties into the MAHASAGAR vision and the 23rd India-Russia Annual Summit.

INDRA-2026 status as of 13 October 2026

The sources are dated differently from the event. The arrival took place on 10 October 2026. The PIB (Ministry of Defence) release is dated 11 October 2026, and the GKToday article is dated 12 October 2026. Both came out before the exercise window opened, so neither reports outcomes. This page therefore treats the exercise as scheduled, not completed.

What the sources say about the exercise

Participants and purpose

INDRA-2026 is a bilateral naval exercise between the Indian Navy and the Russian Federation Navy. PIB says the deployment offers professional engagements and operational interaction. These are meant to further maritime cooperation and interoperability, which means the two navies' ability to work together.

Planned format

The exercise has two parts: a harbour phase, followed by coordinated operational activities at sea. PIB adds that social and cultural interactions will let personnel of both navies build camaraderie and people-to-people connections.

Details given by only one source

• GKToday says the harbour phase is in Vladivostok and the sea phase includes drills in the Sea of Japan. PIB does not name the sea area.
• GKToday says Russia's participating vessel is the corvette Hero of the Russian Federation Aldar Tsydenzhapov, and that Russia's Pacific Fleet is involved. PIB does not mention either.

Treat these details as reported by GKToday alone. The sources do not say how many ships or aircraft are taking part or what specific drills are planned.

Why it matters: MAHASAGAR and the India-Russia link

PIB says INS Sahyadri's participation is in line with the Government of India's MAHASAGAR vision. The full form is Mutual and Holistic Advancement for Security and Growth Across Regions. PIB also says the deployment builds on the longstanding defence and maritime partnership between India and Russia. It adds that the deployment helps carry forward the momentum of the 23rd India-Russia Annual Summit, held on 4–5 December 2025.

INS Sahyadri and the Shivalik class

According to GKToday, INS Sahyadri is a Shivalik-class stealth multi-role frigate. The class comprises INS Shivalik, INS Satpura and INS Sahyadri. They were built by Mazagon Dock Shipbuilders Limited in Mumbai, and Sahyadri was commissioned in 2012. GKToday describes a frigate as a surface combatant used for escort, surveillance and anti-submarine warfare roles. These ship details come from GKToday only, and PIB does not repeat them.

• Vladivostok: a Russian port city on the Pacific coast and, per GKToday, a major base of Russia's Pacific Fleet.
