CONCLUSION OF INDIA-RUSSIA BILATERAL NAVAL EXERCISE (INDRA 2026)

1. At a Glance

• INDRA is a bilateral naval exercise between the Indian Navy and the Russian Federation Navy (RuFN). The 2026 edition ended at Vladivostok, and INS Sahyadri left the port on 20 Oct 2026 [1].
• It is one of the oldest continuing defence engagements between India and Russia. The series began in 2003 [5]. INDRA is also the name of a separate India–Russia Army exercise, which makes it a common source of confusion in Prelims [8].
• For Mains, it links to India–Russia strategic ties, maritime diplomacy, India's Indo-Pacific / MAHASAGAR outreach, and strategic autonomy [2].

2. Why in the News

• INS Sahyadri arrived at Vladivostok on 10 Oct 2026 for INDRA-2026. The exercise was scheduled for 13–18 Oct 2026 [2].
• PIB announced the conclusion on 23 Oct 2026. The ship departed Vladivostok on 20 Oct 2026 [1].
• PIB placed the deployment in the context of the MAHASAGAR vision and the 23rd India–Russia Annual Summit (December 2025) [2].

3. Background & Evolution

• 2003: The INDRA naval series began [5].
• 2005: INDRA-2005 was held off Visakhapatnam [6].
• 2014: INDRA 2014 followed an Indian Navy port call at Vladivostok [7].
• 2020 (11th edition): Held in the Bay of Bengal on 4–5 Sep 2020. Because of COVID-19 it was "non-contact, at sea only". India sent INS Ranvijay, Sahyadri and Shakti, and Russia sent ships from its Pacific Fleet [5].
• 2021 (12th edition, "INDRA NAVY-21"): Held in the Baltic Sea on 28–29 Jul 2021 during INS Tabar's visit to St Petersburg. Russia fielded two Baltic Fleet corvettes [4].
• 2025 (14th edition): Held off Chennai from 28 Mar to 2 Apr 2025. The Harbour Phase ran at Chennai (28–30 Mar) and the Sea Phase in the Bay of Bengal (31 Mar–2 Apr) [3][8][9].
• 2026: Held at Vladivostok and in the Russian Far East, 13–18 Oct 2026 [2][1].

4. Core Static Facts

5. Multi-Dimensional Analysis

Geopolitical / Strategic

• Holding the exercise at Vladivostok, where Russia's Pacific Fleet is based [5], gives India operational presence in the North-West Pacific. This fits an Indo-Pacific reach that runs from the South China Sea (Sahyadri's 2025 call at Kemaman, Malaysia) [11] to Subic Bay (ADMM-Plus, Sep 2026) [10].
• PIB links the deployment to the 23rd Annual Summit (Dec 2025) [2]. The navy is being used as an instrument of political-level commitments.
• The exercise sits alongside India's engagement with Western and Quad navies, so it signals strategic autonomy and multi-alignment.

Security / Operational

• The stated aims are interoperability, communications and coordinated procedures at sea [1].
• The 2026 drills were mostly HADR-type and constabulary in character (medical evacuation, helicopter operations, communications) [1]. The 2025 edition included live weapon firings, anti-air operations and helicopter cross-deck landings [3]. The scope therefore varies by edition.

Technological

• INS Sahyadri is an indigenously built Shivalik-class stealth frigate [13], which showcases Aatmanirbharta in warship building. Follow-on frigates Udaygiri and Himgiri are to join the Eastern Fleet [13].
• A large part of India's naval inventory is of Russian origin, so interoperability with Russia has practical value for maintenance and doctrine.

Diplomatic / Soft power

• Sports, cultural exchanges and cross-deck visits build people-to-people and institutional ties between the two navies [1].

Historical

• The series has continued for over two decades, including through COVID-19, when it ran in a non-contact format [5]. This shows how resilient the defence relationship is.

• In the 2025 edition the Russian ship Aldar Tsydenzhapov took part, along with India's P-8I aircraft [3].

8. Why a Drill With Russia Is Also About Keeping Indian Ships Flying

• The Navy still needs Russia to keep many of its aircraft working
• The Navy told the Standing Committee on Defence (2024) that many of its aviation assets are of Russian origin [14].
• So it still depends on OEMs (original equipment manufacturers, the company that first built the equipment) for maintenance and spare parts [14].

• This is why the Navy cannot treat its working relationship with the Russian Navy as optional, whatever the politics.

• There is an official ban on OEMs, and it is waived case by case

• The Ministry of Defence has an embargo (a ban) on engaging OEMs [14].
• An Empowered Committee under the Ministry grants case-by-case waivers so that overseas maintenance and purchases can continue [14].

• The rule says "build at home". Real needs keep forcing exceptions, and each exception has to be cleared through a separate approval.

• Russia may not deliver parts in a crisis

• PRS notes that in an emergency, a foreign supplier may not provide the weapons or spare parts India needs [14].
• Russia is fighting its own war and putting its own forces first. A friendly drill does not guarantee that spares will arrive on time.

9. The Same Promises, Repeated Summit After Summit

• Making Russian spares in India: agreed twice, in almost the same words
• The 22nd Summit (2024) joint statement promised to encourage joint manufacturing in India of spare parts for Russian-origin arms under Make in India [18].
• The 23rd Summit (Dec 2025) repeated nearly the same wording [15].

• When a promise is copied from one summit to the next, it usually means little has happened on the ground.

• The logistics pact has been "under preparation" since 2019

• In 2019, at Vladivostok, the two sides agreed to prepare a framework for reciprocal logistics support. This means each side's forces could use the other's bases for fuel, repairs and supplies [16].
• The 2021 joint statement only said again that such an arrangement was "required" [17].

• The official texts checked for this note do not report the pact as signed. A ship visiting Vladivostok therefore still depends on port-call arrangements made one visit at a time.

• INDRA is praised at summits but given no new goals

• The 23rd Summit statement "appreciated" the INDRA exercises and promised to "maintain the momentum" [15].
• It set no new goal for the exercise, such as harder drills or a fixed schedule. INDRA is kept going for continuity, not grown in ambition.

10. Does Drilling With Russia Hurt India's Western Partnerships?

• The strongest objection
• Russia is under Western sanctions and is at war. Exercising with its Pacific Fleet at Vladivostok can look to the US, Japan and Europe as if India is taking sides.

• Those are the same partners India works with in the Quad and the Indo-Pacific.

• The answer: look at what was actually practised

• The 2026 Sea Phase covered manoeuvring together, communications, helicopter operations and medical evacuation [1].
• These are low-end drills that any two navies can do. The 2025 edition included live weapon firing and anti-air drills [3]. This year's softer menu suggests India kept the political signal small.

• The same ship, INS Sahyadri, had finished an ADMM-Plus maritime security activity at Subic Bay with ASEAN-led partners just weeks earlier [10]. One ship working with both sides in one deployment shows multi-alignment (working with many partners without choosing one camp) in practice.

• What the objection gets right

• Multi-alignment is easier to claim than to carry out when India still depends on one side for spare parts [14].
• Strategic autonomy (freedom to choose one's own foreign policy) is real only if India could say no to Russia. Today it cannot say no to Russian maintenance support [14].

11. What India Should Push For Next

• Ministry of Defence: turn the spares promise into named projects
• The 2024 and 2025 summit texts both promise joint manufacturing of spares in India through technology transfer and joint ventures [18][15].

• The next summit should list specific joint ventures and parts, with dates. This is how progress can be checked instead of the same wording being repeated.

• Navy and MoD: reduce dependence on waivers for aviation maintenance

• At present, each overseas repair needs a separate waiver from the Empowered Committee [14].

• Building repair capability for Russian-origin aircraft in India would cut the number of waivers and make the Navy safer from supply shocks in wartime [14].

• Keep building warships at home, as the frigate pipeline already does

• Sahyadri is Indian-built, and the Project 17A frigates Udaygiri and Himgiri are joining the same Eastern Fleet [13].

• Each Indian-built ship means less need for foreign maintenance in future. This, more than any exercise, is what protects strategic autonomy.

• MEA and MoD: either finish the logistics pact or stop listing it

• It has stayed at the "framework" stage since 2019 [16][17].
• Concluding it would make Far East deployments like INDRA 2026 easier to plan and repeat.

12. Anchors for Answers

• Data: The Navy told the Standing Committee on Defence (2024) that many of its aviation assets are Russian-origin, so it still depends on OEMs for maintenance and spares [14]
• Report/Committee: Standing Committee on Defence (2024) findings on OEM dependence, as summarised in PRS, Demand for Grants 2026-27 Analysis: Defence [14]
• Law/Case: India–Russia Agreement on Military-Technical Cooperation 2021–2031, the 10-year framework for defence cooperation [8]
• Comparison: The same ship (INS Sahyadri) worked with ASEAN-led ADMM-Plus partners at Subic Bay (Sep 2026) and with Russia at Vladivostok (Oct 2026) [10][1]
• Scheme: Make in India: joint manufacturing of spares for Russian-origin equipment, promised at the 22nd and 23rd Summits [18][15]

13. Mains Relevance

• GS-II: "Bilateral, regional and global groupings and agreements involving India and/or affecting India's interests", and "Effect of policies and politics of developed and developing countries on India's interests".
• GS-III: "Security challenges and their management", and maritime security.
• Possible question stems: 1. "Defence cooperation remains the bedrock of India–Russia relations despite shifting global alignments." Examine this with reference to recent joint military exercises. (15 marks) 2. Discuss the role of naval diplomacy in advancing India's Indo-Pacific strategy. How do exercises with diverse partners reflect India's strategic autonomy? (10 marks) 3. Bilateral exercises are said to be as much about signalling as about interoperability. Evaluate this in the context of India's maritime engagements. (10 marks)

15. NCERT Concepts to Revise

• Technology transfer (Economy): Summit texts promise joint manufacturing of Russian-origin spares in India through technology transfer, reducing dependence on Russian maintenance.
• Economic sanctions (Economy): Russia faces Western sanctions, which is why drilling with its Pacific Fleet raises questions about India's Western partnerships.
• Chennai-Vladivostok Eastern Maritime Corridor (Geography): Sea route linking India's east coast to Vladivostok, the Far East dimension of India–Russia ties behind this deployment.
• Standing committee (Polity): The note's evidence on Navy dependence on Russian-origin aviation spares comes from the Standing Committee on Defence.
• South China Sea (Geography): Sahyadri's earlier Indo-Pacific deployment passed through this contested sea, showing the reach of India's naval diplomacy.

16. Common Errors / Trap Areas

• Navy vs Army INDRA. Both had a "14th edition" in 2025: the naval one at Chennai (Mar–Apr) and the army one at Bikaner (Oct) [3][8].
• Edition numbering. PIB gives numbers for 2020 (11th), 2021 (12th) and 2025 (14th) [5][4][3]. The 2026 conclusion release gives no edition number, so do not assume "15th" without confirmation [1].
• "Biennial" label. Editions were held in consecutive years (2020, 2021, 2025, 2026), so do not treat the exercise as strictly biennial [5][4][3][1].
• Venue confusion. The venue rotates: Visakhapatnam in 2005, Vladivostok in 2014 and 2026, the Baltic Sea in 2021, and Chennai/Bay of Bengal in 2025 [6][7][4][3][1].
• Ship class. Sahyadri is a Shivalik-class frigate (Project 17), not a Delhi- or Kolkata-class destroyer [13].
