Abstract
The strategic trajectory of the defense relationship between New Delhi and Moscow, traditionally characterized by a buyer-seller dynamic, is currently undergoing a profound structural metamorphosis driven by the imperatives of the “Make in India” initiative and the geopolitical constraints imposed by Western sanctions. This document analyzes the resilience and adaptation of this bilateral axis following the explicit assurances provided by Sergey Chemezov, the Director General of Rostec, at the Dubai Airshow regarding Russia‘s commitment to supplying critical weaponry to India regardless of external pressure. The purpose of this analysis is to empirically evaluate the feasibility of Moscow‘s offer against the backdrop of New Delhi‘s diversification strategy, quantifying the shift from direct procurement to co-development and technology transfer. The inquiry is situated within the complex matrix of 2025 global security dynamics, where India seeks to balance its legacy dependence on Russian hardware—which constitutes approximately 60% to 70% of its active arsenal according to the Stockholm International Peace Research Institute (SIPRI)—with its burgeoning strategic partnership with the United States and France.
The methodological approach utilized herein involves a rigorous triangulation of defense trade data, official parliamentary standing committee reports from the Lok Sabha, and strategic assessments from authoritative bodies such as the International Institute for Strategic Studies (IISS) and the Observer Research Foundation (ORF). By synthesizing data from the Ministry of Defence India‘s “Annual Report 2023-24” and SIPRI‘s “Trends in International Arms Transfers, 2024,” the analysis deconstructs the specific categories of equipment mentioned by analysts like Harpreet Sidhu of GlobalData Plc, specifically focusing on Long-Range Strike capabilities, Air Defence Systems, and Naval Platforms. The investigation eschews speculative narratives in favor of a hard-data assessment of supply chain vulnerabilities, payment mechanism workarounds (specifically the Rupee-Ruble arrangement), and the technological absorption capacity of Indian Defence Public Sector Undertakings (DPSUs).
Key findings indicate that while the overall volume of Russian arms exports to India has seen a statistical decline—dropping by 34% between the periods 2014–18 and 2019–23 as noted in SIPRI data—the strategic value of the transfers has paradoxically increased. The relationship has stripped away commodity-level transactions to focus on high-value, “deep-tech” cooperation that Western partners are often reluctant to provide. This is most evident in the domain of Long-Range Strike & Missiles, where the BrahMos joint venture serves as the paradigmatic model for future cooperation. The analysis confirms that New Delhi’s immediate procurement priorities are not for new platforms, but for the sustainment and upgrade of the vast existing fleet, particularly the Su-30MKI fighter jets and the T-90S main battle tanks. The “Super Sukhoi” upgrade program, aimed at enhancing the avionics and radar capabilities of the Indian Air Force (IAF)’s backbone, relies heavily on Russian technical inputs, even as India integrates indigenous weapons and Western sensors.
Furthermore, the document highlights the critical role of Air-Defence Systems, specifically the S-400 Triumf. Despite the threat of sanctions under the Countering America’s Adversaries Through Sanctions Act (CAATSA), India has proceeded with the induction of these systems, underscoring Moscow‘s indispensable role in India‘s area denial strategy vis-à-vis China. The analysis of Naval Platforms reveals a similar dependency; while surface ship construction has largely indigenized, the underwater domain—specifically regarding the Kilo-class submarine life-extension and the lease of nuclear-powered attack submarines (SSN)—remains a Russian preserve. The Chakra III lease agreement and potential collaboration on the P-75I project (though competed by Germany and Spain) demonstrate that Russia offers niche capabilities in nuclear propulsion and hull technologies that are currently inaccessible to India from other sources.
The investigation also scrutinizes the economic infrastructure underpinning these transfers. The suspension of standard banking channels due to SWIFT sanctions necessitated the creation of alternative payment mechanisms. The “Vostro” account system, managed by the Reserve Bank of India (RBI) and Russian banks, has faced liquidity challenges due to the trade imbalance favoring Russia (driven by oil imports). However, the document finds that defense contracts are increasingly being structured to utilize these accumulated Rupee reserves for reinvestment into Indian joint ventures, effectively funding the “Make in India” ecosystem. This creates a closed-loop economic model that incentivizes Russia to localize production within India to utilize its Rupee assets, aligning perfectly with Prime Minister Narendra Modi‘s vision of defense self-reliance.
In the domain of Space and Electronic Warfare, the document assesses the potential for cooperation in satellite-based Intelligence, Surveillance, and Reconnaissance (ISR) and anti-drone systems. The war in Ukraine has accelerated Russian innovation in Electronic Warfare (EW), and India, facing a hostile border environment with high drone proliferation, views these combat-proven solutions as highly relevant. The analysis suggests that Russia is willing to share these tactical technologies to maintain market share against encroaching Israeli and French suppliers.
The conclusions drawn from this exhaustive review posit that the Russia-India defense relationship is not dissolving but is rather being “right-sized” and “up-skilled.” The implications for global policy are significant: Washington must accept a degree of Indian strategic autonomy that includes a persistent, albeit evolved, defense reliance on Moscow. For India, the challenge remains ensuring supply chain reliability for legacy equipment while navigating the diplomatic tightrope. The BrahMos model—defined by equal stakes, technology transfer, and export rights—is identified as the only sustainable template for future projects. The document concludes that Chemezov‘s offer is credible not as a return to the bulk-buying era of the Soviet Union, but as a focused invitation for joint development in strategic niches where India cannot yet walk alone. The resilience of this partnership serves as a geopolitical stabilizer in Eurasia, preventing a total Russian drift toward China and providing India with the strategic leverage necessary to maintain a multipolar balance of power in the Indo-Pacific.

The Strategic Pivot: From Buyer-Seller to Joint Production Sovereignty
The definitive articulation of the modern Russia-India defense partnership emerged not from the corridors of the Kremlin or South Block, but on the sidelines of the Dubai Airshow in November 2025, where the geopolitical realities of Eurasia intersected with New Delhi’s industrial ambitions. Sergey Chemezov, the Director General of Rostec, the state-owned defense conglomerate that controls the vast majority of Russia’s military-industrial complex, delivered a statement that functioned less as a sales pitch and more as a strategic concession to India‘s rising stature. By asserting that Russia is prepared to supply “whatever India requires” and, crucially, support the “localization of high-value components,” Chemezov acknowledged a fundamental structural shift: the era of off-the-shelf procurement is irrevocably closed. The ANI News report, “‘Whatever India requires, we are here to support’: Rostec CEO affirms support for India’s defence needs, November 2025,” captures this pivotal moment where Moscow publicly accepted its new role—not as a patron, but as a junior partner in India‘s quest for strategic autonomy.
This chapter analyzes the empirical dimensions of this pivot, moving beyond diplomatic rhetoric to examine the hard data of arms transfers, industrial output, and joint venture performance. The transformation is driven by India‘s “Atmanirbhar Bharat” (Self-Reliant India) initiative, which has fundamentally altered the terms of engagement for all foreign original equipment manufacturers (OEMs). For Russia, a supplier historically accustomed to monopoly status in the Indian market, this has necessitated a radical business model re-engineering. The evidence suggests that while the volume of direct imports has declined—a trend often potentialy misinterpreted by Western observers as a decoupling—the depth of technological integration has intensified in specific, high-value sectors where Western alternatives remain inaccessible or prohibitively restricted by end-use monitoring.
The Statistical Reality: Deconstructing the Decline
To understand the magnitude of this shift, one must first confront the data presented by the Stockholm International Peace Research Institute (SIPRI). The SIPRI report “Trends in International Arms Transfers, 2024,” released in March 2025, provides a quantitative baseline. It records a stark contraction in Russia’s share of India’s arms imports, which fell by approximately 34% in the five-year block of 2019–2023 compared to 2014–2018. This statistical drop is not merely a function of Russia’s supply constraints due to the war in Ukraine, but a deliberate policy outcome of New Delhi’s diversification strategy.
However, a granular analysis of the SIPRI dataset reveals a counter-intuitive trend: while the intake of complete platforms (such as aircraft and tanks) has slowed, the transfer of essential components, engines, and sub-assemblies for license production has remained robust. The Ministry of Defence India’s “Annual Report 2023-24” corroborates this, noting that the sustainment of the Indian Armed Forces‘ vast inventory—comprising over 270 Su-30MKI fighters and 1,000 T-90S tanks—requires an uninterrupted flow of Russian spares. The pivot, therefore, is not a cessation of trade but a migration from “Buy Global” to “Make in India” categories. The SIPRI data underscores that despite the decline, Russia remains India‘s primary supplier of strategic weapons systems, accounting for a critical portion of its area-denial and offensive strike capabilities.
The Policy Architecture: Indigenisation as a Geopolitical Filter
The structural engine driving this transition is the Ministry of Defence India‘s rigorous implementation of “Positive Indigenisation Lists” (PILs). These lists, notified by the Department of Military Affairs (DMA), place an absolute embargo on the import of specific weapons systems and components after a defined cutoff date, forcing the armed forces to procure from domestic sources. The Press Information Bureau’s release, “Make in India Powers Defence Growth, March 2025,” highlights that over 5,500 items have been notified across five PILs, with 3,000 already indigenized as of February 2025.
This policy has a disproportionate impact on Russian platforms, which constitute the bulk of legacy systems. For instance, the 5th Positive Indigenisation List, detailed on the Department of Defence Production‘s portal “DDPMoD: Home,” includes critical Line Replacement Units (LRUs) for the T-90S tank and the Su-30MKI fighter. By banning the direct import of these items, New Delhi has effectively forced Russian OEMs like Uralvagonzavod and United Aircraft Corporation (UAC) to enter into joint ventures or technology transfer agreements with Indian firms to retain their market share.
The success of this policy is reflected in the macro-economic data. The Ministry of Defence India reported that defense production reached a record ₹1.27 lakh crore ($15 billion) in FY 2023-24, a 174% increase since 2014-15. This surge is powered by the domestic manufacturing of components that were previously imported from Moscow. The Rostec leadership’s willingness to “support localization” is thus a direct response to this regulatory coercion; they must localize or lose the contract entirely to Indian private sector entities like Tata Advanced Systems or Bharat Forge, who are increasingly capable of reverse-engineering or developing alternative solutions.
The AK-203 Case Study: From Delays to “Sher” Sovereignty
The most tangible manifestation of this “joint production sovereignty” is the Indo-Russian Rifles Private Limited (IRRPL) facility in Korwa, Amethi. Established as a joint venture between the Ordnance Factory Board (now corporatized as Advanced Weapons and Equipment India Limited and Munitions India Limited) and Russian entities Rosoboronexport and Kalashnikov Concern, this project was designed to replace the Indian Army’s aging INSAS rifles with the modern AK-203.
Initially plagued by pricing disputes and royalty negotiation delays, the project has achieved a remarkable turnaround in 2024–2025. A report by the Deccan Chronicle, “India to Roll Out Fully Indigenous AK-203s by End of 2025, July 2025,” confirms that the facility delivered 35,000 rifles in 2024 and is on track to achieve 100% indigenisation by December 2025. The significance of this milestone cannot be overstated. Achieving 100% indigenous content means that every spring, barrel, and receiver is manufactured in India, eliminating the supply chain vulnerability associated with Russian imports.
Furthermore, the rebranding of the fully indigenized rifle as the “Sher” (Lion) symbolizes the shift in ownership. While the design remains Kalashnikov‘s intellectual property, the production capability is now effectively Indian. The IRRPL model—where India holds a 50.5% controlling stake—serves as a template for future infantry programs. It demonstrates that New Delhi can leverage the Russian brand and design pedigree while ensuring that the industrial value add remains within the domestic economy. The aggressive timeline, which anticipates the delivery of 600,000 units by 2030 (22 months ahead of schedule), validates the efficiency of the corporatized JV model over the erstwhile direct license-production agreements.
The BrahMos Paradigm: A Model for Global Export
If the AK-203 represents the struggle for indigenization, the BrahMos Aerospace joint venture represents the pinnacle of “Joint Production Sovereignty” and its evolution into export capability. A joint venture between India‘s Defence Research and Development Organisation (DRDO) and Russia‘s NPO Mashinostroyenia, BrahMos has successfully developed the world’s fastest supersonic cruise missile. Unlike other programs where India is the sole customer, BrahMos has evolved into a global export product, insulating it partially from Western sanctions through its high indigenous content (over 75%).
In October 2025, BrahMos Aerospace cemented its status as a major global player. As reported by Defence Industry Europe in “India’s BrahMos Aerospace signs $482 million missile export deals with two undisclosed nations, October 2025,” the JV secured contracts worth $482 million. This follows the successful delivery of the shore-based anti-ship missile system to the Philippines in April 2024, a deal valued at $375 million.
These exports are critical for the Russia-India partnership for two reasons. First, they generate revenue that can be reinvested into R&D for next-generation systems like the BrahMos-NG (Next Generation) and hypersonic variants, reducing the financial burden on the Indian exchequer. Second, they demonstrate that Russian technology, when refined and integrated by Indian systems engineering, remains globally competitive. The CARE Ratings report on BrahMos Aerospace, “BrahMos Aerospace Private Limited – CARE Ratings, October 2025,” highlights the financial health of the JV, noting a 38% increase in total operating income to ₹4,819 crore in FY25. This financial autonomy distinguishes BrahMos from other state-run defense enterprises, proving that the JV model can be commercially viable on the international market.
The High-Tech Horizon: Su-57 and Beyond
The implications of Chemezov’s offer extend beyond rifles and cruise missiles to the cutting edge of aerospace technology. The ANI News report regarding the Dubai Airshow 2025 confirms that Russia has formally offered the Su-57 fifth-generation fighter to India, explicitly including “technology transfer” and “technological learning” of critical systems such as AESA radars and engines. This offer addresses the core grievance that led India to withdraw from the earlier Fifth Generation Fighter Aircraft (FGFA) program: the refusal of Russia to share source codes and critical design data.
In 2025, facing a prolonged war and isolation from Western markets, Moscow’s calculus has shifted. It needs India not just as a buyer, but as a co-developer to amortize the costs of its own military modernization. For India, the offer presents a dilemma and an opportunity. While the IAF is committed to the indigenous AMCA (Advanced Medium Combat Aircraft) program, the developmental timelines for AMCA are long. A joint production arrangement for the Su-57, or its technologies, could serve as an interim solution or a technological accelerator for the AMCA.
The transformation of the Russia-India defense relationship in 2025 is characterized by a move away from the passive “buyer-seller” dynamic to an active “collaborative sovereignty.” The data from SIPRI and the Ministry of Defence India confirms that while the volume of traditional imports has fallen, the strategic value of the partnership has migrated to the industrial domain. Russia has accepted that to remain relevant in New Delhi, it must become a stakeholder in India‘s manufacturing ecosystem.
The success of IRRPL and BrahMos proves that this model is viable. It allows India to maintain the operational readiness of its Russian-origin platforms while systematically building the industrial base required to eventually replace them or upgrade them indigenously. Chemezov’s declaration at Dubai is thus verified by the ground reality: Moscow is here to support, but strictly on New Delhi’s terms. This “Strategic Pivot” effectively insulates India from the worst effects of supply chain disruptions and sanctions, creating a resilient, sovereign defense posture that leverages Russian legacy for Indian future.
Aerospace Dominance: The Su-30MKI Upgrades and S-400 Integration
The aerospace domain constitutes the kinetic nucleus of the Russia–India defense partnership, representing the highest density of financial investment and technological dependency. As of October 2025, the Indian Air Force (IAF) operates in a volatile security environment defined by the dual-front threat of the People’s Liberation Army Air Force (PLAAF) and the Pakistan Air Force (PAF). To address the widening asymmetry in fifth-generation capabilities—driven by China‘s deployment of the J-20—New Delhi has executed a bifurcation strategy: accelerating indigenous stealth programs while concurrently executing a comprehensive “super-hardening” of its Russian-origin legacy fleet. This chapter strictly analyzes the technical and industrial execution of the Su-30MKI “Super Sukhoi” upgrade program and the operational integration of the S-400 Triumf air defense system, utilizing exclusively verified data from government and strategic sources.
The Su-30MKI Modernization: Industrial and Technical Sovereignty
The Su-30MKI Flanker-H remains the backbone of the IAF’s combat potential, comprising 12 squadrons with 259 active airframes (attrition adjusted). The strategic imperative in 2025 is no longer acquisition, but obsolescence management and capability enhancement through the “Super Sukhoi” program. This initiative is not merely a retrofit; it is a fundamental re-architecture of the aircraft’s avionics and sensor suite, transitioning from Russian proprietary standards to an open-architecture model that accommodates Indian weapons and sensors.
The AL-31FP Engine Contract: Securing the Powerplant
The foundational step for this modernization was solidified on September 2, 2024, when the Cabinet Committee on Security (CCS), chaired by Prime Minister Narendra Modi, approved a critical procurement proposal. The Press Information Bureau (PIB) release, “Cabinet approves proposal for procurement of 240 Aero-engines (AL-31FP) for Su-30 MKI aircraft, September 2024,” details the authorization for the purchase of 240 AL-31FP aero-engines from Hindustan Aeronautics Limited (HAL) at a cost of over ₹26,000 crore ($3.1 billion).
This contract is pivotal for three verifiable reasons:
- Indigenous Content Mandate: The PIB document explicitly states that the engines will contain an indigenous content of over 54%, manufactured at the Koraput Division of HAL. This reduces dependency on the United Engine Corporation (UEC) of Russia for critical hot-section components, mitigating supply chain risks arising from the Ukraine conflict.
- Delivery Timeline: The delivery schedule is fixed for eight years, commencing in 2025, ensuring the operational availability of the Su-30MKI fleet through 2050.
- Sovereign Maintenance: By localizing the manufacturing of key sub-assemblies, India retains the ability to overhaul these engines without shipping them to Ufa, Russia, a logistical bottleneck that plagued the IAF in previous decades.
Radar and Avionics: The Virupaksha Transition
The most significant technological leap in the “Super Sukhoi” upgrade is the replacement of the legacy N011M Bars Passive Electronically Scanned Array (PESA) radar. The Ministry of Defence India has authorized the integration of the indigenous “Virupaksha” Active Electronically Scanned Array (AESA) radar. While official technical specifications remain classified, the Defence Research and Development Organisation (DRDO) annual reports indicate that the Virupaksha is a scaled-up derivative of the Uttam AESA radar developed for the Tejas Mk1A.
This transition alters the strategic calculus in the region. The N011M Bars operates on older processing architectures susceptible to modern Digital Radio Frequency Memory (DRFM) jamming employed by Chinese electronic warfare suites. The Virupaksha AESA provides:
- Low Probability of Intercept (LPI): Enabling the Su-30MKI to track targets without alerting enemy Radar Warning Receivers (RWR) as easily as the high-energy PESA.
- Simultaneous Air-to-Air and Air-to-Ground Modes: A capability confirmed in DRDO’s broader AESA development roadmap.
- Long-Range Detection: Extending the detection envelope to match or exceed the PLAAF’s J-10C and J-16 radars.
Weaponization: Decoupling from Russian Inventories
The upgrade program aggressively decouples the fire-control system from exclusively Russian munitions. While the R-77 and R-73 missiles remain in inventory, the primary loadout is shifting to indigenous assets. The Ministry of Defence India’s “Year End Review 2024: Department of Defence Production,” (data valid as of December 2024) confirms the successful integration and mass production of the Astra Mk1 Beyond Visual Range (BVR) air-to-air missile.
The integration of the Astra Mk1 (range 110 km+) and the upcoming Astra Mk2 (range 160 km+) on the Su-30MKI eliminates the reliance on the export-controlled RVV-SD (Russian R-77 variant). Furthermore, the integration of the New Generation Anti-Radiation Missile (NGARM), or “Rudram-1,” grants the Su-30MKI a sovereign Suppression of Enemy Air Defenses (SEAD) capability, crucial for neutralizing Chinese HQ-9 air defense batteries. This “weaponization sovereignty” ensures that in a conflict scenario, New Delhi is not beholden to Moscow for missile replenishment, addressing the “use restrictions” often associated with imported guided weapons.
The S-400 Triumf: Deployment and Strategic Friction
If the Su-30MKI represents the sword of Indian aerospace power, the S-400 Triumf (NATO reporting name: SA-21 Growler) is the shield. The $5.43 billion deal signed in 2018 for five regiments remains the single most contentious and significant element of the bilateral relationship, triggering friction with the United States under the Countering America’s Adversaries Through Sanctions Act (CAATSA).
Delivery Status and Delays
As of October 2025, the delivery schedule of the S-400 has experienced verified deviations due to the ongoing war in Ukraine. According to the Stockholm International Peace Research Institute (SIPRI) “Trends in International Arms Transfers, 2024,” Russia had delivered three complete regiments by the end of 2023. The remaining two regiments, originally scheduled for delivery by early 2024, were rescheduled.
Official statements from the IAF leadership, referenced in Ministry of Defence briefings, confirm that the final two squadrons are expected by 2026. This delay, while operationally sub-optimal, has not resulted in a cancellation. New Delhi has utilized this interim period to operationalize the first three squadrons, strategically positioning them to cover the Ladakh sector (facing China) and the Punjab sector (facing Pakistan). The “viscous” nature of the delivery—where components arrive piecemeal rather than as monolithic units—allows India to conduct acceptance trials and training incrementally.
The CAATSA Conundrum and Strategic Autonomy
The procurement of the S-400 technically triggers secondary sanctions under Section 231 of CAATSA. However, Washington has refrained from applying these sanctions to India, a decision driven by the geopolitical necessity of the Indo-Pacific strategy. The Congressional Research Service (CRS) report “India-U.S. Relations, September 2024” explicitly notes the Biden Administration’s prioritization of the strategic partnership over punitive measures regarding the S-400.
The CRS analysis highlights that applying sanctions would severely damage the Quad framework and push New Delhi closer to Moscow—the exact outcome CAATSA aims to prevent. Consequently, the S-400 stands as a symbol of Indian strategic autonomy; India successfully procured a major strategic system from a US adversary without incurring US penalties, establishing a precedent that defense procurement decisions are sovereign and immune to third-party vetoes.
Technological Integration: The IACCS Challenge
The operational efficacy of the S-400 depends on its integration into the IAF’s Integrated Air Command and Control System (IACCS). This presents a complex engineering challenge: interfacing Russian data links with an Indian network that increasingly hosts Western platforms (like the Rafale, P-8I Poseidon, and C-130J).
While Russia provides the S-400 with its proprietary command posts (55K6E), India has mandated the development of indigenous interface modules. The Bharat Electronics Limited (BEL) “Annual Report 2023-24” lists “Air Defence Control & Reporting Systems” among its key deliverables, indicating progress in creating the middleware necessary to fuse S-400 sensor data with the broader IACCS picture. This integration allows the S-400’s massive tracking radar (91N6E Big Bird) to serve as a strategic surveillance node for the entire IAF, not just for its own interceptors.
The Hybrid Aerospace Architecture
The aerospace domain in 2025 demonstrates a sophisticated hybrid architecture. India is not replacing Russian hardware with Western hardware in a zero-sum game; rather, it is upgrading Russian platforms with Indian avionics and weapons to create a distinct “Indo-Russian” capability tier. The Su-30MKI, powered by locally produced AL-31FP engines and directed by the Virupaksha radar, will remain the mass-maneuver force of the IAF well into the 2040s. Simultaneously, the S-400 provides the anti-access/area-denial (A2/AD) umbrella under which indigenous systems like the Tejas Mk2 and AMCA can be developed.
This approach maximizes return on investment for the billions already sunk into the Russian ecosystem while neutralizing the geopolitical risks of dependency. By controlling the “brain” (avionics/radar) and the “claws” (missiles) of the aircraft, India ensures that Moscow supplies the hardware, but New Delhi controls the mission.
Naval and Land Warfare: Submarines, Frigates, and Armoured Resilience
The maritime and terrestrial domains of the Russia-India defense partnership are currently defined by a stark dichotomy: while the surface fleet witnesses the final curtain call of direct imports, the underwater and armoured sectors are undergoing a forced evolution driven by obsolescence and the imperatives of high-altitude warfare. As of November 2025, the strategic conversation has moved beyond simple acquisition to the complex engineering of life-extensions and the integration of hybrid capabilities. The commissioning of the Grigorovich-class frigates marks the end of an era, while the delays in nuclear submarine leases and the aggressive up-gunning of the T-90S tank fleet signal a new phase of pragmatic dependency.
The Final Frigates: Tushil, Tamal, and the Zorya Workaround
The commissioning of INS Tushil at the Yantar Shipyard in Kaliningrad on December 9, 2024, stands as a watershed moment in Indian naval history. As reported by The Hindu in “Tamal, India’s last imported warship, likely to be commissioned in June, February 2025,” INS Tushil arrived at its home port of Karwar on February 14, 2025, after navigating a geopolitical minefield that threatened to derail the entire project. The vessel, the first of two directly imported stealth frigates under the 2016 Inter-Governmental Agreement, represents the triumph of logistical ingenuity over sanctions.
The core challenge lay in the propulsion system: the M7N.1E gas turbine plant, manufactured by Zorya-Mashproekt in Ukraine. Following the outbreak of hostilities in 2014 and the full-scale invasion in 2022, the supply chain between Russia and Ukraine was severed. India stepped in to directly procure the engines from Ukraine and transport them to Russia for installation—a diplomatic tightrope walk that allowed the project to proceed. INS Tamal, the second and final ship of this tranche, is scheduled for commissioning on July 1, 2025.
However, the significance of INS Tamal extends beyond its sensors and weapons; it is explicitly identified by the Indian Navy as the “last warship to be inducted from a foreign source.” Future acquisitions, including the remaining two frigates of the class, are being constructed at Goa Shipyard Limited (GSL) with Russian technical assistance, adhering to the “Make in India” mandate. This transition confirms that while Russian design philosophy—prized for its ruggedness and missile saturation capability—remains central to Indian naval doctrine, the hull fabrication and system integration have permanently shifted to Indian yards.
The Submarine Gap: Nuclear Leases and the P-75I Exit
Beneath the surface, the partnership faces its most acute stress test. The Indian Navy’s conventional submarine fleet, anchored by the aging Kilo-class (Sindhughosh-class) vessels, is shrinking. The Project 75 (India) (P-75I) tender, intended to build six next-generation submarines with Air-Independent Propulsion (AIP), has seen the exit of Russia. As confirmed by Naval News in “TKMS enters contract negotiations with MDL for P75(I) program, September 2025,” the German firm ThyssenKrupp Marine Systems (TKMS) has entered exclusive negotiations with Mazagon Dock Shipbuilders Limited (MDL). Russia’s Rubin Design Bureau, unable to meet the strict technical requirements for a proven sea-operational AIP system, is effectively out of the running for India’s future conventional force.
To mitigate this capability gap, New Delhi has doubled down on the nuclear domain, where Russia remains the sole provider of leasing options. The lease of the Akula-1 class nuclear-powered attack submarine (SSN), designated Chakra III, has encountered significant delays. Originally scheduled for delivery in 2025, the timeline has slipped. Raksha Anirveda reports in “Strategic Interim Solution: India to Lease Russia’s ‘Stealth’ Nuclear Attack Submarines, November 2025” that the vessel, currently undergoing extensive modernization at a Russian shipyard, is now expected by 2028.
The delay is attributed to the “technical complexities” of stripping the hull of obsolete Soviet-era wiring and installing Indian communication and sonar suites, exacerbated by labor shortages in Russia‘s defense sector. To compensate, Moscow has reportedly offered a “stopgap” lease of a second Akula-class hull (K-519 Iribis), though New Delhi remains cautious. The critical value of the Chakra III deal lies not just in the platform, but in the training it provides for the crews who will eventually man India‘s indigenous Project 75 Alpha SSNs. Russia’s willingness to share nuclear propulsion operational know-how—a technology Washington and Paris guard jealously—ensures its continued relevance in India‘s strategic calculus, even as the conventional market share erodes.
Land Warfare: The High-Altitude Up-Gun
In the terrestrial domain, the Indian Army’s reliance on Russian armour remains absolute but is undergoing a radical qualitative upgrade. The T-90S Bhishma Main Battle Tank (MBT), numbering over 1,000 units, faces a new operational reality: the rarefied air of Eastern Ladakh. The existing 1,000 horsepower (HP) V-92S2 engines have struggled with power derating at altitudes above 15,000 feet, a limitation exposed during the standoff with China.
On March 20, 2025, the Defence Acquisition Council (DAC), chaired by Defence Minister Rajnath Singh, cleared a critical proposal to address this vulnerability. The Press Information Bureau (PIB) release, “DAC clears capital acquisition proposals worth over Rs 54,000 crore… Procurement of 1350 HP engines for T-90 tanks, March 2025,” confirms the Acceptance of Necessity (AoN) for the procurement of 1,350 HP engines. This upgrade is not a mere replacement; it fundamentally alters the power-to-weight ratio of the T-90S, restoring its mobility in alpine terrain.
The engine upgrade is complemented by a renewed focus on firepower. On November 13, 2025, the Ministry of Defence finalized a contract with Bharat Dynamics Limited (BDL) for the supply of Invar Anti-Tank Guided Missiles (ATGMs). As detailed by Army Technology in “India places $236.4m order for Invar anti-tank missiles with BDL, November 2025,” this $236.4 million deal ensures that the T-90S fleet retains its lethal edge. The Invar missile, capable of engaging targets at 5 kilometers, provides the T-90S with a standoff range superior to most adversary tanks. Crucially, these missiles are being manufactured under license by BDL, ensuring that ammunition stocks are immune to external supply shocks.
The Shift from Sprut to Zorawar
A notable casualty of the “Make in India” policy in the land domain is the Russian Sprut-SDM1 light tank. Following the 2020 border clashes, India initially considered an emergency purchase of the Sprut to counter China‘s Type 15 light tanks. However, by 2025, this requirement has been subsumed by the indigenous Project Zorawar. The absence of any new contract for the Sprut in the 2024-25 fiscal year confirms that New Delhi has opted to develop its own light tank platform, likely utilizing the DRDO–L&T chassis but potentially integrating Russian fire control concepts or gun barrels where indigenous options are not yet mature.
The Architecture of Resilience
The 2025 naval and land landscape reveals a partnership that has shed its “supermarket” characteristics in favor of targeted, high-stakes engineering collaboration. The Indian Navy accepts the delays in the Chakra III because the capability it offers—nuclear underwater endurance—is irreplaceable. The Indian Army invests in Russian-designed 1,350 HP engines and Invar missiles because the T-90S chassis remains the most viable platform for the Himalayan frontier. Russia’s role has thus evolved from being the primary architect of India’s military machine to being its specialized structural engineer, reinforcing the critical load-bearing pillars—nuclear propulsion and armoured mobility—while the facade becomes increasingly Indian.
The Economic Architecture: Sanctions, Vostro Accounts, and Trade Flows
The sustainability of the Russia-India defense partnership in 2025 is no longer determined solely by technical compatibility or geopolitical intent, but by a complex, improvised financial architecture designed to circumvent the US Dollar hegemony. As the West tightened its stranglehold on Moscow’s access to the SWIFT messaging system, New Delhi and Moscow constructed a parallel economic ecosystem. This chapter dissects the mechanics of this arrangement, moving from the macro-level trade imbalance to the micro-level banking protocols that allow the Indian Armed Forces to pay for S-400 batteries using funds generated from Russian crude oil sales.
The Trade Imbalance: A Liquidity Trap
To understand the payment crisis, one must first analyze the sheer volume of bilateral trade, which has undergone a seismic shift. According to the Embassy of India, Moscow’s brief “India-Russia Economic Relations, August 2025,” bilateral trade reached an unprecedented $68.7 billion in FY 2024-25, a nearly six-fold increase from pre-conflict levels. However, this growth is asymmetric. India’s imports, dominated by discounted crude oil and fertilizers, stood at $63.84 billion, while exports languished at $4.88 billion.
This asymmetry created a “Liquidity Trap.” Russian exporters, primarily state-owned energy giants like Rosneft and Gazprom, accumulated billions of Indian Rupees (INR) in their Special Rupee Vostro Accounts (SRVA) in Indian banks. Since the Rupee is not fully convertible, Russia faced a dilemma: it held vast cash reserves that it could not repatriate to Moscow or convert into US Dollars without triggering sanctions alerts. This “Rupee Trap” initially paralyzed defense payments, leading to the delays in S-400 deliveries seen in 2023-24.
The SRVA Mechanism: The Financial Bypass
The solution to this impasse was the operationalization of the Special Rupee Vostro Account (SRVA) mechanism, authorized by the Reserve Bank of India (RBI). As detailed in the RBI’s “Master Direction – International Trade Settlement in Indian Rupees, October 2025,” this framework allows authorized dealer banks in India to open accounts for correspondent banks in Russia.
In practice, this works as a closed-loop system. When an Indian refinery buys Russian oil, it deposits Rupees into the SRVA held by a Russian bank (e.g., Sberbank or VTB) at an Indian partner bank (e.g., UCO Bank). Instead of attempting to move this money back to Russia, Moscow is now utilizing these funds within India. The Sberbank India portal, “Sberbank Branch in India: Corporate Business, November 2025,” confirms that the bank is actively facilitating “payment for education,” “investments,” and “local vendor payments” using these accumulated funds.
Breaking the Logjam: Sovereign Investment as Payment
By late 2025, the “Rupee Trap” has been effectively neutralized by converting the currency issue into an investment opportunity. A pivotal development reported by The Economic Times in “RBI allows investment of surplus rupee balances in special vostro accounts into Govt Securities, August 2025” reveals that the RBI amended the Foreign Exchange Management Act (FEMA) regulations to allow SRVA holders to invest surplus balances in Government Securities (G-Secs) and Treasury Bills.
This regulatory change fundamentally altered the defense payment landscape. Russia is now using its oil revenue to purchase Indian sovereign debt. These funds, now technically “invested” in India, are liquid enough to be redirected to pay Indian defense contractors. For instance, the Hindustan Times report “Russia tackles accumulation of rupees through investments in India, October 2025” confirms that the logjam over defense payments has been broken. The funds for the S-400 and frigates are being settled domestically: Russia pays Indian shipyards and missile integrators (like BrahMos Aerospace) using the Rupees it earned from oil, effectively engaging in a form of sophisticated barter where energy funds military production.
The S-400 Resolution and Future Risks
The direct result of this financial re-engineering is the resumption of strategic deliveries. As noted in Chapter 2, the remaining S-400 squadrons are back on schedule. The United24 Media report “Despite Delays, India Expands S-400 Arsenal With New $1.2B Missile Order, October 2025” highlights that India is not only receiving the backlog but placing new orders for missiles worth $1.2 billion. This would be impossible without a functional, sanction-proof payment tunnel.
However, the architecture faces a new, existential threat as of November 2025. The return of aggressive sanctions enforcement by the US administration has targeted the “shadow fleet” of tankers carrying Russian oil. The Times of India article “Trump sanctions a ‘crude’ shock! Russia oil shipments to India drop by 66%, November 19, 2025” reports a sudden, precipitous drop in oil volumes. If Russian oil revenues in India collapse, the Rupee liquidity drying up will once again stall defense payments, proving that the military partnership is now entirely leveraged on the energy trade.
The Internalized Defense Economy
The economic architecture of the Russia-India partnership has evolved from a simple cross-border transfer of hard currency to an internalized defense economy. Russia has effectively become a domestic investor in India‘s defense industrial base, funding production lines with Rupees generated from local sales. While this defeats the SWIFT ban, it binds the security of India‘s borders to the continued flow of Russian oil. The SRVA mechanism is a brilliant tactical workaround, but the events of November 2025 demonstrate its vulnerability to external shocks in the global energy market.
Geopolitical Implications: Balancing the US-China-Russia Triangle
As of November 2025, the geopolitical architecture of Eurasia is defined by a precarious equilibrium. India’s strategic posture, often described as “multi-alignment,” faces its most severe stress test as the divergence between the United States, China, and Russia hardens into rigid blocs. The Russia-India partnership, while historically rooted in bilateral defense and energy needs, now functions as a critical counter-weight in New Delhi’s grand strategy to prevent a total Sino-Russian consolidation that would encircle the subcontinent. This chapter analyzes the geopolitical mechanics of this triangular balance, examining how New Delhi leverages its relationship with Moscow to manage Beijing’s aggression while maintaining its indispensability to Washington.
The China Factor: The “No Limits” Wedge
The defining variable in the 2025 calculus is the depth of the Russia-China “no limits” partnership. For New Delhi, the nightmare scenario is a Moscow fully subservient to Beijing, transforming Russia from a trusted partner into a potential spoiler in the Himalayas. However, verified strategic assessments suggest a more nuanced reality. The CNA report, “Russia and China Have Drawn Closer: Three Ways to Wedge Them Apart, August 2025,” posits that while the Moscow-Beijing axis has deepened militarily—with trade turnover exceeding $250 billion—Russia remains wary of becoming a raw material appendage to China.
This latent friction is India’s strategic opportunity. By maintaining high-volume trade and defense ties, India provides Russia with a necessary diversification option, preventing total dependence on China. The Ministry of External Affairs India (MEA) articulated this logic implicitly in the “Leaders’ Joint Statement on the development of strategic areas of Russia-India economic cooperation for the period up to 2030, July 2024.” The document’s explicit target of $100 billion in bilateral trade by 2030 is not merely an economic goal but a geopolitical instrument to keep Moscow anchored in a multipolar Eurasia rather than a unipolar Chinese sphere.
Furthermore, the East Asia Forum analysis, “Is China and Russia’s relationship too close for comfort?, September 2025,” highlights that Russia has quietly continued to supply India with offensive platforms (like the S-400 and BrahMos inputs) that directly counter Chinese capabilities. This behavior contradicts the “junior partner” narrative, suggesting that Moscow views a strong India as a necessary check on Chinese dominance in the Global South.
The US Factor: Managing the “CAATSA” Exception
The most delicate wire New Delhi walks is with Washington. The United States views Russia as an acute threat, yet it views China as the systemic pacing challenge. Consequently, US policy toward India’s Russian ties has evolved from punitive threats to grudging acceptance of “Strategic Autonomy.” The Carnegie Endowment for International Peace report, “The Impact of U.S. Sanctions and Tariffs on India’s Russian Oil Imports, November 2025,” documents the friction points, specifically the August 2025 tariff escalations and secondary sanctions on shipping entities.
However, the underlying strategic logic remains intact: Washington requires India to be a net security provider in the Indo-Pacific. A weakened India, deprived of Russian spares for its Su-30MKI fleet or T-90S tanks, would be less capable of deterring China along the Line of Actual Control (LAC). This realization has led to a de facto waiver of the Countering America’s Adversaries Through Sanctions Act (CAATSA). The Congressional Research Service (CRS) in its brief “India-U.S. Relations, September 2024” (updated contextually in 2025) notes that despite the sanctions rhetoric, defense technology cooperation under the Initiative on Critical and Emerging Technology (iCET) has accelerated, proving that the US-India partnership has “de-hyphenated” from the Russia issue.
The Global South and Multipolarity: The BRICS Catalyst
The third vertex of this triangle is the Global South, where India and Russia cooperate to shape a non-Western (but not anti-Western) order. The XVI BRICS Summit in Kazan, Russia (October 2024), served as a platform for this alignment. Prime Minister Modi’s presence and the subsequent expansion of BRICS demonstrated India’s commitment to multipolarity.
The Observer Research Foundation (ORF) assessment, “Politics and Protectionism: Decoding the Challenges to India-Sri Lanka Connectivity, November 2025,” while focused on regional connectivity, contextualizes this broader trend: India is actively building alternative supply chains and payment corridors (like the INSTC and the Chennai-Vladivostok Maritime Corridor) that bypass Western choke points. This infrastructure aligns with Russia’s “Pivot to the East” and India’s “Act East” policy, creating a physical lattice that supports their geopolitical convergence.
The “Rasputitsa” of Diplomacy
In 2025, India’s balancing act resembles the navigation of the Rasputitsa (the mud season)—slow, deliberate, and fraught with the risk of getting stuck. The evidence indicates that New Delhi has successfully prevented a rupture with Washington while deepening the industrial embrace of Moscow. The Russia-India partnership acts as a stabilizer in the US-China-Russia triangle: it prevents Russia from falling completely into China‘s orbit and provides the US with a partner in Asia that is capable of defending itself. As long as China remains the primary threat to Indian sovereignty, Moscow will remain an essential, albeit complicated, ally. The “Strategic Pivot” described in Chapter 1 is thus not just a defense industrial policy; it is the supreme act of Indian geopolitical survival.
