Russia’s RD-93 Engine Sale to Pakistan Could Backfire — and Strengthen India’s Strategic Edge, Say Russian Experts

(DEFENCE SECURITY ASIA) — Russian defence experts said the reported sale of RD-93 engines to Pakistan for use in its JF-17 fighter jets could, in fact, work in India’s favour, according to a report by the Press Trust of India (PTI).

The remarks come amid sharp criticism in New Delhi over Moscow’s alleged military cooperation with Islamabad, reviving concerns that Russia is drifting away from its long-standing strategic partnership with India.

 

It must be noted, however, that there has been no official confirmation from Moscow that Russia has agreed to supply Pakistan with the engines.

“[However] if reports about Russia providing engines for the JF-17 are correct, it actually benefits India in two ways,” said Pyotr Topychkanov, head of the Section on New Challenges in South and Southeast Asia at the Primakov Institute in Moscow.

“Firstly, it shows that China and Pakistan have not yet managed to replace the Russian-origin engine. Secondly, the new aircraft will be familiar and predictable to India, especially since they share the same engine and India observed the JF-17’s operational use during the May 2025 crisis (Operation Sindoor),” he told PTI.

Topychkanov called the criticism of the Indian government “unjustified,” saying the development must be viewed in the context of long-standing defence relations between Moscow and New Delhi that continue to underpin a large portion of India’s military inventory.

He also recalled that China had earlier requested Russia to supply RD-93 engines for its FC-17 aircraft as a temporary measure and that the issue of these engines potentially reaching Pakistan was already debated in India during the governments of Atal Bihari Vajpayee and Dr. Manmohan Singh.

In addition to Topychkanov’s remarks, Russian analysts noted that the RD-93 engine export underscores Moscow’s enduring leverage in South Asia’s aerospace balance, as both India and Pakistan remain dependent on legacy Soviet-era propulsion technologies for their front-line fighter fleets.

They emphasized that India’s familiarity with the RD-33 and RD-93 family—spanning decades of maintenance, overhaul, and testing—provides its engineers and air defence planners with valuable data on engine signatures, acoustic patterns, and infrared emissions, allowing Indian sensors and missiles to better track and engage Pakistan’s JF-17s during combat operations.

Furthermore, experts added that the continued Russian supply of RD-93 engines reflects Moscow’s pragmatic attempt to maintain its industrial production lines under Western sanctions, while simultaneously ensuring that both South Asian rivals remain tethered to Russian aerospace technology, preserving Moscow’s strategic influence over the region’s evolving airpower equation.

MOSCOW’S HISTORICAL CONTEXT AND TECHNOLOGY TRANSFER

Another Russian expert, who declined to be identified, said he remembered those earlier discussions and emphasized that Moscow had assured New Delhi that the RD-93 deal with China was purely commercial and did not involve any transfer of technology (ToT) to Pakistan.

“Moscow convinced New Delhi that the RD-93 deal was commercial in nature. India, in contrast, received the license for a much superior RD-33 engine under a full technology transfer agreement,” he said.

The RD-93 engine, developed and produced by UEC-Klimov in St. Petersburg, is a derivative of the RD-33 engine that powers India’s MiG-29 Fulcrum fleet.

While the RD-93 offers higher thrust—around 8,300 kgf—it comes with a shorter service life of approximately 2,200 hours, compared with the RD-33’s 4,000 hours used by the Indian Air Force.

Since the early 2000s, Russia has supplied fully assembled RD-93 engines to Pakistan through a trilateral export arrangement with China, which initially requested them for the FC-1 Xiaolong, the Chinese designation of the JF-17 Thunder.

Today, that cooperation has evolved into a more direct relationship, with reports suggesting that Pakistan is now seeking the upgraded RD-93MA variant, a next-generation derivative that remains under development and testing.

POLITICAL CONTROVERSY IN INDIA

Reports of renewed RD-93 engine deliveries to Pakistan have sparked political debate in India, exposing divisions between the ruling Bharatiya Janata Party (BJP) and the opposition Congress Party over the direction of India’s foreign policy.

Congress leader Jairam Ramesh questioned why India’s “once most reliable strategic ally” was allegedly supplying key military technology to Pakistan, arguing that such moves undermine India’s security interests.

The BJP, however, dismissed the claims as “reckless information warfare,” accusing the opposition of “amplifying unverified reports” and “choosing the side of the enemy” rather than defending national interests.

BJP leaders further emphasized that India’s defence ties with Russia remain robust, pointing to ongoing deliveries of the S-400 Triumf air defence system, joint work on nuclear submarine leasing, and continued support for India’s Su-30MKI fleet.

Yet, analysts note that even if the reports are true, the development may not be detrimental to India.

As Topychkanov highlighted, “The reported deal would actually benefit India. Firstly, it would show that China and Pakistan have not managed to replace the Russian-origin engine. Secondly, the new aircraft would be familiar and predictable to India.”

SHIFTING ALLIANCES AND STRATEGIC REALIGNMENT

In a broader context, the RD-93 issue is emblematic of Russia’s evolving foreign policy in the post-Ukraine war era.

With Western sanctions choking its access to traditional export markets, Moscow has accelerated defence collaboration with China and Pakistan, both eager to exploit gaps in Western technology flows.

For New Delhi, this represents a major diplomatic test.

Despite being one of Russia’s largest defence customers, India now faces a Moscow that prioritizes economic survival and strategic diversification over loyalty to Cold War-era partnerships.

This shift is visible in Russia’s trilateral alignment with Beijing and Islamabad, an arrangement that allows Moscow to expand its defence export base while simultaneously maintaining leverage in South Asia’s arms market.

The ongoing supply of RD-93 or RD-93MA engines to Pakistan therefore reflects both economic pragmatism and geopolitical opportunism—a recognition by Russia that its long-term interests are increasingly tied to China’s industrial and diplomatic clout.

THE RD-93MA ENGINE: A GAME-CHANGER IN SOUTH ASIA

At the heart of this controversy lies the RD-93MA engine, an advanced derivative of the RD-33 family developed by UEC-Klimov as part of Russia’s modernization of its fighter propulsion portfolio.

The RD-93MA offers enhanced thrust of 9,300 kgf, superior fuel efficiency, digital engine control (FADEC), and greater thermal resilience, enabling the JF-17 Block III to sustain heavier payloads and extended missions.

These improvements translate to tangible combat advantages.

The new engine’s higher thrust-to-weight ratio enhances the aircraft’s climb rate and acceleration, vital for dogfight scenarios and interception missions near the Line of Control (LoC).

Its digital control system reduces pilot workload and improves engine reliability, especially during high-altitude operations over the Himalayas where thinner air and temperature extremes can degrade aircraft performance.

Financially, the RD-93MA’s export price is estimated at USD 3.8 million per unit (approximately RM17.9 million), compared with USD 2.5 million (RM11.8 million) for the earlier RD-93 variant.

Industry sources suggest that a single JF-17 Block III unit, powered by the RD-93MA and integrated with advanced Chinese avionics and PL-15 missiles, now costs around USD 32 million (RM151 million)—making it one of the most cost-effective fourth-generation platforms in the global export market.

PAKISTAN’S AIRPOWER ADVANTAGE AND A2/AD STRATEGY

For Pakistan, the arrival of RD-93MA engines marks a major leap in its airpower modernization effort.

The Pakistan Air Force (PAF) plans to induct at least 62 JF-17 Block III fighters by 2026, forming the backbone of its tactical air fleet alongside older Mirage III/5 and F-16 platforms.

The integration of the RD-93MA engine enhances the JF-17’s ability to carry long-range PL-15 air-to-air missiles, capable of striking targets beyond 150 km, giving Pakistan’s pilots a credible edge in BVR (Beyond Visual Range) engagements.

When combined with modern electronic warfare pods and KLJ-7A AESA radar, the RD-93MA-powered JF-17 significantly strengthens Pakistan’s anti-access/area denial (A2/AD) posture across Kashmir and the western front.

Operationally, the engine’s extended service life and simplified maintenance cycles have reduced the PAF’s dependence on costly overhauls in China, while Pakistan Aeronautical Complex (PAC) Kamra has gained experience in integrating and servicing the propulsion system locally.

This boosts Pakistan’s industrial autonomy and improves the credibility of its export ambitions, particularly toward Azerbaijan, Myanmar, and Nigeria, which have shown renewed interest in the JF-17 platform.

INDIA’S STRATEGIC RESPONSE

India, meanwhile, is recalibrating its air-defence posture and procurement priorities in response to Pakistan’s evolving capabilities.

During Operation Sindoor in May 2025, Indian radar operators and electronic intelligence units closely studied PAF JF-17 operations, identifying engine performance signatures that could aid future counter-air planning.

Indian Air Force officials privately acknowledge that familiarity with the RD-93 family of engines gives India a critical tactical advantage.

The Su-30MKI and MiG-29UPG share similar propulsion systems, allowing Indian engineers to exploit acoustic and thermal signatures of the JF-17 for radar tracking and infrared countermeasure optimization.

Moreover, New Delhi continues to diversify its own fighter mix—adding 36 Rafale fighters, developing the Tejas Mk-2, and advancing the Advanced Medium Combat Aircraft (AMCA) program, all of which aim to offset Pakistan’s gains.

In addition, India’s ongoing procurement of S-400 Triumf systems provides an additional deterrent layer, giving it the capability to detect and engage low-RCS targets like the JF-17 before they cross Indian airspace.

ECONOMIC MOTIVATIONS BEHIND MOSCOW’S DECISION

From Moscow’s perspective, the RD-93MA export is an economic necessity.

Following the Ukraine war, Russia’s defence industry has suffered a sharp contraction in Western contracts, prompting an aggressive pivot toward Asia, the Middle East, and Africa.

The United Engine Corporation (UEC), which oversees Klimov, has sought to maintain production continuity of the RD family by courting emerging customers like Pakistan, Algeria, and Myanmar.

Industry analysts estimate that the Pakistan engine contract could be worth USD 250 million (RM1.18 billion) over five years, providing critical revenue to sustain Russia’s aerospace supply chain amid sanctions.

Additionally, by supporting Pakistan—a close ally of China—Russia reinforces its strategic alignment with Beijing, ensuring continued cooperation on major platforms such as the Su-35, S-500 air defence system, and civilian aerospace programs.

A TEST OF INDIA-RUSSIA TRUST

The RD-93 episode exposes a deeper truth: India’s strategic dependence on Russian equipment is no longer matched by exclusive political alignment.

Over 65 percent of India’s military hardware remains of Russian origin, from the INS Chakra nuclear submarine to T-90 Bhishma tanks and Su-30MKI fighters.

Yet, Moscow’s growing closeness with Beijing—and by extension Islamabad—has forced India to diversify toward Western partners, including France, the U.S., and Israel.

This realignment of defence sourcing is already visible through joint projects like the GE-F414 engine for Tejas Mk-II, MQ-9B SeaGuardian drone procurement, and Dassault Aviation’s Rafale M for the Indian Navy.

However, analysts caution that India’s gradual shift away from Russian systems will take at least a decade, given the depth of existing dependencies in logistics, ammunition, and spares.

AN IRONIC STRATEGIC ADVANTAGE FOR INDIA

Ultimately, while the optics of Russia supplying engines to Pakistan appear politically controversial, experts like Pyotr Topychkanov argue that the strategic balance may paradoxically favor India.

By relying on the same Russian engines, Pakistan exposes the technological limits of its JF-17 program and makes its fleet more predictable to Indian intelligence and engineers familiar with the RD-33 lineage.

In essence, the RD-93MA deal underscores the interdependence of adversarial airpower in South Asia—where Moscow’s pursuit of financial gain and survival amid sanctions inadvertently reinforces India’s tactical understanding of its opponent’s systems.

For New Delhi, the incident serves as both a warning and an opportunity: a reminder that Cold War loyalties no longer guarantee exclusivity, but also a chance to exploit Russia’s technology commonality to its strategic advantage.

As the region’s skies grow more contested, the battle for supremacy will not only be fought with missiles and jets—but also with data, familiarity, and foresight.

Defence analysts further assert that India could leverage its deep operational experience with the RD-33 engine family to enhance simulation-based wargaming and predictive maintenance algorithms, giving the Indian Air Force (IAF) an upper hand in anticipating the JF-17’s performance envelope under combat stress.

The shared engine lineage also allows Indian radar and electronic warfare (EW) specialists to fine-tune signal recognition and target discrimination systems, particularly across the Western theatre where JF-17s are most likely to be deployed.

Additionally, the development highlights how Moscow, despite facing isolation from Western arms markets, continues to act as a central technological conduit connecting rival states—creating a unique “strategic triangle” that binds Russia, India, and Pakistan within overlapping dependency chains.

This dynamic reinforces the argument that India’s next phase of defence strategy must prioritize propulsion self-reliance through indigenous engine programs such as the GTX-35VS Kaveri and collaborative ventures with France’s Safran to escape this cyclical reliance on Russian technology.

Ultimately, the RD-93 episode encapsulates a paradox at the heart of South Asian defence geopolitics—where Russia’s economic pragmatism and India’s technological adaptability converge to sustain a fragile equilibrium that may define the regional airpower landscape for the next two decades. — DEFENCE SECURITY ASIA
