RD-93MA Engines: Russia Sidesteps India’s Request
Why the story matters
Several OSINT Reports indicate Russia will not block RD-93MA engines for Pakistan Air Force, despite an Indian request to halt supplies. If correct, this preserves Pakistan’s JF-17 Block III timeline and narrows India’s options to constrain PAF sustainment. The claim stems from Indian defence media; Moscow and New Delhi have not issued formal confirmations. Indian Defence Research Wing
What is the RD-93MA?
The RD-93MA is Klimov’s latest upgrade to the RD-93 family, offering a thrust class around 9,300 kgf and improved hot-and-high performance—key for a single-engine light fighter. UEC/Klimov disclosed test progress in 2020, noting enhanced thermodynamic parameters, updated fan/hot-section design, and a modernised control system tailored for single-engine safety margins. Therefore, RD-93MA engines for Pakistan Air Force promise better take-off performance and payload flexibility for Block III. Aviation Week+2Aviation Week+2
Is Block III actually using RD-93MA?
Open sources and show reports associate the JF-17 Block III with the RD-93MA, alongside avionics upgrades such as an AESA radar, wide-area display, and new HMD/S. Moreover, recent European show coverage described a Block III (JF-17C) powered by RD-93MA and carrying PL-10 and PL-15E missiles. That pairing underscores why RD-93MA engines for Pakistan Air Force are strategically important: they preserve the aircraft’s energy manoeuvrability while integrating long-range BVR weapons.

India’s reported ask—and limits of leverage
Indian outlets said New Delhi urged Moscow to stop RD-93 spares and engines amid tensions with Islamabad. However, the reported Russian response was a refusal. While the sourcing remains media-level, the episode spotlights the limits of Indian leverage over a matured Russian export line backed by Chinese programme equities. Consequently, RD-93MA engines for Pakistan Air Force are likely to keep flowing unless higher-level geopolitics intervenes. Indian Defence Research Wing
Technical implications for PAF
With RD-93MA, Block III gains a modest but meaningful thrust bump over baseline RD-93, improving time-to-climb and weapons bring-back in hot weather. Therefore, RD-93MA engines for Pakistan Air Force help sustain BVR envelopes with PL-15E while maintaining dash speed and sortie generation. Although the thrust increase looks small on paper, it compounds with weight reduction and avionics enhancements to improve overall mission effectiveness. Aviation Week+1
Russia’s incentives to say “no”
Russia’s defence industry needs steady hard-currency lines that are contractually anchored and tooling-ready. Moreover, blocking RD-93MA would stress ties with Beijing, given the JF-17’s China–Pakistan pedigree. Thus, maintaining RD-93MA engines for Pakistan Air Force likely aligns with Moscow’s revenue priorities and wider Asian balancing, even as India remains a major Russian customer in other programmes.

India’s likely counters
- Accelerate Tejas induction and MRO depth. India can offset PAF’s momentum by scaling Tejas Mk1A and maturing F404/F414 sustainment. This pathway reduces dependence on external vetoes while improving readiness.
- Target non-engine bottlenecks. Avionics, EW components, and seeker supply chains are harder chokepoints for a light fighter. However, these levers require multilateral alignment and long lead times.
- Either way, RD-93MA engines for Pakistan Air Force keep the JF-17 modernisation cycle intact, so New Delhi’s durable response is capacity, not denial.
Evidence base: what we know for sure
- UEC/Klimov publicly confirmed RD-93MA ground/bench testing in 2020, detailing performance and safety upgrades for a single-engine use case. Aviation Week+1
- Trade/industry outlets reported the engine’s progress and Block III pairing; 2025 show coverage in Europe described a Block III with RD-93MA and next-gen Chinese AAMs. Defense Mirror+1
- As of 30 September 2025, Indian defence media reported on the request to halt supplies, but official releases did not support it. Therefore, treat it as a strong media and OSINT claim, not a formal statement, but remember where there is smoke there is fire. Indian Defence Research Wing
