India today stands at a decisive moment in its fighter jet journey. The Safran engine proposal for LCA Mk-2 is not just about specifications; it is about trust, self-reliance, and strategic freedom. With the Tejas Mk2 set to replace ageing Mirage-2000, Jaguar, and MiG-29 fighters, the engine powering it will determine not only performance but also India’s aerospace independence.
At the heart of the debate lie fighter jet engine delays in India, the uncertainty of GE F414 supplies, and Safran’s bold promise of technology transfer. The question is simple: which engine will shape India’s future?
Why the Engine Decision Defines Tejas Mk2
The LCA Mk-2 (Tejas Mk2) is not just another upgrade. It is the fighter that will replace India’s Mirage-2000, Jaguar, and MiG-29 fleets. To achieve that, it needs an engine powerful enough to support:
- Uttam AESA radar and advanced avionics
- Indigenous weapons like Astra, BrahMos-NG, and precision-guided munitions
- High payload capacity for multirole missions
- Supercruise and agility for modern dogfights
That is why the choice between GE F414 vs Safran M88-4 vs Safran M88 T-Rex has become central to the future of Tejas Mk2.

Safran M88-4 Engine for Tejas Mk2: A Plug-and-Play Option
Safran’s strongest pitch is the M88-4 engine for Tejas Mk2, an advanced variant of the engine that powers the Rafale. Delivering 95–105 kN thrust, it falls in the same range as the GE F414 already selected for Mk2.
Why does it matter? Because the M88-4 is designed as a plug-and-play solution:
- Minimal modifications to the Mk2’s airframe
- Strong Transfer of Technology (ToT) commitments
- Potential localisation of Rafale engine production in India
- Boost to the indigenous jet engine manufacturing ecosystem
For me, this makes the M88-4 not just a technical fit but also a strategic one. It can power the Tejas Mk2 while giving India the engine know-how it desperately needs.

Safran Proposed M88 T-Rex Engine for Tejas Mk-2
The other option on the table is the M88 T-Rex engine for Tejas Mk-2. Unveiled at the Paris Air Show 2025 for the Rafale F5, this engine delivers 88–90 kN thrust, about 20% more than the baseline M88-2.
It incorporates:
- Improved low-pressure compressor
- Advanced turbine materials and cooling circuits
- Optimised nozzle aerodynamics
The M88 T-Rex engine performance is innovative, compact, and modular. But when I compare it with India’s needs, it feels underpowered. At 88–90 kN, it does not match the 98 kN thrust of the GE F414. Worse, adopting it could mean airframe modifications to Tejas Mk2, delaying its first flight planned for early 2026.
I see the T-Rex more as a future bet than an immediate solution.
GE F414 vs Safran M88-4 vs Safran M88 T-Rex
| Engine | Thrust | Pros | Cons |
|---|---|---|---|
| GE F414 | 98 kN | Proven, no redesign needed | U.S. delays, export controls |
| Safran M88-4 | 95–105 kN | Plug-and-play, strong ToT, Rafale link | Needs testing, less proven |
| Safran M88 T-Rex | 88–90 kN | Advanced tech, compact design | Underpowered, may delay Mk2 |
From this quick view, the M88-4 engine for Tejas Mk2 emerges as the most balanced choice, offering thrust, adaptability, and technology transfer, while avoiding U.S. dependency.
Geopolitical Factors: U.S. Delays vs French Reliability
Here lies the crux of the issue. India’s experience with the U.S. has been mixed.
- With the GE F404, Washington promised smooth supply, yet delays continue to plague Tejas Mk1A production.
- Now, with the GE F414 deal for Tejas Mk2, the U.S. again assures timely deliveries. But how trustworthy is that promise when only three engines have been delivered so far, with repeated supply chain excuses?
This track record raises serious doubts. Can India really rely on the U.S. to deliver the F414 in time for Mk2’s rollout? For me, the answer is uncertain.
France, however, tells a different story. Safran and Dassault have delivered Rafales on time, and French firms are already building aerospace facilities in India, from fuselage production to critical aero-components. Safran’s offer of technology transfer and local manufacturing further strengthens its credibility.
For India, Safran is not just a vendor but a partner willing to invest in our ecosystem. That is the key difference.

India’s Indigenous Backup: Kaveri Derivative Engine
One aspect often overlooked in this debate is India’s own effort. The Kaveri derivative engine programme is quietly making progress. Just last week, DRDO successfully integrated an afterburner on the Kaveri derivative, marking a major milestone.
Once certified, India plans to improve thrust performance further. This shows that while foreign partnerships with Safran or GE are important, India is also laying the groundwork for indigenous jet engine manufacturing under Atmanirbhar Bharat.
Risks and Timelines
Even with strong proposals, challenges remain:
- The M88 T-Rex engine performance is insufficient for Mk2’s combat role.
- The M88-4 engine for Tejas Mk2 still needs extensive testing and certification.
- Safran’s alignment with Rafale F5 timelines (early 2030s) could clash with India’s Mk2 induction goals (2028–29).
These risks, however, appear more manageable than the uncertainty tied to U.S. supply chains.
Conclusion: My Perspective
The Safran engine proposal for LCA Mk-2 is not just about thrust or performance; it is India’s choice between dependency and independence for its aerospace future.
- The GE F414 is powerful but burdened by U.S. delays and export restrictions.
- The M88 T-Rex is innovative yet underpowered for Tejas Mk2’s requirements.
- The Safran M88-4 engine for Tejas Mk2, backed by technology transfer and France’s reliability, offers the most balanced solution.
- India’s Kaveri derivative with afterburner is progressing steadily, providing a strong indigenous backup.
In this context, the Safran engine deal for Tejas Mk2 India not only ensures performance today but also lays the foundation for aerospace self-reliance tomorrow.
