Why is News :
- India is pushing for indigenous defence manufacturing (e.g., AMCA stealth fighter), but continues to face a critical gap in engine technology, exposing a strategic vulnerability.
Key Issues
Historical Lessons: HF-24 Marut Failure
- India’s first indigenous fighter (1960s) failed not due to design but due to underpowered imported British engines.
- Highlighted how propulsion defines performance, not just airframe design.
Kaveri Engine Project: Chronic Delays
- Initiated in 1989 by DRDO-GTRE; spent ₹2,032 crore.
- Despite multiple prototypes and flight tests, it failed to meet thrust, reliability, and thermal benchmarks.
- Collaboration with Safran (France) collapsed; attempts at spin-offs unsuccessful.
Current Dependencies
- LCA Tejas Mk1A uses imported GE F404 engine; deliveries delayed by over a year, impacting IAF squadron readiness.
- HAL–GE F414 engine deal for LCA Mk2 & AMCA Mk1 faces bottlenecks over costs and technology transfer resistance (e.g., single-crystal blades, advanced cooling).
Wider Military Impact
- Army’s Arjun tank uses German engines; Zorawar light tank uses U.S. powerplant.
- Navy’s destroyers, frigates, corvettes rely on foreign propulsion (Russian, Ukrainian, French, German).
- No major engine platform in India is truly indigenous.
Why This Matters
- National Security Risk: Foreign engine embargoes or delays can cripple combat preparedness.
- Export Bottlenecks: Dependent platforms need third-party clearance for international sale
- Strategic Autonomy: Indigenous propulsion is central to Atmanirbhar Bharat and India’s global defence ambitions
- Industrial Capability: Jet engine tech is a benchmark of high-end R&D, metallurgy, material science, and precision engineering.
Way Forward
Political Will & Vision
- Defence funding must move from project-based to long-term strategic programs.
- Create a National Jet Engine Mission, like ISRO or BARC models.
Collaborative R&D Ecosystem
- Leverage private sector innovation, academia, and international partnerships.
- Encourage public-private-academic consortia for propulsion research.
Technology Transfer & JV Push
- Revisit deals with Safran, Rolls-Royce, GE; incentivise genuine ToT with IP sharing, not just screwdriver tech.
Diversified Investments
- Focus on multi-platform propulsion — air, sea, and land — to build cross-sectoral expertise.
Incentivise Indigenous Supply Chains
- Invest in advanced materials, cooling systems, turbine tech, and AI-based testing.

Singh Example:LCA Mk1A delayed due to 13-month delay in GE F404 engine supply — real-time example of strategic vulnerability. Data Point:India has spent ₹2,032 crore on the Kaveri engine but has no operational product in 35 years. |
