Modern engineering reaches its peak in jet engine manufacturing. The fusion of metallurgy, aerodynamics, thermodynamics, and digital controls in one compact, high-performance unit makes this a domain dominated by a few global players. For India, a country striving for strategic autonomy and self-reliance under the Aatmanirbhar Bharat initiative, developing indigenous jet engine capabilities is not just a technological goal but a geopolitical necessity.
The road to jet engine self-sufficiency is riddled with obstacles.
The Technology Transfer Conundrum
- What percentage of the Technology of the Future (ToT) is the future foreign partner willing to transfer to India?
- India’s efforts to co-develop jet engines often stumble at the barrier of limited technology transfer. Typically, Original Equipment Manufacturers (OEMs) retain 70-80% of Intellectual Property (IP) rights. The remainder lies with a network of specialized vendors whose cooperation is crucial for complete technology absorption.
- Will these vendors be willing to transfer their expertise, known as ‘training of technology’ (ToT), to India?
This quest is not just a technological pursuit, but a strategic imperative for India’s future.
Without access to the “know-how” – the nuanced, often undocumented expertise in materials, processes, and performance testing – India cannot master the art of high-thrust, high-efficiency military engines.
So far, most ToT agreements have focused on manufacturing rights rather than full capability development.
Funding and the Private Sector’s Role
Suppose private players are key to designing, developing, and manufacturing the AMCA engine. Will the Indian Ministry of Defence be ready to cover the non-recurring costs for the equipment and fixtures required for engine part manufacturing?
Private industry, with its agility and efficiency, has the potential to enhance India’s capabilities significantly. However, this potential can only be fully realized with government backing to cover initial capital expenditures, especially for specialized tooling, testing rigs, and certification protocols.
Bharat Forge’s refusal in 2015 to invest in tooling for the Kamov 226 T engine highlights the need for public-private collaboration. The state must underwrite risks in strategic projects where returns are neither quick nor guaranteed.
Lessons from HAL’s Experience
Hindustan Aeronautics Limited’s (HAL) experience with the Shakti Engine exemplifies the challenges of indigenization. Despite obtaining a production license in 2003, full indigenization was not achieved. This signals structural issues, including a lack of full access to design documentation, limited supplier ecosystems, and inadequate test infrastructure.
A cautionary tale, the Shakti experience highlights the importance of developing deep capabilities rather than relying on shallow assembly lines.
Profit Lies in Spares, Not Engines
Globally, original equipment manufacturers (OEMs) do not typically profit from manufacturing engines. Their revenue comes from spares and maintenance. Primarily, hot-section parts, such as turbine blades and combustion liners, are frequently replaced, offering recurring revenue streams. Whoever makes spares wins.
India’s strategic and economic completeness hinges on its ability to master the metallurgy and coating technologies that allow it to produce high-wear components domestically. Without this, any engine program will remain strategically and economically incomplete.
The Post-Sindoor Strategic Shift
Operation Sindoor marked a pivotal shift in India’s defense posture. Following a proactive military response to cross-border terrorism, India’s leadership adopted the “Sindoor Doctrine” – any further aggression will face swift retaliation. This doctrine, named after the red mark traditionally worn by Indian women, symbolizes India’s commitment to defend its sovereignty and respond decisively to any threat to its security.
In this new paradigm, the speed of force deployment is critical. The Indian Air Force (IAF), short of its ideal squadron strength (42 vs. current 31), needs rapid fighter induction. This urgency is driving the reconsideration of traditional procurement models and a push for indigenous engine production.
Existing Dependencies and Their Fallout
GE Aerospace currently supplies F404-IN20 engines for Tejas Mk-1 jets. Delivery delays have slowed the Indian Air Force’s upgrade cycle. This dependency underscores the risks of relying on a single foreign source, particularly one that is subject to export controls and geopolitical shifts.
The Safran Option
India is exploring collaboration with France’s Safran, a leader in aviation propulsion. Safran already partners with HAL on helicopter engines. If successful, this partnership could extend to powering the Tejas Mk-2 and possibly the AMCA, potentially transforming India’s defense capabilities and reducing its strategic vulnerability.
If the Safran option proves successful, it will be used to power the Tejas Mk-2.
This move aligns with India’s broader goal of diversifying its partners and reducing strategic vulnerability. However, success depends on Safran’s willingness to share critical IP and India’s ability to absorb it.

Legacy Programs and Their Limitations
India’s indigenous efforts began with the Kaveri engine, developed by the Gas Turbine Research Establishment (GTRE). Despite decades of effort, the Kaveri failed to deliver the required thrust and efficiency for frontline fighters. It has been repurposed for drones and auxiliary power applications.
The Kaveri experience underlines the need for cutting-edge research, international exposure, and continuous iterative development – attributes that India is still cultivating.
AMCA Execution Model: A Game-Changer?
To overcome legacy issues, the Ministry of Defence has unveiled a new Execution Model for the AMCA program. ADA will lead, but execution will be open to both public and private entities on equal footing.
This is a critical evolution. By allowing consortia and independent bids, the model encourages innovation, competition, and investment. Most importantly, it aims to build a scalable aerospace industrial base.
China Factor
China’s rapid strides amplify India’s urgency. The J20 and J35 stealth fighters are entering mass production. Some have already been deployed along the Line of Actual Control (LAC), posing a significant challenge to India’s defense preparedness and underscoring the need for rapid indigenous development.
India cannot afford to lag. Indigenous engine development is essential not just for cost or pride, but for parity and deterrence.
Strategic Recommendations
To navigate the labyrinth of jet engine manufacturing, India must pursue a multipronged strategy: –
- Negotiate Deeper ToT Agreements. Insist on co-development and design participation rather than production licenses.
- Create a Jet Engine Consortium. Involve HAL, DRDO, GTRE, Tata, L&T, Bharat Forge, and academia in a permanent, focused consortium.
- Fund Non-Recurring Costs. MoD should underwrite infrastructure and tooling costs to incentivize private participation.
- Invest in materials R&D, focusing on single-crystal blade technology, thermal barrier coatings, and superalloys.
- Develop Testing Infrastructure. Build testbeds for high-altitude, high-thrust simulations.
- Leverage Dual-Use Technologies. Use commercial aviation and space tech as springboards for military applications.
Conclusion
Jet engine development is India’s Mount Everest. The challenges are steep, the timeline long, and the resources immense. But the prize—genuine strategic autonomy—is worth the climb.
The AMCA engine, a highly complex engineering Project, offers a unique opportunity. While it may take 5 to 6 years to mature, the potential technological and strategic benefits make it a worthwhile endeavor.
India must learn from its past, fund its future, and forge partnerships that prioritize mutual growth over asymmetric dependencies.
Only then can the country power its skies with engines made at home for missions of its choosing.
