India is on the cusp of a significant milestone in its defence capabilities, particularly concerning the development of indigenous aero engines. A crucial decision regarding the manufacture of these engines is anticipated in 2025, which could reshape India's aerospace landscape and enhance its self-reliance in defence technology.

The DRDO lab Gas Turbine Research Establishment (GTRE) initiated the Kaveri engine project in the 1990s to power the Light Combat Aircraft (LCA) TEJAS. However, the Kaveri engine did not meet the required thrust levels for the TEJAS, leading to its discontinuation for this application.

The Indian aerospace sector has faced numerous challenges in developing advanced jet engines. Key issues include:

Technological Complexity: Designing and manufacturing modern jet engines require sophisticated technology and expertise, which India has been gradually building over time.

Material Science Limitations: Developing materials capable of withstanding the extreme conditions within jet engines has proven to be a significant hurdle.

Testing Infrastructure: The lack of advanced testing facilities in India has necessitated conducting high-altitude tests abroad, particularly in Russia, which has delayed progress

Strategic Partnerships And Technology Transfer

International Collaborations: To address these challenges, India is actively pursuing collaborations with international partners. Notably, General Electric (GE) has expressed readiness to supply F414 engines for the TEJAS MK-2 and is open to joint production in India. Other companies, such as Rolls-Royce and Safran, are also interested in co-developing bespoke engines, offering full transfer of intellectual property to support India's goal of self-reliance in defence technology.

Research And Development Initiatives: A focus on developing indigenous aero engines will likely spur investment in research and development within India. This could enhance technological expertise in materials science, engine design, and testing infrastructure—areas that have historically posed challenges for India's aerospace sector.

Long-Term Defence Self-Sufficiency

Reduction of Import Dependency: By establishing a robust domestic engine manufacturing capability, India can significantly decrease its dependency on imported engines. This shift is essential for achieving long-term sustainability in defence manufacturing and ensuring that India can independently support its military aviation needs.

Broader Defence Ecosystem Impact: The successful development of indigenous aero engines will not only benefit fighter aircraft but also enhance capabilities across various platforms, including unmanned aerial vehicles (UAVs) and future stealth aircraft. This diversification will strengthen India's overall defence posture and technological base.

The anticipated decision in 2025 aligns with India's broader initiative known as Atmanirbhar Bharat or self-reliant India. This initiative aims to bolster domestic capabilities in various sectors, including defence. The focus on developing indigenous aero engines is critical for enhancing India's air combat capabilities and reducing dependency on foreign suppliers.

As part of this strategy, the Hindustan Aeronautics Limited (HAL) is set to receive its first two F-404 engines from GE Aviation by March 2025, marking a pivotal step towards operationalizing the indigenous Light Combat Aircraft (LCA) TEJAS MK-1A. However, delays in engine deliveries have raised concerns regarding the operational readiness of the Indian Air Force (IAF), emphasizing the urgency for India to establish its own engine manufacturing capabilities.

Looking ahead, the successful development of indigenous aero engines could lead to several strategic advantages for India:

Enhanced Defence Capabilities: A robust domestic engine manufacturing capability would significantly enhance India's defence capabilities and operational readiness. The ability to produce advanced aero engines domestically will significantly reduce India's reliance on foreign suppliers, thereby enhancing operational readiness and strategic autonomy. This is crucial given the current geopolitical tensions with neighbouring countries like China and Pakistan.

Faster Deployment of Aircraft: Delays in engine deliveries, such as those affecting the TEJAS MK-1A, have hindered the Indian Air Force's (IAF) modernization efforts. The timely decision in 2025 could streamline production processes and facilitate quicker deployment of advanced fighter jets, improving the IAF's overall combat readiness.

Export Opportunities: With successful development and testing, India could position itself as a supplier of advanced aero-engine technology to other nations.

Technological Independence: Achieving self-sufficiency in aero-engine technology would provide India with greater strategic autonomy and reduce vulnerabilities associated with foreign dependencies.

2025 is poised to be a transformative year for India's aerospace sector. The decisions made regarding aero engine manufacturing will not only impact India's defence capabilities but also contribute to its long-term strategic goals in self-reliance and technological advancement.

Renowned defence analyst Nitin A. Gokhale, Editor-in-Chief of bharatshakti defence web portal, feels that 2025 will be the year in which the significant decision of the manufacture of the aero-engine will be taken.
