India to Pursue Homegrown Engine for Tejas Mk-2 as F-414 Deal Faces Uncertainty

India's Quest for Self-Reliance in Fighter Jet Engines

India's aspirations in the realm of combat aviation are poised to take a significant leap forward with the development of a high-thrust indigenous engine programme. This ambitious project, which aims to create an engine capable of powering the Advanced Medium Combat Aircraft (AMCA), could also have far-reaching implications for the Tejas Mk-2, India's indigenous fighter jet programme.

According to a senior official from the Defence Research and Development Organisation (DRDO), the indigenous 120 kilonewton-class engine being proposed for the AMCA could also be used for the Tejas Mk-2, including in future mid-life upgrade versions, should the long-delayed agreement for the local production of the GE F-414 engine not come through. This contingency plan is being developed as a safeguard against the potential failure of the F-414 deal, which has been plagued by delays and disagreements over technology transfer.

The F-414 engine, currently used in the Tejas Mk-2 prototypes, is being produced in large numbers for various aircraft, including the Boeing F/A-18 and the Saab Gripen-E. However, talks with General Electric and Hindustan Aeronautics Limited (HAL) to transfer 80% of the technology have been slow, and the Ministry of Defence is keen to explore alternative options.

A New Era for Aero-Engine Manufacturing in India

The Gas Turbine Research Establishment (GTRE) has taken a significant step towards enhancing India's native engine industry by launching an Expression of Interest (EoI) to find an Indian industrial partner for the manufacturing and assembly of an Indigenous Advanced High Thrust Class Aero Engine. The EoI seeks a Development-cum-Production Partner who can manage the intricacies of aero-engine integration and precise manufacturing.

The initiative has sparked a quiet industrial development, with GTRE inviting Indian companies to participate in the programme. This move marks a significant shift towards aero-engine manufacturing, which will no longer be restricted to government laboratories. As the programme expands, precision metallurgy, advanced coatings, and complex rotating machinery will have to move into the private sector, potentially transforming India's aerospace supply chain for decades to come.

A National Backup Option

The domestically developed 120 kN engine is being presented as a future replacement for the F-414 engine, rather than a distant aspiration. This engine is not only intended for use in a fifth-generation fighter but also as a national backup option to guard against negotiations coming to a standstill and changes in the geopolitical situation.

The decisions taken in the coming months will have far-reaching implications for the AMCA and Tejas Mk-2 programmes. The control of the engine is crucial, as it will determine the overall performance of the aircraft. If control of the engine is not achieved, then control of the aircraft as a whole will still be incomplete.
