Empowering India’s skies: GE Aerospace and HAL’s breakthrough deal for LCA Mk2 engines

The bilateral agreement between GE Aerospace and Hindustan Aeronautics Limited (HAL) encompasses a comprehensive transfer of complex engine technologies to India, marking a significant stride in the nation’s quest for advanced aerospace capabilities.

The collaborative venture between GE Aerospace and Hindustan Aeronautics Limited (HAL) to produce fighter jet engines has secured approval from the United States Congress. Originating from discussions initiated during Prime Minister Narendra Modi’s visit to the U.S. in June, this agreement is set to enhance the defence partnership between India and the U.S.

The core of this collaboration involves the domestic manufacturing of F-414 jet engines specifically designed for the in-progress development of the light combat aircraft (LCA) Mk2. This approval marks a significant step forward in fostering technological and strategic ties between the two nations in the defence sector.

Valued at approximately $1 billion, the deal encompasses an 80 per cent transfer of technology (ToT). This strategic arrangement anticipates a significant surge in indigenous content for the new fighter jet, reaching an estimated 75 per cent. This noteworthy increase stands in sharp contrast to the reported 55-60 per cent indigenous content for LCA Mk-1A and the 50 per cent seen in the existing variants.

The conclusive arrangement with GE Aerospace is expected to encompass the licensed production of 99 F-414 engines, and it is anticipated to be finalized within the current fiscal year. The initial batch of these engines is projected to undergo manufacturing in India approximately three years from the present timeline.

The Transfer of Technology (ToT)  involved in the agreement spans 11 critical areas, showcasing a notable shift from a decade ago when initial discussions between GE and India’s Aeronautical Development Agency (ADA) commenced. In contrast to the earlier arrangement, which only included a 58 per cent transfer of technology, the current agreement marks a significant expansion, providing India access to crucial engine technologies that were previously withheld.

The F-414 engine represents an advancement from the F-404 engine, currently utilized to power the LCA Mk1 and Mk1A. In February 2021, the Indian Air Force finalized a contract for 83 Mk-1A jets, bringing the cumulative orders for various LCA variants to 123. The earlier versions of LCA Mk-1 are progressing through different stages of operational clearance.

The upcoming LCA Mk-2 is expected to hold a crucial position in the future combat capability of the Indian Air Force, and there are intentions to manufacture a total of 130 of these fighter jets. This underscores the continued development and expansion of India’s indigenous fighter aircraft program.


The collaboration between GE Aerospace and Hindustan Aeronautics Limited (HAL) is being hailed as a “big game changer” by HAL Chief CB Ananthakrishnan, as it lays the foundation for future indigenous engines powering military jets. This partnership is not only significant for technological advancement but also has economic benefits. The deal involves the co-production of 99 jet engines, and the cost-effectiveness is expected to be enhanced due to the transfer of technology.

The F414 engines, chosen for their renowned reliability and performance, are set to play a pivotal role in bolstering the capabilities of the Indian Air Force. The technology transfer aspect of the agreement is particularly noteworthy, as it empowers India with the knowledge and expertise to develop and produce its military jet engines in the future.

As part of this collaboration, GE Aerospace is poised to expand its presence in India, further contributing to the nation’s aerospace capabilities. The boost in facilities includes a range of services such as engines, avionics, engineering, manufacturing, and local sourcing. This not only fosters technology transfer but also strengthens the overall aerospace ecosystem in India.

Furthermore, GE Aerospace has expressed its commitment to continuing collaboration with the Indian government on the Advanced Medium Combat Aircraft (AMCA) Mk2 engine program. This signifies a sustained partnership in the development of advanced technologies for future military aviation, emphasizing the enduring nature of the relationship between GE Aerospace and India in the field of aerospace and defence.

The significance of the deal lies in the fact that the United States considers jet engine technology as a highly valuable asset, often treated as a “crown jewel,” and traditionally, such technology has not been shared even with close allies. This agreement represents a departure from that norm, as it involves the transfer of critical jet engine technology to India. This is particularly crucial for India, which has faced challenges in advancing its jet engine technology.

By bridging this technological gap, the agreement has the potential to strengthen India’s aerial capabilities, especially in the context of the delicate situation with China at the Line of Actual Control. Additionally, it aligns with India’s broader ambition of establishing a robust domestic defence industrial base.

US administration officials have acknowledged that the GE deal could serve as a model for future collaborations. This is significant not only in addressing India’s concerns regarding technology transfer and co-production but also in realizing the American vision of closely integrating the defence ecosystems and platforms of both countries. The collaboration reflects a strategic alignment of interests, fostering technological cooperation and potentially opening doors for further collaborations in the defence sector between the United States and India.

Major points

The bilateral agreement between GE Aerospace and Hindustan Aeronautics Limited (HAL) encompasses a comprehensive transfer of complex engine technologies to India, marking a significant stride in the nation’s quest for advanced aerospace capabilities. The deal includes expertise in machining and coating for single crystal turbine blades, fabrication techniques for powder metallurgy discs, and the application of inertia friction welding in the construction of components for the fan and afterburner sections. Laser drilling technology for precision in the combustor, special coatings addressing corrosion and erosion concerns, and the machining and coating of ceramic matrix composites for nozzle guide vanes are also part of the technology transfer. Further, the agreement involves the application of polymer matrix composites in bypass duct construction, the shaping and machining of thin-walled titanium casings, and specialized bottle boring techniques for shafts. This extensive knowledge exchange not only bolsters India’s technological prowess in jet engine manufacturing but also lays a foundation for sustained collaboration in advancing the nation’s aerospace capabilities.

The upcoming LCA Mk2 is poised to deliver substantial advancements in various aspects, according to officials involved in the project. This 17.5-tonne fighter aircraft is designed to offer improved range, enhanced survivability, heightened situational awareness for pilots, and advanced network-centric capabilities. One of its key features is the ability to seamlessly transition between different roles, showcasing its versatility in mission adaptability.

In terms of performance, the LCA Mk2 is expected to reach a maximum speed of 1.8 Mach, surpassing the 1.6 Mach top speed of its predecessor, the LCA Mk-1A, which weighs 13.5 tonnes. Additionally, the new aircraft boasts an increased payload capacity of 6.5 tonnes, a significant upgrade from the 3.5 tonnes of the Mk-1A  This expanded payload capacity enables the LCA Mk2 to carry a diverse arsenal, including beyond visual range air-to-air missiles, air-to-ground missiles, heavy precision-guided weapons, and conventional bombs. These advancements collectively position the LCA Mk2 as a highly capable and versatile fighter aircraft, contributing to the Indian Air Force’s evolving operational requirements
