Hindustan Aeronautics Limited (HAL) has signed a Manufacturing License Agreement (MLA) with GE Aerospace for the local production of the F414-INS6 turbofan engines that will power India’s upcoming TEJAS MK-2 fighter jets. The agreement marks a major step forward in India’s defence indigenisation strategy and aerospace self-reliance.
The signing of the MLA follows the Memorandum of Understanding (MoU) concluded in June 2023. Under the new agreement, GE Aerospace will transfer up to 80 percent of the engine’s manufacturing and technical data to HAL. The deal includes critical technologies such as single-crystal turbine blades, special coatings for high-temperature engine sections, and advanced laser drilling processes.
The F414-INS6 engine is a high-performance turbofan with a maximum thrust of 98 kilonewtons and a thrust-to-weight ratio of 9:1 with afterburner. It also features Full Authority Digital Engine Control (FADEC) and safety systems tailored for single-engine fighter aircraft. The engine is a proven platform with over 10 million flight hours logged in global fighter fleets, including the F/A-18E/F Super Hornet and the JAS 39 Gripen.
Negotiations for the agreement involved detailed pricing, technology transfer scope, and compliance procedures. Key certifications, including the U.S. State Department’s DSP-83 approval, were completed in September 2024, clearing the path for formal signing of the MLA. While the total value of the deal is estimated at around $1 billion based on 2023 price levels, pricing details are still being finalised.
Under the terms of the agreement, a dedicated production facility near Bangalore will be established. Manufacturing is expected to begin within two years of contract finalisation, with engine deliveries for the TEJAS MK-2 program anticipated to start within three years. The initial production target is 99 engines, with the potential for additional orders to support future platforms like the Advanced Medium Combat Aircraft (AMCA).
The TEJAS MK-2, classified as a medium-weight fighter, will feature next-generation avionics and greater payload capacity than its predecessor. The integration of the F414-INS6 engine will significantly enhance its combat performance and range.
This strategic collaboration is expected to boost India’s aerospace manufacturing capabilities, reduce dependence on foreign suppliers, and advance the country’s long-term vision for defence self-reliance. HAL’s partnership with GE Aerospace also opens avenues for future indigenous engine development and deeper industrial cooperation.
The agreement stands as a landmark in Indo-US defence ties and is expected to serve as a foundation for future joint aerospace projects involving high-end technology sharing and co-production.
