HAL and Safran Sign Aravalli Engine Co-Development Contract

Hindustan Aeronautics Limited (HAL) and Safran Helicopter Engines have finalized a contract to co-develop the new-generation Aravalli engine, marking a definitive shift in Indian aerospace manufacturing from licensed production to indigenous propulsion design.

The agreement, signed on August 26, 2026, in Bengaluru, India, formalizes the design, development, manufacture, and lifecycle support of the engine through SAFHAL Helicopter Engines Pvt. Ltd. SAFHAL is a 50:50 joint venture between the two aerospace manufacturers. The Aravalli engine is slated to power India’s future 13-ton Indian Multi-Role Helicopter (IMRH) and its naval variant, the Deck-Based Multi-Role Helicopter (DBMRH).

Technical specifications and manufacturing

The Aravalli engine will operate in the 3,500 to 4,000 shaft horsepower (shp) class. Under the terms of the agreement, HAL will gain access to core engine technologies, including the high-pressure compressor, power turbine, and accessory gearbox. This technology transfer is designed to build domestic intellectual property and expertise in high-power engine design.

Manufacturing operations for the Aravalli program will be based at HAL’s facility in Tumakuru, Karnataka. Safran Helicopter Engines Chief Executive Officer Cédric Goubet noted the precedent set by the agreement in a press release issued by HAL.

“This is the first time Safran HE has taken up such a class of engine as co-development. The Aravalli engine programme represents a new chapter in the strategic relationship between France and India, combining the expertise of our teams to develop propulsion systems for future Indian rotorcraft.”

Development timeline and strategic shift

The final contract follows a multi-year negotiation and planning phase. HAL and Safran initially signed a Memorandum of Understanding for the project in July 2022, followed by detailed workshare discussions at Aero India in February 2023. The companies executed an airframer contract on August 30, 2024, to commence joint design work.

The design and development phase is targeted for completion between 2032 and 2033. Once operational, the IMRH platform is intended to replace the Indian Air Force’s aging fleet of Mil Mi-17 Helicopters. HAL Chairman and Managing Director Ravi K emphasized the domestic industrial impact of the program.

“The signing of this contract marks a significant step forward in India’s pursuit of self-reliance in aero-engine technologies. Through this collaborative programme with SAFHAL and Safran Helicopter Engines, we are creating a strong foundation for powering next-generation Indian helicopter platforms.”

AirPro News analysis

The Aravalli engine contract represents a critical maturation point for India’s defense aviation sector. Historically, Indian aerospace manufacturing has relied heavily on licensed production of foreign designs, which limits domestic engineering capability and intellectual property ownership. By securing a 50:50 co-development structure that includes core engine components like the high-pressure compressor and power turbine, we view this agreement as a foundational step toward true Propulsion independence for the Indian military. If the 2032 to 2033 development timeline holds, HAL will be positioned not just as an assembler, but as a primary original equipment Manufacturers (OEMs) for high-power rotorcraft engines.
