New Delhi: India’s indigenous military helicopter programme is moving closer to its development phase, with the Cabinet Committee on Security (CCS) expected to consider a ₹13,500 crore proposal for the design and development of Hindustan Aeronautics Limited’s (HAL) Indian Multi-Role Helicopter (IMRH).
According to sources, the allocation has already been cleared by the costing committee and is now expected to move before the CCS for approval. The first phase of the programme will primarily focus on the design and development of the 13-tonne medium-lift helicopter.

The IMRH is being developed by HAL as an indigenous medium-lift platform for the Indian Army and Indian Air Force, with the eventual objective of replacing the IAF's ageing fleet of Russian-origin Mi-17 helicopters.
The IMRH programme is closely linked to the development of its new-generation powerplant, the Aravalli turboshaft engine.
HAL and Safran Helicopter Engines recently signed the final contract with their joint venture, SAFHAL Helicopter Engines Pvt Ltd, for the development and manufacture of the Aravalli engine.
The engine has been selected to power both the IMRH and its naval derivative, the Deck-Based Multi-Role Helicopter (DBMRH) being developed for the Indian Navy.
The Aravalli is being designed for medium-lift helicopters in the 3,500–4,000 shaft-horsepower class. Its development programme covers the complete product cycle, including design, development, manufacturing, supply and lifecycle support.
Both the IMRH and DBMRH are twin-engine platforms. This makes successful development, integration and testing of the Aravalli a critical dependency for the future progress of both helicopter programmes.
One engine, three services:
The significance of the programme extends beyond replacing an ageing helicopter fleet.
The IMRH is being developed for the Army and Air Force, while its naval variant is intended for the Indian Navy. A common helicopter family across multiple services could therefore provide a broader indigenous platform base for India's military aviation requirements.
It also brings together two important strands of India's defence-industrial strategy: HAL's indigenous platform development and international collaboration for advanced propulsion technology.
For India, developing a modern medium-lift helicopter and its associated engine represents a major aerospace challenge. Helicopter engines are among the most technologically demanding components of military aviation, requiring high levels of expertise in materials, combustion, power transmission, reliability and testing.
The Aravalli programme therefore have a major significance instead of just being a single helicopter. Successful development would contribute to India's ability to build and sustain a more advanced indigenous aerospace ecosystem.
The IMRH programme could eventually reduce dependence on imported medium-lift helicopters while creating a domestic platform that can serve requirements across India's Army, Air Force and Navy.
For HAL, the programme represents another major step in expanding India's indigenous rotary-wing capabilities. For India's wider defence industry, it could generate opportunities across manufacturing, components, systems integration and lifecycle support.
The immediate milestone, however, remains the proposed ₹13,500 crore design-development approval.
If cleared by the CCS, the programme would move another step closer to turning India's requirement for a next-generation medium-lift helicopter into an indigenous operational capability.
The bigger story is not just a new helicopter — it is India's attempt to build the platform, develop its engine and create the industrial ecosystem needed to sustain it at home.
