HAL accelerates the Indian Multi Role Helicopter (IMRH) project. It prepares a ₹13000 crore Cabinet Committee on Security (CCS) note. The proposal seeks approval to build five flying prototypes, including a naval variant, the Deck-Based Multirole Helicopter (DBMRH).

HAL Proposes Indigenous IMRH and Naval DBMRH Prototypes

HAL aims to develop both IMRH and its naval derivative simultaneously. It targets operational deployment across all three services. The company will fund 30% of the project from internal resources. The remaining 70% of the cost will come from the Government of India.

HAL takes initiative to break the project deadlock. This CCS note will unlock the execution phase. With government support, HAL expects a structured development timeline.

IMRH to Replace Mi-17 Fleet Across Services

The IMRH will replace aging Mi-17 helicopters. It will serve roles like troop transport, VIP movement, anti-submarine warfare, and air assault missions. HAL designs the helicopter to fulfill diverse needs across the Indian Army, Navy, and Air Force.

Additionally, it can carry cargo internally or as under-slung loads. The IMRH will fly at altitudes up to 20,000 feet. It will carry 24 troops or lift 3,500 kg of payload. HAL claims it can lift twice as much as the Dhruv helicopter. The Dhruv belongs to the five-tonne category. Moreover, HAL believes the Indian Army alone may need 400 helicopters in this class.

Scaled Model Tests Already Underway

HAL has already begun testing scaled-down models. Engineers started this phase in 2021. The company expects the first full-scale prototype to fly between 2025 and 2026. The helicopter will feature a five-blade main rotor spanning 21.2 meters. It will also use a four-blade tail rotor for stability. HAL will build the IMRH with 75% indigenous content. However, it will use a 2000 kW turboshaft engine developed through a joint venture. HAL and Safran will co-develop this engine under the name Aravali. The engine will provide reliable power across high altitudes and tough environments. Despite foreign collaboration, HAL will ensure strong local participation in production. This approach will balance capability with self-reliance.

HAL is setting up a new Helicopter Factory at Tumakuru. The facility will handle helicopters from 3 to 15 tonnes. Initially, the IMRH project was to follow the SPV model under DAP 2020. The plan required a private vendor to hold 51% stake and secure minimum confirmed orders. However, no private company came forward. As a result, HAL decided to proceed without forming an SPV.

The Government acknowledged that no Indian firm could independently build such a helicopter. This realization unlocked the project’s future. HAL then stepped in to lead development directly. On 6 February 2023, Prime Minister Narendra Modi inaugurated the Tumakuru Helicopter Factory. The plant will manufacture up to 1,000 helicopters in total. It will meet all domestic needs and eliminate import dependence.

HAL will produce the IMRH, LUH, ALH, and LCH at this site. Furthermore, the factory will offer full maintenance, repair, and overhaul support. This step strengthens India’s vision for self-reliant aerospace manufacturing.
