Hindustan Aeronautics Limited (HAL) is approaching a major milestone in India’s indigenous rotary-wing aviation program, with the maiden flight of its Utility Helicopter-Marine (UH-M) expected around November.
The twin-engine helicopter has been purpose-built for shipborne operations and is intended to meet the Indian Navy’s requirement for a modern naval utility platform capable of operating from frontline warships.
Speaking to Deccan Herald in Bengaluru, HAL Chairman and Managing Director Ravi K said the first UH-M prototype has already been built and is undergoing preparations for its initial flight-testing phase. The company expects the helicopter to conduct its maiden sortie around November, after which it will enter a broader development and certification program ahead of potential induction.
The UH-M is being developed to replace the Indian Navy’s ageing Chetak helicopter fleet. The Chetak has supported naval utility and logistics missions for decades, but its advancing age has created the need for a modern platform designed to meet contemporary maritime operational requirements.
HAL’s Naval Utility Helicopter
Development of the UH-M gained momentum after the Ministry of Defence issued a Request for Information (RFI) for 76 Naval Utility Helicopters. The requirement comprises 51 helicopters for the Indian Navy and 25 for the Indian Coast Guard.
HAL has designed the UH-M specifically around this requirement, aiming to provide an indigenous solution for a critical naval aviation capability.
Unlike conventional utility helicopters modified for maritime operations, the UH-M has been designed with shipborne missions as a core requirement. Naval helicopters must operate within confined deck and hangar spaces while facing strong winds, rough seas, salt-laden environments, and other demanding maritime conditions.
The helicopter incorporates several features intended to address these challenges. Among them is a blade-folding system that allows the aircraft to be stored within the limited hangar space available aboard naval vessels. Foldable rotor blades are a key feature for many shipborne helicopters and have been incorporated into the UH-M design from the beginning.
According to Ravi K, the helicopter also features enhanced engine performance and upgraded flight-control systems. These improvements are intended to provide greater power margins during take-off and landing from ships, particularly when operating from moving decks and under adverse environmental conditions.
The UH-M is also designed with a flexible cabin configuration. Its seating arrangement can be adjusted according to mission requirements, allowing the helicopter to transport personnel, conduct utility missions, or support medical evacuation.
This flexibility could enable the platform to perform a range of missions, including casualty evacuation, search and rescue, logistics support, personnel movement, and humanitarian assistance.
The program also reflects HAL’s efforts to address some of the challenges associated with earlier naval helicopter initiatives. Although the Indian Navy operates naval variants of the Advanced Light Helicopter Dhruv, their deployment across the fleet has faced certain limitations. The UH-M has instead been developed with dedicated naval modifications and an architecture tailored specifically to maritime operations.
Supporting Indian Naval Operations
The UH-M is expected to support Indian Navy operations across the Indian Ocean Region. Naval utility helicopters perform a wide range of roles, including personnel transfer, surveillance support, logistics, search and rescue, disaster relief, and communications.
As India’s maritime operational footprint expands, demand for versatile shipborne helicopters is also increasing. HAL is positioning the UH-M as an indigenous alternative to established foreign naval helicopter designs, with the platform designed around India’s operational requirements and maritime environment.
The program also aligns with India’s broader objective of increasing domestic defense manufacturing and reducing dependence on imported military platforms.
HAL’s Light Utility Helicopter Program
Alongside the UH-M, HAL is progressing with another major rotorcraft project, the Light Utility Helicopter (LUH). The single-engine helicopter is intended to replace ageing Cheetah and Chetak fleets operated by the Indian Army and Indian Air Force, including aircraft deployed in challenging high-altitude regions along India’s northern borders.
Ravi K said LUH certification activities are expected to conclude by December. Following certification, HAL plans to deliver an initial batch of 12 helicopters, with six aircraft each allocated to the Army and Air Force.
However, several technical areas still require further work before the LUH fully meets user requirements. According to Ravi K, the flight-control system requires additional refinement, while more flight hours are needed to optimize the aircraft’s software and overall performance.
One important area under evaluation is the helicopter’s autorotation capability. This safety feature allows a helicopter to perform a controlled descent and landing following an engine failure. Although HAL has conducted initial trials, additional testing is required to achieve the performance levels expected by the armed forces.
HAL remains confident that the outstanding technical issues can be addressed before the targeted December certification timeline. Successful certification would represent an important milestone for the LUH program and its intended role as an indigenous replacement for some of India’s oldest military helicopters.
Future LUH Procurement
The Indian Army and Air Force are together expected to require around 200 LUHs. However, the Ministry of Defence has yet to finalize a commercial contract with HAL for large-scale procurement.
Future acquisition decisions are expected to depend partly on the operational evaluation of the initial 12 helicopters. The services will assess factors including performance, reliability, maintainability, and compliance with operational requirements before larger procurement decisions are made.
The LUH is particularly significant because many Cheetah and Chetak helicopters are approaching the end of their operational lives. Despite their age, these platforms continue to perform important logistics, reconnaissance, and support missions in demanding environments, particularly across the Himalayan region.
HAL is also exploring potential civilian applications for the LUH. Ravi K indicated that the company intends to pursue civil certification, which could open opportunities in areas such as emergency medical services, disaster response, tourism, offshore operations, regional connectivity, and utility transportation.
If the UH-M and LUH achieve their respective development and certification milestones, the two programs could expand HAL’s indigenous helicopter portfolio while supporting the replacement of ageing military fleets.
The expected November maiden flight of the UH-M will therefore mark an important stage in India’s effort to develop a dedicated indigenous naval utility helicopter and strengthen domestic capabilities in military rotorcraft design and manufacturing.
