HAL’s Light Utility Helicopter is powered by a single turbo shaft engine, which gives it adequate power margins to accomplish high-altitude missions in Ladakh and Siachen with ease
The Indian Air Force (IAF) will procure six Light Utility Helicopters (LUHs), designed and developed by Rotary Wing Research and Design Centre of Hindustan Aeronautics Limited, the newly appointed chief of the IAF, Air Chief Marshal VR Chaudhari, revealed in a presser today.
The helicopters will replace the ageing fleet of Cheetah and Chetak utility helicopters in service with the IAF. It is capable of carrying more than eight times the meaningful payload to the highest helipads in the world, as compared to the Cheetahs, reports say.
The LUH has undergone rigorous testing. In August last year, in the middle of the standoff with China, two prototypes of the helicopter landed in Ladakh for capability demonstration.
To reach Ladakh, the prototypes flew from Bangalore to Leh, a distance of over 3,000 km, in three days, without performance issues.
In 2019, an LUH prototype operated from Daulat Beg Oldie, the highest airfield in the world, lying close to the border with Tibet.
The helicopter is powered by a single turbo shaft engine Ardiden 1U from French aerospace supplier Safran with adequate power margins to accomplish high-altitude missions in Himalayas with ease.
“Since its first ground test in 2015, the Ardiden 1U maturation and certification campaign has accumulated around 1,000 hours of operation,” the engine maker adds.
The helicopter is capable of flying at 220 kmph, has a service ceiling of 6.5 km, and a range of 350 km with 500 kg payload.

LUH had received Initial Operational Clearance for the Indian Army from the Centre for Military Airworthiness and Certification at Aero India 2021.
“All certification activities like ground testing, Ground Test Vehicle endurance runs, system testing, flight testing including hot weather trials, cold weather trials, sea level trials and hot weather high altitude trials have been completed. Based on the flight trials carried out, all PJSQR requirements for basic helicopter certification have been complied with satisfactorily,” the Ministry of Defence said in February.
Over the next few years, the Army and the Air Force are likely to place orders for over 200 such helicopters to replace Cheetahs and Chetaks.
