‘Cheetah’ and ‘Chetak5 are the names of:

‘Cheetah’ and ‘Chetak’ are the names of light utility helicopters used by the Indian Armed Forces. The HAL Chetak is a license-built version of the French A rospatiale Alouette III, introduced to the Indian Air Force in 1962 [1]. The HAL Cheetah is a license-built version of the A rospatiale SA 315B Lama, which was delivered to the Indian Air Force starting in 1976 [2]. These single-engine helicopters have served for decades in roles such as reconnaissance, casualty evacuation, and light transportation. While the Chetak features a wheeled landing gear, the Cheetah is sleeker and utilizes skis, making it suitable for high-altitude operations in the Himalayas [2]. Both fleets are currently being phased out and replaced by modern indigenous platforms like the HAL Light Utility Helicopter (LUH) and the Advanced Light Helicopter (ALH) Dhruv [1].
