This is what we found on Wikipedia regarding the dhruv:

The HAL Dhruv (lit. 'Unshakeable') is a utility helicopter designed and developed by Hindustan Aeronautics Limited (HAL) in November 1984. The helicopter first flew in 1992; though its development was prolonged due to multiple factors including the Indian Army's requirement for design changes, budget restrictions, and sanctions placed on India following the 1998 Pokhran-II nuclear tests.

The HAL Dhruv entered operational service in 2002. It is designed to meet the requirement of both military and civil operators, with military variants of the helicopter being developed for the Indian Armed Forces, while a variant for civilian/commercial use has also been developed. Military versions in production include transport, utility, reconnaissance and medical evacuation variants.

As of January 2024, more than 400 Dhruvs had been produced for domestic and export markets logging more than 340,000 flying hours.
