The HAL Rudra also known as ALH-WSI, is an armed version of the HAL Dhruv utility helicopter which is designed and produced by the Indian aerospace manufacturer Hindustan Aeronautics Limited (HAL).

The HAL Dhruv is a utility helicopter designed and developed by Hindustan Aeronautics Limited (HAL) in November 1984. The helicopter first flew in 1992; 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 name comes from a Sanskrit origin word dhruv which means unshakeable or firm.
