"The helicopter has already reached Kathmandu and it will be handed over tomorrow," official sources said.
The chopper is manufactured by state-owned aerospace and defence company Hindustan Aeronautics Ltd.
The Mark-3 is the latest version of the original Dhruv helicopter and comes equipped with Shakti engines, new electronic warfare (EW) suite and warning systems, automatic chaff and flare dispensers and improved vibration control system.
The helicopter, which can cost anywhere between Rs 60-80 crore, is currently exported to at least three other countries, including the Maldives and Ecuador.
