Israel Aerospace Industries' Lahav division has received a follow-on contract to continue an avionics upgrade on the Indian armed forces' Hindustan Aeronautics Dhruv advanced light helicopters.

An initial award covered work on 50 of the twin-engined rotorcraft, with the latest deal concerning a further 150 examples. Work is already under way.

Benjamin Cohen, vice-president and general manager of the Lahav division, says the follow-on contract includes Dhruvs that are used for both land-based and maritime missions.

Cohen says modification kits are produced in Israel, before being shipped to India. "The upgrade kits are made according to the mission of the helicopter," he notes.

Elements of the enhancement package include installing a full glass cockpit with a moving map display. These features are part of an integrated architecture display system, which Lahav says is aimed at optimising the operational performance of the helicopter and its pilots.
