India and Russia are most likely to sign another mega defence deal soon to jointly develop Medium-Range Surface-To-Air Missile System (MR-SAM) for the Indian Army. As of now, the contract negotiation committee has virtually sealed the joint development through collaboration between DRDO and Israeli Aerospace Industries, where Defence PSU Bharat Dynamics, in turn, will undertake bulk production of the systems in India. As for the initial Army order for one regiment of the MR-SAM systems, with their multi-function surveillance and threat tracking radars as well as weapon control systems, it would cost over Rs 9,000 crore.
