The missile is called BrahMos which is equipped with an indigenous seeker developed by BrahMos Aerospace and DRDO, and manufactured by state-owned Electronics Corporation of India. The earlier version of BrahMos missiles were fitted with Russian-supplied seekers for terminal guidance. India had been working for a couple of years on developing a new indigenous seeker that eventually replaced the Russian-made system.
The BrahMos missile program is a joint venture between India’s DRDO and Russian rocket design bureau NPO Mashinostroyeniya. India supplies the BrahMos’ inertial navigation system and fire control system, and Russia the ramjet propulsion system and seeker (replaced with the Indian system in later versions).
