India has longstanding and wide-ranging cooperation with Russia in the field of defence.

India-Russia military technical cooperation has evolved from a simple buyer - seller framework to one involving joint research, development and production of advanced defence technologies and systems.

BrahMos Missile System, Joint development of the Fifth Generation Fighter Aircraft and the Multi Transport Aircraft, as well as the licensed production in India of SU-30 aircraft and T-90 tanks, are examples of such flagship cooperation.
