It is expected to be ready for testing by 2017. The name BrahMos is a portmanteau formed from the names of two rivers, the Brahmaputra of India and the Moskva of Russia. In 2016, as India became a member of the Missile Technology Control Regime (MTCR), India and Russia are now planning to jointly develop a new generation of BrahMos missiles with 600 km-plus range and an ability to hit protected targets with pinpoint accuracy.
