The BRAHMOS supersonic cruise missile has successfully tested its propulsion system, airframe, power supply, and other main indigenous components.
BRAHMOS is a cooperative venture between India's Defence Research and Development Organisation (DRDO) and Russia's National Propulsion Organization (NPOM).
The rivers Brahmaputra and Moskva are named Brahmos.
It's a two-stage air-to-surface missile with a range of roughly 300 kilometers (solid propellant engine in first stage, liquid ramjet in second).
However, India's entrance into the Missile Technology Control Regime (MTCR) has increased the BRAHMOS missile's range to 450-600 kilometers, a little increase above the present MTCR-capped range of 300 kilometers.
With a weight of 2.5 tonnes, Brahmos is the largest weapon ever deployed aboard a Su-30 MKI fighter plane.
Brahmos is a multiplatform, multi-capability missile that can be launched from land, air, and sea. It has pinpoint accuracy and can be used at any time of day or night, regardless of weather conditions.
It works on the "Fire and Forgets" principle, which means it doesn't need any additional instructions after it's launched.
Brahmos is one of the fastest cruise missiles in service today, with a top speed of Mach 2.8, or three times the speed of sound.
