India developed an indigenous seeker for Brahmos for the first time.
Brahmos is the world’s fastest and most formidable anti-ship cruise missile. This marks a big achievement and breakthrough for the supersonic missile as this is the first time the country has developed a seeker for a missile of this calibre and class. The missile travels at speeds of Mach 2.8 to 3.0, which is being upgraded to Mach 5.0. The Land-launched and ship-launched versions are already in service, with the air and submarine-launched versions currently in the testing phase. An air-launched variant of BrahMos appeared in 2012. A hypersonic version of the missile, BrahMos-II, is also presently under development with a speed of Mach 7-8 to boost aerial fast strike capability. It is expected to be ready for testing by 2020.
