India tested the Hypersonic Technology Demonstrator Vehicle (HSTDV) which proved Indian technical capabilities to produce hypersonic missiles. Currently, hypersonic missiles are considered as the most advanced defense technology. To date, only four nations US, Russia, China, and now India have successfully tested it while other nations are still trying to catch up.
Any missile that flies beyond Mach 5 or more than 6100 kilometers per hour is called hypersonic missiles. Those missiles rely on their speed and agility to overcome enemy defenses as they can reach speeds comparable to ballistic missiles while maintaining a much stealthier flight path.
To date, only Russian Avangard hypersonic glide vehicle (HGV) has entered operational service in large numbers. Avangard is launched from UR-100UTTKh ICBMs and it flies at speed of Mach 25-27 or 11,200 kilometers per hour. This system was designed to defeat any futuristic US missile defense and Russia brands it as invulnerable to any missile defenses on earth.
hypersonic missile system is called Common-Hypersonic Glide Body (C-HGB) which is still in development and their first footage was released to media in March 2020. The US Hypersonic missiles will be flying at speed of Mach 17 or 2100 kilometers per hour. Like the Russian Avangard, American C-HGB will have intercontinental range.
Chinese Hypersonic glide vehicle is called DF-ZF which entered operational service in 2019, however, it is still being tested and refined. DF-ZF is fired using a DF-17 ballistic missile which was specifically designed for carrying hypersonic glide vehicles. Chinese
DF-ZF can reach up to Mach 10 or 12,300 kilometers per hour. Chinse hypersonic missiles are of medium-range and are designed to attack US aircraft carrier task forces.
