New Delhi: India on Monday successfully flight tested the indigenously-developed hypersonic technology demonstrator vehicle (HSTDV). According to officials, the vehicle is expected to power futuristic long-range missile systems and aerial platforms. The HSTDV has been developed by the Defence Research and Development Organisation (DRDO). It is based on hypersonic propulsion technologies, Defence Minister Rajnath Singh congratulated the DRDO over the successful test flight of the HSTDV, and marked it as a "landmark achievement" The @DRDO_India has today successfully flight tested the Hypersonic Technology Demontrator Vehicle using the indigenously developed scramjet propulsion system. With this success, all critical technologies are now established to progress to the next phase. \u2014 Rajnath Singh (@rajnathsingh) September 7, 2020 "I congratulate to DRDO on this landmark achievement towards realising PM's vision of Atmanirbhar Bharat.\u00a0I spoke to the scientists associated with the project and congratulated them on this great achievement. India is proud of them," he tweeted. A DRDO official said, with the successful test flight of the HSTDV, India has demonstrated capabilities for highly complex technology that will serve as the building block for next-generation hypersonic vehicles in partnership with the domestic defence industry. The HSTDV powers cruise missiles and operates on scramjet engines which can attain the speed of around Mach 6 which is far better than ramjet engines, the officials said.
