The first successful test of a Hypersonic Technology Demonstration Vehicle or HSTDV, which can be used for futuristic missile system and aircraft, was conducted on September 7 off the coast of Odisha. So far, Russia, China & the US have been developing hypersonic test vehicles. A hypersonic cruise missile, once developed, can defeat any Chinese defensive system, scientists said Defence research organisation DRDO, which conducted the test. DRDO called it a "historic mission", which was "a giant leap in indigenous defence technologies and significant milestone" towards a Self-Reliant & Empowered India.
