The HSTDV, based on hypersonic propulsion technologies, has been developed by the Defence Research and Development Organisation (DRDO), they said.
DRDO can develop a hypersonic missile with scramjet engine in next five years, which will have the capacity to travel at more than two kilometres per second.
The HSTDV performed on all parametres, including combustion chamber pressure, air intake and control guidance.
At 11.03 am, the Agni missile booster took the hypersonic vehicle to height of 30 km after which the latter separated. Thereafter, the vehicle’s air intake opened and that led to successfully firing of the test scramjet engine. The combustion lasted for more than 20 seconds with the vehicle achieving a speed of Mach 6. The vehicle performed successfully on all the pre-determined parametres including the ability to handle combustion temperatures of over 2500 degrees Celsius as well as air speed.
HSTDV is an unmanned scramjet demonstration aircraft for hypersonic speed flight. Besides its utility for long-range cruise missiles of the future, the technology has multiple civilian applications also. It can be used for launching satellites at low cost.
Only US, Russia and China had tested similar kind of technology.
Defence Minister Rajnath Singh congratulated the DRDO over the successful test flight of the HSTDV, calling it a “landmark achievement”
“I congratulate to DRDO on this landmark achievement towards realising PM’s vision of Atmanirbhar Bharat. I 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 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.
