Congratulations DRDO


Congratulations DRDO for successful flight of HSTDV




Today Indians are appreciating DRDO [ defense research and development organization ] for successful flight of HSTDV [ Hyperaonic Technology Demonstration Vehicle ].

Our researchers and scientists developed a scramjet engine which helped the flight to achieve a speed six times the speed of sound.


Only few countries have such capability today, and India is one of them.


This is a proud moment for our country.


We should thanks our researchers and scientists for making us proud and we should also appreciate DRDO for their achievement.


Again India & Indians prove that we are best among all.


• Speed of sound  :- 343 m/s


What is HSTDV


HSTDV or Hypersonic Technology Demonstrater Vehicle is an aircraft for hypersonic speed flight.

It's a scramjet demonstration aircraft.

It's mainly developed and designed for long range and hypersonic cruise missiles.

It's also used for launching of small satellites at low cost.


Our Prime minister Narendra Modi specially appreciated DRDO for their achievement.



HSTDV, DRDO achievement, Narendra modi latest tweet


So proud of you Sir for making this project successful under your dynamic leadership. Kudos to the scientist fraternity for this tremendous achievement.


Mr. Rajnath singh congratulates DRDO.


The DRDO has today successfully flight tested the Hypersonic Technology Demonstrator Vehicle using the indigenously developed scramjet propulsion system. With this success, all critical  technologies are now established to progress to the next phase.

I congratulate Team 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.

What DRDO said on their achievement.


DRDO successfully flight tests Hypersonic Technology Demonstrator Vehicle

Posted On: 07 SEP 2020 2:56PM by PIB Delhi

Defence Research and Development Organisation (DRDO) has successfully demonstrated the hypersonic air-breathing scramjet technology with the flight test of Hypersonic Technology Demonstration Vehicle (HSTDV) at 1103 hours from Dr APJ Abdul Kalam Launch Complex at Wheeler Island, off the coast of Odisha today.

The hypersonic cruise vehicle was launched using a proven solid rocket motor, which took it to an altitude of 30 kilometres (km), where the aerodynamic heat shields were separated at hypersonic Mach number. The cruise vehicle separated from the launch vehicle and the air intake opened as planned. The hypersonic combustion sustained and the cruise vehicle continued on its desired flight path at a velocity of six times the speed of sound i.e., nearly 02 km/second for more than 20 seconds. The critical events like fuel injection and auto ignition of scramjet demonstrated technological maturity. The scramjet engine performed in a text book manner.

The parameters of launch and cruise vehicle, including scramjet engine was monitored by multiple tracking radars, electro-optical systems and Telemetry Stations. The scramjet engine worked at high dynamic pressure and at very high temperature. A Ship was also deployed in the Bay of Bengal to monitor the performance during the cruise phase of hypersonic vehicle. All the performance parameters have indicated a resounding success of the mission.

With this successful demonstration, many critical technologies such as aerodynamic configuration for hypersonic manoeuvers, use of scramjet propulsion for ignition and sustained combustion at hypersonic flow, thermo-structural characterisation of high temperature materials, separation mechanism at hypersonic velocities etc. were proven.   

Raksha Mantri Shri Rajnath Singh congratulated DRDO on this landmark achievement towards realising Prime Minister Narendra Modi’s vision of Atmanirbhar Bharat. He also spoke to the scientists associated with the project and congratulated them on this great achievement. India is proud of them, he added.

Secretary Department of Defence R&D and Chairman DRDO Dr G Satheesh Reddy congratulated all the Scientists, Researchers and other personnel related with HSTDV mission for their resolute and unwavering efforts towards strengthening Nation’s defence capabilities. On this successful demonstration, the country enters into the hypersonic regime paving way for advanced hypersonic Vehicles.
