fires Hypersonic 
Technology 
Demonstrator Vehicle
INTRODUCTION
 India conducted a successful test flight of the 
indigenously developed Hypersonic Technology 
Demonstrator Vehicle (HSTDV), joining an elite 
group of countries i.e. the US, Russia and China, 
who possess the technology.

USES
 The HSDTV has a range of uses, including 
 Missiles of the future for air defense
 Surveillance and reconnaissance besides in the 
development of energy-efficient
 Low cost and reusable satellite-launch vehicles

TEST DETAILS
 The cruise vehicle separated from the launch 
vehicle and the air intake (channel) 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 2 km/s for more than 20s.

NUCLEAR DETERRENCE CAPABILITY 
 It comes in the wake of India acquiring the 
ability to use a missile to shoot down a 
satellite in space last year and 
demonstrating that the country had 
acquired submarine based nuclear 
deterrence capability in 2018.

INDIA CHINA RELATION
 The tensions are at unprecedented levels 
with thousands of troops facing off across 
the borders.
 The success flight test will help India to 
defense against such countries.

TECHNOLOGY
 The test was done using the indigenously developed scramjet propulsion system. 
 With this success, all critical technologies are now established to progress to the next 
phase

SELF RELIANT INDIA
 The test will enhance prime minister 
Narendra Modi’s “self reliant" India 
campaign that aims to transform Asia’s 
third largest economy into a 
manufacturing hub.

NEXTGEN HYPERSONIC VEHICLES
 DRDO with this mission has demonstrated 
capabilities for (developing and delivering) 
highly complex technology that will serve as 
the building block for NextGen Hypersonic 
vehicles in partnership with industry.

FIRST HSTDV
 Last year India first tested the HSTDV.
 The test was conducted from the Dr. APJ 
Abdul Kalam Launch Complex at Wheeler 
Island, off the coast of Odisha.

CRITICAL TECHNOLOGIES
 With this successful demonstration, many 
critical technologies such as 
 Aerodynamic configuration for hypersonic 
maneuvers
 use of scramjet propulsion for ignition and 
sustained combustion at hypersonic flow 
 Thermo-structural characterization of high 
temperature materials
 Separation mechanism at hypersonic 
velocities" were tested
