India’s Defence Research and Development Organisation (DRDO) conducted maiden test of an indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV) from launch pad number-4 of Integrated Test Range (ITR) at Abdul Kalam Island off Odisha Coast.
It is an unmanned scramjet demonstration aircraft. It is designed to cruise at Mach 6 speed with scramjet engine.
Background: In 2008, DRDO stated that through HSTDV project idea was to demonstrate performance of a scram-jet engine at an altitude of 15 km to 20 km, is on. Thus under this project, DRDO developed a hypersonic vehicle that will be powered by a scram-jet engine.
Applications: HSTDV is dual-use technology thus with a scramjet engine, HSTDV can cruise at Mach 6 speed and can have multiple civilian applications. It can be used for launching satellites at low cost and can also be available for long-range cruise missiles of future.
Key Highlights of Test
Method: In test conducted, a missile mounted with technology demonstrator vehicle is launched and vehicle is released only after missile reaches a certain altitude and velocity.
Reason for launch: The launch of technology demonstrator vehicle was undertaken to prove a number of critical technologies for futuristic missions and to validate several technologies including HSTDV.
Analysis: The HSDTV was supposed to fire and fly on its own after being carried to an altitude of around 30-40 km by solid rocket motor of an Agni-I ballistic missile in test but after launch, Agni-I booster went into an uncontrolled mode and could not achieve desired altitude. Some technologies have been validated while some remained inconclusive of which data is being analysed.
Scram-jet system v/s Ram jet system
In scram-jet technology, fuel combustion takes place in a chamber in missile at supersonic speeds while in a ram jet system, the system collects air it needs from atmosphere during flight at subsonic speeds and propellants burn in combustion chamber.

India has successfully carried out night user trial of Agni-I short-range nuclear-capable ballistic missile. The test flight was conducted by Indian Army’s Strategic Forces Command off Abdul Kalam Island in Bay of Bengal, off the coast of the Indian state of Odisha. The test was second known nighttime trial of Agni-I since its first such successful test in April 2014.
Agni-I is short range nuclear capable surface-to-surface ballistic missile. It is first missile of the Agni series launched in 1983. It was developed by premier missile development laboratory of DRDO in collaboration with Defence Research Development Laboratory and Research Centre Imarat and integrated by Bharat Dynamics Limited, Hyderabad.
It weighs 12 tonnes and is 15-metre-long. It is designed to carry payload of more than one tonne (both conventional and nuclear warhead). It is single stage missile powered by solid propellants. It can hit a target 700 km away. Its strike range can be extended by reducing the payload. It can be fired from road and rail mobile launchers.
It is equipped with sophisticated navigation system which ensures it reaches the target with a high degree of accuracy and precision. The missile already has been inducted into armed forces. Since its induction it has proved its excellent performance in terms of range, accuracy and lethality. It is also claimed to be a part of India’s minimum credible deterrence under No first to use policy.
