The Ministry of Defence on 9 May 2026 confirmed that the Defence Research and Development Organisation (DRDO) has achieved a continuous ground test run of more than 1,200 seconds, that is over 20 minutes, of its active-cooled scramjet combustor at the DRDO Defence Research and Development Laboratory in Hyderabad. The Ministry described the test as a "path-breaking milestone" that has placed India at the forefront of advanced aerospace capabilities and hypersonic technologies. A scramjet, or supersonic combustion ramjet, is an air-breathing engine that uses atmospheric oxygen for combustion at hypersonic speeds beyond Mach 5, eliminating the need to carry heavy oxidisers on board and thereby enabling longer ranges and heavier payloads in cruise missiles and future aerospace vehicles. The 1,200-second sustained run validates the engine's ability to handle the extreme thermal loads experienced at hypersonic speeds and is the longest endurance run achieved by India in this class. The success comes alongside two other DRDO validations announced in the preceding days: a flight trial of an advanced Agni missile equipped with Multiple Independently Targeted Re-Entry Vehicle (MIRV) technology off the Odisha coast and a maiden trial of the Tactical Advanced Range Augmentation glide weapon system. Together they signal Indias maturing capability across the strategic deterrence and hypersonic spectrum and feed into the Atmanirbhar Bharat objective of self-reliance in defence research. Hypersonic cruise missile programmes are currently being pursued only by a small group of countries including the United States, Russia and China.

Practice MCQ from this story
SolveTap an option below. Correct or incorrect feedback appears instantly.
With reference to the DRDO scramjet ground test confirmed by the Ministry of Defence on 9 May 2026, consider the following statements: 1. The active-cooled scramjet combustor achieved a continuous ground test run of more than 1,200 seconds. 2. A scramjet is an air-breathing engine that uses liquid oxygen carried on board as the oxidiser for combustion at hypersonic speeds. Which of the statements given above is/are correct?
Statement 1 is correct - the active-cooled scramjet combustor sustained a continuous ground run of more than 1,200 seconds. Statement 2 is incorrect - the defining feature of a scramjet (supersonic combustion ramjet) is that it uses atmospheric oxygen captured at supersonic flow speeds, NOT liquid oxygen carried on board. This is what eliminates the need to carry heavy oxidisers and enables longer range and heavier payloads.

Frequently asked questions
What is a scramjet engine?
A scramjet, or supersonic combustion ramjet, is an air-breathing engine that uses atmospheric oxygen for combustion at hypersonic speeds above Mach 5, eliminating the need to carry oxidisers on board and enabling longer ranges and heavier payloads.
What achievement did DRDO confirm on 9 May 2026?
DRDOs active-cooled scramjet combustor achieved a continuous ground test run of more than 1,200 seconds at Hyderabad, the longest endurance run achieved by India in this class.
Why is this milestone strategically significant?
Sustained scramjet performance is the technological foundation of hypersonic cruise missiles, currently fielded only by a small group of countries; the test advances Indias hypersonic and aerospace capability and supports the Atmanirbhar Bharat objective in defence.
What other strategic validations preceded this scramjet test?
DRDO had also flight-tested an advanced Agni missile with MIRV (Multiple Independently Targeted Re-Entry Vehicle) technology off the Odisha coast and conducted a maiden trial of the Tactical Advanced Range Augmentation glide weapon system in the preceding days.
