DRDO Achieves Breakthrough with Over 1,000 Seconds of Scramjet Combustor Testing

The Defence Research & Development Laboratory (DRDL), a Hyderabad-based facility under the Defence Research and Development Organisation (DRDO), has achieved a significant breakthrough in the development of hypersonic weapon technology. On 25 April 2025, DRDL successfully conducted the ground testing of an Active Cooled Scramjet Subscale Combustor for a duration exceeding 1,000 seconds. The testing took place at the newly established Scramjet Connect Test Facility in Hyderabad.

This achievement follows an earlier test conducted in January 2025, where the scramjet combustor was tested for 120 seconds. The successful long-duration testing brings the system closer to readiness for full-scale flight-worthy combustor evaluations.

Understanding the Hypersonic Cruise Missile Programme

Hypersonic Cruise Missiles represent a transformative class of weapon systems capable of travelling at speeds greater than five times the speed of sound, exceeding 6,100 kilometres per hour. These missiles rely on air-breathing propulsion systems, where supersonic combustion plays a pivotal role in sustaining long-duration flight conditions.

The recent successful ground test validates not only the scramjet combustor’s design but also the operational efficacy of the state-of-the-art testing facility. It stands as a testament to the collaborative efforts between DRDO, Indian industry partners, and academic institutions, further strengthening the foundation of India’s Hypersonic Cruise Missile Development Programme.

Government and Scientific Leadership Celebrate the Achievement

Raksha Mantri Shri Rajnath Singh extended his congratulations to DRDO, industry partners, and academia, describing the achievement as a reflection of the Government’s steadfast commitment to realising critical hypersonic weapon technologies for national security.

Dr Samir V Kamat, Secretary of the Department of Defence R&D and Chairman of DRDO, also applauded the efforts of the scientific team. He specifically congratulated Shri U Raja Babu, Director General (Missiles & Strategic Systems), Dr GA Srinivasa Murthy, Director of DRDL, and their teams for successfully demonstrating supersonic combustion for over 1,000 seconds, a milestone involving cutting-edge technologies.

Conclusion

The successful test marks a significant step forward for India’s defence research capabilities. It demonstrates not only technological maturity in scramjet propulsion systems but also strengthens the nation’s pursuit of advanced hypersonic platforms. As DRDO continues to innovate in this domain, the results from the latest ground tests are expected to accelerate further developments in hypersonic flight and missile systems.
