♦ Defence Research and Development Organisation (DRDO) achieved a significant milestone in Scramjet Engine Development by conducting Active Cooled Scramjet Subscale Combustor ground testing for over 1,000 seconds on 25 April 2025.

♦ The Defence Research and Development Laboratory which is a Hyderabad-based laboratory of DRDO, conducted the ground testing at the newly built state-of-the-art Scramjet Connect Test Facility.

♦ The ground test is in continuation of the earlier test reported for 120 seconds in 2025 January.

♦ With the successful test, the system will be soon ready for full scale flight worthy combustor testing.

♦ Hypersonic Cruise Missile is a class of weapons that can travel more than five times the speed of sound for long duration and is powered by Air breathing engine.

♦ Air breathing propulsion systems, having supersonic combustion, plays a critical role for long-duration cruise conditions.

♦ This test validates the design of long duration scramjet combustor as well as test facility.
