DRDO Scramjet Engine: The Defence Research and Development Organisation (DRDO) reached an important achivement on Friday when it successfully finished a long ground test of an Active Cooled Scramjet Subscale Combustor. The test went on for more than 1,000 seconds and took place at the brand-new Scramjet Connect Test Facility (SCPT) in Hyderabad.
This achievement is a big step for India’s hypersonic weapon technology program. DRDO’s Defence Research and Development Laboratory (DRDL), which is based in Hyderabad, led the test.
According to ET, in their official statement DRDO said “Defence Research & Development Laboratory (DRDL), a Hyderabad-based laboratory of Defence Research and Development Organisation (DRDO) has achieved a significant milestone in the field of Hypersonic Weapon Technology. DRDL has conducted long duration Active Cooled Scramjet Subscale Combustor ground testing for more than 1000 seconds duration at the newly built state of art Scramjet Connect Test Facility (SCPT) at Hyderabad on 25th April 2025.”

This latest success builds on another important test that happened in January 2025, which lasted 120 seconds. DRDO said, “With today’s successful test, the system will be soon ready for full scale flight worthy combustor testing.”
Defence Minister Rajnath Singh shared his happiness over the success. He congratulated DRDO, its partners in industries, and universities for this big achievement. He said, “today’s success reflects our strong commitment in realizing critical Hypersonic Weapon Technologies for the nation.”
The DRDO explained that Hypersonic Cruise Missiles (HCM) can travel faster than five times the speed of sound, which means more than 6100 kilometers per hour, and they can keep flying at that speed for a long time. These missiles use special engines called air-breathing engines where combustion happens at supersonic speeds. This new test not only proved that the scramjet combustor design works but also showed that the new test facility in Hyderabad is ready for even bigger tasks in the future.

DRDO also said that this success was not the work of one group alone. Many DRDO labs, people from the industry, and academic experts all came together to make it happen. In their statement, they said, “It is an outcome of an integrated effort put by the DRDO labs along with industry and academia and paves a strong base for nation’s Hypersonic Cruise Missile Development Programme.”
