Overview

• The Defence Research & Development Laboratory (DRDL) conducted a 1,000-second scramjet engine ground test at the Scramjet Connect Test Facility (SCPT) in Hyderabad on April 25, 2025.
• The test marks a significant step toward the development of flight-ready hypersonic cruise missile systems, capable of sustained speeds exceeding Mach 5.
• This achievement builds on a 120-second scramjet combustor test conducted in January 2025, demonstrating progress in air-breathing propulsion technology.
• The successful test validated the long-duration combustor design and highlighted the capabilities of the newly built SCPT facility.
• Defence Minister Rajnath Singh emphasized the strategic importance of hypersonic technologies and praised the collaborative efforts of DRDO, industry, and academia.
