Venus Aerospace Successfully Tests Next-Gen Rocket Engine at Spaceport America
- On May 14, 2025, Venus Aerospace successfully completed the inaugural U.S. Trial of its innovative rotating detonation rocket engine at a launch facility in New Mexico.
- This event followed decades of research on RDRE technology and five years of Venus Aerospace’s development to make the engine flight-ready and scalable.
- The engine provides 2,000 pounds of thrust, runs reliably outside the lab, and integrates with Venus’s VDR2 air-breathing ramjet to enable sustained hypersonic flight above Mach 6.
- Co-Founder Andrew Duggleby highlighted rotating detonation as a significant long-awaited advancement in performance, while CEO Sassie Duggleby described this achievement as the culmination of five years of dedicated effort.
- This successful test represents a significant advancement in U.S. Aerospace technology, accelerating the development of hypersonic vehicles with plans for full-scale propulsion trials and efforts to reestablish American dominance in high-speed aviation.

Venus Aerospace completes historic U.S. hypersonic engine flight test – SatNews
Venus Aerospace, earlier this month, successfully completed the first U.S. flight test of a next-generation rocket engine: a Rotating Detonation Rocket Engine (RDRE). This milestone marks a breakthrough in American aerospace, with a design ultimately aimed at enabling vehicles to travel four to six times the speed of sound from a conventional runway. Theorized since the 1980s, a high-thrust RDRE capable of practical application has never been fl…
