From Runway to Hypersonic Cruise
The Venus Detonation Ramjet (VDR) is a breakthrough engine that integrates the Venus Rotating Detonation Rocket Engine–the most efficient rocket engine ever flown–with air-breathing ramjet technology. The VDR is the most viable integrated solution to take you from take-off to hypersonic cruise. This is the holy grail of high-speed flight.
Affordable by Design
The VDR has been engineered from day one to deliver breakthrough performance at lower cost. Reusable and built with no moving parts, it’s produced using 3D printing and other advanced manufacturing techniques with standard materials instead of expensive exotic alloys.
The result is a propulsion system that’s affordable to manufacture, operate, and maintain—supported by a resilient supply chain.
Next-generation technology
Compact, hyper-efficient, and built to scale, the VDR is redefining the limits of defense and commercial high-speed flight. In defense applications, its efficiency, flexibility, and low signature enable new capabilities for high-speed munitions and advanced vehicles—both crewed and uncrewed—at dramatically lower cost.
In the future, this same propulsion system will enable commercial high-speed travel, connecting the world faster than ever before. Reusable, affordable, and efficient, the VDR moves the frontiers of aerospace and defense.
