Venus says its rotating detonation rocket engine is flight-proven, about 15% more efficient than conventional rocket-engine architectures, and designed to be reusable, throttleable, and manufacturable through domestic supply chains—addressing range, performance, and production gaps in defense and space. The $91 million Series B led by Mercury Fund is intended to move that technology from a successful high-thrust flight demonstration toward deployable, scaled propulsion systems.
