Revolutionary rocket engine company Venus Aerospace raises $91 million to scale design
The funding will help Venus move its rotating detonation rocket engine from prototype to scalable systems for aircraft, satellites and future spacecraft.
- On Wednesday, Houston-based Venus Aerospace announced a $91 million Series B funding round to scale its Rotating Detonation Rocket Engine from prototype to production for defense and space applications.
- Venus shifted focus to defense and space after successfully completing the world's first flight test of a high-thrust RDRE in May 2025, which delivers 15 percent higher efficiency than conventional rockets.
- Across 600 tests, the engine has fired for 32 seconds at most, while customers require six to 15 minutes of burn time; engineers designed the system using 3D-printed components for scalable domestic manufacturing.
- CEO Sassie Duggleby called the investment "an important step" in maturing production, while Mercury Fund and Lockheed Martin Ventures praised the company's progress in manufacturing speed and supply chain management.
- Venus recently received a Texas Space Commission grant to build a larger test stand, supporting its long-term vision to power aircraft traveling up to Mach 6 and orbital transfer vehicles.

Revolutionary rocket engine company Venus Aerospace raises $91 million to scale design
Houston-based company Venus Aerospace announced today (June 8) the closing of its "Series B" financing round, which raised $91 million to evolve its rotating detonation rocket engine (RDRE) from functioning prototype to a scalable propulsion system with multiple applications. Venus completed a demonstration launch with its test vehicle in May 2025, accomplishing the first such flight from U.S. soil powered by an RDRE. At scale, the company envis…
