Former NASA deputy administrator Pam Melroy joined Venus’s board a few months after the 2024 flight demo, signaling high-level support for the technology.

A May flight test of a 2,000-pound-thrust RDRE launched from Spaceport America in New Mexico marked notable milestones alongside leadership appointments.

Regulatory developments loom, with the FCC Space Modernization Order vote expected later this month to reform satellite licensing and support rapid space activities.

CTO Andrew Duggleby describes the RDRE’s differentiators as a blend of efficiency, throttling, reusability, and manufacturability, with a focus on turning progress into reliable propulsion systems.

Venus Aerospace has secured funding to scale its rotating detonation rocket engine (RDRE) toward production, supporting engine development and manufacturing while moving from flight testing to operational deployment.

The capital will be used to grow the team, expand production capabilities, and fund follow-on demonstration flights aimed at creating a single RDRE architecture suitable for multiple applications, including military, in-space propulsion, and high-speed aviation.

After pivoting from clean-flying hypersonic passenger jets, Venus is focusing on hypersonic weapons propulsion and high-speed space vehicles for defense and space missions, driven by market interest following a 2024 RDRE demonstration.

Venus says its RDRE is about 15% more efficient than conventional engines and can throttle thrust while using liquid propellants, enabling long-term storage and longer missions with reduced boil-off.

A May 2025 test flight marked the first US soil, large-scale RDRE-powered launch, and Venus envisions uses ranging from Mach 6 aircraft to orbital transfer vehicles and lunar landing engines.

Industry momentum for RDRE is growing, with investments and demonstrations from Stellar Alpina, Juno Propulsion, Astrobotic Technology, and JAXA.

Venus was founded in 2020 and has state support from Texas, including a $3.9 million grant to build a rocket engine test facility in Houston.

The May 2025 milestone of completing the first US RDRE test flight boosted customer and DoD interest, fueling the latest funding round.
