What Venus Aerospace does
Venus Aerospace is a Houston, Texas-based propulsion technology company founded in 2020 by Sassie Duggleby (CEO) and Andrew Duggleby (CTO). It develops the Rotating Detonation Rocket Engine (RDRE), a propulsion architecture the company describes as the first fundamental improvement in rocket engine technology since the Apollo Program, generating thrust via supersonic detonation waves traveling around an annular combustor. Venus has extended this core technology into the Venus Detonation Ramjet (VDR) family — including the VDR2 2,000 lb thrust engine — which integrates the RDRE with air-breathing ramjet technology to provide a single-engine solution from runway takeoff to Mach 6 hypersonic cruise.
The company's revenue model is multi-pronged: government R&D contracts and non-dilutive grants from agencies including NASA Marshall Space Flight Center, DARPA, the U.S. Air Force (AFWERX), and the Texas Space Commission; strategic and venture capital partnerships (e.g., Prime Movers Lab, Airbus Ventures, America's Frontier Fund, Trousdale Ventures, Lockheed Martin Ventures); and prospective future direct sales or licensing of RDRE/VDR propulsion systems for space launch upper stages, hypersonic drones, missiles, defense munitions, and the Stargazer M4 Mach 4 commercial passenger aircraft concept. Go-to-market is enterprise sales through direct government program offices, defense primes, and aerospace OEMs, supported by visible test infrastructure at Spaceport Houston and Spaceport America, where Venus completed the first-ever U.S. high-thrust RDRE flight on May 14, 2025.
The company has raised more than $106 million in private funding across rounds, including a $20M Series A in April 2022 (led by Prime Movers Lab), strategic investment from Lockheed Martin Ventures in October 2025, and additional capital from America's Frontier Fund, Airbus Ventures, and other financial backers. As of late 2025 Venus has 51–100 employees, holds multiple patents on RDRE architecture and additive manufacturing (3D printing and Directed Energy Deposition) processes, and pursues headcount growth to advance its flight test program.

Venus Aerospace product offering
Product offeringCore offering
Venus Aerospace designs, manufactures, and sells advanced propulsion systems based on its proprietary Rotating Detonation Rocket Engine (RDRE) and Venus Detonation Ramjet (VDR) technologies. Its products target defense, space launch, and future commercial hypersonic flight applications, including munitions, drones, upper stages, landers, and high-speed passenger aircraft. The company also licenses its detonation engine IP to other aerospace and defense customers.
Product overview
Venus Aerospace offers a portfolio of propulsion technologies built around its proprietary Rotating Detonation Rocket Engine (RDRE) and Venus Detonation Ramjet (VDR) systems. The RDRE serves as the core rocket engine technology providing 15% greater efficiency than legacy systems through supersonic detonation waves. The VDR integrates the RDRE with air-breathing ramjet technology for seamless operation from runway takeoff through hypersonic cruise. The VDR2 is a specific 2000 lb thrust engine variant enabling Mach 0 to Mach 6 operation. These propulsion systems are designed to power the Stargazer hypersonic aircraft concept (Mach 9) and Stargazer M4 commercial passenger aircraft (Mach 4), with supporting flight test drone platforms for technology validation.
