Venus Aerospace secures $90M to advance Rotating Detonation Rocket Engine
Venus Aerospace raises $90M Series B to develop its ultra-efficient Rotating Detonation Rocket Engine for hypersonic weapons and space vehicles.

Venus Aerospace, a company founded in 2020 by CEO Sassie Duggleby and CTO Andrew Duggleby, has raised $90 million in a Series B funding round. The company is developing an ultra-efficient Rotating Detonation Rocket Engine (RDRE) that has garnered significant interest from the military and space industries. The RDRE was initially conceptualized as a more efficient way to launch rockets, but its complex physics made it difficult to understand and control.
Recent advancements in 3D printing and simulations have made it possible to develop a working RDRE. Venus Aerospace successfully demonstrated its engine in flight last year, which led to a change in the company's plans. "What happened when we flew last May is the world looked at us and said, 'oh my gosh, you have a working RDRE, would you sell us one?' And that wasn't what we were expecting," Sassie Duggleby told TechCrunch.
The company is now focused on developing hypersonic weapons and high-speed space vehicles that appeal to the military. The funding round, led by Mercury Fund, will be used to fund testing and development work on specific vehicle designs with potential customers. "Our propulsion architecture combines efficiency, throttling, reusability and manufacturability in a way that customers need for real defense and space missions," Andrew Duggleby said in a statement.
The RDRE creates a continual supersonic wave of combustion that rotates through a circular channel, wasting less propellant than traditional rocket engines. Venus Aerospace has conducted 600 tests, firing its engine for up to 32 seconds. The company plans to build a new, larger test stand to enable longer engine burns of at least six to 15 minutes.
Why this matters: The development of the Rotating Detonation Rocket Engine has significant implications for the aerospace industry. With its ultra-efficient design, the RDRE could enable the creation of more powerful and sustainable hypersonic vehicles, which could transform the military and space sectors. For developers and businesses, this technology presents opportunities for innovation and growth, particularly in the areas of defense and space exploration.
However, questions remain about the scalability and reliability of the RDRE, as well as its potential applications beyond the military and space industries. As Venus Aerospace continues to advance its technology, it will be crucial to address these questions and explore the broader implications of this emerging technology.
