Advanced propulsion developer Ursa Major has secured $100 million in Series E equity financing and an additional $50 million in debt funding, giving the U.S. manufacturer fresh capital as it accelerates production of hypersonic engines, solid rocket motors and space mobility technologies.
The equity round was led by Eclipse, with participation from new and existing investors including Woodline Partners, Principia Growth, XN, Alsop Louie Partners and other institutional backers.
Ursa Major, which relies heavily on additive manufacturing, positions its propulsion systems as a faster and more cost-effective alternative to traditional suppliers amid what the company describes as critical shortfalls in the U.S. industrial base.
“Ursa Major is doing what few others in defense have achieved — scaling manufacturing and supply chains to deliver hypersonic systems and advanced propulsion at an industrial scale,” said Lior Susan, founding partner at Eclipse. “We’re proud to support their mission to strengthen the U.S. and allied industrial base with real capability, built here and built now.”
The company recently added industry veterans Ronald Sugar and Gilman Louie to its board as it ramps up operations.
Since its last funding round, Ursa Major has completed several successful flight tests of its hypersonic engines and tactical missile systems, milestones the company says demonstrate technical readiness for wider deployment.
With expanding government and commercial contracts and new capital in hand, Ursa Major is seeking to deepen its role in the rapidly growing hypersonic and space-based defense sector.
