Aerospace and defense firm Ursa Major Technologies has announced the successful closing of a $100 million Series E financing round, complemented by $50 million in debt commitments. The investment comes as the company simultaneously announced over $115 million in bookings through the first three quarters of 2025, signaling robust momentum across both government and commercial sectors.
Investors in the round include new participants and long-standing backers of the company. Led by Eclipse, the funding was joined by firms including Woodline Partners, Principia Growth, XN, and Alsop Louie Partners, among others. According to the company, the new capital injection will accelerate manufacturing and production across its key product lines: hypersonics, solid rocket motors, and space mobility systems.
Ursa Major’s bookings of more than $115 million reflect contracts that span both commercial and defence domains, involving organisations such as the U.S. Department of Defense, the U.S. Air Force Research Laboratory, Stratolaunch, and BAE Systems. These orders underscore the company’s ability to secure commitments for advanced propulsion and defence-relevant systems.
With the fresh funding, Ursa Major plans to address urgent industrial base needs in the United States and among allied nations. The company will fast-track its throttleable, storable liquid-fueled hypersonic engines, space-based defence solutions, and scale up its solid rocket motor and sustained space mobility manufacturing capacity. By positioning itself to deliver high-performance propulsion systems faster and more cost-effectively than traditional legacy suppliers, Ursa Major aims to be a critical contributor to national security and industrial base renewal.
The strategic board is augmented by the appointment of Ronald Sugar and Gilman Louie, joining existing leadership to support the company’s growth trajectory. Alongside the new capital, Ursa Major has already achieved flight operations of its hypersonic engines and tactical missiles, and has progressed its solid rocket motor programmes.
Industries across land, air, sea and space are adapting rapidly to new propulsion needs. Ursa Major, headquartered in Berthoud, Colorado with additive-manufacturing operations in Youngstown, Ohio, states that it leverages advanced production techniques and flexible architecture to produce scalable, flight-proven systems for diverse missions. The company emphasises that this funding will enable the scaling of manufacturing and production to meet a faster timeline for delivery of critical capabilities in all domains.
