Ursa Major has raised $100 million to enhance its defense capabilities, focusing on propulsion systems for hypersonic vehicles and missile defense, highlighting a strategic shift in the aerospace sector.

Strategic Shift Towards Defense

Ursa Major, a key player in aerospace, has successfully secured $100 million in new capital, marking a significant strategic shift towards enhancing defense capabilities. This influx of funds is largely directed towards the development of advanced propulsion systems needed for hypersonic vehicles and missile defense, showcasing the company’s response to growing demands from U.S. defense agencies and strategic partners such as Stratolaunch and BAE Systems [1][2].

Funding and Investor Dynamics

The $100 million Series E funding round, closed on 18 November 2025, was led by Eclipse Ventures, with participation from notable investors including Woodline Partners, Principia Growth, XN, and Alsop Louie Partners. This round also included $50 million in debt commitments, setting the stage for Ursa Major to accelerate its production capabilities and meet military needs [1][3][4]. The company’s valuation has now reached $600 million, reflecting investor confidence in its strategic direction [5].

Addressing Industrial and National Security Needs

With this new capital, Ursa Major plans to scale its manufacturing operations to deliver advanced propulsion solutions at an industrial scale. The focus is on building systems capable of supporting hypersonic flight and space-based defense initiatives, aligning with the Pentagon’s Golden Dome architecture. CEO Dan Jablonsky emphasized that this investment empowers the company to solve critical industrial base and national security challenges for the United States and its allies [1][2][6].

Impact on Aerospace and Defense Sector

The raised funds allow Ursa Major to enhance its capabilities in satellite propulsion and missile defense interceptors, further cementing its role in defense technology innovation. This move signifies a broader trend in the aerospace sector towards military applications, as companies pivot from the commercial launch market to meet defense demands.
