Ursa Major provides flight-proven propulsion solutions for hypersonics, solid rocket motors, space mobility, and launch applications. Headquartered in Berthoud, Colorado, with additive manufacturing operations in Youngstown, Ohio, the company leverages advanced production techniques and flexible architectures to serve land, air, sea, and space domains. Recent milestones include multiple successful flights of its hypersonic engines and tactical missiles, completion of tests for space-propulsion systems, and the addition of industry veterans Ronald Sugar and Gilman Louie to its board. Through the first three quarters of 2025, Ursa Major secured more than $115 million in bookings from government and commercial customers such as the U.S. Department of Defense, the U.S. Air Force Research Laboratory, Stratolaunch, and BAE Systems. The fresh capital will be used to scale manufacturing capacity, accelerate production of throttleable, storable liquid-fueled hypersonic and space-based defense solutions, and expand solid-rocket-motor output. The company positions itself as a modern alternative to legacy defense suppliers, aiming to deliver capabilities faster and at lower cost.
