Ursa Major is the leading independent rocket propulsion provider and a critical player in building the defense industrial base in the United States. As the first American company to fire an oxygen-rich staged combustion engine-a milestone previously only achieved by Russian engine-makers-Ursa Major provides reusable, high-performing propulsion systems to commercial space enterprises, defense contractors, and the Department of Defense for launch, hypersonics, and national security missions. The company employs the country's leading propulsion experts at its one-of-a-kind headquarters in Berthoud, Colorado, which houses engineering, manufacturing, and testing all in one campus. Manufactured using 3D printing for scalable production, Ursa Major propulsion systems save customers an average of five years and $50 million compared to building propulsion in-house.
