Ursa Major Successfully Completes SRM Manufacturing Pathfinder Program with U.S. Navy and OSC

DENVER—(July 7, 2026) — Ursa Major has completed its Solid Rocket Motor (SRM) Manufacturing Pathfinder Program conducted in partnership with the U.S. Navy and Office of Strategic Capital (OSC).

Over the course of the program, Ursa Major achieved several key technical and manufacturing milestones. The Company designed, manufactured, and successfully static-fired an HLG 10-inch SRM prototype. Ursa Major also developed and characterized a proprietary propellant for the motor. The motor met all performance objectives and burn duration requirements, achieving a technical and manufacturing foundation for future U.S. Navy systems that require a 10” diameter SRM.

“In partnership with the Navy and OSC, we translated capital into real, measurable outcomes that scaled manufacturing capacity and advanced a production model built for speed and surge,” said Chris Spagnoletti, CEO of Ursa Major. “This program validated that when the government invests in companies that are used to doing more with less, companies that prioritize execution, innovation, and manufacturability from day one, you get capability that matters on timelines that matter. That’s how we rebuild the defense industrial base, and how we deliver credible, scalable capability to the joint force.”

With this program, Ursa Major invested heavily in facility scaling and process improvements to expand its SRM production capabilities. Program milestones were intentionally structured to act as a pathfinder for larger systems. The program also enabled significant refinement of the Company’s common, modular manufacturing process, known as Lynx, which uses Highly Loaded Grain and enables subsystem commonality across components. This approach reduces tooling costs and lead times while increasing flexibility and scalability across multiple motor variants. As a result, Ursa Major is ready to scale to support the U.S. Navy’s demand for solid rocket motors.
