The 400-acre Facility Expands Capacity for Large-Article SRM Test, Qualification, and Readiness
WELD COUNTY, Colo., Sept. 10, 2025 /PRNewswire/ — Ursa Major broke ground on a new 400-acre solid rocket motor test site in Weld County, Colorado marking a significant expansion in the company’s ability to design, build, and test and qualify large solid rocket motor systems, to include those required for standard missile programs, in support of national and missile defense priorities.
“This facility represents a major step forward in our ability to deliver qualified SRMs that are scalable, flexible, and ready to meet the evolving threat environment,” said Dan Jablonsky, CEO of Ursa Major. “It’s a clear demonstration of our commitment and ability to rapidly advance and expand the American-made solid rocket motor industrial base that the country needs, ensuring warfighters will have the quality and quantity of SRMs needed to meet mission demands.”
The new site will serve as the test and qualification site for Ursa Major’s large-scale SRMs, supporting current and future missile systems, and accelerating the path to production. Designed for safe, full-scale static firings, and future qualification processes like drop and temperature storage testing, the site enables validation of SRMs built using the company’s Lynx manufacturing process, a software-driven, additive-enabled production system that supports multiple motor sizes, from 2-22″ diameters, and thrust profiles without retooling.
This groundbreaking comes on the heels of a high-paced year for Ursa Major’s SRM program. To date, Ursa Major has conducted four successful SRM flight tests and more than 450 static fires, demonstrating both scale and repeatability across multiple systems. Those included multiple firings of a 5″ diameter solid rocket motor validating Ursa Major’s proprietary manufacturing process, multiple 10″ diameter static fires of a highly loaded grain motor, and a series of static fires for a 2.75″ HLG SRM, extending range with the APKWS® laser-guided system.
Backed by U.S. Navy investment and an industrial base in urgent need of modernized SRM capability, Ursa Major is scaling production and growing physical test infrastructure to meet the moment and deliver capabilities faster and more affordably than legacy providers. Work on the site is already underway, and we will begin testing at the site in Q4 2025.
