Ursa Major Showcases Reusable Hypersonic Milestone and Supply-Chain Edge in Space Sector

Ursa Major advanced its position in the defense and space propulsion market this week, highlighted by a key operational milestone for its Hadley liquid rocket engine. The company reported 10 consecutive successful flights with Stratolaunch at sustained hypersonic speeds, including multiple missions using previously flown engines, underscoring reusability and durability.

CEO Chris Spagnoletti framed these as operational test-bed flights rather than demonstrations, pointing to a scalable hypersonic capability for national security users. Ursa Major now aims to ramp production and flight cadence, positioning itself as one of only three U.S. firms to prove and refly a reusable hypersonic liquid rocket engine.

In parallel, the company used recent LinkedIn posts to spotlight growing strain in the U.S. space supply chain, citing an Aerospace Industries Association and PwC report that flags component shortages, constrained test capacity, and a fragile supplier base. Ursa Major is presenting its domestic chemical propulsion supply chain as a solution focused on speed, scale, and reliability.

The company emphasized its manufacturing heritage, flight-proven engineering, and extensive test capabilities as building blocks for resilient propulsion delivery to government and commercial customers. It is also leaning into industry engagement, encouraging meetings at the Space Symposium as part of an active business development push.

These developments build on earlier disclosures of capacity expansion and vertical integration, including higher volume manufacturing, a large solid rocket motor test site, and an ISO-certified clean room for in-space systems. Collectively, the week’s news points to Ursa Major consolidating its role as a critical propulsion supplier in hypersonics and the broader U.S. space industrial base, with improving prospects tied to both performance milestones and structural supply-chain demand.
