Ursa Major Technologies

Ursa Major Technologies Inc. is an American aerospace and defense propulsion manufacturer founded in 2015 by Joe Laurienti, a former SpaceX and Blue Origin propulsion engineer, and headquartered at 19750 Co Rd 7 in Berthoud, Colorado, with additive manufacturing operations in Youngstown, Ohio. The company designs, builds and hot-fire tests liquid rocket engines, solid rocket motors and in-space propulsion systems for space launch, hypersonics and U.S. and allied defense customers. Its product line includes the 5,000 lbf Hadley oxygen-rich staged-combustion liquid engine — the first Ursa Major engine to reach flight qualification for hypersonic missions — and Draper, a storable, throttleable, restartable engine for tactical hypersonic strike, missile defense and rapid in-space maneuver, alongside a solid rocket motor line validated through static fire and a chemical propulsion capability for tactical satellite bus systems. Ursa Major was the first American company to successfully fire an oxygen-rich staged combustion engine; it states it has delivered more than 100 engines and logged over 100,000 seconds of hotfire testing, with engines and motors more than 80 percent 3D printed by mass. The company is AS9100D, ISO 9001 and CMMC Level 2 certified. Ursa Major is a hardware manufacturer selling to government and prime-contractor customers: it publishes no public developer API, SDK, CLI, developer portal or machine-readable API contract of any kind.

    so there is nothing to expose as an API — ursamajor.com is a WordPress marketing site whose only machine-readable output
    is a Yoast-generated llms.txt with empty link targets, and no api., developer., docs. or portal. subdomain resolves at
    all.
