Dynamic Space Power
Ursa Major provides a resilient, domestic propulsion supply chain designed for speed, scale, and reliability. Built upon our manufacturing heritage, flight-proven engineering rigor, and deep test capability, we deploy chemical propulsion systems for sustained operational tempo
IN-SPACE MOBILITY
Designed for mission flexibility from LEO to GEO and beyond, Ursa Major’s modular, hydrazine-based satellite propulsion system delivers tactically responsive, highly maneuverable control for dynamic operations in orbit.
With in-house development of critical components, including the propellant tanks, controllers, and thrusters, we minimize lead times through modernized manufacturing approaches. Whether maneuvering to avoid threats, reconstitution of assets, or extending satellite lifespan, Ursa Major’s in-space propulsion unlocks high-performance mobility tailored to mission needs.
Hydrazine Monopropellant Systems
Ursa Major’s modular, hydrazine-based space propulsion systems deliver responsive orbital maneuverability through a productized architecture built for speed and scale. Strategic vertical integration of propellant tanks, controllers, and thrusters reduces lead times by one-third compared with current industry standards. The result is mission-ready propulsion that combines performance, reliability, and scale.
