Propulsion to, in,
and beyond orbit
From liftoff to low Earth orbit, Ursa Major’s satellite propulsion, space-based defense, and launch systems move faster, fly farther, and adapt to the evolving threat landscape–delivering resilient space operations and true freedom to maneuver.

In-Space Mobility
Ursa Major’s modular, hydrazine-based satellite propulsion system delivers tactically responsive, highly maneuverable control for dynamic operations in orbit. Designed for mission flexibility from LEO to GEO and beyond, our monopropellant system is highly maneuverable and optimized for custom burn durations in the vacuum of space.
With in-house development of critical components, including the propellant tanks, avionics, and thrusters, we minimize lead times through ensuring a resilient, scalable supply chain and productized components. Whether maneuvering to avoid threats, repositioning for rapid response, or extending satellite lifespan, Ursa Major’s in-space propulsion unlocks high-performance mobility tailored to mission needs.

Space-Based Defense
The Draper liquid rocket engine is designed for tactical hypersonic applications, missile defense missions, and in-space rapid maneuverability. This storable propulsion system offers the same launch readiness and storability as a solid rocket motor, with the added benefits of restart capability, unique mobility and range, as well as active throttle control with the flexibility to support new mission profiles.
With tactical storability and cost-effective manufacturing, solid rocket motors developed via LYNX, Ursa Major’s Mixed Model Manufacturing approach, are ideal for space-based defense systems. This production infrastructure supports SRM manufacturing through product-agnostic tooling systems across a range of diameter classes, enabling versatile responsiveness to defense needs and a streamlined path to qualification.
