Ursa Major was founded to address a critical shortfall in the U.S. industrial base and bring a new model to aerospace and defense systems: we design and manufacture the world’s leading propulsion systems for space, hypersonic applications, and missile systems. 

Our products and technologies require an extraordinary team – a team that will mold tomorrow’s technologies while deploying today’s best. We are an intrinsically motivated team that has a passion for solving problems and empowering each other every day to develop our skills, knowing that there is always room for growth.

As Ursa Major expands into the realm of solid propulsion, we’re assembling the most innovative and nimble team in order to unseat the reigning players.  We’re applying the latest technologies to an outdated business model that improves cost, lead time, and flexibility without impacting reliability.  We must continue to build in-house capabilities in energetics, ballistics, and composites with an emphasis on novel designs focused on manufacturability and high-rate scalability.
