Ursa Major’s $100M Raise Signals a New Phase in U.S. Hypersonics and Propulsion Manufacturing

We get excited when a propulsion company moves from prototype to production, but as a Colorado-based publication we’re especially excited when it happens in our own state. That’s exactly what’s happening with Ursa Major. The Colorado-based propulsion manufacturer has secured a $100 million Series E financing round, paired with an additional $50 million in debt commitments. More importantly, the company enters 2025 with over $115 million in booked business across defense and commercial contracts, an unmistakable indicator that demand for advanced propulsion has shifted from exploratory to operational.

For aerospace executives managing programs in hypersonics, responsive launch, or in-space mobility, Ursa Major’s scale-up represents a defining moment. The bottleneck is no longer innovation. It’s throughput. And Ursa Major is positioning itself as one of the few U.S. players capable of building propulsion systems fast enough, and at low enough cost, to meet emerging mission needs.

The company’s strategy is built around highly modular propulsion lines that can be reconfigured to meet both hypersonic and solid rocket motor requirements. This is especially relevant for defense programs that need validated, manufacturable propulsion quickly. Additive manufacturing sits at the core of this model. While many engine companies tout AM capabilities, Ursa Major is now attempting to industrialize them: scaling print capacity, optimizing post-processing workflow, and integrating automated inspection into every step of the process.

The capital infusion will accelerate that transition from prototype to production-scale repeatability. For operators, that means shorter lead times, greater supply chain resilience, and a realistic path to sourcing propulsion domestically at meaningful volumes.

But operationalizing AM at this scale brings risk. Process control must be razor-tight; qualification of printed components must evolve beyond engineering experiments into statistically rigorous manufacturing standards. And the supply chain, from specialty alloys to propellants, must scale alongside engine production.

Yet the direction is clear: Ursa Major is becoming a true production supplier. For aerospace primes, it’s time to evaluate them on the same criteria used for long-term propulsion incumbents: quality assurance maturity, integration support, data transparency, and lifecycle cost. For program managers, the opportunity lies in incorporating modular engines early into development, where the cost and schedule benefits multiply.

In a market where propulsion is increasingly the pacing item for hypersonics, cislunar operations, and tactical launch, Ursa Major’s expansion could reset expectations for domestic propulsion availability. Executives who understand that shift, and plan for it, will be better positioned than those waiting for the old supply base to catch up.
