Solutions for Defense

Propulsion for today's critical national security needs and tomorrow's emerging threats

The Problem

National security depends on access to propulsion.

But propulsion is a bottleneck. The U.S. supply of rocket engines and solid rocket motors is constrained, while allied nations are asking for more. To meet demand, the industrial base needs to expand with innovative manufacturing methods that re-establish the U.S.’s leadership in space, hypersonic, and defense.

The Approach

Hardware in the hands of the warfighter—faster

Leveraging additive manufacturing to mass produce hypersonics defense systems and tactical munitions, Ursa Major puts hardware in the hands of the warfighter—faster.

Production at scale
One 3D printer can build thousands of motors for small, portable missile systems, while maintaining modularity.
Speed and flexibility
Additive manufacturing methods reduce manufacturing cycles and unlock higher performance. We complete in days what used to take months to produce.
Lower costs
Motors for portable tactical missiles at half the cost of existing programs of record.
Surge readiness
Quicker path to production with uniform, flexible production cells that can quickly scale with demand.
