Ursa Major's Solid Propulsion Ventures: 3D Printing and DoD Market Focus

Rocket engine startup Ursa Major plans to disrupt the solid rocket motors market by utilizing additive manufacturing techniques, commonly known as 3D printing. The company aims to address the broken supply chain and outdated processes in the industry, which have been exposed by the conflict in Ukraine. Ursa Major intends to develop motors ranging from 2 to 22.5 inches in diameter and has already tested a six-inch pathfinder prototype. The company has an undisclosed U.S. government customer and aims to supply motors to the Department of Defense while partnering with other manufacturers. Ursa Major is one of several startups attempting to enter the solid rocket motors business, challenging the dominance of incumbents like Northrop Grumman and Aerojet Rocketdyne.
