The new funding will be utilized to meet growing demands in the U.S. industrial base for modern approaches that outperform legacy providers. The investment will accelerate the fielding of Ursa Major’s throttleable liquid-fueled hypersonic and space defense technology, as well as rapidly scale manufacturing for solid rocket motors and sustained space mobility systems.
