To meet the warfighter's demand of scaling existing systems and developing next generation capabilities, the industrial base needs to expand with innovative manufacturing methods that re-establish the U.S.’s leadership in space, hypersonic, and defense.

Propulsion is fundamental to our National Security

Storable, liquid rocket engines with the maneuverability and flexibility needed to match increasingly erratic hypersonic threats.

hypersonics mission

Hypersonics

Mixed product manufacturing approach to families of solid rocket motors for flexible, adaptable, and surge-capable production.

tactical systems

Launch and satellite propulsion systems that enable rapid mobility, resilient space operations, and on-orbit defense, engineered to move fast, maneuver freely, and respond quicker.
