X-Bow wins $11M grant to break Pentagon's rocket motor duopoly
What's the deal? X-Bow Systems, an Albuquerque-based defense manufacturer, has won a $10,981,581 grant from the Missile Defense AgencyDealroom has a profile for this one. Try Dealroom → to design, develop, and demonstrate a high-performance solid rocket motor. The award, made on July 2 under the agency's Rapid Response Small Launcher Technology program, follows earlier evaluation stages that proved the company's concept.
What's the endgame? The Missile Defense Agency stated the goal is expanding an industrial base that currently depends on what officials call a duopoly of two primary manufacturers. A solid rocket motor is the engine that propels a missile off the ground using pre-mixed solid propellant, making it reliable, storable for years, and quick to launch on demand.
Why now? For most of the past decade, only two companies — Northrop GrummanDealroom has a profile for this one. Try Dealroom → and L3Harris's Aerojet Rocketdyne division — could build these motors, a concentration traced to defense industry consolidation completed by 2015. That narrow supplier base became a national security concern as the Pentagon pushed into hypersonic weapons and next-generation missile defense.
Then-Under Secretary of Defense for Acquisition and Sustainment William LaPlante told Congress in 2023 that replenishing certain munitions stockpiles could take "five to ten years" at then-current production rates. The warning helped drive the Pentagon's push to qualify new suppliers.
What sets it apart? X-Bow uses a patented process it calls Additive Manufacturing of Solid Propellant (AMSP), applying 3D-printing techniques to build motors faster and cheaper than the decades-old casting methods the established manufacturers have relied on since the Cold War. In August 2024, the company completed a static test of the Ballesta-34, which it says is the largest advanced-manufactured solid propellant rocket motor ever fired.
That milestone placed X-Bow alongside Northrop Grumman and L3Harris as one of only three US companies now capable of producing strategic-class motors. The firm entered the effort in 2023 with a $64 million contract from the Department of Defense's manufacturing capability expansion office.
The signal: The grant ranks among the largest US security grants on record, in the 95th percentile of 708 comparable rounds. It reflects a broader Pentagon strategy to diversify a supply chain central to America's missile arsenal, betting that a new entrant can ease the production bottleneck that money alone cannot fix.
