X-Bow Systems has secured a $10.9 million contract from the US Missile Defense Agency (MDA) to develop and conduct flight tests of a Low-Cost Interceptor intended to counter ballistic missiles, cruise missiles, and hypersonic threats at a significantly lower cost.
A key element of X-Bow’s approach is the in-house production of both the interceptor and its solid rocket motor (SRM). By reducing reliance on external motor suppliers, the company aims to cut costs, streamline production, and avoid supply chain constraints.
The award falls under the MDA’s Rapid Response Small Launcher Technology (R2SLT) initiative. Under the contract, X-Bow will design, develop, and demonstrate a high-performance SRM, with work scheduled to continue through July 2028.
The effort contributes to the MDA’s Low-Cost Interceptor program, which is targeting a maximum interceptor price of approximately $750,000. This is substantially lower than the roughly $4 million cost associated with Patriot PAC-3 interceptors.
Vertical Integration for Lower Costs
X-Bow is leveraging vertical integration to support its low-cost interceptor strategy. The company can develop and manufacture the airframe, solid rocket motor, and propellant within its own production ecosystem.
Its additive-manufactured solid-propellant technology is expected to accelerate development and production, enabling SRMs to move from design to manufacturing in days rather than the months or years typically required through conventional processes.
In addition, X-Bow recently revealed a separate interceptor designed to counter Group 3 unmanned aerial systems, including high-speed and supersonic drones, with a production cost of under $100,000 per unit.
Strengthening the Solid Rocket Motor Industrial Base
The new contract also supports wider US efforts to expand the domestic SRM manufacturing base. The Department of Defense has raised concerns over the industry’s dependence on only a limited number of major producers.
For decades, Northrop Grumman and L3Harris’ Aerojet Rocketdyne have been among the primary suppliers of solid rocket motors for US missile and interceptor programs. By supporting companies such as X-Bow, the Pentagon aims to introduce additional production capacity, strengthen supply chain resilience, and increase competition in the US missile propulsion sector.
