Pentagon Funds X-Bow Interceptor Targeting $750,000 Cost

The Pentagon has awarded X-Bow Systems almost $11 million to develop a lower-cost interceptor under the Missile Defense Agency’s Low-Cost Interceptor program.

The project is also part of the Rapid Response Small Launcher Technology program and aims to produce a weapon costing below $750,000 per launch—roughly one-fifth the cost of a Patriot missile. X-Bow will use the funding for propulsion work and to prepare a prototype for a planned flight demonstration.

The agreement requires the company to deliver a prototype system by late 2027. That milestone will not represent a fully operational weapon. Testing and evaluation will still be needed before deployment.

X-Bow produces its solid rocket motors and propellant internally, giving it control over more of its manufacturing process. The company is examining ways to reduce costs across interceptor components.

The Pentagon faces pressure to expand production as existing systems remain expensive and slow to manufacture. Patriot replacement rounds cost around $3.9 million each, while production depends on a small number of established suppliers. The Department of Defense said the contract addresses the need to expand the solid rocket motor industrial base, which currently relies on two primary manufacturers.

The project remains at an early development stage. Officials must determine whether the system can meet operational standards at a lower cost.
