Lockheed Martin says Next Generation Interceptor second-stage motor passes static-fire test

Lockheed Martin said a Stage 2 rocket motor for its Next Generation Interceptor program has completed a static fire inside a high-vacuum chamber designed to replicate low-Earth orbit, marking a key step toward its intended missile defense mission.

Built by L3Harris Technologies, the motor was tested to verify it can endure the extreme thermal and pressure stresses expected during interceptor operations. The run confirmed performance metrics including thrust, chamber pressure and combustion stability, the companies said.

Christopher Jewell, Lockheed Martin NGI vice president, said: “This successful static fire test is a significant milestone on the path to the Critical Design Review and confirms our confidence that the NGI motor will meet the demanding performance envelope required for fielding by 2030. The data gathered will directly inform the final interceptor design and accelerate integration with the Ground-Based Midcourse Defense architecture.”

Program leaders pointed to several factors underpinning schedule momentum: the use of digital engineering to shorten design and validation cycles; capital spending to build or expand manufacturing facilities in Alabama with advanced production lines and tooling; and a broad national supply chain supporting delivery.

NGI is intended to enable a more capable Ground-Based Midcourse Defense architecture and serve as a core element of a next-generation missile defense solution, with the interceptor described as significantly increasing the nation’s firepower against the most destructive ballistic missile threats.
