US Next Generation Interceptor Is 18 Months Late and Has Yet to Fly

Lockheed Martin's Next Generation Interceptor remains about 18 months behind schedule, with fielding targeted for 2030 and the date of its first flight test not yet made public. The Missile Defense Agency identified problems involving the solid rocket motor, inertial measurement unit and onboard sensors as development approached manufacturing. NGI is intended to strengthen the Ground-based Midcourse Defense system by intercepting incoming intercontinental ballistic missile threats outside the atmosphere. A critical design review is planned for late 2026, and Lockheed has opened an assembly facility in Courtland, Alabama, but completed ground tests have yet to demonstrate the interceptor's performance in flight.
