Lockheed Martin says NGI Stage 2 rocket motor clears static-fire test in high-vacuum chamber

Lockheed Martin says it completed a successful static-fire test of the NGI program’s Stage 2 rocket motor in a high-vacuum chamber simulating low-Earth orbit.

• Test data met key performance metrics, including thrust, chamber pressure, combustion stability, thermal tolerance, and pressure tolerance.
• The milestone supports the program’s path to Critical Design Review, with fielding targeted by 2030.
• Results are expected to inform the final interceptor design and accelerate integration with the Ground-Based Midcourse Defense architecture.
• Lockheed is investing millions in new or expanded Alabama manufacturing capacity to support NGI production demand.
