Overview
- Lockheed Martin reported that L3Harris conducted a static hot‑fire of the Next Generation Interceptor Stage 2 solid rocket motor inside a high‑vacuum chamber that simulates low‑Earth‑orbit conditions.
- Engine measurements from the test confirmed key performance metrics, including sustained thrust, chamber pressure and combustion stability under the extreme thermal and pressure stresses expected in flight.
- Lockheed says the test data will directly inform the final interceptor design and move the program toward its Critical Design Review as teams begin integration planning with the Ground‑Based Midcourse Defense architecture.
- The company is investing millions to build or expand purpose‑built manufacturing capacity in Alabama to support industrial scale‑up and meet the program’s targeted 2030 fielding objective.
- NGI is designed to boost U.S. midcourse missile defense capacity by replacing current interceptors, and the vacuum static‑fire tests are a standard qualification step used to validate motor performance before final design and production.
