Lockheed Martin's Next Generation Interceptor program cleared a key milestone with a successful static fire test of its Stage two motor. The test, conducted in a high-vacuum chamber simulating low-Earth orbit conditions, validated the L3Harris Technologies-built motor's ability to handle extreme thermal and pressure stresses. The company says the test confirmed critical performance metrics including thrust, chamber pressure and combustion stability. Christopher Jewell, Lockheed Martin NGI vice president, said the results build confidence the interceptor will meet demands for fielding by 2030. Data from the test will inform final design work.
