Nearly a year prior to a deadline for two competing teams to reach a critical design review phase in the development of a Next-Generation Interceptor for homeland defense, the Missile Defense Agency chose Lockheed Martin to move forward rather than carry both teams through the next phase of technology development.
Lockheed and its Aerojet Rocketdyne partner completed the preliminary design review at the end of September. A Northrop and RTX team passed through the same design review at the end of January.
