Northrop Grumman Corporation has completed the first full-scale mix of the solid rocket motor propellant for its Next Generation Interceptor (NGI). This successful full mix helps ensure the solid rocket motors supporting the Northrop Grumman and Raytheon Technologies’ NGI solution are on track to complete qualification via static test.

The successful operation was completed using the company’s remote automated solid rocket motor manufacturing facilities in Bacchus, Utah. The unique, automated, 1,800-gallon mixers, combined with the company’s proven automation capabilities, enables consistent and safe production of high performing solid rocket motors for government and commercial customers, including the Missile Defense Agency.
