In August 2021, nuo pattern company reached strategy of “ Liu Ji to deter ” (GBSD) one of the project important production milestone, the production of a shield of engine heat insulation that finished class solid rocket works. The extreme temperature that because in-house engine combustion arises,the shield of class heat insulation of this cylinder shape can isolate, used composite material design. Gesso of the preexistence when making machines adiabatic layer on core strong pattern, reuse twines a law to make composite material case in the side outside insulation layer. Class rocket motor is about to undertake the test of tool and workmanship is evaluated now, include pressure test to wait. Nuo pattern company already began to undertake production to engine of the 2nd class at present, used similar technology likewise. Steve Lunny of vice president of project of GBSD of Nuo pattern company expresses, this one production milepost proved Nuo pattern company is in design of motor of class solid rocket, workmanship, tool and business system have taller maturity. In September 2020, nuo pattern company wins GBSD project and production development contract, begin system of ballistic to American Liu Jizhou border missile to undertake modernization is transformed, produce the missile of new-style GBSD intercontinental that has motor of rocket of 3 class solid for the U.S. Army.
