NG Graphite Epoxy Motor 63 test ( GEM 63 QM 2)

Northrop Grumman Corporation conducted the second qualification test (QM2) of its 63inch diameter Graphite Epoxy Motor (GEM 63) in Promontory, Utah, on 4 April 2019. The test was designed to validate the ballistic performance of the motor, such as pressure and thrust. The GEM 63 motor will be used as a direct replacement of the previous strapon boosters on ULAs Atlas V rocket beginning in July 2019 with the Space Test Program (STP)3 mission that will use five boosters.
