PROMONTORY, Utah (News4Utah) – Northrop Grumman Corporation conducted its first ground test of a 63-inch diameter Graphite Epoxy Motor (GEM 63) Thursday in Promontory.
Using advanced technology, the company developed this new rocket motor for use on the United Launch Alliance (ULA) Atlas V launch vehicle.
Northrop Grumman began developing the motor three years ago.
“As ULA’s largest legacy supplier of solid propulsion, we’re pleased that our most recent product has reached this important milestone. The successful completion of this test enables full production to begin,” said Scott Lehr, president, flight systems, Northrop Grumman.
The GEM 63 motor will replace previous strap-on boosters on ULA’s Atlas V rocket beginning in July 2019 with the Space Test Program (STP)-3 mission that will use five boosters.
