Orbital ATK successfully tests first motor case for Next Generation Launch vehicle
(7 November 2017 - Orbital ATK) Orbital ATK has successfully completed an important milestone in developing advanced solid rocket propulsion and other technologies to be used in a new generation of intermediate- and large-class space launch vehicles.
The company is in early production of development hardware for its Next Generation Launch (NGL) system, and on October 27 successfully completed the structural acceptance test on the first motor high-strength composite case for this program.
The applied structural loads during the test demonstrated over 110 percent of maximum expected motor operating pressure and 110 percent of operational/flight and pre-launch compressive/tensile line loads. This full-scale motor case segment will be cast with inert solid rocket propellant in early 2018 and shipped to the launch site for check-out of ground operations.

“NGL is one of Orbital ATK’s top growth initiatives,” said Scott Lehr, President of Orbital ATK’s Flight Systems Group. “This milestone clearly shows the progress being made by the hundreds of engineers and technicians in Utah and Arizona who are developing the NGL system.”
Orbital ATK’s NGL rocket family will be capable of launching the entire spectrum of national security payloads, as well as science and commercial satellites that are too large to be launched by the company’s current Pegasus®, Minotaur and AntaresTM space launch vehicles. The NGL vehicles will share common propulsion, structures and avionics systems with other company programs, including smaller space launch vehicles as well as missile defense interceptors, target vehicles and strategic missile systems.
“By sharing a skilled workforce, facilities and subsystems across multiple programs, we’ve designed NGL to be affordable and reliable,” said Lehr. “For example, NGL uses common avionics that have flown on more than 100 missions with 100 percent success.”
The next phase of the program is expected to begin when the Air Force awards the Launch Services Agreement in mid-2018, which would entail full vehicle and launch site development, with work taking place at company facilities in Promontory and Magna, Utah; Iuka, Mississippi; Chandler, Arizona; Kennedy Space Center, Florida; and Vandenberg Air Force Base, California.
