Orbital ATK said Friday the Boeing–Lockheed Martin joint venture’s Delta IV rocket that took off from Vandenberg Air Force Base in California as part of the NROL-47 national defense mission has two Orbital ATK-built Graphite Epoxy Motors 60 solid rocket motors that provided at least 560,000 pounds of thrust during the launch.
Orbital ATK will integrate GEM 63 solid boosters into ULA’s Atlas V and supply GEM 63L motors for new Vulcan rockets by 2019.
The company also provided seven composite structures for the rocket, a propellant tank for the upper stage and a nozzle for the vehicle’s RS-68A engine.
The Dulles, Virginia-based aerospace and defense contractor produced the boosters at its facilities in Utah and composite structures at its Iuka, Mississippi-based facilities.
The propellant tank and nozzle were respectively manufactured at the company’s facilities in California and Utah.
