IUKA — Alliant Techsystems composite and propulsion technologies recently supported a successful launch of a United Launch Alliance Delta IV rocket carrying a National Reconnaissance Office (NRO) payload.
The mission is in support of national defense.
ATK supplied 16 key composite structures for the launch vehicle. The components were produced using advanced hand lay-up, machining, and inspection techniques at ATK’s production facility in Iuka and Clearfield, Utah.
ATK designed and produced the nozzle for the Pratt & Whitney Rocketdyne-built RS-68 engine as well as the nozzle’s thermal protection material. The Delta IV’s RS-68 is the largest hydrogen-fueled engine in the world, utilizing an ATK nozzle that is the first of its kind in a liquid booster engine.
