Posted: Wednesday, March 1, 2017

Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, supported today's successful launch of a United Launch Alliance (ULA) Atlas V rocket from Vandenberg Air Force Base, California. The rocket launched a classified satellite, designated NROL-79, for the U.S. National Reconnaissance Office (NRO) in support of a national security mission. Orbital ATK provided advanced hardware from across multiple divisions to the ULA Atlas V launch vehicle.



“Seeing another successful Atlas V launch bolsters the pride we have in our partnership with ULA and confirms the trust they and the NRO place in us in delivering this critical asset for our nation’s security,” said Steve Earl, Vice President and General Manager of Orbital ATK’s Aerospace Structures Division. “Our highly engineered composite structures and control products, unwavering commitment and exceptional teamwork ensure dependable access to space and affordable innovation for our customers.”



Orbital ATK produced the 10-foot diameter composite heat shield, which provides essential protection for the first stage of the launch vehicle. The assembly was fabricated using advanced fiber placement manufacturing techniques at the company’s Iuka, Mississippi, facility. This is the 70th Atlas V launch using Orbital ATK-built composite structures.



This flight also marked the 35th consecutive successful flight of the Orbital ATK retro motors. Eight of these solid motors supported separation of the spent first stage. The Atlas V retrorocket is built by Orbital ATK’s Defense Systems Group at its facility in Elkton, Maryland. Orbital ATK manufactured the Reaction Control System propellant tank for the ULA Atlas V at its Commerce, California, facility.
