To date ULA has launched 153 times with 100 percent mission success.

"The NRO has been, and continues to be, a phenomenal partner through 32 collaborative launch campaigns, stemming from ULA's very first launch in 2006," said Gary Wentz, ULA vice president of Government and Commercial Programs.

"This mission was ULA's 96th National Security mission and the NRO's 10th mission on board a Delta IV Heavy launch vehicle – a history that we are very proud of."

"This was also ULA's 95th Delta mission from Vandenberg Space Force Base and our fifth and final Delta IV Heavy from the West Coast, completing a long, successful tenure of delivering critical national security payloads," added Wentz. "We look forward to preparing Space Launch Complex-3 for future Vulcan flights from the West Coast."

ULA's next launch is a commercial launch of the SES-20 and SES-21 mission, planned for Sept. 30 from Cape Canaveral Space Force Station, Florida.
