ULA Successfully Launches 4 Missions in Just 7 Weeks
A United Launch Alliance (ULA) Atlas V rocket carrying a payload for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-41 on May 22 at 9:09 a.m. EDT. Designated NROL-33, the mission is in support of national defense.
"Congratulations to all of our mission partners on today's successful launch of the NROL-33 mission! The ULA team is honored to deliver another critical national security asset to orbit together with the NRO Office of Space Launch and the Air Force," said Jim Sponnick, ULA vice president, Atlas and Delta Programs. "Today's launch occurred six days after last week's GPS IIF-6 launch – the second time this year that this team has launched back-to-back missions within a week. Successfully launching at this tempo is a testament to the team's focus on mission success, one-launch-at-a-time, and continuous improvement of our launch processes."

This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 401 configuration vehicle, which includes a 4-meter-diameter payload fairing. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine, and the Centaur upper stage was powered by a single Aerojet Rocketdyne RL10A engine.
ULA's next launch is the Delta II OCO-2 mission for NASA, scheduled for July 1 from Space Launch Complex-2 at Vandenberg Air Force Base, Calif.
The EELV program was established by the United States Air Force to provide assured access to space for Department of Defense and other government payloads. The commercially developed EELV program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.
With more than a century of combined heritage, United Launch Alliance is the nation's most experienced and reliable launch service provider. ULA has successfully delivered more than 80 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system. Reliable launch, real-world benefits.
