United Launch Alliance successfully launches NROL-45 payload for the National Reconnaissance Office
A United Launch Alliance (ULA) Delta IV rocket carrying a payload for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-6, Vandenberg Air Force Base, on February 10 at 3:40 a.m. PST. Designated NROL-45, the mission is in support of national defense. This is ULA’s second launch in 2016 and the 105th successful launch since the company was formed in December 2006.
“Congratulations to the ULA team and our U.S. Air Force and NRO partners on the launch of NROL-45,” said Laura Maginnis, ULA vice president of Custom Services. “This is our second successful launch within five days for our U.S. government customer, a testament to our outstanding teamwork and focus on 100 percent mission success, one launch at a time. ULA is proud to be entrusted with safely and reliably delivering our nation’s most critical space assets to orbit.”
This mission was launched aboard a Delta IV Medium+ (5,2) configuration Evolved Expendable Launch Vehicle (EELV) using a single ULA common booster core powered by an Aerojet Rocketdyne RS-68A main engine along with two Orbital ATK GEM-60 solid rocket motors. The upper stage was powered by an Aerojet Rocketdyne RL10B-2 engine with the satellite encapsulated in a 5-meter-diameter composite payload fairing.
ULA’s next launch is the Atlas V OA-6 Cygnus International Space Station resupply mission, flown for Orbital ATK under NASA’s Commercial Resupply Services contract. The launch is targeted for March 22 from Space Launch Complex-41 from Cape Canaveral Air Force Station, Florida.
The EELV program was established by the U.S. 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.
