Cape Canaveral Air Force Station, Fla., (March 25, 2015) – A United Launch Alliance (ULA) Delta IV rocket successfully launched the ninth Global Positioning System (GPS) IIF satellite for the U.S. Air Force at 2:36 p.m. EDT today from Space Launch Complex-37. This is ULA’s fourth launch in 2015 and the 95th successful launch since the company was formed in December 2006.

“Congratulations to the Air Force and all of our mission partners on today’s successful launch of GPS IIF-9! The ULA team is privileged to work with this world-class U.S. government and contractor mission team, and we are proud to contribute to the GPS capabilities that were delivered to orbit today,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs.“ This entire team is focused on 100 percent mission success, one launch at a time, and also providing on-time launches to meet our customer’s mission needs.” 

This mission was launched aboard a Delta IV Medium-plus (4,2) configuration Evolved Expendable Launch Vehicle (EELV) using a single ULA common booster core powered by an Aerojet Rocketdyne RS-68 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 four-meter-diameter composite payload fairing. 

GPS IIF-9 is the ninth in a series of next generation GPS satellites and will join the GPS worldwide timing and navigation system utilizing 24 satellites in six different planes, with a minimum of four satellites per plane positioned in orbit approximately 11,000 miles above the Earth’s surface. The GPS IIF series provides improved accuracy and enhanced performance for GPS users. 

ULA's next launch is the Atlas V AFSPC-5 mission for the United States Air Force, scheduled for May 6 from Space Launch Complex-41 from Cape Canaveral Air Force Station, Florida.

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 90 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.
