A United Launch Alliance (ULA) Delta IV rocket carrying the eighth installment of the Wideband Global SATCOM (WGS) satellite for the United States Air Force lifted off from Space Launch Complex-37 December 7 at 6:53 p.m. EDT. This is ULA’s 11th launch in 2016 and the 114th successful launch since the company was formed in December 2006.
«Thank you to the U.S. Air Force and industry team whose flawless execution enabled today’s successful launch of the WGS-8 mission», said Laura Maginnis, ULA vice president of Custom Services. «Last week ULA celebrated our anniversary and 10 years of 100% mission success. This evening’s launch epitomizes why our customers continue to entrust ULA to deliver our nation’s most crucial space capabilities».
This mission was launched aboard a Delta IV Medium+ (5, 4) configuration Evolved Expendable Launch Vehicle (EELV) powered by one common booster core and four solid rocket motors built by Orbital ATK. The common booster core was powered by an RS-68A liquid hydrogen/liquid oxygen engine producing 705,250 pounds of thrust at sea level. A single RL10B-2 liquid hydrogen/liquid oxygen engine powered the second stage. The booster and upper stage engines are both built by Aerojet Rocketdyne. ULA constructed the Delta IV Medium+ (5,4) launch vehicle in Decatur, Alabama.
WGS-8, the second Block II Follow-on satellite, supports communications links in the X-band and Ka-band spectra. The WGS-8 satellite will be able filter and downlink up to 8.088 GHz of bandwidth. WGS satellites are an important element of a new high-capacity satellite communications system providing enhanced communications capability to our troops in the field.
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.
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 110 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.
