March 17, 2019 – A United Launch Alliance (ULA) Delta IV rocket carrying the tenth Wideband Global SATCOM (WGS) satellite for the U.S. Air Force lifted off from Space Launch Complex-37 on March 15 at 6:26 p.m. MDT. ULA has been the exclusive launch provider for all ten WGS satellites.
“We are very proud to deliver this critical asset to orbit in support of the U.S. and Allied warfighters deployed around the world defending our national security,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “Thank you to the entire ULA team and mission partners for their outstanding teamwork and dedication to mission success.”
The WGS-10 satellite, built by the Boeing Company, is an important element of the new high-capacity satellite communications system. Each WGS satellite provides more wideband communications capacity than the entire Defense Satellite Communications System.
This mission launched aboard a Delta IV Medium+ (5,4) configuration vehicle, built in Decatur, Alabama, including a 5-meter Payload Fairing and standing at 218 feet. The common booster core for Delta IV was powered by the RS-68A engine, and the Delta Cryogenic Second Stage was powered by the RL10B-2 engine, both supplied by Aerojet Rocketdyne. Northrop Grumman provided the four solid rocket motors. At liftoff, the main engine and four solid rocket motors comined to produce approximately 1.7 million pounds of thrust.
To date ULA has a track record of 100 percent mission success with 133 successful launches.
