The system is controlled from the U.S. Air Force's 4th Space Operations Squadron at Schriever Air Force Base in Colorado, the added, and"delivers reliable and secure communications services worldwide 24 hours a day, seven days a week as a vital military asset to the U.S. and Allied forces."

The first WGS satellite launched in 2007. WGS-9, the most recent satellite to join the network, launched in 2017. The satellites have an estimated cost of about $340 million each, according to Via Satellite.

"WGS-10's launch is another giant step for military communications," said Steven Hayden, the U.S. government's WGS program manager. "I am very proud to be a member of this team, and I’m looking forward to a successful launch."

ULA initially planned to launch today's mission on Wednesday (March 13), but postponed the flight two days to allow extra checks on the Delta IV medium launch vehicle.
