It was the first Delta IV HLV to be launched from the West Coast of the U.S., and it carried a national security payload for the National Reconnaissance Office.
"The teamwork between the 30th Space Wing, the National Reconnaissance Office, United Launch Alliance and numerous other agencies was outstanding for our first-ever Delta IV HLV from Vandenberg Air Force Base," said Col. Keith Balts, the 30th Space Wing vice commander and launch decision authority. "I'm very proud to be part of the team who worked so hard to make this mission a success."
