The reason I am qualifying the success of the launch at this moment is that, because of the national security nature of the payload, they will only release details about the success of the final orbital maneuvers long after they have been completed. Right now these details are blacked out. Update: the launch was successful.
ULA has another launch of an NRO satellite scheduled for October, a date not yet determined. Right now, the U.S. has had 20 launches in 2017, far more than any other nation, with SpaceX’s 13 launches comprising the bulk.
