The satellite was deployed on the 7th orbit and then ignited its IUS rocket at the ascending node of the 8th orbit, to place it in a geo-synchronous transfer orbit. The classified payload was deployed successfully and boosted into its operating orbit by an Inertial Upper Stage (IUS) booster according to an Air Force announcement.
