8th Boeing 702-class Wideband Global Satcom payload for the US Dept. of Defense carried an improved 'channelizer' that increases the capacity of the satellite. The second stage was reportedly deorbited, and the extra propellant required to do this necessitated a lower apogee transfer orbit than for previous WGS missions. By Dec 25 WGS-8 had reached a 26728 x 44588 km x 0.2 deg orbit.

See WGS 9 (USA 275). Wideband Global Satcom 9 was to be added to the US DoD communications satellite constellation. This WGS was partly funded by allied countries, although it was still owned and operated by USAF. A United Launch Alliance Delta 4 sent the satellite aloft on Mar 19, first into a 185 x 6097 km x 27.6 deg parking orbit and then to a 430 x 44262 km x 27.0 deg supersynchronous transfer orbit. The Delta 377 second stage was deorbited over the Pacific near the Phillipines with reentry around 1230 UTC.
