WGS-9, which was purchased for the Air Force by a group of other nations in exchange for access to the WGS system, will join the eight satellites already in orbit which launched between 2007 and 2016. Built by Boeing, WGS satellites are based on the BSS-702 platform and designed for fourteen years of service. Each spacecraft is equipped with an Aerojet Rocketdyne R-4D-15 High Performance Apogee Thruster (HiPAT) to perform insertion into geosynchronous orbit and four Xenon-Ion Propulsion System (XIPS-25) thrusters for stationkeeping. The WGS-9 satellite carries X and Ka-band transponders. The satellite will use a phased array antenna to provide eight jam-resistant X-band beams, while ten individual antennae will provide Ka-band beams. An additional X-band payload will be used to provide Earth coverage. The satellite can support 8.088 gigahertz of bandwidth, with an expected downlink speed of up to 11 Gbps.
