It is the first spacecraft in the series in the Block II configuration that adds throughput support for airborne intelligence-surveillance-reconnaissance platforms requiring ultra-high bandwidth and data rates. This week has been a busy one for the WGS program, with the United States on Tuesday detailing a new partnership with five nations to enable the purchase of WGS-9, which the Air Force then ordered on the following day.
