The launch of United Launch Alliance‘s Delta IV rocket with the Air Force’s third Wideband Global SATCOM satellite has been postponed until this morning due to inclement weather.
WGS 3 is the final Block I satellite of the constellation and will serve U.S. forces in Europe and Africa. WGS 1 is on orbit serving U.S. Pacific Command, while WGS 2 serves Central Command.
Air Force officials said last week that WGS 1 is providing Global Broadcast System services, comparable to DIRECTV, to soldiers in Iraq and Afghanistan. The system is used, for example, to send video from Predator and Reaper unmanned aerial vehicles feeds.
