Delta IV WGS-9 Mission ArtworkRocket/Payload: A United Launch Alliance Delta IV Medium+ (5,4) rocket will launch the ninth Wideband Global SATCOM (WGS-9) mission for the U.S. Air Force.
Date/Site/Launch Time: Wednesday, March 8, 2017, from Space Launch Complex (SLC)-37 at Cape Canaveral Air Force Station, Florida. The 121-minute launch window opens at 6:35 p.m. EST.
Live Broadcast: Tune in to ULA’s live launch day broadcast beginning at 6:15 p.m. EST.
Mission Description: WGS satellites are important elements of a new high-capacity satellite communications system providing enhanced communications capabilities to our troops in the field. WGS has 19 independent coverage areas, 18 of which can be positioned throughout its field-of-view. This includes eight steerable/shapeable X-band beams formed by separate transmit/receive phased arrays; 10 Ka-band beams served by independently steerable diplexed antennas; and one transmit/receive X-band Earth-coverage beam. WGS can tailor coverage areas and connect X-band and Ka-band users anywhere within its field-of-view. The X-band phased array antenna enables anti-jam functionality without sacrificing performance.
Launch Notes: WGS-9 will mark the seventh flight of the Delta IV in the Medium + (5,4)configuration; all launches in this configuration have delivered WGS missions to orbit. This mission also will be the 35th launch of the Delta IV since its inaugural launch in 2002.
