United Launch Alliance will launch a Delta IV rocket carrying the WGS-9 satellite for the United States Air Force.
The Delta IV will fly in the medium+ configuration with a single common core booster, four strap-on solid rocket boosters, and a 5 meter payload fairing.
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.
