WGS is the DoD's highest-capacity satellite communications system. Each WGS satellite can route 2.1 to 3.6 Gbps of data -- providing more than 10 times the communications capacity of the predecessor DSCS III satellite. Using reconfigurable antennas and a digital channelizer, WGS also offers added flexibility to tailor coverage areas and to connect X-band and Ka-band users anywhere within the satellite field of view. The system provides tremendous operational flexibility and delivers the needed capacity, coverage, connectivity and control in support of demanding operational scenarios. The first Wideband Global SATCOM satellite was launched Oct. 7, 2007 aboard an Atlas V launch vehicle. The fourth satellite, the first in the Block II spacecraft, was launched on Jan. 19, 2012, aboard a Delta IV launch vehicle. All four operational satellites are meeting or exceeding their mission requirements.
