April 23/19: 11th WGS Communication Space Vehicle Boeing won a $605 million modification for the production of the Air Force’s 11th Wideband Global Satellite (WGS) Communication Space Vehicle. The DoD uses the WGS system to communicate with warfighters across the globe. Ten Ka-band and 8 X-band beam can be positioned anywhere in the field of view of each satellite. WGS combines unique commercial spacecraft capabilities that Boeing has developed, including phased array antennas and digital signal processing technology, into a powerful, flexible architecture. United Launch Alliance ULA is scheduled to launch the 11th satellite aboard a Delta IV rocket in November 2023. Since 2001, Boeing has been the prime contractor of the WGS, which was first launched in 2008. GS 4, which was launched off in 2012, was the first Block II series. WGS-10 was meant to be the last of the constellation. But in March 2018, Congress added $600 million for the procurement of WGS-11 and WGS-12. Boeing will perform work under the modification in El Segundo, California and expects completion by November 20, 2023.
