USAF Concept
Jan 19, 2012 By Michael Mecham - aerospace daily and defense report
An agreement by Canada, Denmark, the Netherlands, Luxembourg and New Zealand to become subscribers to the Wideband Global Satcom (WGS) broadband communications network has prompted the U.S. Air
Force to exercise an option for Boeing to build a ninth spacecraft.
With their $377 million contract, the five nations join Australia, which funded WGS-6 in 2008, as members of the Air Force WGS team.
WGS-9 is the third spacecraft in a follow-on contract series that relies on Block II technology. Block II is distinguished by its switchable radio-frequency bypass system, which enables
transmission of airborne intelligence, surveillance and reconnaissance imagery data at three times Block I rates. All of the spacecraft are derived from Boeing’s commercial 702 satellite bus.
Boeing was informed in December to proceed with WGS-8; the WGS-9 authorization means the company will have five Wideband Global Satcoms under construction at its El Segundo, Calif., factory.
The eighth and ninth spacecraft have a combined value of $673 million and are part of a $1.09 billion contract modification the Air Force announced last September.
Meanwhile, preparations continue at Cape Canaveral AFS, Fla., for the launch of WGS-4, the first in the Block II series, on Thursday evening on a United Launch Alliance Delta IV. The launch
window opens at 7:38 p.m. EST.
