Boeing has begun building the latest version of the Wideband Global SATCOM satellite system, WGS-11+, using advanced techniques to integrate the latest commercial technology while enabling a high-paced five-year schedule that will reportedly deliver years faster than similar clean-sheet designs.
"We're moving at record-breaking speed to deliver the unmatched resilience, efficiency, and throughput WGS-11+ offers our warfighters," Col. Matt Spencer, Space Systems Command Geosynchronous Earth Orbit and Polar Division Senior Materiel Leader, said. "Boeing's ability to rapidly integrate the latest commercial technology into our infrastructure gives us a competitive edge on the battlefield."
Boeing and the US Space Force completed the system's critical design review in late 2021, officially launching the program's production phase. Boeing is leveraging additive manufacturing, rapid prototyping, agile development and other advanced techniques to create cost and schedule benefits, while boosting system performance.
"We're printing more than a thousand parts for WGS-11+, giving us the capability to introduce customisation in a way that improves system performance, without requiring extensive integration times or customised tooling," Troy Dawson, Boeing Government Satellite Systems vice president, said. "We understand how important speed is to the mission. That production speed translates to effectiveness against threats. As we continue to invest our technology and processes, we know that a similarly capable satellite could be delivered even faster."
Boeing says that WGS-11+ showcases 'an evolution in phased array technology'. Based on Boeing's advances on its commercial 702X software-defined satellite payload, it is capable of generating hundreds of electronically-steered beams simultaneously, reportedly providing users with more than twice the mission capability compared to satellites within the existing WGS fleet.
Like 702X, each individual beam is shapeable and can be uniquely tailored to any operation, expecting to enable increased mission flexibility and responsiveness. Narrower beam widths with dual polarisation unique to WGS-11+ help protect against jamming and interference while allowing greater frequency reuse.
When it joins the constellation of ten WGS satellites, WGS-11+ will increase throughput capacity of essential communication services for the US government and its allies. It is scheduled for delivery in 2024.
