"GPS III is the most powerful and complex GPS satellite ever designed and built, and it's now into a smooth production flow. The real credit goes to the Air Force for all the Back to Basics work done in advance, reducing program risk for all the GPS III satellites going forward. We are looking forward to bringing GPS III's advanced capabilities to our warfighters in 2018."
