Northrop Grumman is about to complete construction of the next-generation Global Hawk unmanned aerial vehicle. The company said it received the last of two critical airframe components—a graphite-composite wing assembly and the first set of its vertical tails—keeping the program on track for flight test in Fall 2006. The new Global Hawk RQ-4B will have 50 percent more payload capacity than the current model, meaning it can carry more intelligence sensors. The fuselage is stronger, four feet longer, and slightly taller than the A model. The wingspan increased by some 15 feet, giving the B more fuel capacity, as well.
As Air Force leaders consider concepts of operations for Collaborative Combat Aircraft, sustainment in the field—and easing that support by using standard parts and limiting variants—should be a key consideration, according to a new study from AFA's Mitchell Institute of Aerospace Studies.
