KEVIN FLYNN PHOTO BOEING FRONTIERS September 2007 13 n COVER STORY The B-2—called “the stealth bomber” because of its ability to elude enemy radar—was built by an industry team featuring Northrop Grumman, Boeing and Vought Aircraft Industries. Boeing built primary structural components for the B-2 including outboard and aft-center sections of the bomber’s fuselage, and supplied the bomber’s fuel systems, weapons delivery system PHOTO and landing gear. Boeing remains responsible for one-third of the aircraft’s systems and structural elements. BOEING Weaponry.
