The Ascent of the Robotic Attack Jet

Compared to many aeronautical curiosities that have taken wing at NASA's Dryden Flight Research Center at California's Edwards Air Force Base over the years, the latest military test stunts did not appear very remarkable. Last April, a low-slung aircraft, about the size of a sport utility vehicle but with batlike wings similar to those of the B-2 stealth bomber, took off, flew at 10,500 meters and then dropped a 110-kilogram inert precision bomb while zipping along at 700 kilometers per hour. Four months later, a pair of the aircraft took off and flew together. These were modest stunts, to be sure, except for this fact: the jets have no pilots. They are the future of warfare, the first working models of networked autonomous attack jets, and the U.S. Department of Defense would like to start building them by 2010.
