Boeing X-45 Joint Unmanned Combat Air System
Initially managed by the Defense Advanced Research Projects Agency, the Pentagon’s Skunk Works, the X-45A technology demonstrator for the stealth-equipped swept-wing jet previewed the first unmanned aerial vehicle capable of strike missions. In 2003 the Air Force and Navy folded the X-45 and X-47 programs into the Joint Unmanned Combat Air System. First flight: 2002. Transferred by the Air Force in 2004; one of two built. The other is at the National Museum of the U.S. Air Force, outside Dayton, Ohio.
