Smithsonian Air and Space Museum / The X 45 is a robotic combat aircraft developed by Boeing which first flew in May, 2002. Designed to carry 3,000 pounds of guided bombs, the Richard Erwin                                           plane has a range of about 375 miles at a speed of about 570 mph and is controlled by a pilot on the ground. A later version of the aircraft had a 8/10/2009                                                  much greater range but the original project has now been cancelled. However, it seems that a new robotic combat aircraft is now being developed                                                                    using much of the X 45's test data.
