According to a CNN report the Boeing X-45 Unmanned Combat Air Vehicle (UCAV) has just completed its first test flight successfully. Unlike the now common Predator UAVs, the X-45 is designed as an autonomous stealth combat vehicle intended for first strikes. A better photo of the X-45 is available from the NASA Dryden Image Collection. More info and some cool artwork of early design proposals can be found on the FAS X-45 page.
