X-45B UCAV Grey Model Airplane

The X-45 unmanned combat air vehicle (UCAV) is a concept demonstrator for a next generation of completely autonomous military aircraft, developed by Boeing. The X-45 features an extremely low-profile dorsal intake placed near the leading edge of the aircraft. The center fuselage is blended into a swept lambda wing, with a small exhaust outlet. It has no vertical control surfaces — split ailerons near each wingtip function as asymmetric air brakes, providing rudder control, much as in Northrop's flying wings. In addition, the larger and more capable than its predecessor, the X-45B incorporates low-observable technologies.
