The Stealth Effect
It's sleek. And simple. And unmanned, of course. the X-47B aircraft can take off and land from an aircraft carrier. According to Popular Science, "The jet-powered, autonomous X-47B is designed for aerodynamic flight — it doesn’t even have a tail — partly to improve its stealth capabilities. But until now, its flight tests hadn’t retracted the landing gear, making it difficult to test its aerodynamic attributes. Further tests will help engineers prove the aircraft’s performance under a wide range of altitude, speed and fuel conditions."
