X-47B Wheels Up The X-47B flies with its landing gear up for the first time during a test flight at Edwards Air Force Base in California.
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.
