The Navy’s UFO-Like ultimate stealth fighter drone X-47B, from Northrop Grumman, has achieved a new milestone — it flew in cruise configuration for the first time, stowing its landing gear for a streamlined flight.
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.
