The X-47B made its first flight in 2011 and has since undergone extensive testing. It is notable for its ability to take off and land autonomously on aircraft carriers, showcasing the potential for future unmanned systems in military aviation. The program aims to enhance naval capabilities and reduce risks to human pilots.
