Northrop Grumman X-47B Demonstrates Unmanned Aerial Refueling for the First Time

In April 2015, Northrop Grumman’s X-47B Unmanned Combat Air Vehicle Demonstrator successfully completed an autonomous aerial refueling (AAR) test by plugging into an aerial refueling basket behind an Omega Air KC-707. The Salty Dog 502, one of the two UCAS-D aircraft of the X-47B program, was the aircraft that performed the test off the coast of Maryland. Originally, the aircraft was not going to receive funding for aerial refueling, but the money ended up coming through for what is slated to be the final test of the historic X-47B.

The AAR in set to be the last for the two X-47B stealth killer drone technology demonstrators (the other being “Salty Dog 501?). At the end of this testing phase, the two unmanned aircraft will be retired and probably donated to a museum or stored at the “boneyard”, the Aerospace Maintenance and Regeneration Group (AMARG) at Davis-Monthan Air Force Base, Arizona. In fact, the X-47B is just a technology demonstrator and, as such, it’s still quite different from the planned Navy’s Unmanned Carrier Launched Surveillance and Strike (UCLASS).
