The X-47 took on over 4,000 pounds of fuel from an Omega Aerial Refueling Services K-707 while flying over the waters of the Maryland and Virginia coasts, Navy Times reports. The drone took off from Naval Air Station Patuxent River in Maryland.
"The ability to autonomously transfer and receive fuel in flight will increase the range and flexibility of future unmanned aircraft platforms, ultimately extending carrier power projection," Capt. Beau Duarte, the X-47B's program manager, told NT.
