PATUXENT RIVER, Md. (Jan. 11, 2024) Air Test and Evaluation Squadron (VX) 23 flies an F/A-18F Hornet alongside a German air force A400M Atlas during an air-to-air refueling test aimed at expanding the flight envelope for the European transport and tanker aircraft. VX-23 is flying to clear the entire envelope for all NATO allies flying Atlas, which will allow it to refuel American Hornet, Growler, and Harrier aircraft, ultimately expanding the United States' ability to operate its forces globally.
