On December 9, 2020, Boeing and the U.S. Navy flew the MQ-25 T1 test asset with an aerial refueling store (ARS) for the first time, a significant milestone informing development of the unmanned aerial refueler. The successful 2.5-hour flight with the Cobham ARS – the same ARS currently used by F/A-18s for air-to-air refueling – was designed to test the aircraft’s aerodynamics with the ARS mounted under the wing. The flight was conducted by Boeing test pilots operating from a ground control station at MidAmerica St. Louis Airport in Mascoutah, Ill. Future flights will continue to test the aerodynamics of the aircraft and the ARS at various points of the flight envelope, eventually progressing to extension and retraction of the hose and drogue used for refueling.
