Boeing and the U.S. Navy have for the first time flown the MQ-25 T1 test asset with an aerial refueling store (ARS), 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.
The Boeing-owned T1 test asset is a predecessor to the engineering development model aircraft being produced under a 2018 contract award. T1 is being used for early learning and discovery, laying the foundation for moving rapidly into development and test of the MQ-25. Following its first flight last year, T1 accumulated approximately 30 hours in the air before the planned modification to install the ARS.
Earlier this year the Navy exercised an option for three additional MQ-25 air vehicles, bringing the total aircraft Boeing is initially producing to seven. The Navy intends to procure more than 70 aircraft, which will assume the tanking role currently performed by F/A-18s, allowing for better use of the combat strike fighters.
