21st Century
On 4 June 2021, the first refuelling test and evaluation flight was conducted with the MQ-25 drone refuelling aircraft providing fuel to an F/A-18E/F Super Hornet. The test had the MQ-25 originate at MidAmerica Airport in Mascoutah, Illinois, and the F/A-18 was from the VX-23. The mission lasted about 4.5 hours, and the two aircraft were connected for dry or wet connects numerous times for a total time of more than 10 minutes, with a total of 325 pounds of fuel passed.
