The US Navy (USN) and Boeing used the MQ-25A Stingray unmanned aerial vehicle to pass fuel to a Lockheed Martin F-35C Lightning II Joint Strike Fighter receiver aircraft for the first time on 13 September.

During the three-hour flight, a USN F-35C pilot from Air Test Wing and Evaluation Squadron Two Three (VX-23) approached the Boeing-owned test asset Stingray, MQ-25 T1, and performed formation evaluations, wake surveys, and drogue tracking. It then plugged with the T1 at 225 kt calibrated airspeed at 10,000 ft altitude, according to a USN statement.

Boeing spokesperson Ashlee Erwin said on 14 September that 125 kg of fuel was transferred in approximately 10 seconds. She noted that this amount of fuel was a test offload similar to other refuelling flights the company has performed with the T1, and that operational refuelling will involve greater quantities of fuel.
