So far, five flights have been carried out and there will be a total of 20 flights. The final trail is scheduled to occur in mid-June.
The 2015 DOT&E report on the F-35 program noted that the B-variant of the F-35 is unable to take fuel from the wing pods of KC-10 and KC-135. It is unknown whether this was a factor in deploying the Voyager to the United States.
