The link posted by @RcouF1uZ4gsC contains a graphic that shows a 'refuel' point over the mid-Atlantic and the linked article says this: > ...it needed a minimum of one in-flight refueling, thanks to the astonishing amount of fuel it consumed while in afterburner. ... Having already surged across the Atlantic in a sustained supersonic cruise at speeds in excess of Mach 2.5-2.6 ... Sullivan began a descent that would bring him to the only refueling point of their mission. After tanking up, the duo climbed away and once again nudged the throttles ahead. The time taken up by the in-flight refueling was deemed virtually negligible when the Blackbird flew through the London gates. So, according to the linked article from @RcouF1uZ4gsC, yes, the record time included one refuel during the NY to London route.
