Refueling from above

A KC-135 Stratotanker from Fairchild Air Force Base, Boeing and the 418th Flight Test Squadron are conducting Ground Effects and Fuel Onload Fatigue testing on the new KC-46. Fuel Onload Fatigue is gathering data to characterize the aircraft interaction typically experienced when the KC-46A is flying in receiver formation behind a current KC-135 or KC-10 tanker. While the KC-46's role is to refuel other aircraft, it itself may need refuel from other KC-10s or KC-135s to extend its range. Fuel Onload Fatigue testing is the first look at the KC-46 acting in that role. (U.S. Air Force photo/Christopher Okula)
