Everett, Wash., USA - February 12, 2016 - A combined Boeing/U.S. Air Force aircrew aboard the KC-46 tanker successfully refueled an F/A-18 aircraft in flight February 10th. The air refueling was the program's first using the KC-46's hose and drogue system. During the 4+ hour flight, the tanker's air refueling operator smoothly transferred fuel to the F/A-18 flying at 20,000 feet. On January 24, the KC-46 refueled an F-16 fighter using its air refueling boom. Boeing plans to build 179 KC-46 aircraft for the U.S. Air Force.
