Boeing’s KC-46 tanker program has completed its planned Phase II receiver certification flight testing following three weeks of flights with F-15E aircraft out of Edwards Air Force Base, California.
Boeing and U.S. Air Force KC-46 crews kicked off receiver certification testing with F-16 aircraft in April 2018. Since then the joint team also completed testing with KC-135, C-17, A-10, KC-46, B-52, and F/A-18 aircraft.
During the certification flight tests, KC-46 and receiver aircraft flew at different airspeeds, altitudes and configurations to ensure compatibility and performance throughout the refueling envelope of each receiver. Now, the Air Force and the Aerial Refueling Certification Agency will review all test data and paperwork before ultimately “certifying” each aircraft.
Six test aircraft have now completed more than 3,700 flight hours and supplied more than four million pounds of fuel in flight to receiver aircraft.
