Edwards F-22 Raptor performs aerial refueling using synthetic fuel
An Edwards F-22 Raptor receives synthetic fuel from a KC-135 Stratotanker during an aerial refueling test using an alternative jet engine fuel Aug. 28. Organizations involved in this endeavor include the 411th Flight Test Squadron, Air Force Research Laboratory, Lockheed Martin, Boeing, Pratt and Whitney, and Honeywell. The test was done as part of the Secretary of the Air Force’s initiative to certify the entire fleet on synthetic fuel, an effort to lessen foreign dependence on oil. (Lockheed Martin photo)
