The Air Force has flown, for the first time, a C-17 entirely fueled by a synthetic fuel blend in all four fuel tanks. An earlier flight had demonstrated the use of the Fischer-Tropsch synthetic and JP-8 blend in one tank. After the Oct. 22 flight, the lead pilot for the test, Maj. Scott Sullivan, with the Air Force Flight Test Center at Edwards AFB, Calif., said, “There was no discernible difference between” the pure jet fuel and synthetic blend. The Air Force expects to certify the synfuel blend for the entire C-17 airlifter fleet early next year. It certified the B-52 bomber fleet in August. Some analysts question whether there will be enough synthetic fuel production to meet the service’s needs.
Boeing received a $2.47 billion Air Force contract Nov. 25 for 15 more KC-46s, bringing to 183 the number of Pegasus tankers on contract to all customers, foreign and domestic. The new contract—for Lot 12 of the initially planned KC-46 buy—is to be completed by 2029.
