Norwegian F-35 Joint Strike Fighters have flown for the first time with sustainable aviation fuel, leading jet-maker Lockheed Martin today to approve the use of similar fuels in the F-35.
Lockheed Martin’s approval, or “no technical objection,” paves the way for F-35 fuel tanks to be filled with up to 50% synthetic aviation turbine fuels, the company announced today. SATFs could be made from other fossil fuels including coal and natural gas or from renewable and sustainable sources including waste oils and agricultural residues.
Using SATFs would support the Defense Department’s goals for energy substitution and diversification, the company stated.
“Lockheed Martin is committed to ensuring the F-35 is always ready for any customer mission,” said Chauncey McIntosh, vice president and general manager of the F-35 program at Lockheed Martin. “Adding new fuel sources helps make this happen by diversifying the supply chain while maintaining operational excellence. As the cornerstone of the joint fleet, the F-35 will continue to lead the U.S. and allied air dominance mission for decades to come."
The Norwegian Air Force was the first to fly the jet with alternative fuel. In a news release, the service said the fuel it used contained synthetic aviation fuels, biofuels and other recycled carbon sources.
“The measure marks a change of pace towards greener solutions in the defence sector and contributed to the government’s goal of cutting emissions while maintaining operational capacity and preparedness,” the release states.
