The decision allows the F-35, F-16 and C-130 fleets to operate using synthetic fuel blends of up to 50%, in line with current flight manual authorisations. The blend limit varies depending on the raw materials and production pathways used in the synthetic fuel.
Lockheed Martin completed a thorough technical and strategic assessment to confirm that SATF meets the high standards required for mission readiness in varied and demanding conditions. This move also supports the U.S. Department of Defense’s energy substitution and diversification goals.
SATFs are produced from both fossil-based and renewable sources, including coal, natural gas, waste oils, and agricultural residues. Their use offers environmental advantages and reduces logistical dependency on conventional fuel sources.
“The F-16 is the world’s most combat-proven 4th generation fighter, delivering decisive capability across air-to-air, strike, and close air support missions,” said Mike Shoemaker, vice president and general manager of the Integrated Fighter Group at Lockheed Martin. “Synthetic fuels compatibility ensures the F-16 remains ready to meet evolving operational demands, strengthens global fuel flexibility and keeps this critical platform at the forefront of allied airpower.”
The C-130 Hercules, currently operated by 28 forces in 23 countries, is recognised for its adaptability and mission-critical performance. Lockheed Martin highlighted the aircraft’s continued evolution in response to changing global security needs.
“The C-130 is proven in every environment and has earned the trust of more nations than any other tactical airlifter,” said Rod McLean, vice president and general manager of the Air Mobility & Maritime Missions line of business. “Approving synthetic fuels for the C-130 is more than an engineering milestone — it represents an environmental advantage from a reduced carbon emission perspective and reflects our commitment to ensuring this leading aircraft remains at the forefront of mission readiness, energy resilience and global interoperability for decades to come.”
