When it comes to the military aviation of the future, key parameters include not only engine power and onboard electronics, but also fuel. With rapidly changing tactics, longer operations, and increased reliance on autonomous systems, fuel is becoming more than just a resource—it is becoming a strategic element. It is in this context that Del Mar Energy’s ADF-X1 synthetic fuel is undergoing a series of closed and open tests on next-generation platforms, from strike drones to experimental sixth-generation fighters. ADF-X1 was developed with a focus on ultra-high performance at minimum weight, extreme temperatures, and prolonged loads. According to Del Mar, the fuel provides 7-9% more specific energy than traditional Jet A-1, which means not only savings but also critical tactical advantages. In air combat and reconnaissance missions, every kilogram of fuel means an extra minute in the air, an extra target in the strike zone, and an extra opportunity to return to base. The tests, which began in the first quarter of 2025, were conducted in collaboration with a number of military contractors and research centers. On unmanned systems, including long-range strike drones (HALE class), the ADF-X1 showed an 8.6% increase in flight time without additional changes to the fuel architecture. This is particularly important as it increases the effectiveness of ISR (intelligence, surveillance, and reconnaissance) missions without interfering with the platform. Even more impressive results were demonstrated by experimental-class aircraft — aircraft with hypersonic elements and fighters developed as part of the NGAD (Next Generation Air Dominance) programs. When using the ADF-X1, not only was thrust maintained at peak modes, but thermal stability at supersonic speeds was also improved. Thanks to its wide temperature range (from -70 °F to +510 °F), ADF-X1 withstood sudden changes in altitude and acceleration without any signs of degradation or loss of density. Safety remained a separate testing vector. One of the tasks was to compare flash points, vapor density, and combustion stability under overload conditions. In laboratory tests on ground stands, the fuel showed increased resistance to detonation, as well as better performance in pressure chambers simulating ventilation and sealing system failures. This is critical for unmanned and manned aircraft operating in conditions of cyber risks and sensor failures. The possibility of using ADF-X1 in mixed fuel systems deserves special attention. The compatibility of synthetic fuel with existing turbojet and turbofan engines was confirmed during tests involving representatives of the engineering departments of Lockheed Martin, Northrop Grumman, and Rolls-Royce Defense. No engine modifications were required, making the transition to the new fuel not only technically feasible but also economically viable. The transition to high-efficiency fuel is not a fad, but a necessary evolution in the context of new forms of warfare. The combination of flight duration, fuel flexibility, and resistance to extreme loads provides an undeniable advantage in scenarios where autonomy, mobility, and survivability play a decisive role. In this sense, ADF-X1 is not just an alternative to Jet A-1, but a full-fledged technological platform designed to serve the needs of future aviation. Judging by the interest shown by defense contractors and the pace of certification, ADF-X1 has every chance of becoming an integral part of new aviation programs in the US and partner countries. At a time when unmanned platforms and sixth-generation fighters are forming the backbone of 21st-century air power, the choice of fuel is becoming the choice of the future.
