The U.S. Air Force has awarded a $13.6 million contract to Tennessee-based Minco Technologies to design and demonstrate a breakthrough drone propulsion system that promises substantial fuel efficiency gains. Officially named the Modular Operationally Resilient Fuel-Flexible Extreme-Efficiency UAS-Engine System, the project aims to reduce logistical fuel demands by 50 percent, offering major strategic and operational advantages. The contract, managed through the Pentagon, specifies that development will occur at Minco’s facility in Cookeville, Tennessee, with completion targeted for August 2028. Although technical details remain classified, the effort centers on building a resilient, fuel-flexible engine optimized for endurance and adaptability in contested environments. This capability will enable unmanned systems to sustain longer missions, operate farther from supply bases, and function effectively across diverse theaters of operation. The engine’s design allows compatibility with multiple fuel types, reinforcing the U.S. military’s goal of reducing supply-chain vulnerabilities during forward operations. By minimizing refueling requirements, the system enhances deployment range, mission flexibility, and survivability of unmanned aerial assets. The initiative forms part of the Air Force’s broader strategy to advance energy-efficient propulsion technologies across its unmanned fleet. Similar energy resilience efforts are also underway in NATO. For example, five alliance members have recently procured hybrid power systems for their Patriot air defense units, designed to cut refueling needs by threefold per battalion. Germany’s defense firm VINCORION is producing these systems to reduce resupply exposure and operational risks. Collectively, these advancements highlight a shared Western defense focus on logistical efficiency, energy independence, and sustainable operational readiness in future combat environments.
