USAF Signals Major Shift Toward Autonomous Next-Gen Aerial Refueling Fleet
Air Mobility Command leadership is evaluating uncrewed and optionally manned architectures for the Air Force’s Next-Generation Air Refueling System. This strategic pivot aims to address growing combat range requirements and survivability in contested environments.
The U.S. Air Force is considering uncrewed or optionally manned platforms for its Next-Generation Air Refueling System (NGAS), marking a potential operational pivot in strategic air mobility and force projection. Speaking at the Air Force Association’s Air, Space & Cyber Conference, Lt. Gen. Daniel Tulley, commander of Air Mobility Command (AMC), indicated that the service’s long-term answer to replacing its aging KC-135 Stratotanker fleet does not strictly require a traditional manned flight crew. As the Air Force proceeds with an Analysis of Alternatives for mid-2030s deployment—evaluating blended wing-body concepts, stealthy geometries, and expanded KC-46 Pegasus buys—the integration of high-capacity uncrewed tanker variants has emerged as a core operational concept.
This shift underscores a broader Department of Defense imperative to project persistent power across vast operational distances, such as the Indo-Pacific, without putting human crews at risk in highly contested airspace. While the U.S. Navy has demonstrated carrier-based uncrewed refueling via Boeing’s MQ-25 Stingray, scaling uncrewed aerial refueling to meet Air Force operational requirements presents severe engineering challenges. A standard KC-46 carries over 212,000 pounds of fuel—more than 15 times the capacity of the MQ-25. Achieving autonomous operation at this payload scale demands robust, resilient, and cyber-hardened command-and-control architectures capable of operating reliably under aggressive Electronic Warfare (EW) and denied-communications scenarios.
