DefenseU.S. Air Force Opens Range of Possibilities for Next-Generation Tanker Aircraft
The US Air Force (USAF) is intensifying efforts to define the requirements and design of its next-generation aerial refueling platform under the Next Generation Air-refueling System (NGAS) program. Initiated in 2023, the initiative aims to identify a future tanker capable of operating in increasingly contested environments.
While NGAS was initially conceived as a stealth tanker, the Air Force has expanded its analysis to include a range of configurations. According to Gen. John Lamontagne, all possibilities are being considered, from conventional tanker aircraft to designs based on business jets and Blended-Wing-Body (BWB) fuselage concepts. This broad approach seeks to address survivability, efficiency, and cost-effectiveness.
Technical assessments now include not only stealth features but also a systems-based survivability approach. Options under review incorporate electronic warfare capabilities to enhance resilience in hostile airspace. The program has not extensively evaluated fully autonomous tanker platforms similar to the Navy’s MQ-25 Stingray.
Cost remains a significant factor in the NGAS roadmap. The Air Force issued a Request for Information (RFI) in August to gather updated cost estimates and inform its ongoing analysis of alternatives. Industry responses to the RFI are due by October, after which the service will continue refining its strategy and fleet planning.
The outcome of the latest market survey is expected to clarify the feasibility of various low-observable and survivability solutions for future tankers. The Air Force plans to use these insights to shape the NGAS program and maintain the operational health of its current tanker fleet.
Meanwhile, the service has been seeking approval for an extension of the KC-46A Pegasus contract with Boeing, but has encountered resistance from some in the U.S. Congress, which fears the aircraft’s reliability.
A recent bill approved by Congress prevents the USAF from ordering more KC-46s while halting the retirement of aging KC-135s and keeping KC-10 tankers in reserve.
