U.S. Air Force recommends continuing NGAD fighter development and ending NGAS tanker project

The NGAD programme, which has been under extensive review, is now expected to proceed as a key part of the USAF’s future force structure. In contrast, the NGAS tanker, initially designed to refuel NGAD aircraft in contested airspace, has been deemed unnecessary if the NGAD fighter possesses a significantly extended operational range.

A major factor in this decision is the USAF’s ability to ensure survivable aerial refuelling without investing in a costly stealth tanker. Existing KC-46 Pegasus tankers, operating from safer locations, could be supplemented by unmanned systems like the MQ-25 Stingray to extend the range of combat aircraft at a lower cost.

The NGAS programme emerged as part of a long-term strategy to replace the ageing fleet of KC-135 and KC-10 tankers. Initially envisioned as a highly survivable aerial refuelling platform, NGAS would have required advanced stealth features and autonomy, increasing its cost significantly.

USAF officials highlighted concerns that adversaries could develop capabilities to detect and target large refuelling aircraft, making the investment in stealth tankers less viable. Instead, the Air Force plans to focus on disrupting enemy kill chains and employing alternative survivability measures to protect traditional tanker operations.

The decision to halt NGAS reflects broader budgetary pressures, as the USAF must prioritise funding for other critical programmes. These include the B-21 Raider stealth bomber, the Sentinel intercontinental ballistic missile (ICBM), hypersonic weapons, collaborative combat aircraft (CCA) drones, and the NGAD fighter itself.

While the USAF’s recommendation is influential, the final decision on NGAD and NGAS will rest with policymakers. The outcome will likely be shaped by the fiscal year 2026 budget, which is being finalised under the new Trump administration and will determine future defence priorities.
