The NGAS program was launched in 2023, with previous RFIs focusing on propulsion and mission systems. While the original concept envisioned a purpose-built, low-observable tanker capable of operating in contested airspace, the Air Force appears to be adopting a more flexible approach to survivability and mission effectiveness.
At the time of the initial solicitation, then–Air Force Secretary Frank Kendall stressed the need for purpose-built survivable platforms. “Traditionally, we could take a commercial grade of aircraft and turn it into a tanker or transport,” Kendall noted. “They’re not designed with a high set of requirements for survivability or resilience, and the threats are taking that freedom away from us.”
Kendall had previously accelerated the program to field an NGAS aircraft by the mid-2030s. Two years later, however, with Kendall out of office, Air Force leaders are considering a systems-based approach, potentially combining conventional tankers with electronic warfare, uncrewed fighters, or sixth-generation aircraft.
Speaking at an Air and Space Forces Association (AFA) event in March, Major General Joseph Kunkel suggested the service could pursue survivability without a bespoke stealth tanker. The Air Mobility Command also noted the Air Force is nearly finished with a formal analysis of alternatives to evaluate operational effectiveness, suitability, and lifecycle cost for the future refueling fleet.
Senior leaders are expected to provide further details on NGAS at the AFA’s annual Air, Space, Cyber conference in September. In the meantime, the Air Force confirmed in July that it will increase its purchase of Boeing KC-46 refueling aircraft from 179 to 263, solidifying its medium-term modernization strategy.
The decision to expand the KC-46 fleet effectively ended the proposed “bridge tanker” program, a setback for Lockheed Martin’s Airbus A330-based LMXT. However, the evolving NGAS requirements may create new opportunities for industry competitors such as JetZero, which is developing its Z4 blended-wing body demonstrator with Northrop Grumman support, and Embraer, which continues to seek a U.S. entry for its KC-390 tanker/transport.
