WASHINGTON — The U.S. Air Force is preparing to radically alter the acquisition strategy for its next generation of fighter jets, with a new plan that could require industry to design, develop and produce a new fighter in five years or less.
On Oct. 1, the service will officially reshape its next-generation fighter program, known as Next Generation Air Dominance, or NGAD, Will Roper, the Air Force’s acquisition executive, said during an exclusive interview with Defense News.
Under a new office headed by a yet-unnamed program manager, the NGAD program will adopt a rapid approach to developing small batches of fighters with multiple companies, much like the Century Series of aircraft built in the 1950s, Roper said.
“Based on what industry thinks they can do and what my team will tell me, we will need to set a cadence of how fast we think we build a new airplane from scratch. Right now, my estimate is five years. I may be wrong,” he said. “I’m hoping we can get faster than that — I think that will be insufficient in the long term [to meet future threats] — but five years is so much better than where we are now with normal acquisitionThe Century Series approach would be a notable departure from the Air Force’s former thinking on its future fighter. In its “Air Superiority 2030” study released in 2016, the Air Force described a long-range, stealthy sensor-shooter called “Penetrating Counter Air,” which would act as NGAD’s central node networked with sensors, drones and other platforms. The Air Force would use prototyping to speed along key technologies in the hope of maturing them early enough for inclusion in advanced aircraft fielded in the early 2030s.

But if a Digital Century Series construct is adopted, the Air Force may pay companies more money upfront during the design phase and require them to produce planes with a shorter design life; for instance, a jet with a lifespan of 6,000 flight hours instead of manufacturing aircraft designed to be kept in the skies for 20,000 hours, Roper said.
“That opens up the opportunities to do things very differently, different structural designs, not doing full-scale fatigue testing and all of things we do on the geriatric Air Force to keep things flying,” he said. “Where is the sweet spot where we are keeping airplanes long enough to make a real difference but not so long that we’re paying a premium to sustain them or not able to refresh them with better aircraft?”
One obstacle to the Digital Century Series approach may be persuading Congress to approve the necessary funding. The House Armed Services Committee already recommended cutting funding for the NGAD program in the fiscal 2020 budget request, from $1 billion to $500 million — a sign that the committee may not be sold on the Air Force’s path forward.
Roper said the idea has generated a “good response” from the congressional defense committees but acknowledged that lawmakers have questions about the approach. He also noted there will need to be a means to pay the bills, particularly in the early stages of the development cycle when multiple companies are on contract to design aircraft.
“I think the theory is sound, it’s the funding required and how big of an industry base we can sustain,” he said. “I don’t want to leave companies out, but I also don’t want to go so big that we fail because of funding, not because of the soundness of the idea
