In a sobering admission that confirms the fears of many Pentagon planners, U.S. Air Force Chief of Staff General David Allvin has publicly stated that the nation’s next-generation F-47 fighter is not scheduled to fly until 2028. This new, explicit timeline is a critical development, as it means the American program is already running three to four years behind its Chinese rivals, who reportedly began flight testing two separate sixth-generation designs in late 2024.
The news, confirmed by General Allvin on November 12, resets expectations for a program that had previously been aimed for flight testing before the end of President Donald Trump’s term in January 2029. This confirmation follows a period of intense uncertainty for the F-47, which faced severe funding shortages until China’s sudden display of its advanced prototypes spurred the new administration to strongly back the program.
A New Timeline and a Sobering Reality
The 2028 date for a first flight is a hard dose of reality for an Air Force that has defined global air superiority for decades. General Allvin, speaking at an Air & Space Forces Association event, confirmed that while the F-47 (the centerpiece of the Next Generation Air Dominance, or NGAD, program) is now being built, its 2028 flight target is the new benchmark.
This timeline is particularly alarming when contrasted with China’s progress. The first flights of two separate Chinese sixth-generation fighters in December 2024 were a technological shock. That event is now credited with saving the F-47 program, which was on the chopping block due to budget constraints. Now, the race is on, but the U.S. is starting from behind.
The ‘Decade Gap’: A Worrying Precedent
The three-to-four-year gap in flight testing is not the real story. The terrifying prospect for U.S. warfighters is the fielding gap. China’s defense industry has proven it can move from prototype to production at a blistering pace.
A stark, unfavorable precedent haunts the Pentagon: China’s first fifth-generation fighter, the J-20, went from its first demonstrator flight to active service entry in just six years. By contrast, the American F-22 and F-35 programs both took 15 years to cover the same ground.
If China’s timeline holds, its sixth-generation fighters could be operational and rolling off production lines by 2030 or 2031. If the U.S. flies the F-47 in 2028 and follows its own 15-year precedent, it might not field a comparable fighter until 2043. Even in a best-case scenario, China could possess a dominant, next-generation fleet for the better part of a decade before America has an answer.
‘The Adversary is Not Taking a Knee’
This is precisely the scenario that has kept U.S. commanders awake at night. In September 2022, General Mark Kelly, then-head of Air Combat Command, warned that China was “on track” to field its next-generation fighter first. General Allvin echoed this urgency, noting, “The adversary is not taking a knee. They’re not stopping… that’s not what they’re doing.”
With Russia’s Su-57 program producing a less advanced jet in tiny numbers, and Japanese-British programs still in early stages, experts are clear: this is a two-horse race. The complexity and cost of sixth-generation technology have ensured that only the U.S. and China are truly in the running.
An Internal Dogfight: Air Force vs. Navy
The renewed political will to fund the F-47 program has come at a steep price for another, arguably more urgent, program: the U.S. Navy’s F/A-XX. This parallel program is meant to develop a sixth-generation fighter to operate from America’s aircraft carriers.
The Pentagon, facing budget realities, has effectively been forced to prioritize the Air Force’s F-47 at the expense of the Navy’s F/A-XX. This is a dangerous gamble. While the Air Force possesses a robust fleet of fifth-generation F-22s and F-35s, the Navy is still heavily reliant on its 4th-generation F/A-18E/F Super Hornets. China’s rapid naval expansion means the U.S. Navy desperately needs a next-generation fighter to maintain its edge at sea, making its need even more pressing than the Air Force’s.
The Ghost of the F-35
This budget-driven rivalry has raised the dreaded prospect of a forced joint program, which gave the Pentagon the F-35. While a single program to serve both services sounds efficient on paper, the F-35 proved to be a cautionary tale.
The F-35’s three variants—one each for the Air Force, Navy, and Marines—ultimately shared less than 20% commonality. This “joint” program became three separate, hideously expensive aircraft development programs under one banner. If the services are forced down this path again, it could lead to disastrous delays. But if they aren’t, the U.S. Navy may be left without a sixth-generation fighter, creating a future where American carrier air wings are outmatched by their Chinese adversaries.
