A top U.S. Air Force acquisition officer says work to set up a full production line for the F-47 sixth-generation fighter is getting closer and closer on the horizon. Prime contractor Boeing is in the midst of a nearly $2 billion expansion to its facilities in St. Louis, Missouri. The F-47 program otherwise continues to progress along an aggressive schedule, with a first flight still being targeted for 2028 and the goal of production jets entering operational service in the early 2030s.

Air Force Brig. Gen. Timothy Helfrich, the service’s Portfolio Acquisition Executive for Fighters and Advanced Aircraft, provided an update on the F-47 program during a virtual talk hosted by the Air & Space Forces Association’s Mitchell Institute for Aerospace Studies yesterday. Boeing won the Air Force competition to produce the F-47 in March 2023, and at least one pre-production example is being built now. The Air Force’s stated plan now is to acquire at least 185 of these jets.

“We have an imperative, I would call it a strategic asset, which is fighter production capacity,” Helfrich said during his opening remarks. “We only have so many production lines, and so we have to get the very most out of those that we can while planning for CCA [Collaborative Combat Aircraft drone] production, and pretty soon F-47 production.”

“There are only three active fighter production lines, right? We got F-35 down in Fort Worth, the F-15EX in St. Louis, and F-16 in Greenville,” Helfrich elaborated later on in the discussion in response to a question about steps the Air Force is taking to maintain sufficient operational capacity across its fighter fleets, in general. “So we need to grow the existing production lines, and we need to – or at least maximize what we can get out of those existing production lines, and we need to add production lines.”

“We’re not too far away from an F-47 production line, which will be additive to the production capacity,” he added.

Since 2023, Boeing has been working to substantially expand its production and other facilities in St. Louis by more than one million square feet. The company has repeatedly shied away from explicitly linking the $1.8 billion construction project to the F-47 program, but there have been clear signs of a connection for years now.

“The project’s first phase includes plans to erect and renovate 1.1 million ft.2 of facilities on the 110-acre Brownleigh and 75-acre Northern tracts adjacent to St. Louis Lambert International Airport, according to planning documents released by the airport authority in 2023,” Aviation Week reported in 2025. “Phase 1 includes the construction of a 880,000-ft.2 aircraft assembly building on the Brownleigh [site], plus a 185,000-ft.2 hangar, 80,000-ft.2 radar cross-section test facility, open aircraft shelters, hush house, maintenance building, fuel calibration building and fire house totaling 90,000 ft.2 on the Northern tract.”

At that time, parts of the new facility were reportedly expected to open in 2026 ahead of the completion of the full project in 2030.

A post across Boeing’s social media accounts in July highlighted continued progress with this construction. This included the completion of roof and exterior panels and the installation of hangar doors at a section of the site dedicated to “Advanced Combat Aircraft Assembly,” as well as the “first steel column installed for the Central Utility Plan” in the North Tract area.

Progress you can see. Built for what's next.

“Momentum continues on our St. Louis expansion,” Dan Gillian, Vice President and General Manager of Air Dominance at Boeing, also said in July, according to Flight Global. “We are expanding our defence footprint while supporting next-generation capabilities.”

All of this is in line with Brig. Gen. Helfrich’s comments yesterday about a full production line for the F-47 steadily taking shape now. This, in turn, fits squarely with the aforementioned aggressive timeline the Air Force is pursuing for the program overall. Accelerated work on the F-47 has been aided by years of flight testing in secret of advanced demonstrator aircraft.

There is also a question of whether Boeing’s expansion of its production capacity in St. Louis could also be tied to the Navy’s F/A-XX next-generation carrier-based fighter program. Boeing has been facing off against Northrop Grumman in the F/A-XX competition with a design that looks related, at least to some degree, to the F-47.

The F-47 and F/A-XX programs have become very closely intertwined in other ways. In 2025, the Pentagon moved to freeze F/A-XX, explicitly over concerns about competition for industrial base resources with F-47. This would include production line capacity. Congress subsequently intervened to keep the Navy effort going, but a final winner still has yet to be announced.

Just earlier this month, Air Force Gen. Dale White, the service’s Direct Reporting Portfolio Manager for Critical Major Weapon Systems, reiterated concerns about industrial capacity. White’s comments came in response to a question about potential challenges in building F/A-XXs at the same time as F-47s at a media roundtable at the Air & Space Forces’ Air, Space and Cyber Conference at which TWZ was in attendance. The general also acknowledged that these concerns were “not unique” to F/A-XX and F-47.

During the virtual talk yesterday, Brig. Gen. Helfrich otherwise touted continued progress on the F-47 program.

“The F-47 is going to be the world’s first sixth-generation fighter, and I can’t wait to fly it [sic; see it fly] this administration,” he said. “That’s a commitment that I made, that we are on track to do.”

The “administration” referred to here is President Donald Trump’s second term in office, which will come to a close in January 2029. With this deadline in mind, the Air Force has openly said in the past that it is aiming for a first flight of the F-47 in 2028. Beyond that, the stated goal is to be operating the jets operationally sometime in the early 2030s.

As noted, the Air Force has said previously that it is planning to acquire a fleet of at least 185 F-47s, which is in line with the original vision of the aircraft as a direct successor to the F-22 Raptor. However, there have already been signs that the final F-47 fleet figure could grow amid an evolving view of the F-22’s continued role in the near-term. A huge, multi-faceted modernization effort for the F-22 fleet is now underway, as you can read more about here.

When the jets do enter service, “one of the things that we know F-47 is going to bring is more survivability and lethality than anything that’s ever been delivered before. And going into that highly contested environment, you have to meet certain levels of survivability if you want to execute there,” Helfrich noted yesterday. “Beyond just the survivability and lethality that we know is going to come, there’s also an adaptability that the F-47 will bring.”

“The F-47 will come out of the box with full open architecture,” he continued. “Amongst other great things, it brings the ability to upgrade rapidly, faster than the threat if needed. That is what is going to be required in that kind of environment. Other things it’s going to bring, it’s going to be much more survivable than our fifth-gen platforms, as well as have a combat radius of over 1,000 nautical miles, which you’re familiar with. That’s a long way, which is needed for that kind of environment. You need to be able to execute and persist there.”

“Especially in these highly contested environments, no one’s going to be fighting alone. So we need to make sure that we are integrating,” he added. “There’s some ability to get lift from one platform to another, right? Whether it’s a mission system, it’s communications, it’s open architectures, we’re seeing that integration pay dividends, so that we are integrated from day one.”

This kind of integration and cross-platform commonality in mission systems will be particularly relevant for F-47s acting as airborne controllers for CCA drones. Brig. Gen. Helfrich’s comments above also came in the midst of a discussion about future operations involving both F-47s and B-21 Raider bombers.

Many questions do still remain about plans for the F-47 and its design, including what engines will power the aircraft when it first enters service. In July, TWZ published a deep-dive feature about what is known about the aircraft to date, which you can find here.

In the meantime, the Air Force and Boeing are continuing to push ahead with laying the groundwork for full production of the F-47 as the jet gets closer to its first flight in the coming years.

The post Full F-47 Production Line “Not Too Far Away”: USAF General appeared first on TWZ.

As both the Navy and the USAF were racing to field a new generation of advanced tactical jets, the seagoing service’s program hit a wall. A major reason behind this from the Pentagon was concern that the U.S. industrial base could not handle simultaneous final development and production of two extremely complex new fighter aircraft. This was a controversial justification that many had a hard time swallowing. The Navy’s program, dubbed F/A-XX, is supposedly back on and a down-select on who will build it is coming soon, but that concern appears to linger among at least one of the Department of War’s top acquisition officials.

Though he remains confident that the U.S. Air Force F-47 sixth-generation fighter will fly in the next two years, Air Force Gen. Dale R. White, Director, Critical Major Weapon Systems — the service’s leading weapons procurement advisor — remains concerned about the overall capacity of industry to provide the military with the aircraft it needs, including two new fighters. His comments were in response to questions about the Navy’s challenges in building its own sixth-gen fighter alongside F-47.

The concerns are “not unique” to the F-47 or the Navy’s program but the problem exists to various degrees across the industrial base too, White told reporters Tuesday during a media roundtable at the Air & Space Forces’ Air, Space and Cyber Conference that TWZ is attending.

White has a dual-hatted role, serving as the Pentagon’s top weapons procurement officer and as the senior acquisition advisor to the Secretary of the Air Force for all acquisition matters.

“We’re seeing it in multiple platforms,” said White, who did not elaborate. “And so what we’re having to do is, at some point, we’re having to make some trade space in between some of these.”

“I see Boeing making smart investments,” White said of the prime contractor of the F-47, selected for the U.S. Air Force’s Next Generation Air Dominance (NGAD) ‘fighter’ initiative. “They have a lot of CAPEX [capital expenditure] that they’re pouring in, but we have to get through the process of the design piece, getting that completed and closed out. Then we all hit some major milestones with things like flight tests and software and those things.”

“Really, it’s just being able to manage the overall resourcing as it relates to number one, people resources,” the general added. “Number two, when you start getting into the production conversation, do we have enough capacity to be able to produce at that rate? And so, by and large, I have concerns. I have concerns about the capacity of our industrial base, but they are not unique to F-47 or to any program.”

As for the F-47, White said the program “continues to progress exceptionally well.”

“As you know, many, many years in tech maturation and risk reduction gave us a tremendous head start on this program,” White explained. “Extremely proud of what the team has done, what they continue to do each and every day. We are still absolutely on [the] path to be able to hit the mark of flying within this administration. So we see no issues in front of us right now.”

While the first example of the F-47 has been in production for about a year now, the Navy has yet to even select a prime contractor for its next generation fighter. The current competitors for the F/A-XX are Boeing and Northrop Grumman. A decision was supposed to have been made by last month.

“The F/A-XX program remains on track, and we have no further information to provide at this time,” a Navy official told us last week.

Despite intervention from Congress, the next-generation carrier-based fighter has remained in question since the Pentagon moved to effectively shelve the program last year.

In response to a question from TWZ earlier this year, the Chief of Naval Operations acknowledged the uncertainty over the F/A-XX program.

“One of the challenges we’re seeing is, not only [are] our peer competitors improving their capability for anti-air, either air-to-air or surface-to-air, but the lower cost of entry of very capable weapons is also making more players on the field in which that level of stealth and technology is required,” Adm. Daryl Caudle told us back in April at the Sea-Air-Space 2026 exposition. “So this is not about the need for a peer adversary. This is just having an aircraft that can operate with a level of uncertainty and with the acceptable level of risk.”

With Boeing as a finalist, it is also possible that F/A-XX could be a variant of the F-47. As we noted in a past story, the Boeing render for its F/A-XX concept is remarkably similar to artwork for its F-47.

Likely a navalized F-47 variant as expected. https://t.co/4lZkpUjqfz

Last year, Steve Parker, Boeing Defense and Space CEO, said he didn’t see a problem with his company building both jets stating that this had been part of the strategy all along.

If this is the case, the company’s claim that it would not have a problem building both the Navy and Air Force next-generation fighters would make more sense. There are a number of advantages when it comes to establishing a high-degree of commonality between F/A-XX and F-47, although there would also be challenges, especially when it comes to getting the most out of a design that was not meant to operate from a carrier deck and scaling production up for both services. There is already significant sharing of elements of both the Navy’s and Air Force’s sixth-generation fighter programs. So commonality in some subsystems and interoperability are already baked in.

We should hopefully finally get a clearer picture in the coming weeks about the status of the F/A-XX and possibly the answer to who will actually build it, which will give us a better idea of what the industrial base impact actually will be.
