The US Air Force’s Biggest Problem Isn’t Russia Or China Anymore​

Synopsis: The U.S. Air Force is attempting a sweeping modernization push, replacing aging Cold War-era aircraft with next-generation systems meant to preserve air dominance into the mid-21st century. In fact, the Air Force’s biggest problem isn’t China or Russia, persay, but getting ready to deal with the modernization needs to tackle both nations if a war ever occurred.

-The effort spans NGAD’s sixth-generation “family of systems,” continued F-35A procurement, F-15EX buys as a near-term hedge, and the B-21 Raider stealth bomber—plus critical enablers like the KC-46 tanker and T-7 trainer.

-But the bill is enormous, and the “divest to invest” strategy is politically difficult as Congress resists retiring legacy fleets. With China modernizing quickly, the real question becomes not whether the Air Force can afford it—but how it can’t.

The Big Problem: Can the Air Force Afford NGAD, B-21, F-35, and F-15EX All at Once?​

In recent years, the United States Air Force has pushed ahead with an ambitious program to modernize nearly every primary aircraft type in its inventory – and despite budget pressures and schedule slippage, those efforts are moving ahead (essentially) as planned.

From next-generation fighters to stealth bombers and new trainer jets, the service is attempting to replace aging Cold War-era platforms with high-tech systems designed to maintain U.S. military dominance well into the mid-21st century.

Those efforts come as the fast pace of Chinese military growth becomes increasingly alarming, and as defense budgets constantly shift, forcing the Air Force and the Pentagon into a situation where affordability and strategic necessity are constantly at odds.

What the Air Force Is Buying – and What It Will Cost​

The U.S. Air Force’s Fiscal Year 2026 budget reflects the scale of the ongoing investments. The service requested approximately $209.6 billion to operate and modernize its forces – an increase of nearly $25 billion over the previous year – with significant funds earmarked for new aircraft procurement and research and development.

At the heart of the modernization is the Next Generation Air Dominance (NGAD) program – a sixth-generation fighter family of systems that includes both a crewed fighter and a fleet of connected unmanned “loyal wingman” drones.

NGAD has been repeatedly framed by Air Force leadership as essential to countering advanced adversary air defenses and maintaining air superiority, which by all measures it is – but details on cost and procurement numbers are still far off from being accurate or confirmed.

Industry reporting and analysis have suggested that the program will be one of the most expensive in Air Force history, with estimates that individual platforms could cost more than existing fighters to procure and operate.

And that seems perfectly likely, given the cutting-edge technologies that will need to be integrated at scale.

Meanwhile, the Air Force’s current fighter fleet modernization efforts include the Lockheed Martin F-35A Lightning II. In the FY2025 defense budget, the Pentagon asked for roughly $12.4 billion to procure F-35 aircraft and support ongoing development, including 42 F-35As for the Air Force.

The Joint Strike Fighter Program – which birthed the F-35 – is the largest U.S. aircraft procurement effort ever undertaken, with total development and production costs projected at more than $485 billion for thousands of jets across all services.

And alongside stealth fighters, the Air Force is also buying F-15EX Eagle II aircraft as a near-term hedge. The multirole jets are meant to replace aging F-15C/D models and are less expensive on a per-aircraft basis than stealth platforms – but that being said, the costs remain substantial.

Recent budget activity surrounding F-15EX purchases has indicated a cost of $3.1 billion for planned purchases of two dozen aircraft – an acquisition designed to maintain force structure while newer systems begin to enter service. Reports also suggest that the Air Force could increase F-15EX procurement to 36 jets annually with sufficient funding.

But arguably the most visible part of the modernization program is the B-21 Raider, in part because the aircraft and its predecessor, the B-2 Spirit, are so iconic.

The upcoming stealth bomber, intended to replace both the B-1 and B-2 fleets, is under development by Northrop Grumman and is designed to carry both conventional and nuclear weapons; the Air Force is already aiming for at least 100 aircraft.

Should analysts get their way, procurement could reach 200. Unit costs have been reported to be extraordinarily high, however, at as much as $800 million per aircraft – a figure that reflects the complexity of the program.

Lawmakers even approved an additional $1 billion in funding for bomber infrastructure to support construction and basing improvements.

Beyond fighters and bombers, the Air Force is also investing in support platforms like the KC-46A tanker, used for aerial refueling, and the T-7A Red Hawk trainer, designed to replace the decades-old T-38 fleet. These systems are critical to sustainment and force generation, but they add billions more to the overall cost of modernization.

Can the Air Force Afford It?​

With all that spending, it’s hard to ignore the question: Can we afford this?

Service leadership has repeatedly stressed the concept of “divest to invest,” arguing that retiring legacy aircraft is necessary to free up funds for advanced systems – but congressional resistance to retiring older platforms complicates the trade-off.

Budget pressure from other defense priorities is creating tension over funding allocation. In short: it’s a mess.

Some argue that the Air Force’s planned procurement rates still fall short of what would be needed to counter major threats.

Some reports have indicated that to meet stated force structure goals fully, the Air Force would need to buy roughly 100 F-35s and more than three dozen F-15EXs annually – far above current production levels and potentially pushing industry capacity to the limit.

And while it could be argued that spending must be reined in, it’s essential to consider the context underpinning all the decisions being made: China’s rapid military modernization.

The Pentagon’s annual China Military Power Report has shown just how much sustained growth the People’s Liberation Army continues to see in capabilities, spanning advances in fighter aircraft, missile systems, and integrated air defenses.

And while China’s defense budget remains lower on paper than that of the United States, its industrial base has been rapidly expanding production capacity for modern combat aircraft, iterating more quickly than that of the United States, and presenting a significant challenge for U.S. planners who must balance both quality and quantity of American assets.

Ultimately, the question may not be “can we afford it?” but “how can we afford it?”

Without continued U.S. development and significant investments in American infrastructure and industrial systems, the U.S. risks exposing itself to new vulnerabilities as China increases production tempo and narrows the technological-capability gap with the world’s most significant air force.

lol junk source, come with better source for your blabbering

lol junk source, come with better source for your blabbering

Like what source? US funds are largely tied down by its vast legacy weaponry system thus greatly hinders the development of its next generation weapons is a known fact.

and you haven't legacy weapons? in fact your PLAAF and PLAAN have 80-90% legacy weapons and copied designs from Soviet/Russa, same goes to Russia as well

Not a lot of them and since they are all crappy as you pointed out, China gets rid of them very fast and experiences little pain.

lol can i show the Numbers of legacy weapons In PLAAF/PLAN as compare to TOTALLY new weapons? why you have delusional dude that PLAAF has been reached qualitive and quantitive edge over USAF/USN lol

 

[Beijingwalker]

You can, and China builds new ships and planes very fast with sufficient funds and industrial capability, China doesn't suffer from funding constraint like US does.

 

[VCheng]

why you have delusional dude that PLAAF has been reached qualitive and quantitive edge over USAF/USN lol

Seriously, please encourage such delusions. We want us to be underestimated while they overestimate themselves.

don't include your civil shipbuilding industry you stupid, your military ship building rate is much lower than you expect, and your building because you're replacing you old junk Soviet copycat but you don't have unlimited $$$$ for defense, US defense budget is almost 4 times of Chinese national defense

That's what US always does to China, we never under estimate anyone.

LoL, Cursing gets you nowhere, we'll see.

Look at what's happening
Air mobilization... Elite US forces are pouring into Britain..It seems something unusual is happening today at the British "Fairford" base, where unprecedented military movements are being witnessed with the arrival of 10 massive cargo planes (C-17A) coming from the United States.

What's particularly intriguing is the source of these aircraft, as they are carrying elite forces from:

75th Ranger Regiment: Ranger (commando) forces.
101st Airborne Division: Known as the "Screaming Eagles".160th Special Operations Aviation Regiment (SOAR): Specialized in aerial support for covert and nighttime operations.

This concentrated buildup of special operations forces and paratroopers points to an imminent military operation or a high-level strategic maneuver on the European continent.
