You’ve probably seen the headlines. One day the F-35 is a "trillion-dollar disaster," and the next, it’s supposedly cheaper than a Tesla—well, relatively speaking. It’s confusing. Honestly, if you try to nail down a single number for the f-35 cost per plane, you’re going to get five different answers from five different experts.
Why? Because "cost" is a slippery word in the world of stealth fighters. Are we talking about the sticker price for the jet alone? Does that include the engine? What about the software? Or the specialized helmet that costs more than a Ferrari?
As of early 2026, the math has shifted again. After years of prices trending downward, we’re seeing a bit of a rebound. It’s a mix of inflation, supply chain headaches, and the massive "Block 4" upgrades that are basically giving the plane a digital brain transplant.
The Current Price Tag: Breaking Down the Variants
Basically, there isn't just one F-35. There are three, and they don't cost the same. Lockheed Martin builds them on the same line in Fort Worth, but the internals vary wildly depending on whether the jet needs to land on a runway, a boat, or hover like a helicopter.
The F-35A: The "Budget" Stealth Jet
The A-variant is the one the Air Force flies. It’s the most common and, because of that, the cheapest. For the latest production lots (Lots 15-17), the "flyaway" cost—meaning the plane and its engine—sat around $82.5 million.
However, things are changing with Lot 18. New contracts with Pratt & Whitney for the F135 engine have seen engine prices jump to about $20.4 million each. When you add that to the airframe, the total price for a new F-35A is creeping back up toward $100 million per unit.
The F-35B: The Engineering Nightmare (in a good way)
This is the Marine Corps version. It can take off from short runways and land vertically. To do that, it has a massive Rolls-Royce lift fan behind the cockpit and a nozzle that swivels 90 degrees.

All that extra hardware makes it the priciest of the bunch. You’re looking at roughly $109 million per plane. It’s a marvel of engineering, but you pay for that complexity.
The F-35C: The Carrier King
The Navy's version has bigger, foldable wings and beefier landing gear to survive the "controlled crash" that is a carrier landing. It usually lands right in the middle of the price range, hovering around $102 million.
Why the F-35 Cost Per Plane is Rising Again
For a while, the narrative was that the F-35 was getting cheaper every year. Lockheed Martin even hit a goal of getting the A-model under $80 million. But then, reality hit.
Inflation isn't just a thing at the grocery store. It hits titanium, carbon fiber, and microchips too. Recent reports from the Government Accountability Office (GAO) and the Pentagon's Joint Program Office (JPO) highlight that raw material costs have spiked.
Then there’s the technology. We’re currently in the middle of "Technology Refresh 3" (TR-3) and moving toward "Block 4." Think of this like upgrading an old laptop to a high-end gaming rig. The new APG-85 radar and the advanced processing power required for modern electronic warfare aren't free.
The Pentagon actually slashed its F-35 order for the 2026 budget—cutting the Air Force's buy nearly in half. When you buy fewer planes, the price per plane goes up. It's the opposite of a bulk discount at Costco.
The "Sticker Price" vs. The Real Cost
If you buy a car for $30,000, that’s the price. But if that car costs $10,000 a year in gas and repairs, the "sticker price" is a lie.
The f-35 cost per plane is much higher if you look at the "System Unit Cost." This includes the simulators, the initial spare parts, and the specialized tools needed to fix the thing. When you bundle all that in, an F-35A is closer to $110 million, and an F-35B can soar past $135 million.
The Flight Hour Problem
This is where the real debate happens. It's one thing to buy the jet; it's another to fly it.
- F-35A: Roughly $33,000 to $36,000 per hour.
- F-16: Roughly $22,000 to $25,000 per hour.
The goal was always to get the F-35 down to $25,000 per hour by 2025. Honestly? It didn't happen. The jet is just too complex. The stealth coating needs constant attention, and the software—which has millions of lines of code—requires frequent patching and updates.
The $2 Trillion Lifetime Cost
You might have seen the "2 trillion dollar" figure floating around in news reports from 2024 and 2025. That number is staggering. It sounds like the plane is a black hole for money.
But context matters. That $2 trillion isn't what we've spent; it's what the U.S. expects to spend to buy, fly, and maintain the entire fleet through the year 2088.
Over 60+ years, $2 trillion averages out. Is it still a lot? Yes. But it’s not a one-time check the government just wrote. A huge chunk of that increase (about 44% more than previous estimates) comes from the fact that the military plans to keep the F-35 in service for 11 years longer than originally intended.
Comparing the F-35 to Other Jets
Is the F-35 expensive compared to its peers? It depends on who you ask.
The F-15EX, which is a heavily upgraded version of a 1970s design, actually costs about $90 million to $97 million per plane. That’s more expensive than the "base model" F-35A.
European competitors like the Eurofighter Typhoon or the Dassault Rafale often carry price tags north of $100 million for international buyers. Because the F-35 is being built in such massive quantities (over 1,000 delivered so far), it actually benefits from economies of scale that the Europeans can't match.
What This Means for You (and the Taxpayer)
Look, nobody likes seeing billions of dollars disappear into defense contracts. But the F-35 represents a shift in how we think about "value."
It’s not just a plane; it’s a flying sensor node. In a modern conflict, an F-35 might never fire a missile. It might just sit 50 miles away, invisible to radar, and tell every other plane and ship where the targets are.
Actionable Insights: How to Track the Real Numbers
If you want to keep an eye on where your money is going, don't just look at the total program cost. Watch these three indicators:
- Lot Definitization: Watch for when the JPO "definitizes" Lot 18 and 19. That’s when the final, non-negotiable price for the next few years is set in stone.
- Engine Core Upgrade (ECU): The F135 engine is being upgraded to handle more heat. This is a massive cost driver. If the ECU hits delays, the price per plane will spike.
- Availability Rates: If the planes are sitting in hangars because parts are too expensive, the "cost per flight hour" actually goes up because the fixed costs are spread over fewer missions.
The f-35 cost per plane isn't a static number you can find on a window sticker. It's a moving target influenced by global politics, labor strikes, and the sheer difficulty of making a 30-ton piece of metal invisible to the most advanced sensors on Earth.
Whether it's "worth it" is a question for the generals and politicians. But for the rest of us, understanding that an $80 million jet is actually a $400 million lifetime commitment is the first step in seeing the full picture.
To stay truly informed, you should regularly check the GAO’s annual "F-35 Sustainment" reports. They are dry, they are long, but they are the only place you'll find the unvarnished truth about where the money is actually going. You can also monitor the Department of Defense's "Selected Acquisition Reports" (SAR) which are usually released annually and provide the most detailed breakdown of unit costs available to the public.
