Summary and Key Points: The F-35 Joint Strike Fighter program carries a staggering $2 trillion price tag, but expert Harrison Kass argues this figure is misleading without context.
-This cost covers the entire “ecosystem” of the aircraft—including development, fuel, and maintenance—across a projected service life extending into the 2070s or 2080s.
-Much like the B-52, which is expected to fly for a century, the F-35’s longevity disperses these costs over decades.
-By consolidating multiple roles and replacing older jets like the F-16 and F/A-18, the F-35 provides a unified, albeit expensive, global fleet for the U.S. and its allies.
The $2 Trillion Jet: Why the F-35’s Shocking Price Tag Is Actually a Bargain
Some describe the F-35 Joint Strike Fighter (JSF) as a $2 trillion aircraft. That number refers to the program’s lifetime cost, obviously not the unit costs. Two trillion sounds outrageous, and arguably is, but the F-35 is expected to remain in service into the 2070s or 2080s, dispersing the program costs across decades, making the price tag more palatable.
How long will the F-35 actually fly?
The JSF entered service in the mid-2010s, with a service life expected to extend until at least 2070. With upgrades, the hope is that the F-35 will remain in service beyond 2070. That timeline mirrors the F-16, which debuted in the 1970s, but is still being produced and exported today, and the B-52, which debuted in the 1950s but is expected to serve until the 2050s, a full one hundred years.
It has transitioned into a design philosophy where fighter jets are long-term platforms, not the short-lived projects that were so common in the early Cold War. A 60-year lifecycle is no longer unusual. And once that timeline is understood, the cost figure becomes less shocking.
What does $2 trillion get you?
The headline number includes research and development, procurement, operations, and sustainment. So it’s a comprehensive price tag.
The rough breakdown includes $400 billion for development and acquisition, with $1.3-1.5 trillion for sustainment, which becomes the primary cost because thousands of aircraft are flying, accumulating decades and decades of flight time.
Flying a military aircraft is expensive, of course, requiring fuel, parts, software, maintenance, personnel, and training. So the $2 trillion figure is not just for a single aircraft but for the entire enterprise of operating it across decades.
Fifth-generation sustainment
The real cost is sustainment.
Flying a stealth fighter is especially expensive. The F-35 required specialized coatings, advanced diagnostics, software-heavy maintenance, etc. These require specialized tools and highly trained maintenance crews.
Every flight hour generates long-tail costs—which is why, over decades, sustainment dwarfs procurement costs. This is not unique to the F-35, however. The difference is that the F-35 flies everywhere, all the time. Ironically, the more successful the aircraft, the higher its lifetime cost tends to be; popularity increases total costs, not inefficiency.
Scaling up
The F-35 program, to date, includes nearly 3,000 aircraft, operated by the US Air Force, US Navy, US Marine Corps, and over a dozen allied nations. The JSF serves to replace the F-16, F/A-18, AV-8B, and A-10 (partially), thereby saving costs through role consolidation, at least in theory.

Instead of multiple programs, the F-35 will form a single global fleet. So the cost reflects centralization and standardization efforts not just within the US but within the wider NATO and Western-aligned coalition of countries. The F-35 is not about one jet but an entire ecosystem.
Hard to compare
Critics often compare the JSF to older aircraft like the F-16 and F/A-18, which were cheaper programs.
The F-16 and the F/A-18 benefited from operating in simpler times, allowing simpler platforms that could compete in less contested environments. Modern threats have changed, demanding greater stealth, sensor fusion, and networked warfare.
The argument follows that the alternative isn’t a cheaper F-35 but a variety of unconsolidated specialized aircraft, which would likely cost more in the aggregate.
Is the cost worth it?
Justifying the F-35’s cost depends on your priorities. The F-35 provides a wide range of capabilities from air dominance to strike to ISR to electronic warfare, all in one platform. Without the F-35, the US would arguably need more aircraft types, more training pipelines, and more logistics chains—which would be more expensive. So, the question becomes whether you believe the US needs the capabilities offered by the JSF.
If yes, then the F-35 is arguably an affordable trade-off. If not, then the F-35 may feel superfluous. Regardless, cost efficiency in the F-35 stems from its ability to replace other programs through role consolidation, not necessarily from the aircraft itself.
If the JSF serves for 60 years or more and effectively replaces other platforms, then the $2 trillion price tag becomes more reasonable. The F-35 was designed for longevity and adaptability, and the cost reflects how long the aircraft will be central to US air power.
