Rising tensions with NATO over the U.S. stance on Ukraine and President Trump’s escalating commerce struggle now jeopardize a vital facet of the alliance’s airpower technique, as member international locations point out they might stroll away from plans to buy F-35 fighters.
The F-35 is at the moment operated by the U.S. and 19 allied nations — together with some non-NATO members similar to South Korea, Japan, Australia and Israel. However a number of NATO members are actually making ready to amass dozens of latest F-35 to exchange their getting older fleets that embody plane from the U.S., Europe and even Chilly Conflict-era Soviet-made fighters.
Nevertheless, on Thursday, Portugal’s protection minister pointed to “the recent U.S. stance in the context of NATO” as a think about rethinking the substitute of 28 F-16s with F-35 Lightning IIs. In the meantime, in certainly one of his first actions as prime minister, Canada’s Mark Carney referred to as for a evaluate of his nation’s resolution to buy a complete of 88 F-35s — a contract price greater than $13 billion. Germany’s order for 35 of the planes has additionally been thrown into query.
The idea of the Joint Strike Fighter (JSF) program, which ultimately turned the F-35, dates again a long time: the U.S. would lead growth of an plane for use throughout NATO. With air pressure, naval and marine variants, the aircraft would have superior stealth capabilities and cutting-edge sensors, radar and avionics that might carry out in air-to-air fight, ground-attack and reconnaissance roles. The F-35 has been affected by large price overruns and technical issues throughout growth. Finally, nevertheless, it has emerged as what some argue is the perfect fight plane on this planet.
“The F-35 is a really good plane that has best-in-class insurgency capabilities and low observability,” says Richard Aboulafia, managing director at Aerodynamic Advisory, an aerospace consultancy. If NATO abandons it, “that capability will be lost,” he says.
There are benefits for NATO to make use of the identical aircraft
The benefits for allies sharing the identical plane design embody a single communications platform, widespread “hardpoints” for carrying NATO munitions, the benefit of coaching pilots and upkeep crews, and the flexibility to share spare elements.
“It is easier to fight with allies when you use the same equipment,” says former Texas Rep. Mac Thornberry who was a key defender of the F-35 venture whereas in Congress. He says the actual significance of U.S. allies backing away from the F-35 “would be a further deterioration in the cohesiveness of NATO, which is what our adversaries would like to see.”
Lockheed Martin, the prime contractor for the F-35, mentioned in a press release to NPR that it values its robust partnership with the Canadian Air Power and Portuguese Air Power, however referred questions on overseas navy gross sales to the U.S. authorities.
For the international locations reconsidering the F-35, one attainable various is the Swedish-built Saab JAS-39 Gripen, a much less stealthy however quicker and longer-range plane that’s much less appropriate with NATO techniques. It has the extra benefits of being less expensive to purchase than the F-35, with decrease operational and upkeep prices.

Margaret Kosal, a former Protection Division official who’s an affiliate professor at Georgia Tech’s Sam Nunn College of Worldwide Affairs, views the sudden uneasiness over the F-35s as a symptom of rising mistrust inside the alliance since Trump took workplace.
“I see it as a potential canary in the coal mine, signaling a lack of confidence in the U.S.,” she says.
Concern of a “kill switch”
Amid the controversy, media retailers throughout Europe have expressed concern over a “kill switch” that could possibly be utilized by the U.S. to disable F-35s, whilst European protection officers have sought to quash the rumors. Earlier this month, Belgium’s chief of protection, Gen. Frederik Vansina, insisted that the F-35 “is not a remote-controlled aircraft,” whereas Switzerland’s division of protection mentioned such a tool shouldn’t be attainable.
Even when the “kill switch” is a delusion, the rumors possible present an absence of belief, Aboulafia says. “You know, there’s also the possibility that people are looking at this plane and saying, ‘Heck yeah, not only do we not want to give the U.S. money, but we’re also concerned about them cutting off support in the event of some kind of conflict.’ “
Given the view in Europe that Trump is abandoning NATO in favor of the Kremlin, in a hypothetical future battle with Russia, Europe would possibly fear that the U.S. may lower off spare elements and updates for the F-35, Aboulafia says.
In the meantime, the F-35 — which the Authorities Accountability Workplace initiatives will price the U.S. greater than $2 trillion all through this system’s lifespan — has additionally confronted rising criticism at dwelling.
On X, Elon Musk, whose effectivity group has been on the lookout for locations to chop federal authorities spending, has referred to as the F-35 an “expensive & complex jack of all trades, master of none” and posted a video of drone swarms, commenting, “Meanwhile, some idiots are still building manned fighter jets like the F-35.”
Aboulafia calls Musk’s assertion that the F-35 could possibly be simply changed by remotely piloted plane “a complete fantasy for so many different reasons,” stating that Musk “used, as an example, a fleet of short-range quadcopters that would make it about 30 miles before falling out of the sky.” Trump, prior to now, has additionally been crucial of the aircraft.
Washington Democratic Rep. Adam Smith, the rating member on the Home Armed Providers Committee, has additionally referred to as out the F-35 venture for price overruns. He says of the aircraft: “It’s like getting a quarterback in the NFL. You kind of got to have one, but you really hate to wind up overpaying for mediocrity.”
Even so, Smith says “it will make it harder if we’re looking for partners in a fight and they don’t have the same” platform.
The U.S. can be rethinking the F-35
Seth Jones, president of the protection and safety division of the Middle for Strategic and Worldwide Research (CSIS), acknowledges that “the U.S. itself is rethinking the purchase of F-35s” as a result of “questions about whether the future is really unmanned and autonomous platforms.”
Would NATO be capable to battle with out the benefits inherent in working a single kind of plane such because the F-35?
“It will have a negative impact,” Georgia Tech’s Kosal says. “But it won’t significantly degrade” capabilities.
Jones says the F-35 has “extraordinary capabilities” that might be tough or unattainable to duplicate in present plane.
“[It] has the ability to move inside of a Chinese or Russian anti-aircraft access denial bubble with stealth capabilities for both the collection of information, as well as to fire” both standard or nuclear munitions.
Nonetheless, he says, if NATO international locations are actually dedicated to spending extra on protection — one thing Trump has lengthy demanded — sourcing warplanes in Europe would possibly make extra sense to them. Jones factors to Portugal, which hasn’t but added any F-35s to its arsenal.
“If we start to see more of a European defense identity, particularly for Portugal, [it] may be a more logical decision … to pull something off of European production line, rather than have to resort to the U.S.”
