Legal battles loom over supply chain keeping Israeli F-35s flying over Gaza and Lebanon
A slew of court cases around the world are raising questions about the legality and transparency of the international supply chain that helps keep Israeli F-35 fighter jets flying over Gaza and Lebanon.
Israel has used the F-35, described by its American manufacturer Lockheed Martin as "the most lethal" fighter jet in the world, extensively in its nearly year-long offensive in Gaza, in which over 41,000 people have been killed.
Best known for its stealth capabilities, the F-35’s use in Gaza, an enclave without an air force where less sophisticated F-16s and F-15s are perfectly capable of dropping bombs, may seem out of place.
However, arms control experts and researchers say Israel has had to rely on F-35s to maintain the high volume of strikes conducted over the past year in Gaza and now in Lebanon, where weeks of bombings have killed more than 1,000 and displaced over 1.2 million.
"They need all of their planes to participate," said Noam Perry, strategic research coordinator for the American Friends Service Committee’s (AFSC) Action Center for Corporate Accountability.

Israel has been aided by surges in the flow of F-35 parts from the United States, which experts say have been crucial in keeping the planes airborne.
Litigation in the Netherlands has already stopped the transfer of spare parts stored at one of three global F-35 distribution hubs to Israel since February.
As four cases against arms exports to Israel move forward, governments in the UK, the Netherlands, Canada and Denmark face difficult legal questions regarding F-35 parts made in their countries.
Middle East Eye also understands that NGOs that took Australia to court over arms exports to Israel in a case that was discontinued last year remain determined to find ways to hold the government accountable for F-35 parts manufactured there.
A key question posed by these cases is how the governments can continue to license the export of F-35 parts bound for Israel while complying with domestic laws and international treaties, which require them to assess whether such parts could have been, or will be, used in violation of international humanitarian law.
So far, the response in at least three of the countries - the Netherlands, the UK and Canada - is that F-35 parts sent to third countries, but ultimately destined for Israel, can be treated differently than weapons that go directly to Israel.
One rationale provided by the UK and Dutch governments is that suspending parts whose final destination is Israel would disrupt the global supply chain, as the parts are difficult, if not impossible, to trace.
Last year, the US Government Accountability Office (US GAO) found that over $85m worth of spare F-35 parts had been lost globally because the US government and private contractors had not determined who was responsible for tracking them.
However, arms control experts and litigants who spoke with MEE say this is clearly a case of politics, not logistics.
“They can track these things within very small areas, in real time, everywhere in the world,” said Martin Butcher, policy advisor on arms and conflict for Oxfam, which is involved in a legal challenge against UK arms exports to Israel being brought to the High Court.
“The idea that they can’t track them is absolute nonsense.”
Parts moved 'at breakneck speed'
While experts say it is difficult to establish which type of aircraft Israel has used in specific attacks over the past year, it is clear that F-35s have played a key role in Israel’s air war on Gaza and now Lebanon.
Much of what is known comes from Israeli media reports or other public sources, including a post on Israeli Defence Minister Yoav Gallant's X account. This post was utilised by the Danish news outlet Information and NGO Danwatch to confirm that an F-35 had been used in a designated safe zone in Gaza in July that killed at least 90 people.
However, there are other signs that the F-35 has been crucial.
Chairing a hearing before the US House Subcommittee on Tactical Air and Land Forces in December, Representative Rob Wittman said the F-35 programme had “moved at a breakneck speed” to deliver more spare parts to Israel.

Last year, British companies used open licences covering the F-35 programme 14 times to export items directly to Israel, nearly three times more than in each of the two previous years, according to data obtained by the UK-based Campaign Against the Arms Trade (Caat).
It is unclear when the shipments were sent in 2023, but Caat believes the jump likely indicates a heightened demand from Israel for spare parts since 7 October.
While bombs are often the focus of arms embargo campaigns, spare parts for the F-35 - and other fighter jets in Israel's fleet - have been critical to Israel's air war in a way that is frequently overlooked by the public, said Josh Paul, a former State Department official who resigned in protest last October.
"Modern fighter jets rely on immense amounts of continuous maintenance," said Paul, who is now a fellow at the US-based NGO Democracy for the Arab World Now (Dawn).
He estimated that for every one hour of flying, a fighter jet requires three hours of maintenance.
"If you cut off the supply of spare parts, particularly on something like the F-35s, which relies on a global just-in-time delivery chain, it would very quickly become unflyable."
Flying F-35s in seemingly unnecessary conditions over Gaza may have been useful for the Israeli Air Force to maintain fleet readiness and gain insights into the fighter jet's capabilities in combat.
That information will also have been relayed back to the prime contractor, Lockheed Martin, the US Air Force and potentially other partner countries in the F-35 programme, several arms experts told MEE.
Lieutenant-General Michael Schmidt, who oversees the F-35 programme, said in December that Israeli F-35 users were “achieving exceptional mission capability rates and the aircraft is proving resilient”.
“We’re learning a tremendous amount and will apply lessons learnt to enhance fleet readiness across the globe,” he told the House Armed Services subcommittee.
“A lot of militaries are benefiting from what Israel is doing right now," said Perry of the AFSC.
"All of the air forces that have F-35s, that have ordered F-35s or that have considered ordering them, they are all benefitting from this - and, of course, Lockheed Martin itself.”
A programme like no other
The information sharing among F-35 partners is just one example of a global defence programme that operates like no other.
The consortium is managed by the Pentagon’s F-35 Joint Program Office (JPO) and includes seven allied countries that have contributed varying amounts to the programme's research and development in exchange for price reductions on fighter jet purchases.
Seven other countries that are not partners in the programme have also purchased the F-35, including Israel.
Lockheed Martin says the F-35 supply chain involves more than 1,900 companies in the US and in the countries that have acquired the aircraft.
Arms control experts told MEE that the F-35 is run on a “just-in-time” delivery system, allowing the fighter jet to send a message to alert its operators when a new part will soon be needed.
“Then the base requests from the depot - whatever depot it is in, be it in the Netherlands or Japan - and says we need this bit,” said Oxfam’s Butcher. “It’s all tagged electronically.”
This is why many, including Butcher, are sceptical when governments say they cannot suspend F-35 components destined for Israel due to the difficulty of tracking them across a complex, multinational supply chain.
Gerard Jonkman, director of the Rights Forum, one of three Dutch NGOs challenging their government over arms exports to Israel, told MEE: “Even Ikea or any company in the world knows exactly where their spare parts are coming from. So what about a plane like this?
'If your logistical system is not able to cope with international law, then you have to find a way to change your logistical system'
- Gerard Jonkman, The Rights Forum director
“If one batch at a certain moment would turn out to be of bad quality, then you would need to know from where they are coming and in which planes they have been assembled.”
Even if it is true that it is currently impossible to trace F-35 parts, this should be addressed, he said.
“If your logistical system is not able to cope with international law, then you have to find a way to change your logistical system,” Jonkman said.
When asked if components from partner countries could be tracked and traced, Lockheed Martin directed MEE to the US government.
F-35 JPO spokesperson Russell Goemaere told MEE in a statement that maintaining accountability for parts and data is "essential to ensure prudent management of F-35 financial and operational resources".
"However, most F-35 parts are part of a global spares pool procured for the benefit of all F-35 customers. Parts in this global pool are not designated for any designated end user as they are procured and are instead issued and distributed to our customers based on demand and prioritization, when needed," Goemaere said.
"While the F-35 supply chain is capable of controlling material movement based on part number/configuration, no current system, process or business rule is in place to filter out or stop the movement of specific serial numbered material to any specific country based on its country of origin."
Political problem
More than just a logistical problem, those challenging governments to stop the export of F-35 parts to third countries believe their governments feel locked into the US-run programme.
“The US is the government that has taken and demanded complete control over the F-35 programme, including which country can even buy it,” said Frank Slijper, leader of the arms trade project at PAX, the Dutch NGO involved in the legal challenge there.
'They clearly have no interest in countries like the Netherlands or the UK messing up what is so central to American foreign policy'
- Frank Slijper, PAX project leader
“They clearly have no interest in countries like the Netherlands or the UK messing up what is so central to American foreign policy.”
They also believe their governments may fear that if they suspend parts, they will be seen as unreliable partners in any future defence programmes. No partner country in the F-35 programme, touted in promotional videos as “diplomacy in action”, is understood to have ever suspended parts.
Partner countries may also worry about the legal consequences of companies manufacturing and exporting F-35 parts if they suspend licences to third countries.
On the other hand, they point out that, unlike the United States, all the countries where litigation is currently underway are parties to the Arms Trade Treaty.
Under the treaty, arms transfers are prohibited when it is more likely than not that they will be used to commit certain human rights violations.
“If they would not act on this specific case of F-35s and Israel, they lose their credibility,” Slijper said.
“Subcontracting companies and countries indeed have a responsibility and they cannot leave it to another state - in this case, the US - that is not part of the Arms Trade Treaty.”
Jonas Devantier, the programme advisor for Oxfam Denmark, one of several NGOs challenging the Danish government, said that during their legal case, he and others learned that roughly 90 percent of the arms exports Denmark provides to Israel are through the F-35 programme.
One component made in Denmark is a pylon that releases bombs from the fighter jet. “So it is very clear that it is needed for the F-35 to be used in the way that they are,” Devantier said.
In March, the Danish government announced it was implementing “a very restrictive approach” to arms exports to Israel, which turned out to be restrictions on new export licences.
Existing licences, including those covering exports related to F-35s, remain in place.
Devantier said: "It has become more and more untenable to maintain that the F-35 fighters cannot or should not be subject to the same scrutiny as the other exports."
Hearings in most of the court cases are scheduled to be held in the coming weeks.
