Dutch authorities had said it was not clear whether they even had the power to intervene in the deliveries, part of a US-run operation that supplies parts to all F-35 partners.
Government lawyers also argued that if the Dutch did not supply the parts from the warehouse based in the Netherlands, Israel could easily procure them elsewhere.
The war was launched in response to the unprecedented attacks on Israel by Palestinian militant group Hamas on Oct 7.
Those attacks resulted in the deaths of around 1,160 people, mostly civilians, according to an AFP tally based on official Israeli figures.
Militants also seized about 250 hostages, according to an AFP tally based on official Israeli figures. Israel says around 130 are still in Gaza, though 29 are thought to be dead.
Israel has responded with a relentless offensive in Gaza that the territory’s Hamas-run health ministry says has killed at least 28,340 people as of Monday, mostly women and children.
International law experts have told AFP that human rights violations are likely being carried out by both parties to the conflict.
The International Court of Justice in The Hague, which rules on disputes between states, has said Israel must do everything possible to prevent genocidal acts in Gaza.
That ruling “strengthens our confidence in a positive ruling in our case”, said PAX Netherlands, one of the rights groups involved in the appeal.
