The countries recently signed a resource deal linking continued American aid to access to Ukrainian minerals

The US has approved a $310.5 million deal to sustain Ukrainian-operated F-16 fighter jets provided by Kiev's European backers. The move comes after the US and Ukraine signed a deal in which Kiev grants Washington access to its natural resources in exchange for future assistance.

The F-16 deliveries from European NATO members to Ukraine were approved by former US President Joe Biden in August 2023, but the first jets did not arrive in the country until a year later. While Ukrainian officials hailed the deliveries as a major coup, Western media warned that they would not be a "game changer" in the conflict. In March, the Ukrainian Air Force acknowledged that the F-16s operated by Kiev "cannot compete" with the latest Russian jets.

In a statement on Friday, the Pentagon's Defense Security Cooperation Agency (DSCA) said the State Department had signed off on a foreign military sale to Ukraine which includes training, spare parts, aircraft modifications, logistics assistance, and software support for F-16s.

The agency added that the proposed sale "will support the foreign policy goals... of the United States by improving the security of a partner country that is a force for political stability" in Europe.

More than 80 F-16s have been promised to Ukraine, with the bulk expected to come from Belgium and the Netherlands, while the US has never committed to providing the jets on its own. While the exact number of jets delivered is unknown, Moscow confirmed last month it had shot down one F-16. Ukraine's Vladimir Zelensky said the aircraft's pilot perished during a "combat mission."

In 2024, Ukraine reported the loss of another F-16, saying it crashed while repelling a Russian air strike.

The DSCA announcement comes after the Pentagon said it is sending "disused and completely non-operational F-16s to Ukraine for parts." It also follows the signing of a US-Ukraine resource deal that is intended to allow Washington to recover the cost of future military support through shared proceeds from Ukrainian mineral resource licenses.

Moscow has condemned the Western arms shipments to Ukraine, warning they will only prolong the conflict without changing the outcome. Russian President Vladimir Putin has said Ukrainian-operated F-16s will "burn" just like other Western-supplied equipment.
