US Defense Secretary Pete Hegseth has not yet signed off on the transfer to Ukraine of at least some Patriot air defense interceptors held in the stockpiles of US allies, The Washington Post reported on Oct. 19. Kyiv needs the missiles to fend off Russian missile and drone attacks.
According to the newspaper, Hegseth has neither formally rejected the requests nor completed the steps needed to approve them, while continuing to approve other forms of assistance to Ukraine. Countries that buy US-made weapons generally need US government approval under their contracts before passing them on to a third country.
Kyiv suspects political pressure

Ukrainian President Volodymyr Zelenskyy said the shipments are awaiting Hegseth's final signature. Ukrainian officials told the Kyiv Independent they suspect the delay may be a form of political pressure on Kyiv.
NATO said deliveries under the PURL mechanism, including air defense equipment, are continuing. Another alliance spokesperson said some shipments may be delayed but that political reasons are unlikely.
According to some media reports, the delay comes as the Trump administration pursues a broad deal with Russia and scales back support for Ukraine to press it toward ending the war.
