The notification was published on 30 October. The package includes classified and unclassified spare parts as well as logistics and software support, with Lockheed Martin as the principal contractor.
The State Department said the sale would not require the deployment of additional US government or contractor representatives to Ukraine and would not affect the readiness of the US armed forces.
No US budget funds are involved. According to the State Department, Kyiv will pay for the purchase through donations from Canada, Germany and Norway under the JUMPSTART programme, as well as national funds financed under the EU's Ukraine Support Loan. The White House administration has notified Congress; lawmakers have 30 days to make a final decision. The notification did not specify when deliveries could begin.
The State Department said the sale "will improve Ukraine's ability to counter current and future threats" and would allow existing Patriot systems to keep operating.
Ukraine has spoken of a shortage of Patriot missiles for several months. In a speech in Brussels on 15 October, President Volodymyr Zelensky confirmed a "significant deficit" of interceptors and called it "no secret", since Ukraine is not a priority destination for supplies of these missiles. According to him, the country receives on average only 12 Patriot missiles a month.
On 15 October CNN, citing a source, reported that Ukraine had completely exhausted its stock of missiles for Patriot systems. The channel's source said that because of the lack of interceptors, almost all Russian ballistic missiles during the latest mass strike could not be shot down. On the night of 14 October, Russian missiles hit three power plants in Kyiv and energy facilities in Kharkiv; four people died in the capital and another 25 were injured.
Earlier this week, Zelensky said on his Telegram channel that Kyiv had been waiting almost a month for the signature of US Defense Secretary Pete Hegseth to receive missiles for Patriot and NASAMS systems. He instructed Ukrainian officials to discuss the issue again with the American side and reported talks with partners that hold stocks of PAC-2 and PAC-3 missiles.
