European countries are struggling to provide Ukraine with enough Patriot interceptors as Kyiv prepares for an expected Russian winter assault, with US supplies strained and new production unlikely to arrive before the attacks begin, Politico reported.According to Politico on Tuesday, Ukraine is seeking hundreds of interceptors for its ballistic missile defenses, but several of its leading European supporters say they have limited stocks available, while also needing to protect their own territory and meet NATO commitments.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official.“We are literally fighting for every missile,” Ukrainian Foreign Minister Andrii Sybiha said.Ukraine relies heavily on US-made Patriot systems to intercept Russian ballistic missiles, one of the few weapons in its arsenal capable of countering the threat.In July, Ukrainian air defenses intercepted just 29 of 195 Russian ballistic missiles, while another 40 reportedly failed to reach their targets, according to Ukraine’s defense ministry.Former Ukrainian Defense Minister Mykhailo Fedorov said Russia was firing more missiles at Ukraine each week than its partners were providing over several months.Ukraine is also developing the domestically produced Freyja interceptor, but the system still requires investment, engineering work, and testing before it can provide a significant alternative to Patriot.Most PAC-3 Patriot interceptors are manufactured in the US, making Washington central to Ukraine’s efforts to replenish its stocks.
