A critical shortage of interceptor missiles has left Ukrainian Patriot air defence launchers empty, failing to stop recent Russian ballistic missile strikes on Kyiv and threatening to erode military momentum ahead of winter.
The Financial Times reported that the Ukrainian Air Force stopped publishing data on the number of missiles Russia launches to avoid revealing how many escape interception. Sources cited by the newspaper said the decision was taken for operational security and to maintain public morale.
The air defence deficit follows a summer campaign of long-range Ukrainian strikes against Russian energy infrastructure. Those attacks triggered Russia's most severe fuel crisis since the collapse of the Soviet Union in 1991, placing Kyiv in one of its strongest strategic positions since the 2022 invasion.
US stockpile concerns
Fears are growing in Kyiv that those gains could be undone as Moscow intensifies its missile campaign. US caution regarding escalation and the depletion of allied stockpiles have left Ukrainian cities vulnerable. Ukrainian President Volodymyr Zelenskyy estimates that his country requires at least 300 interceptor missiles from partners in the United States and Europe to get through the winter.
According to sources familiar with negotiations, US President Donald Trump did not agree to supply additional Patriot surface-to-air missile batteries for the coming months during a White House meeting with Zelenskyy in late July. Kyiv remains hopeful of securing shipments of additional interceptor missiles from Washington, but official approval has not been granted.
Alternative air defence measures
Ukraine first received Patriot missile systems, developed in the United States as surface-to-air defence batteries capable of tracking and intercepting high-speed ballistic missiles, from international allies in 2023. They represent one of the few defence systems in Ukraine capable of intercepting Russian ballistic projectiles.
To offset the missile shortage, Ukraine is exploring strategies to degrade Russia's strike capacity at the source. Ukrainian forces are considering targeting industrial plants that produce ballistic missiles, alongside expanding domestic manufacturing of long-range weapons.
European support and missile targets
Supplies could also arrive from Poland, where decision-makers are expected to approve the transfer of an additional batch of interceptor missiles shortly. Warsaw's position was influenced by a recent incident in which a Russian missile violated Polish airspace.
Zelenskyy has urged Washington to allocate a fraction of its existing stocks, stating that Ukraine requires at least 5% of the US reserve of Patriot interceptor missiles to survive the winter. He added that obtaining 10% of American stockpiles would allow Ukrainian air defence forces to destroy all incoming Russian ballistic missiles.
