Zelenskyy stated that more Patriot interceptors were used in three days of the Iran war than Ukraine received in three years. Reuters sources warned of imminent delays in Patriot supplies to Ukraine. Euromaidan Press calculated that Ukraine already lacked sufficient PAC-3 rounds to intercept 60 Russian Iskander ballistic missiles per month; the Iran conflict is draining a stockpile that was already inadequate.
The Iran war has created a zero-sum competition for a finite interceptor stockpile. Lockheed Martin produces roughly 600 PAC-3 rounds per year; current consumption rates across two simultaneous theatres exceed production by a wide margin. Ukraine's air defence against Russian ballistic missiles is degrading on a timeline of weeks, not months.
