Ukraine's ability to intercept Russian ballistic missiles has fallen from more than 70% to zero this year as Patriot interceptor supplies run dry — a catastrophic failure that leaves critical infrastructure exposed to nightly Russian strikes. The shortage isn't a surprise. It's the predictable result of decades of NATO complacency, according to Jack Watling, senior research fellow for applied military sciences at the Royal United Services Institute, writing in The Guardian.
Vladimir Putin described Russia's latest generation of ballistic missiles as "Invincible" eight years ago. Four years ago, he unleashed that arsenal across Ukraine, hitting command centres, critical infrastructure and airfields. Ukraine received Patriot air defence systems from its international partners three years ago, and the US-supplied interceptor proved effective — until the missiles ran out.
The Industrial Mismatch
Countering ballistic missiles isn't simple or cheap. To intercept a tactical ballistic missile such as Russia's Iskander, a defensive system must track a target descending from the high atmosphere at more than five times the speed of sound while maneuvering unpredictably. The defensive system must communicate precise location data to the intercepting missile so it can adjust course while climbing against gravity. Building the radars, data links and interceptors for that task involves huge research and development investments, and across NATO most states have been happy for Washington to shoulder the burden over decades.
The US and licensed manufacturers in Germany and Japan produce about 840 Patriot interceptors a year. About 240 are older, larger PAC-2 interceptors, which climb close to the target and explode. The remaining 600 are PAC-3s, which are smaller and fly directly into the target. The latter approach is more effective but requires even more precise navigation, while the former can be used against other target types.
Russia produces about 750 Iskander missiles a year and is looking to increase production. Russia also uses air-launched Kinzhal ballistic missiles and repurposed air-defence missiles to conduct strikes, along with its arsenal of cruise missiles and drones. To have a high probability of success, it's generally recommended to fire two to three interceptors against each ballistic missile. When the launchers' limited coverage is factored in, and given that Ukraine is a vast country, Kyiv would ideally have three to four times the annual global production capacity of Patriot missiles to protect itself. Countries supporting Ukraine have therefore had to give their own stockpiles to Kyiv.
The Iran Shock
Even before the US decision to attack Iran, western allies were nervous about depleting their own stocks by giving Patriot missiles to Ukraine, knowing resupply would take years. The US attack on Iran, which prompted Tehran to fire ballistic missiles across the Middle East, created an acute global shortage. Where Russia usually fires fewer than 10 ballistic missiles in a single attack, Iran has launched upwards of 170 a day during the current and last year's war. A portion of Iran's missiles were also advanced, and in one instance it took 17 Patriot interceptors to defeat a missile. Iran has many more missiles in storage.
Ukraine won't receive enough Patriots between now and winter to save its critical national infrastructure, regardless of whether some countries make the political gesture of releasing a few more from their stockpiles. Kyiv must plan for a winter with severely disrupted power and disperse and fortify life-support systems such as water, sanitation, power and heating.
No Quick Fixes
Kyiv is trying to convince the US to activate Starlink satellite navigation modules over Russian territory to enable its drones to hunt for Russian missile launchers. As the US recently found in Iran, pulling off this kind of mission over a large area is extremely difficult. Another line of effort in Kyiv is to attack the production of Russia's ballistic missiles. Those factories are well defended and to succeed, Ukraine's partners will need to expand the funding and industrial capacity behind Ukraine's nascent cruise-missile industry, or reopen questions of providing weapons systems such as Germany's Taurus, which Berlin didn't provide to Ukraine for fear of military escalation.
The real lesson is that NATO members have abjectly failed in defence planning. The numbers in this equation have been known since at least four years ago and yet the investments to expand Patriot production, or mature alternative systems such as the Franco-Italian SAMP-T, haven't been made. That level of complacency is devastating for Ukraine today, but it also risks Europe being bereft of defences in the future. It remains remarkable that Europe, watching the consequences unfold on its very borders, has remained so idle.
Why This Matters:
This isn't just a story about Ukraine running out of missiles. It's about a collective security architecture that failed to match industrial capacity to strategic reality. NATO members knew the numbers before Russia's full-scale invasion — knew that global Patriot production couldn't sustain Ukraine's defense needs, let alone protect European cities if the war spreads. Yet no government mobilized industry to close the gap. The result is a winter of darkness for Ukrainian civilians and a Europe more vulnerable than at any point since the Cold War. The Franco-Italian SAMP-T remains underfunded. Germany still refuses to send Taurus missiles. The complacency Watling describes isn't an oversight — it's a political choice to defer hard decisions until crisis forces them. Ukraine is paying the price now. Europe may pay it next.
