Europe’s Patriot Dilemma: Why Spain and Greece Are Holding Back Missiles for Ukraine

The proposed workarounds were deliberately pragmatic: Norway offered to purchase PAC-2 interceptors directly from Spain and Greece to donate them to Kyiv, while EU foreign policy chief Kaja Kallas argued that missiles approaching their technical expiration date should be deployed in Ukraine rather than decommissioned in Europe. Yet neither argument produced a commitment - a failure that comes at a dangerous moment, as Russian missile and drone attacks intensify alongside intelligence warnings of potential new offensive preparations toward Kyiv.

The missiles exist. The problem is who is willing to release them

Greece and Spain are not being asked to surrender an abstract military capability. They have operational reasons for keeping Patriot stocks.

Athens operates six Patriot batteries and has long regarded air defence as part of its deterrence posture against Turkey across the Aegean. Greece has supplied conventional ammunition to Ukraine since the early stages of Russia's full-scale invasion, but has consistently resisted transferring Patriot batteries or interceptors.

Spain faces a different political calculation. Madrid has pledged €1bn in bilateral military assistance to Ukraine for 2026 and transferred five PAC-2 missiles earlier this year. Yet it also maintains its own Patriot batteries and has stopped short of a wider commitment to its reserves.

The pressure from Brussels therefore collides with a basic feature of European defence policy: weapons are ultimately national assets. Governments must plan against threats that may never materialise, while Ukraine is consuming air-defence ammunition against a threat that is already firing every day.

That creates an uncomfortable asymmetry. A missile retained in a European arsenal preserves a theoretical capability against a future contingency. The same missile deployed in Ukraine can protect infrastructure and military forces against an immediate attack.

The fact that some PAC-2 stocks are approaching the end of their technical shelf life makes the impasse more difficult to justify operationally, but not necessarily easier to resolve politically.

A shortage created far beyond Europe

The Patriot problem cannot be solved simply by asking Washington for more missiles.

The United States has suffered severe depletion of its own air-defence reserves as a result of sustained military commitments in the Middle East associated with the Iran war. European allies have consequently begun exploring whether compatible Patriot munitions can be obtained from Asian operators, including Japan and South Korea.

This is a revealing change in the Western military supply chain. Ukraine is no longer drawing primarily on an expandable pool of Western stockpiles. Governments are searching for compatible missiles wherever they can find them, while new production struggles to catch up with wartime consumption.

That makes the distinction between existing inventory and industrial capacity increasingly important.

The older PAC-2 interceptor uses a blast-fragmentation warhead and remains effective against air-breathing targets and cruise missiles. PAC-3 MSE is a newer interceptor designed for direct kinetic interception and is operated by 16 of the 19 countries using Patriot systems globally.

Ukraine's immediate problem, however, is not simply access to the newest technology. It needs sufficient numbers of compatible interceptors for systems already integrated into its air-defence architecture.

This is where the European alternative becomes politically attractive but operationally complicated.

The SAMP/T argument is about more than air defence

France and Italy are pushing for the €90bn loan to Ukraine to favour European-made SAMP/T systems rather than Patriot equipment. SAMP/T, developed jointly by the two countries through the Eurosam/MBDA industrial partnership, is Europe's principal indigenous alternative to the US system.

There is a strategic logic behind that position. If European governments are now being forced to rebuild defence production, directing large-scale Ukrainian procurement towards European systems would create predictable demand for European manufacturers and reinforce the continent's ambition for greater strategic autonomy.

But Ukraine's battlefield requirement does not necessarily align with that industrial objective.

Patriot is already part of Ukraine's air-defence architecture. A further supply of PAC-2 interceptors therefore addresses an existing operational requirement. Introducing or expanding SAMP/T capacity can strengthen Europe's own industrial base, but it also creates logistical and operational challenges when compared with supplying additional ammunition for a system already in Ukrainian service.

The disagreement over the €90bn therefore represents two different definitions of urgency.

For countries focused primarily on Ukraine's immediate defensive capacity, Patriot is the practical answer because the infrastructure and operational experience already exist. For France and Italy, the financing mechanism offers something longer-lasting: an opportunity to turn European strategic autonomy from a political ambition into a procurement structure backed by major contracts.

The September 7 vote on the loan's procurement rules will expose how far those two objectives can coexist.

Europe is building for a war it cannot yet supply

The construction of the Patriot production facility at Schrobenhausen in Bavaria captures the deeper problem.

The facility, established by Raytheon and MBDA Deutschland through their COMLOG joint venture, is supported by Germany, the Netherlands, Romania, Spain and Sweden. It has secured contracts for up to 1,000 PAC-2 GEM-T missiles worth about $5.5bn. The first operational missiles are expected between late 2026 and 2027.

That is a significant industrial response. It is also too slow to resolve an immediate shortage.

A production line cannot retroactively replenish missiles being consumed today. The same contradiction is visible in Europe's search for third-country stocks and in the Norwegian proposal to purchase existing Spanish and Greek ammunition. Diplomacy is being used to bridge a gap that industrial policy will only begin to close later.

The shift is therefore from managing inventories to rebuilding them.

For decades after the Cold War, European militaries maintained forces and stockpiles calibrated largely to limited national requirements rather than sustained, high-intensity attrition. Ukraine has exposed the weakness of that model. Four years of intensive warfare, compounded by military commitments elsewhere, have turned air-defence interceptors into a scarce strategic commodity.

The result is a race between consumption and reconstruction.

The Norwegian workaround reveals the limits of European solidarity

Norway's proposed role is significant precisely because it is so unconventional.

Under the suggested arrangement, Norway would purchase PAC-2 missiles from Spain and Greece and subsequently donate them to Ukraine. In practical terms, the scheme attempts to separate the political act of transferring national military stocks from the final act of supporting Ukraine.

It does not eliminate the underlying sovereignty problem. Spain and Greece would still have to agree to sell the missiles, while the arrangement would need to satisfy the relevant national restrictions governing their transfer. But it offers governments a politically different route from making a direct bilateral donation.

Norway, meanwhile, would assume the role of financial intermediary and security broker.

That such a mechanism is being discussed at all is a measure of how constrained the conventional channels have become.

September 7 could turn an inventory crisis into a procurement crisis

The immediate danger for Kyiv is not that Europe lacks every possible air-defence solution. It is that the political system may prioritise the wrong timescale.

The €90bn loan could eventually strengthen Ukraine's air-defence capacity while simultaneously advancing Europe's industrial ambitions. But if procurement rules make access to US-made Patriot ammunition substantially harder, Ukraine could lose time at the point when time is precisely what its air-defence network lacks.

The Bavarian production facility illustrates why. Its first missiles are expected only from late 2026 into 2027, while Russia's intensified missile and drone campaign is a present-tense problem.

That leaves European governments balancing three competing clocks: the battlefield clock in Ukraine, the political clock of national security calculations in countries such as Greece and Spain, and the industrial clock required to rebuild Western missile production.

The diplomatic impasse in Wicklow exposed what happens when those clocks do not move together. Europe can identify missiles that may soon expire, propose mechanisms to buy them, promise billions for future procurement and build new factories - yet still struggle to put enough interceptors into Ukrainian launchers when they are needed.
