What the Iran War Reveals About Europe’s Air Defence Gap

Europe diagnosed the problem correctly — but prescribed a three-year treatment for a condition that can become acute overnight.

Institute for Central Europe — Policy Mini Brief | 8 March 2026

Executive Summary

The US-Israeli war on Iran (Operation Epic Fury, launched 28 February 2026) has consumed hundreds of high-value air defence interceptors in under a week, with at least one Gulf ally already requesting emergency resupply.

Production of replacement missiles will take over a year at current capacity. European NATO allies — especially Central European states on the eastern flank — depend on the same constrained US production pipeline for their own deterrence.

Europe has correctly identified Ukraine’s battle-proven counter-drone model as the solution to the cost asymmetry between cheap attack drones and expensive interceptors, and has launched multiple institutional initiatives to adopt it.

But implementation timelines stretch to 2027–2030 — while the Iran war has just demonstrated that magazine depth crises unfold in 96 hours. The timeline is the vulnerability.

 

The Interceptor Crisis in Real Time

On 28 February 2026, the United States and Israel launched Operation Epic Fury — a joint campaign targeting Iran’s nuclear infrastructure, missile production, naval forces, and proxy networks. Within 36 hours, Tehran retaliated with hundreds of ballistic missiles and one-way attack drones targeting not only Israel but also US military installations and civilian infrastructure across Bahrain, Kuwait, Qatar, the UAE, Saudi Arabia, Jordan, and Iraq.

As Sinem Cengiz of Qatar University’s Gulf Studies Center noted, for the first time in history all Gulf Cooperation Council (GCC) states were targeted by the same actor within 24 hours — “their long-standing nightmare scenario” (Breaking Defense).

A week into the conflict, the defence economics has been already unsustainable. Iran’s Shahed-136 drones cost approximately $20,000 each. Each Patriot PAC-3 interceptor used to shoot them down costs between $3.7 and $4 million (Japan Times). At least one Gulf ally has requested emergency interceptor resupply from Washington after its stockpiles ran critically low within 96 hours of fighting (CNN).

The Pentagon acknowledged in a closed-door congressional briefing on 4 March that Shahed drones represent a major challenge and that US air defences will not be able to intercept them all (The War Zone, CNN).

The production math is punishing. Lockheed Martin produced 620 PAC-3 MSE missiles in all of 2025. An estimated 800 or more interceptors may have been expended in the first days of this war alone, according to Defence Express calculations — potentially requiring over 15 months of uninterrupted production to replace at current capacity. THAAD interceptors, critical against Iran’s most capable ballistic missiles, are in even shorter supply. Planned production increases to 2,000 PAC-3 missiles per year remain years from realisation (Defense Express/United24, Defense Security Monitor).

Iran’s strategy is deliberate. By launching mixed salvos — cheap drones as screening assets alongside ballistic missiles as the lethal punch — Tehran collapses the defender’s ability to match the right interceptor to the right threat. In compressed engagement windows, sensor uncertainty and saturation make reliable discrimination between a $20,000 Shahed and a cruise missile operationally difficult, and the consequences of a single leak through the defensive layer are catastrophic enough that expensive interceptors get burned regardless.

Retired Lt. Gen. Dan Karbler, former commander of US Space and Missile Defense Command, acknowledged that short-range air defence assets are needed precisely to avoid expending scarce Patriot missiles on drones (ABC News).

The resulting cost-exchange ratio — running from 14:1 to more than 100:1 in the attacker’s favour — is not a battlefield anomaly. It is a strategy of systemic attrition aimed at the adversary’s industrial base (Washington Times).

 

Europe’s Exposure

The Iran war is unfolding in the Middle East, but its consequences cascade directly into European security. Every Patriot round fired over Abu Dhabi is one fewer round available for NATO’s eastern flank. Every THAAD interceptor consumed in the Gulf degrades the stockpile that was meant to underwrite extended deterrence from the Baltic to the Black Sea.

The US defence industrial base does not maintain separate production lines for separate theatres — it runs a single, constrained pipeline that now faces competing demands from an active war, ongoing Houthi interdiction operations, and the standing requirements of European and Indo-Pacific deterrence (Defense Security Monitor).

European NATO allies enter this moment from a position of pre-existing weakness. Stockpiles have been significantly drawn down by donations to Ukraine since 2022. Replenishment has been slow.

On 17 February — eleven days before the Iran war began — German Foreign Minister Johann Wadephul stated bluntly that Berlin has exhausted its own air defence missile stocks: “We simply don’t have any left” (Euromaidan Press).

National procurement timelines remain measured in years (CNBC). If Europe’s largest economy and defence spender has already emptied its reserves before the Iran war even started, the position of smaller Central European states is self-evidently worse.

Central European states — Slovakia, the Baltic states, Romania, Poland — are the most exposed: closest to the Russian threat, thinnest in organic air defence capacity, and most dependent on US-sourced systems and munitions that are now being consumed at wartime rates in a theatre 3,000 kilometres away.

The war has already demonstrated that the threat is not geographically contained. On 4 March, NATO air and missile defence assets in the eastern Mediterranean intercepted an Iranian ballistic missile heading toward Turkish airspace — the first time the alliance has defended a member state from an Iranian projectile since the conflict began (Bloomberg, France 24).

Earlier, on 2 March, a Shahed-type drone struck RAF Akrotiri in Cyprus — a British sovereign base on EU member territory — in what Cypriot officials confirmed was a Hezbollah attack launched from Lebanon, not from Iran directly (TIME, Middle East Eye). Two additional drones heading toward the base were intercepted the same day. Azerbaijan reported Iranian drone strikes injuring civilians (CNBC). NATO’s Aegis Ashore sites in Romania and Poland — systems originally developed with an Iranian ballistic missile threat in mind — are now on full alert (Stars and Stripes).

The proxy dimension makes the threat harder, not easier, to defend against. Destroying Iranian launchers does not neutralise a dispersed network of militia launch sites across the Levant.

Analysis of the Akrotiri wreckage revealed a Russian-made Kometa-M anti-jamming GNSS receiver — identical to components found in Russian drones and missiles used against Ukraine — indicating that Iran’s drone fleet now carries electronic countermeasures that render simple GPS jamming ineffective (Ukrainska Pravda, United24).

The Kometa-M finding also confirms an operational reality Central European defence planners cannot ignore. The same Russian-Iranian technology chain that targets Ukraine and the Gulf can reach European territory through proxy networks — and Moscow’s calculus on its own western flank may shift as it observes US interceptor stockpiles being consumed thousands of kilometres away.

 

None of this is wrong. But all of it is too slow.

Europe has correctly identified both the problem and the direction of the solution. Ukraine’s four-year experience of defending against massed Russian drone attacks produced a body of operational knowledge that is directly transferable: low-cost FPV interceptor drones that destroy drones at a fraction of the cost of a missile; decentralised mobile teams combining electronic warfare with kinetic intercept; compressed innovation cycles that adapt to new threats in weeks rather than years.

European states are already adopting Ukrainian-proven systems and tactics in counter-drone warfare, electronic warfare integration, and long-range strike methods (Jamestown Foundation).

A caveat: the Kometa-M finding at Akrotiri confirms that even “cheap” drones now carry frequency-agile anti-jamming systems, meaning that effective counter-drone defence will require more sophisticated electronic warfare capabilities than basic GPS jamming alone. Far from weakening the case for learning from Ukraine, this makes it more urgent: Kyiv has been adapting its EW tactics to Russian countermeasures in real time for four years.

European institutions have recognised this. On 11 February, the European Commission published its Action Plan on Drone and Counter-Drone Security, explicitly referencing a Drone Alliance with Ukraine (European Commission).

On 20 February, the E5 nations — France, Poland, Germany, the United Kingdom, and Italy — announced a joint programme to produce low-cost air defence systems and autonomous drones using Ukrainian expertise (AP/PBS). The European Drone Defence Initiative, the Eastern Flank Watch, and the European Air Shield are all moving through institutional channels (European Policy Centre). The analytical logic is sound: build a cheap lower layer to handle drone threats so that expensive conventional interceptors — Patriot, SAMP/T, IRIS-T SLM — are preserved for the ballistic and cruise missile threats that only they can defeat.

The European Drone Defence Initiative targets first operational capabilities by end of 2026 and full functionality in 2027. The broader Defence Readiness Roadmap stretches to 2030. The E5 programme has pledged to cover the investments (Dronelife, AP/PBS).

These timelines were designed under the assumption that Europe would have years of uninterrupted time window to implement its adaptation. The Iran war has just demonstrated that magazine depth crises unfold in four days. That is not a planning assumption, it is already an observed and confirmed fact. The European implementation timeline and the threat timeline are mismatched by orders of magnitude.

The September 2025 incursion of Russian Gerbera one-way attack drones into Polish airspace already illustrated the cost asymmetry: multi-million-dollar Patriot missiles and F-35s were used to intercept drones worth no more than $10,000 each (European Leadership Network). That incident was a warning. The Iran war is the proof.

 

Closing the Gap

The challenge is not conceptual. Europe knows what needs to be built. The challenge is tempo — and tempo cannot be solved by committee. Three immediate steps would narrow the gap between strategy and operational reality.

First, accelerate procurement of fielded Ukrainian counter-drone systems and solutions through emergency acquisition pathways, bypassing standard EU and national procurement cycles. Ukraine is already exporting operational knowledge to Gulf states at British invitation. Central European allies should be first in line, not last. Poland’s existing bilateral drone cooperation with Ukraine provides a template. Slovakia, Romania, and the Baltic states should replicate it immediately.

Second, reframe European counter-drone investment as interceptor conservation, not as a separate capability track. A $4 million interceptor is justified when it prevents a $4 billion catastrophe. But the calculus collapses when finite stocks are depleted on threats that could have been neutralised at a fraction of the cost. Every euro spent on a system that can destroy a $20,000 drone without expending a $4 million missile is a saving that keeps scarce conventional interceptors available for the threats only they can defeat. This reframing matters for political buy-in: it ties cheap drone defence directly to the credibility of NATO’s conventional deterrence posture.

Third, treat the Iran war as the stress test it is and publish honest assessments of national magazine depth. European allies have avoided transparent accounting of interceptor stockpiles for understandable reasons of operational security. But the political urgency required to override procurement inertia depends on democratic publics and parliaments understanding the scale of the gap. If a Gulf states can exhaust their interceptor supply in four days of fighting, European leaders must answer how long their own stocks would last under comparable conditions — and what they intend to do about it before 2027.

 

Conclusion

The Iran war did not create Europe’s air defence vulnerability. It revealed it on an accelerated timeline. Europe diagnosed the problem correctly, identified Ukraine’s experience as the most relevant operational model, and launched institutional initiatives that point in the right direction. But the pace of implementation assumed the time.

That assumption is now empirically proved incorrect. The interceptor stockpiles that European security depends upon are being consumed in real time in a theatre Europe does not control and cannot resupply.

The cheap, adaptive counter-drone layer that would mitigate this dependency exists as a proven concept but not yet as a fielded European capability. The timeline is the vulnerability. The question is no longer what to build, but whether Europe can build it before it needs it.
