Everyone Needs an Israeli Style Iron Dome: A Global Scramble for Missile Defense

The rush is staggering. On April 21, the Pentagon unveiled Golden Dome — a $17.9 billion “system of systems” designed to protect the continental United States against hypersonic glide vehicles, cruise missiles, and advanced ballistic threats from China and Russia. South Korea is accelerating its own Korean Air and Missile Defense system to 2029, two years ahead of schedule, investing 842 billion won to counter North Korea’s expanding long-range artillery. Twenty-four European states have joined the German-led European Sky Shield Initiative, with Berlin procuring Israel’s Arrow 4 to plug the continent’s most dangerous gap. NATO’s own ballistic missile defence network intercepted Iranian missiles targeting Turkey in March 2026 — a first operational test that proved both the system’s worth and Europe’s vulnerability.

Everyone, it seems, needs an Iron Dome. The question is: what does one actually cost — and what does it cost to go without?

The Interceptor Burn Rate

Israel understood early that missile defence, however expensive, is cheaper than absorbing strikes. The recent conflicts have vindicated that logic — and exposed its fragility. During the June 2025 twelve-day war with Iran, the United States fired approximately 150 THAAD interceptors — roughly a quarter of its entire purchased inventory — and around 80 SM-3 missiles from naval vessels. Within days of the February 2026 strikes, estimates suggested that Arab countries using American systems may have burned through 800 PAC-3 MSE or THAAD interceptors. Stockpiles that took years to build were consumed in days.

The interceptors were fired because the assets being defended — populations, military bases, energy chokepoints — are worth incomparably more than the missiles expended to protect them. The Strait of Hormuz, carrying roughly twenty per cent of the world’s oil supply, sits within range of the very weapons these systems were built to stop. But the rate of consumption has strained production capacity to breaking point, and the defence industrial base cannot replenish fast enough to keep pace with the threat.

The Brutal Arithmetic of Defense

Here is where the economics turn savage. A Patriot interceptor costs roughly $4 million. A THAAD round runs $12 to $15 million. An Iranian Shahed-136 drone costs perhaps $20,000. When two AN/TPY-2 radars — each valued at approximately $1 billion — were reportedly disabled by drones costing $30,000 apiece, the attacker achieved a cost advantage of more than 30,000 to one.

This asymmetry is deliberate. Iran’s strategy of launching large mixed salvos — cheap drones alongside ballistic missiles — is designed not merely to penetrate defences but to exhaust them. Each wave forces the defender to spend millions neutralising threats that cost thousands to produce. Russia operates on the same logic in Ukraine: Iskander missiles produced for $400,000 to $500,000 force interceptions costing $4 million each. Six Iskanders can cost Ukraine $48 to $72 million to defeat — vastly more than Russia’s production outlay.

The Cold War-era Nitze Criterion held that a defensive weapon is only worth deploying if this cost ratio favours the defender. That criterion is being violated on a grand scale. Yet nations are deploying anyway, because the alternative — undefended cities, exposed bases, vulnerable energy chokepoints — is simply unacceptable.

The Race Against the Production Clock

The central problem is no longer whether to build missile defence, but whether it can be built fast enough. Golden Dome’s architecture is divided into “epochs” — capability milestones due by 2026, 2028, 2030, and beyond. But the Pentagon’s own analysts acknowledge that the programme is already spinning its wheels: agencies with acquisition responsibility have not yet received funding, and industry will not commit capacity until dollars arrive. The $185 billion price tag may itself be a fantasy — one independent estimate placed the true cost at $3.6 trillion.

Europe faces an even steeper climb. Analysts estimate five to ten years to establish robust continental air and missile defences. As one NATO adviser bluntly put it, Europe cannot currently protect Rotterdam, Rome, and its population centres simultaneously. The twenty-four states in the European Sky Shield Initiative have selected their systems — IRIS-T, Patriot, Arrow — but production lines are backlogged and the American defence industrial base cannot meet European demand. The Pentagon paused air defence interceptor deliveries to allies as stockpiles reached critically low levels.

South Korea’s acceleration — shaving two years off its timeline — reflects the starkest recognition of all: the threat is not waiting for procurement schedules.

The Ukrainian Answer

While governments spend billions on next-generation missile shields, the most disruptive innovation in air defence has emerged from a country that could not afford one. Ukraine produced roughly four million drones in 2025 — exceeding the combined output of all NATO members — and is targeting seven million in 2026. Before Russia’s full-scale invasion, Ukraine had about seven domestic drone manufacturers. It now has approximately 500. The Pentagon, having concluded that no American manufacturer can match the price, delivery times, or battlefield-tested reliability, is now purchasing Ukrainian counter-drone technology and deploying it at bases in the Middle East.

The logic is brutally simple. An FPV interceptor drone costs as little as $150. A Patriot interceptor costs $4 million. Using the former to destroy cheap incoming drones and reserving the latter for ballistic missiles transforms the cost-exchange ratio from catastrophic to manageable. Ukraine’s Sky Map command-and-control platform — built from acoustic sensors, smartphones mounted on poles, and AI-driven tracking — coordinates layered drone defences across wide territories at a fraction of the cost of conventional systems. Germany has signed a €4 billion defence partnership to gain access to this battle-tested technology in exchange for Patriot missiles. At least eleven countries are now seeking Ukrainian drone defence expertise, with several having signed long-term agreements.

Ukraine’s contribution is not a weapon system. It is an organisational revolution — a distributed, fast-iterating production model that turns the attacker’s cost advantage on its head. Where expensive interceptors bleed the defender’s balance sheet, cheap interceptor drones bleed the attacker’s swarm.

The Laser Horizon

One technology could eventually break this punishing arithmetic. Israel’s Iron Beam laser engages targets at roughly $2 per shot — a cost ratio that would invert the attacker’s advantage overnight. Until directed energy systems mature and scale, however, the world remains trapped: missile defence is strategically essential and economically brutal.

The Price of Going Without

Iron Dome’s fifteenth birthday is not a celebration of one country’s ingenuity. It is a proof of concept that has reshaped how every nation calculates its security. The cost of missile defence is high and rising. The only thing more expensive is not having one.
