With the introduction of the Israeli Arrow-3 air defence system, Germany has taken one of the biggest strategic steps in its modern military history. For the first time, a European country has a missile shield that can intercept incoming ballistic missiles even before they enter the atmosphere. A system that has proven itself not only in tests, but also in a real war situation — during the massive Iranian attack on Israel in April 2024.
System tested during Iran’s attack
In the early morning, Iran launched hundreds of projectiles towards Israel: drones, cruise missiles and above all ballistic missiles. The latter posed the greatest threat. Ballistic missiles first rise tens of kilometres into space, then descend at enormous speed towards their target. During that attack Iran fired variants of the Shahab-3 and Ghadr-110, among others, two of the heaviest weapons in the Iranian arsenal.

The size of those missiles makes the threat all the clearer. The Shahab-3 and Ghadr-110 belong to the category of medium-range missiles and are between 15.6 and 16.6 metres long, with a diameter of about 1.25 to 1.38 metres. These are giants of steel, fuel and explosives — objects that dive back into the atmosphere at speeds above Mach 10, sometimes even towards Mach 15, depending on their flight profile. The kinetic energy of such an object is enough to destroy entire city districts.
And yet Israel managed to bring most of the ballistic missiles out of the sky before they could cause damage. Arrow-3 played a leading role in this. The system was specifically developed to intercept this type of missile outside the atmosphere — at altitudes of up to hundreds of kilometres. Where systems such as Patriot only intervene within the atmosphere, Arrow-3 already works in the exo-atmosphere, well before the missile begins its fatal dive towards earth.
During the attack, the missiles involved were many times larger than the interceptors that brought them down. Because the most impressive thing about Arrow-3 is not only its performance, but the scale at which that performance is delivered. The interceptor is relatively small compared with its targets: it fits in a launch tube with a diameter of only 21 inches (about 53 cm). The missile itself is slender, aerodynamic and light enough to manoeuvre very quickly. Despite its compact size, Arrow-3 has a kill vehicle that does not destroy its target with an explosive charge, but purely through kinetic energy — a direct collision that literally pulverises the incoming projectile.
It is a remarkable piece of engineering: an Iranian attack missile 16 metres long and more than a metre thick, with enormous mass and speed, is hit by an interceptor barely wider than a sturdy traffic post. That Arrow-3 manages to hit such targets in space, under war conditions and under time pressure, shows the exceptional level of technological sophistication.
Arrow-3’s success during the Iranian attack strengthened the system’s reputation worldwide as perhaps the best long-range defensive weapon in the world.

The German armed forces.
From now on, the German armed forces have a layer of defence that Europe did not have before. Where most European countries depend on systems that can intervene in the final phase — such as Patriot — Arrow-3 offers protection on a completely different scale. The missile can intercept an enemy projectile thousands of kilometres from the German border, at enormous altitude. This means the system can protect not only Germany, but indirectly large parts of Europe.
The strategic significance is enormous. Russia has a large arsenal of ballistic missiles. Although nobody hopes they will ever be used against NATO territory, the threat does exist. Until now, Europe lacked a reliable way to neutralise that threat at long range. With Arrow-3, that changes. Military analysts rate the system’s success rate as high — based not only on tests, but above all on its operational use in Israel. In practice, Arrow-3 has been shown to bring ballistic missiles out of the sky with impressive precision.
Arrow-3 as a defensive weapon.
Germany presents Arrow-3 as a purely defensive investment, intended to protect cities, energy infrastructure and military bases against long-range weapons. But the system also acts as a deterrent. A country that knows its ballistic missiles will not get through the defence anyway will be less quick to launch an attack. In that sense, Arrow-3 contributes not only militarily, but also politically and strategically: it stabilises.
With Arrow-3 entering service, Germany takes a clear step towards a new European security model. The system forms the upper layer of the European Sky Shield Initiative (ESSI), in which several countries are working on a shared air defence. Below Arrow-3 come Patriot and IRIS-T, which operate at lower altitudes. The result is a layered shield that gives Europe a level of protection it has never had before.
That a relatively slender interceptor can destroy a much larger and faster attack missile makes Arrow-3 perhaps the most impressive missile defence system of the moment. And although everyone hopes it will never have to be used against an enemy attack on Europe, the presence of this system in Germany gives a sense of security that was long missing.
