Iran has taken a leap that seriously worries the United States and Europe: has demonstrated for the first time that its missiles can reach targets located more than 4,000 kilometers. It is not only a technical advance, but a strategic change that expands the threat radius far beyond the Middle East and places European territory within its theoretical reach.
The clearest proof came with an attempted attack against the US base of Diego García, considered for years a practically untouchable enclave due to its remoteness. Located in the Indian Ocean, about 4,000 kilometers from Iran, it functioned as an “unsinkable aircraft carrier” key for military operations in the region.
However, that perception has changed. Warning systems detected two Iranian ballistic missiles aimed at the base. None impacted: one failed in flight and another was intercepted by a US SM-3 system. But the message was clear: Iran has managed to cover a distance that until now was considered out of reach.
A technical leap with many unknowns
It is still unclear what type of missile Tehran used. Among the hypotheses that analysts are considering is the Khorramshahr, known for its ability to transport heavy loads over long distances. Its usual range is around 2,000 kilometers, but it could be expanded if the weight of the warhead is reduced.
Another possibility is that Iran has adapted space rockets like the Simorgh for military use. In that case, the range would be greater, but at a cost: lower precision and reliability, something that would fit with the failure observed in the attack.
In any case, experts agree that it is not so much a weapon ready for mass use as a technological demonstration. Iran has proven that it can reach those distances, although still imperfectly.
Europe, within the new scope
The main consequence is geopolitical. If Iran can project missiles more than 4,000 kilometers, European cities become within its potential radius. This breaks with a line that the regime itself had maintained for years.
The 2,000 kilometer limit was not only technical, but also political. The supreme leader Ali Khamenei had defended this scope as a way to avoid tensions with Europe. The recent attack marks a break with that strategy.
For many analysts, the change also reflects an internal shift in Iranian power, with the Islamic Revolutionary Guard adopting a more aggressive stance and willing to take greater risks.
The answer: anti-missile shields
Although the movement has generated alarm, has not caught NATO completely off guard. For more than a decade, the Alliance has developed anti-missile defense systems in Eastern Europe precisely in response to the possibility that Iran would expand its reach.
One of the pillars is the Aegis Ashore system deployed in Romania, which uses SM-3 interceptors capable of destroying missiles in mid-flight through direct impact. This system is complemented by advanced radars in Türkiye and naval capabilities deployed in the Mediterranean.
At the national level, countries like Germany are also strengthening their defense with systems like the Arrow 3, designed to intercept missiles outside the Earth’s atmosphere, more than 100 kilometers high.
A shift in global deterrence
Although the attack on Diego García did not achieve its objective, Its importance is symbolic and strategic. Iran has shown that it can challenge the distances that until now limited its deterrence capacity.
As military analyst Michael Horowitz summarized, “The rules of the game have changed.” The threat is no longer just regional, and that forces us to rethink security in Europe and beyond.
In a context of growing tensions, this development does not necessarily imply an immediate conflict, but it does raise the risk bar. And, above all, it redefines what places They can be considered truly safe on the new geopolitical chessboard.
