Iran missile range map: Which European cities are now within reach? ~ PARN HARIT

With Iran having ramped up its missile strikes across the Middle East, and most recently, even reaching the Diego Garcia military located in the Chagos Islands, an important question has come up: what distances Iranian missiles can travel to. Israel has already warned that European cities may be well within reach of Iran’s long-range missiles.

The Israel Defense Forces (IDF) said this was the first time Iran had launched a long-range missile since the current conflict began.

In a statement, the IDF said: "We have been saying it: the Iranian terrorist regime poses a global threat."

Israeli Prime Minister Benjamin Netanyahu also warned that Iran could strike "deep into Europe".

"They have now the capacity to reach deep into Europe," he said. "They already have fired on a European country, Cyprus. They are putting everyone in their sights."

According to the Israeli military, the missiles involved could have a range of around 2,400 miles (4,000km), potentially placing cities such as London, Paris and Berlin within reach.

Diego Garcia lies about 2,360 miles (3,800km) from Iran. The fact that missiles were launched towards the base has raised questions about whether Iran's capabilities extend further than previously assessed.

Military analyst Sean Bell told Sky News: "All of a sudden, the UK is not far away either… London is not. The UK has no effective ballistic missile defence system in place, and therefore, this is a very worrying development."

What Do We Know About Iran's Missile Range?

Iran's missile capabilities are not fully understood, particularly after recent strikes on its infrastructure.

Before the latest developments, analysts believed Iran's longest-range system was the Khorramshahr-4 missile, with an estimated reach of between 1,200 and 1,900 miles.

The attempted strike on Diego Garcia has led to concerns that Iran may now be capable of longer-range launches than previously thought.

General Richard Barrons, a former head of the UK's Joint Forces Command, told the BBC: "Previously we thought Iran's missiles had a range of 2,000km and Diego [Garcia] is 3,800km from Iran."

The UK government has sought to reassure the public that it remains secure. Housing Secretary Steve Reed said the country has defensive systems in place and would act to protect its interests if necessary.

"We didn't join the war, we're not going to be dragged into this war, but we will take necessary defensive action," he said.

He added that one of the missiles aimed at Diego Garcia had been intercepted while another failed, describing this as evidence that existing defences were working.

What Do Experts Say?

Some analysts caution that the full extent of Iran's capabilities remains uncertain. Danny Citrinowicz, a researcher at Israel's Institute for National Security Studies, said satellite imagery suggests Iran may be attempting to rebuild its missile production.

However, he suggested the recent launch may have been intended more as a signal than a precursor to wider attacks.

"It's not that they think that tomorrow they will attack London or Paris," he said, "but… it's another element that enables them to build the deterrence."

Overall, while concerns have increased following the Diego Garcia incident, there is no clear consensus on whether Iran currently has either the capability or the intent to strike European cities.

The strategic landscape of the current conflict shifted dramatically on March 21, 2026, when Iran demonstrated a missile capability far exceeding its long-claimed limit of 2,000 km.

By targeting the joint UK-US base at Diego Garcia—approximately 4,000 km from Iranian territory—Tehran has effectively placed almost the entirety of Europe within its strike radius.

European Cities Within Reach (March 2026)

Defense analysts and the IDF have confirmed that following recent launches, the "threat arc" now covers nearly every major European capital.

Region	Key Cities Now Within Range	Estimated Flight Time
Southeastern Europe	Athens, Bucharest, Sofia, Istanbul	10–12 Minutes
Central Europe	Berlin, Rome, Budapest, Vienna, Warsaw	15–18 Minutes
Western Europe	Paris, London, Madrid, Brussels, Amsterdam	20–22 Minutes
Northern Europe	Stockholm, Copenhagen, Oslo	20–25 Minutes

How the Range "Doubled" Overnight

For years, Iran publicly capped its ballistic missile range at 2,000 km (the reach of the Sejjil and Khorramshahr-4). However, experts now believe two factors have extended this reach to 4,000 km:

Multi-Stage Technology: Intelligence suggests Iran is using technology derived from its satellite launch vehicles (like the Qaem-100). By using a two-stage or three-stage rocket configuration, they can push a warhead significantly further into the "exo-atmospheric" phase before reentry.
Lighter Warheads: By reducing the payload from the standard 1,500 kg (found on the Khorramshahr) to a lighter 500–700 kg warhead, the range can be extended by over 1,000 km.

Strategic Implications

The shift from a regional threat to a continental one has triggered emergency sessions in Brussels. Former IDF officials have noted that because these missiles travel at hypersonic speeds (Mach 8–16) during their descent, existing European missile defense shields are currently "uneven and insufficient" to handle a saturated attack.

The reach of these systems has already impacted global oil supply routes and sparked a 48-hour ultimatum from the U.S.
