Iranian missiles could target these seven UK sites | UK | News

Britain’s Defence Secretary has declined to give a clean assurance that Iran lacks the firepower to hit the UK, even as he sought to calm fears by stressing that no strike on British soil is believed to be in the planning.

John Healey was pressed repeatedly during a Sky News interview on the question of whether London itself could be within range of Iranian missiles — a line of questioning he navigated carefully without offering an outright denial.

“We have no assessment of Iranian plans to strike London,” he said.

The exchange came after Iran fired missiles towards Diego Garcia — the remote Indian Ocean atoll that doubles as a joint British and American military installation. Healey had previously told Parliament the incoming rounds fell well short of the island.

And so with the danger of Iranian missiles raining down on the UK not discounted by the government, the question of which exact locations are in danger comes into sharp relief.

Is London at risk?

Military analysts have been less reassuring than the Defence Secretary. Both the Israeli Defence Forces and the Institute for the Study of War have placed London inside what they describe as a theoretical 2,500-mile danger radius — the outer reach of Iran’s most advanced modified intermediate-range ballistic missiles, a category that includes the Khorramshahr-4.

UK sites at elevated risk due to the Iran conflict

The locations below have been singled out by analysts as facing a heightened threat environment directly linked to the active hostilities between the West and Iran in 2026:

RAF Fairford, Gloucestershire — The airfield serves as the principal launch point in Britain for US Air Force strategic bombers — B-1B Lancers and B-52 Stratofortresses among them — currently conducting operations against Iranian missile sites, placing it near the top of any Iranian target list.

Portsmouth and Devonport, Plymouth — Two of Britain’s most consequential naval addresses: between them they berth roughly two-thirds of the Royal Navy’s warships, making them obvious candidates for any strike aimed at crippling British sea power.

GCHQ, Cheltenham — As the nerve centre of Britain’s signals intelligence and cyber defence operations, the doughnut-shaped complex would represent a high-value objective for any adversary seeking to blind rather than destroy.

RAF Fylingdales, North Yorkshire — The moorland radar station performs a function that makes it irreplaceable in any missile conflict: tracking incoming ballistic projectiles from the moment of launch. The BBC has identified it as a priority counter-force target for precisely that reason.

Barrow-in-Furness — The Cumbrian shipyard where Britain’s nuclear submarines take shape has been assessed by analysts as sitting in an uncomfortable position — significant enough to attract attention, yet described as ‘woefully exposed’ to the kind of long-range strike Iran is now capable of contemplating.

UK sites targeted for their strategic and nuclear value

A further set of locations draws its threat profile not from the current conflict specifically but from the permanent strategic weight it carries — as home to Britain’s nuclear capability, its principal naval base and its defence supply chain:

Faslane, HMNB Clyde — Scotland’s deep-water naval base on the Clyde is the permanent home of Britain’s Trident-armed submarines — the physical embodiment of the UK’s nuclear deterrent.

Telford, MOD Donnington — Inland and unglamorous, the Shropshire depot nonetheless underpins the logistics chain that keeps British armed forces equipped and operational.

For now, Healey’s position holds: no plans, no imminent threat, no cause for panic. But with Iranian missiles already in the air over the Indian Ocean and London named in analyst threat assessments, the margin for reassurance is narrowing.
