British Army turns abandoned Tube station into secret NATO war HQ to command troops on Russia’s doorstep
The British Army has transformed a disused London Underground platform into a NATO command post as part of a major exercise testing the UK’s ability to lead troops in the defence of Europe.

Exercise ARRCADE STRIKE saw parts of the former Charing Cross Tube station turned into a UK-led military headquarters, with commanders practising how they would direct large-scale operations on NATO’s eastern flank from deep underground.
The disused Jubilee Line platform, which famously featured in the James Bond film Skyfall, was taken over by the Army to test how NATO would respond if Article 5 was triggered by a Russian attack on a member state. The clause treats an attack on one ally as an attack on all, forcing the alliance to mobilise in defence of its territory.
Hundreds of military personnel from the UK, France, Italy and the United States took part, testing how NATO could plan and command operations involving up to 100,000 personnel across land, sea, air, space and cyberspace.
Defence chiefs said the underground setting was designed to reflect the growing threat posed to command posts by long-range missiles, drones and electronic surveillance.

The exercise also tested a digitally enabled headquarters using artificial intelligence and real-time data to help commanders make faster decisions on the battlefield.
Defence Secretary John Healey said the exercise showed the UK’s “NATO-first commitment” and its ability to “deploy at pace to command tens of thousands of troops to defend NATO territory”.
He said: “We are investing in our people and cutting-edge tech and stepping up on European security.”
The Ministry of Defence said the exercise was fictional, but the capabilities being tested were real and aimed at ensuring NATO forces can respond rapidly and effectively to threats.
It comes as Russia’s war in Ukraine continues to reshape European defence planning, with military leaders warning that NATO must be able to deploy, integrate and sustain forces at scale.
Lieutenant General Mike Elviss, Commander of the Allied Rapid Reaction Corps, said ARRCADE STRIKE was “an important milestone” in building a modern warfighting headquarters capable of deterring aggression and, if necessary, fighting and winning.
He added: “We are demonstrating the UK’s leadership within NATO and our determination to ensure the Alliance remains ready, resilient and credible.”
The MoD said the exercise also forms part of wider efforts to modernise the Army, including a £4 billion investment in drone capabilities.
More than 6,000 drone platforms have already been fielded to the Army, with thousands more one-way effector drones due to be delivered by the end of 2026.
General Chris Donahue, Commander of NATO Land Command and US Army Europe and Africa, said a UK-led Strategic Reserve Corps was “not optional” but “essential”.
