NATO drills in secret London bunker expose drone gap as UK faces funding battle

Deep inside Charing Cross underground station, in a disused Jubilee line terminus, a secret NATO command bunker has been operating discreetly this week, hosting a war game that simulated defending Estonia from a Russian invasion in 2030. Dozens of mostly British soldiers worked below, unaware to commuters and tourists above.

The hidden chambers are behind two sets of normally locked metal double doors. A red glow at the base of an escalator signals the troops below; next are mocked-up newspaper covers pasted over aging advertisements, blaring that a British NATO force has deployed to Estonia in response to a Russian military buildup on the border.

“The scenario you are about to see is very deliberately set in 2030 because that is where we see the threat from Russia to be at its most acute,” said Lt Gen Mike Elviss, commander of the Allied Rapid Reaction Corps, in a video briefing. Military analysts estimate that if the war in Ukraine ends, a remilitarized Russia could be ready to attack Europe again by that year.

The exercise’s ostensible aim is to show Moscow that, despite former President Donald Trump’s bluster, NATO is operationally ready to defend its most exposed Baltic members. But a more important audience sits about a mile away in Westminster, where the Ministry of Defence has been locked in a funding battle with the Treasury for months.

Remodeling the British army will cost billions in investment, particularly for drones, officials say. It is estimated that £50 million a year is needed to get the arms industry building required volumes of simple one-way attack drones, so familiar in Ukraine, and £500 million a year for more sophisticated models such as armed driverless vehicles.

If a full-scale war in eastern Europe erupted tomorrow, the British military would run out of drones in less than a week, able to launch only a few hundred a day, according to military assessments. On that basis, the army is between 80% and 90% short of the drones it needs for reconnaissance, air defense or attack.

The exercise, Arrcade Strike, is meant to show “the strategic reserve corps that you could have by 2030,” Elviss said. Three junior defense ministers visited the secret bunker on Wednesday, though Secretary of State John Healey was tied up on official business and visiting Estonia, where the bulk of the UK’s 4th Brigade is deployed as part of a related exercise.

Chairs, computers and screens crowd the underground hall, spilling onto a platform—a temporary Ukraine-style bunker ready for a simulated war influenced not only by the conflict in Ukraine but also the recent U.S. attack on Iran. In theory, the command center can house 500 people, transmitting 10 terabytes of data a day, equivalent to three months of Netflix.

What follows is carefully choreographed. To explain the mission, attending journalists were invited to put on virtual reality headsets supplied by U.S. technology company Anduril (U.S. Vice President JD Vance is an investor), which display a 3D model of the battle plan. In this glossy, computerised vision of war, the first waves of drones are lost but Russian positions quickly located and eliminated.

The operation is spelled out explicitly: a NATO force would use thousands of drones or more to lead a counterattack against Russian forces, revealing and knocking out enemy air defense, other positions and headquarters with the help of fighter jets and artillery all the way to St. Petersburg from the border. It is not meant to be subtle; the rehearsals are conducted “because the adversary is watching,” Elviss said.

One intention is to visualize the British army’s Project Asgard, a digital communication system that uses artificial intelligence (Hivemind, from U.S. firm Shield AI is referenced) on the battlefield, linking any surveillance node to any weapon. The key purpose of AI is to speed up decision-making, including target acquisition, from 72 hours to two hours, following the lead of the Israeli and U.S. militaries.

A virtual target is identified, though it is not shown how. The exercise includes a new deep strike unit able to hit targets 90 miles away with M270 artillery—meaning it could bomb Leicester if the rocket launcher was in Charing Cross.

Three bombing options are offered from a drop-down menu, chosen with the help of artificial intelligence based on available weapons. An icon is selected, a new screen loads, and toward the bottom, a red flashing fire button appears.

It falls to NATO’s military chief Gen. Alexus Grynkewich, an American, to applaud British efforts “to transform into an AI-fuelled command post,” in a video message. If AI made a mistake during Arrcade Strike, nobody appeared aware of it, though in any event this was a demonstration.

This is war in 2026 as well as 2030: a high-speed, hi-tech means of dealing death from a distance from the relative safety of deep underground. Meanwhile, at the Ministry of Defence, early hints suggest that next month several billion more will be found to increase the defense budget to close an £18 billion funding gap—and begin paying for the British army of the near future.
