A parliamentary committee has concluded that Britain's defences in the far north are thin in ways that could be exploited, with too few warships and submarines to guard the undersea cables, energy lines and Atlantic routes on which the country depends.

MPs Warn of 'Glaring Gaps' in UK Arctic Defence as Russia Eyes the High North
"Glaring gaps" in defending the Arctic, MPs warn
Mark
Why does a report about the Arctic matter to someone living in Britain?
Mimi
Because the exposure the MPs describe is close to home: undersea cables, energy supplies, and the Atlantic supply routes from the US. Those are things ordinary life depends on.
Mark
What is the specific weakness they point to?
Mimi
Too few warships and submarines, and what they call a shockingly low availability of submarines. There's also a temporary loss of the ability to operate under Arctic ice.
Luke
Worth being clear that this is a committee's assessment. The report says Russia could use the ice to hide its submarines, but that's a warning about capability, not a description of any attack or confirmed plan.
Mark
But the MoD itself has said something about Russian activity, hasn't it?
Mimi
Yes, earlier this year it said Russian submarine activity in the North Atlantic is back to Cold War levels. That gives the committee's concern some official footing.
Luke
Fair, though the 2030 timeline comes from Starmer's earlier warning, repeated by Stuart Anderson. It's a political warning, not a date anyone has established.
Mark
What does the report suggest beyond buying more ships?
Mimi
It asks whether the Joint Expeditionary Force, the UK-led northern European coalition, should focus more on the High North, given uncertainty over US support for Nato.
Luke
And note it only says the UK should consider that. The MoD says the force is already strengthening Nato's northern flank, and we don't know yet whether anything changes.
Le Pouls
- MPs have declared 'glaring gaps' in UK Arctic defence, and the Royal Navy's thin fleet of warships and submarines is under sharp scrutiny.
- Undersea cables and energy supplies sit exposed, and Russian submarines could hide beneath Arctic ice while threatening Atlantic sea lanes.
- Opposition voices argue that with war with Russia potentially possible by 2030, delay is the real danger and spending must start now.
- The Ministry of Defence insists it is investing heavily in cable protection and that the Joint Expeditionary Force is already reinforcing NATO's northern flank.
- Whether the Joint Expeditionary Force turns decisively toward the High North, and whether funding moves at the pace MPs demand, remains unresolved.
A parliamentary committee has concluded that Britain's defences in the far north are thin in ways that could be exploited, with too few warships and submarines to guard the undersea cables, energy lines and Atlantic routes on which the country depends. The warning rests on a sober reading of the Arctic as a harsh and contested frontier, where ice can shelter a rival's submarines and where Russia is seen as seeking military advantage. It arrives at a moment when the old assumption of American backing for the alliance can no longer be taken for granted, and when many in Westminster feel that time, as much as money, has become the scarce resource.
A committee of MPs has found that the United Kingdom has "glaring gaps" in its ability to defend the Arctic, leaving the country open to possible Russian attack. The Commons Defence Committee's new report focuses on the High North, the Arctic circle and the regions around it, and its core complaint is one of hardware: the Royal Navy lacks enough warships and submarines to protect critical infrastructure, especially undersea cables and energy supplies.
The MPs single out submarines, describing their availability as "shockingly low" and noting a temporary loss of the ability to operate beneath Arctic ice. That matters because Russia could use the ice as cover for its own submarines while threatening NATO sea lanes, British infrastructure and the nuclear deterrent. The committee's chair, Tan Dhesi, called the Arctic a hostile environment that Russia seeks to dominate, and said work to close the gaps "cannot start soon enough."
The warning follows reports that Russian submarine activity in the North Atlantic has returned to Cold War levels, and a prior warning from Sir Keir Starmer that Russia could attack NATO by the end of the decade. The Conservative shadow minister Stuart Anderson argued that time is as important as money, and that deterrence requires readiness now rather than delay.
The report also asks whether the UK-led Joint Expeditionary Force should concentrate more on the High North, given uncertainty over US support for NATO. The Ministry of Defence says it is clear-eyed about the Russian threat and is investing heavily in protecting undersea cables, and that the Joint Expeditionary Force is already strengthening the northern flank. Whether the government adopts the committee's call for a northward shift, and whether funding follows the pace MPs are urging, is still to be seen.
A committee of MPs has concluded that the United Kingdom has "glaring gaps" in its ability to defend the Arctic, and that those gaps leave the country open to potential Russian attack. The finding comes from the Commons Defence Committee, whose new report centres on the High North, the area that includes the Arctic circle and the regions next to it.
The core of the complaint is hardware. The committee says the Royal Navy does not have enough warships and submarines, and that the shortfall leaves critical infrastructure exposed. It names undersea cables and energy supplies specifically. In a conflict, the report adds, Russia could threaten the UK's population, its civilian and military infrastructure, and the vital supply routes that run across the Atlantic from the United States.
The MPs single out submarines in particular. They describe a "shockingly low availability" of boats and note a temporary loss of the ability to operate them beneath Arctic ice. That matters, the report argues, because Russia can then use the ice to hide and protect its own submarines while threatening Nato sea lanes, UK critical infrastructure and the UK's nuclear deterrent.
The committee's chair, Tan Dhesi, put it plainly. The Arctic, he said, is a demanding, hostile environment, and one that Russia, which he called the country's greatest adversary, is seeking to dominate for military advantage. Work to close the gaps, he added, "cannot start soon enough."
The report arrives against a backdrop of rising concern. Earlier this year the Ministry of Defence said Russian submarine activity in the North Atlantic had returned to Cold War levels. Sir Keir Starmer, now the former prime minister, had previously warned that Russia could attack Nato by the end of the decade.
That timeline shaped the response from the opposition benches. Stuart Anderson, the Conservative shadow minister for war readiness, said that if Nato could be at war with Russia as soon as 2030, as the former prime minister cautioned, then time is just as important as money. To deter war, he said, the country must be ready for it, which means spending now rather than "kicking the can down the road until it's too late."
The report also looks beyond British ships and submarines. With uncertainty over US support for Nato, the MPs say the government should consider whether the Joint Expeditionary Force, a UK-led military coalition of northern European nations, ought to concentrate more on the High North.
The Ministry of Defence responded that it is "clear-eyed about the threat Russia posed" and is investing heavily in protecting Britain's undersea cables. A spokesperson said the Joint Expeditionary Force is already strengthening Nato's northern flank and increasing the ability to respond rapidly to emerging threats. What remains to be seen is whether the government accepts the committee's call to shift the force's focus northward, and whether funding follows on the timetable the MPs are urging.
