Russia's Arctic military buildup sparks Cold War-level fears in the West

Russia’s military presence in the Arctic and High North has raised serious concerns among Western defence officials. In February 2026, the UK Defence Secretary warned that Moscow now poses the greatest security threat to the region since the Cold War. The warning comes as analysts highlight gaps in Britain’s own defence capabilities.

The UK’s ability to respond swiftly to emerging threats has been questioned. Defence experts point out that the British Army may struggle to deploy even a single division at short notice. Meanwhile, limited air defence and maritime resources have left the country vulnerable to drone attacks.

Russia’s position in the High North remains deeply entrenched. Its naval, air, and nuclear-linked operations—such as the March 2026 deployment of the ballistic missile submarine *Knyaz Vladimir* from the Kola Peninsula—underline a long-term strategic focus. Analysts warn that these capabilities can be rebuilt and expanded over time. In response, security planners are pushing for a more coordinated approach. The *Atlantic Bastion* concept, backed by the Atlantic Council, calls for stronger North Atlantic cooperation. Key priorities include counter-submarine operations and safeguarding undersea infrastructure, now seen as critical to deterrence in the region. Dr Anna Wieslander, Director for Northern Europe at the Atlantic Council, has emphasised the need for a unified strategy. Her office in Stockholm has tracked Russia’s persistent military investments, stressing that the challenge is both enduring and complex.

The UK faces growing pressure to address its defence shortfalls while countering Russia’s Arctic ambitions. Protecting undersea cables and countering submarine threats are now central to regional security plans. Without stronger capabilities, analysts warn, Britain risks overstretching its commitments at a time of heightened tension.
