Nine Northern European States Plan UK‑Led Maritime Alliance Against Russian Sub Activity
Nine Northern European countries intend to form a maritime alliance under UK leadership, based on the Joint Expeditionary Force, to counter Russian submarines in the North Atlantic, Baltic and Arctic seas and better protect sea lanes and undersea infrastructure.
Northern European governments are preparing a new maritime framework to push back against Russian submarine activity in some of the region’s busiest and most sensitive waters.
According to Ukrainian and other open reporting, nine countries — the Netherlands, Norway, Finland, Sweden, Iceland, Denmark, Lithuania, Latvia and Estonia — plan to form an alliance led by the United Kingdom. The structure would be built on the existing Joint Expeditionary Force, a UK‑centred grouping that already brings their militaries together.
The stated focus of the new arrangement is at sea. Participants aim to strengthen efforts against Russian submarines in the North Atlantic, the Baltic Sea and Arctic waters. These routes carry much of Europe’s trade and energy and host critical undersea infrastructure.
States around the Baltic and North Atlantic have grown more concerned about the vulnerability of seabed assets such as power cables, gas pipelines and data links. Reports of past damage to energy infrastructure in the region have added urgency to plans for tighter coordination.
A UK‑led maritime grouping would not require large new fleets from each participant. It would instead formalise shared surveillance, joint exercises and common planning for how to respond to suspicious or hostile underwater activity, including around offshore platforms and cables.
For Russia, the move signals that even as its campaign in Ukraine continues, its naval movements from northern bases toward the Atlantic and Baltic will face denser monitoring by neighbouring states working in concert with London.
Observers will be looking for the final text of any agreement: how far it goes in setting out rules for joint patrols, what investments it triggers in underwater sensors and repair capabilities, and how Moscow adjusts its deployments once the alliance begins operating.
