Should the U.S. spend more on its military to counter Russia?
The United Kingdom and Northern European allies are preparing joint operations to counter Russian submarines across the North Atlantic, Arctic, and Baltic Sea. The initiative runs through the existing Joint Expeditionary Force framework, and no separate military organization is being established.
Why it matters
Growing Russian military activity has prompted closer operational coordination among allies, with protection of undersea communications cables a priority given their importance to international connectivity. The North Atlantic and Arctic have grown in importance to NATO due to shipping routes and undersea infrastructure.
An October investigation identified 17 Russian fishing vessels making more than 500 suspicious movements near undersea cables linking Britain with Europe and the US. The extraction does not detail how these movements were classified or what follow-up actions were taken.
The players
Joint Expeditionary Force
A UK-led multinational military framework of northern European allies that will expand its coordinated operations against Russian submarines.
Air Chief Marshal Sir Richard Knighton
Britain's Chief of the Defence Staff, who oversees the country's military leadership.
The details
Naval, air, and land forces will be brought into more closely coordinated operations within the Joint Expeditionary Force, improving allied ability to detect, monitor, and respond to Russian submarine operations. Hostile activities attributed to the Russian state, including targeted killings, sabotage, and cyberattacks, are cited as reasons for the expanded cooperation.
Timeline
October: An investigation identified 17 Russian fishing vessels near undersea cables.
November 8, 2026: The Financial Times reported the joint submarine-countering initiative.
Seasonal Patterns
The North Atlantic and Arctic have grown in importance to NATO as melting Arctic ice opens additional maritime routes. This initiative extends that strategic focus into coordinated operations against Russian submarines in those waters.
The initiative changes how allied navies and air forces coordinate in northern waters rather than creating a new military organization. Readers following defense policy should expect the expanded operations to be carried out within the existing Joint Expeditionary Force framework.
The takeaway
The expansion of the Joint Expeditionary Force shows allies responding to Russian submarine activity by tightening coordination within existing structures. Attention to undersea cables and northern shipping routes is likely to remain central to European security discussions.
