The Northern Navies Initiative will strengthen joint naval operations, military readiness and NATO’s maritime defence capabilities across the Baltic Sea, High North and North Atlantic.
The Royal Navy and its allies from 10 Joint Expeditionary Force (JEF) nations have signed a landmark agreement to strengthen maritime cooperation and enhance NATO’s defence capabilities across northern Europe, the Baltic Sea, the High North and the North Atlantic.
The agreement, known as the Northern Navies Initiative, aims to improve joint naval operations, strengthen military readiness and enable allied forces to respond more effectively to emerging security threats.
The agreement was signed by First Sea Lord General Sir Gwyn Jenkins aboard HMS Prince of Wales during the International Sea Power Conference in Oslo, Norway.
The initiative seeks to establish the JEF as NATO’s maritime vanguard in the North Atlantic, High North and Baltic Sea, allowing allied navies to coordinate their operations and integrate into NATO command structures when required.
Speaking after the signing, General Sir Gwyn Jenkins described the agreement as a significant step forward following nine months of work. He said like-minded nations had demonstrated what could be achieved through a shared commitment, adding that growing security threats demanded a collective response.
Under the agreement, naval forces from the 10 JEF countries will work towards common operational standards, conduct joint training, coordinate military planning and develop compatible equipment to improve interoperability.
The arrangement will also allow allied warships to share operational responsibilities, use each other’s ports for repairs and resupply, and coordinate maritime surveillance systems and uncrewed vessels.
A major objective is to ensure that future autonomous maritime platforms can operate across different national command and control systems. This would help create a more integrated naval force rather than maintaining 10 separate national capabilities.
The agreement comes amid growing strategic competition in the High North, where climate change, expanding economic activity and geopolitical tensions are reshaping the security environment.
It also seeks to address threats below the threshold of armed conflict, including potential attacks on critical undersea infrastructure, suspicious seabed operations and other forms of hybrid aggression.
As part of its broader maritime security strategy, the Royal Navy is preparing to bring the first phase of Atlantic Net, under the Atlantic Bastion programme, into operation within months. Developed in partnership with Ocean Infinity, the initiative aims to improve the detection of hostile underwater activity and strengthen protection of critical undersea infrastructure.
The UK says the enhanced surveillance capabilities will also give NATO and JEF allies a clearer picture of activity beneath the sea.
The Northern Navies Initiative builds on a Statement of Intent proposed by General Sir Gwyn Jenkins in London last April and reflects Britain’s wider efforts to strengthen European security through closer military cooperation.
Meanwhile, the Royal Navy is undertaking its most extensive fleet renewal programme since the Second World War, involving 280,000 tonnes of new steel. The figure could rise to approximately 450,000 tonnes if planned programmes are included.
The UK is also investing an additional £100 million to transform its Commando Force into a warfighting formation focused on the High North, including plans to increase the number of Royal Marines regularly deployed in the region.
The agreement highlights the growing importance of maritime cooperation between Britain and its northern European allies, with NATO providing the overarching collective defence framework and the JEF offering a smaller group of closely aligned nations capable of responding together with greater speed and readiness.
