The Joint Expeditionary Force (JEF), a 10-nation coalition led by the United Kingdom, has taken significant steps to address potential threats to critical undersea infrastructure in light of recent damage to a major Baltic Sea cable.
The UK-led initiative, known as Nordic Warden, integrates advanced artificial intelligence to monitor and mitigate risks posed by vessels, particularly those associated with Russia’s shadow fleet.
The activation of Nordic Warden follows the reported damage to the Estlink2 undersea cable on Christmas Day. Finnish authorities suggest the damage may have been caused by a tanker linked to Russia’s shadow fleet, which is used to bypass international sanctions. This incident has heightened concerns about the vulnerability of vital undersea communication and energy networks, underlining the need for coordinated international action.
Cutting-Edge Monitoring and Threat Assessment
Nordic Warden employs AI technology to analyse data from multiple sources, including the Automatic Identification System (AIS) used by ships to broadcast their positions. The system evaluates the risk posed by vessels entering designated areas of interest, focusing particularly on those identified as part of Russia’s shadow fleet.
When a potential threat is detected, the system initiates real-time monitoring and sends alerts to JEF participant nations and NATO allies. This proactive approach significantly enhances situational awareness and enables swift responses to potential threats.
Prime Minister Keir Starmer highlighted the significance of this initiative as part of the government’s Plan for Change, which prioritizes both growth and national security. “I am pleased we are launching this cutting-edge technology so soon after the JEF Summit to enhance European security and deliver on our Plan for Change,” he stated.
Reinforcing Collective Security
Nordic Warden builds on existing and planned NATO responses while showcasing the innovative capabilities of the JEF.
Defence Secretary John Healey emphasised the dual benefits of the system, which addresses both deliberate sabotage and cases of extreme negligence. “Harnessing the power of AI, this UK-led system is a major innovation which allows us the unprecedented ability to monitor large areas of the sea with a comparatively small number of resources, helping us stay secure at home and strong abroad,” he noted.
The initiative currently monitors 22 areas of interest, including parts of the English Channel, North Sea, Kattegat, and Baltic Sea. These operations are coordinated from the JEF’s operational headquarters in Northwood, where personnel from all member nations work collaboratively. The system’s capabilities were previously tested during the summer of 2024 and again during Exercise Joint Protector, which involved the deployment of over 300 UK personnel to Latvia.
A Unified Response to Emerging Threats
The JEF’s recent actions are part of broader international efforts to counter Russia’s shadow fleet and safeguard critical infrastructure. The UK has led a global alliance to disrupt these operations, sanctioning 93 oil tankers used by Russia to evade sanctions and fund its war in Ukraine. Additionally, the UK and several Baltic nations recently agreed to require proof of insurance from suspected shadow vessels traveling through key routes, further tightening security measures.
In a joint statement addressing the damage to Estlink2, the JEF expressed solidarity with Finland and Estonia while reaffirming its commitment to protecting shared interests. “This is another example of maritime incidents causing direct economic and security implications for Finland and Estonia, highlighting the risks to vital communication and energy networks essential for the security and prosperity of all our nations,” the statement read. The JEF also commended the decisive actions taken by Finland and Estonia in managing the incident.
Enhancing European Security
Nordic Warden exemplifies the JEF’s role as a high-readiness, adaptable force capable of responding rapidly to emerging threats. Comprised of Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway, the Netherlands, Sweden, and the UK as the framework nation, the JEF’s operations complement NATO’s efforts to maintain regional stability.
The initiative highlights the importance of technological innovation in modern defence strategies. By leveraging AI and collaborative intelligence, Nordic Warden demonstrates how allied nations can work together to protect critical infrastructure and deter potential adversaries. As Prime Minister Keir Starmer emphasised, such measures are integral to ensuring the security and prosperity of all nations involved.
The activation of Nordic Warden marks a significant milestone in the JEF’s mission to safeguard European security. By addressing both immediate and long-term threats, the initiative strengthens collective resilience and reinforces the alliance’s commitment to protecting vital undersea networks.
In doing so, it underlines the critical role of international cooperation in maintaining stability and safeguarding shared interests in an increasingly complex geopolitical landscape.
