UK steps up defence of Arctic and High North

Royal Navy submarine breaks through Arctic ice for major exercise

The Ministry of Defence (MoD) has confirmed a significant escalation of the United Kingdom’s military commitment to the Arctic and High North, responding to heightened regional security concerns.

Defence Secretary John Healey announced that the number of British personnel deployed to Norway will double over the next three years, rising from 1,000 to 2,000 troops. This expansion aligns with the government’s pledge to increase defence spending to 2.6% of GDP by 2027, signalling a long-term investment in northern flank security and providing a clear demand signal for the UK defence supply chain.

The operational tempo in the region is set to increase through a series of major exercises and missions that present diverse requirements for sub-contractors and service providers. In September 2026, the UK-led Joint Expeditionary Force (JEF) will initiate Exercise Lion Protector. This large-scale manoeuvre will involve air, land, and naval assets across Iceland, Norway, and the Danish Straits, focusing on the protection of critical national infrastructure and the refinement of joint command and control systems. Additionally, the deployment of 1,500 Royal Marine Commandos for NATO’s Exercise Cold Response in March 2026 underscores the ongoing need for specialized cold-weather equipment, logistics, and sustainment services tailored for extreme environments.

Strategic industrial opportunities are also emerging from the Lunna House Agreement, a bilateral accord between the UK and Norway signed in late 2025. This agreement mandates the joint operation of Type 26 submarine-hunting frigates and the expansion of joint training initiatives. For the maritime supply chain, this necessitates a focus on anti-submarine warfare (ASW) technology, sensor integration, and fleet maintenance. Furthermore, the provision for pre-positioning British military equipment in Norway suggests future contracts related to infrastructure, storage, and the long-term readiness of hardware stationed abroad.

The UK’s role in the upcoming NATO Arctic Sentry mission further cements the High North as a primary theatre for British defence policy. As the Strategic Defence Review emphasises the necessity of improving NATO’s deterrence posture in Northern Europe, the MoD is expected to accelerate the procurement of technologies that enhance situational awareness and operational resilience in the Arctic Circle. For businesses seeking to engage with the MoD, these developments offer a stable framework for investment in capabilities that support high-intensity operations and multinational interoperability in one of the world’s most challenging strategic environments.

ZeroUSV welcomed recently representatives from the Royal Navy, MOD and NSO (National Shipbuilding Office) to Manor Marine’s headquarters in Portland for a VIP tour showcasing the company’s expanding autonomous maritime capabilities. The visit follows ZeroUSV’s recent strategic investment in Manor Marine, strengthening the partnership and boosting sovereign UK production capacity for the company’s Oceanus class uncrewed surface vessels (USVs). During the tour, guests were shown around Manor Marine’s facilities and given an update on the ongoing build of ZeroUSV’s next-generation Oceanus17 platform, which remains on track to be launched in July this year. The tour demonstrated ZeroUSV’s ability to rapidly scale production of advanced British-built autonomous vessels, while highlighting the strength of UK sovereign shipbuilding and innovation within the maritime defence sector. Designed for long-range, over-the-horizon operations, Oceanus17 represents a significant step forward in modular, multi-role autonomous maritime capability. The 17-metre platform features a 4-tonne payload capacity and a 20ft ISO-compatible mission deck, enabling rapid reconfiguration for a wide range of defence, security and commercial maritime missions. Matthew Ratsey, Managing Director of ZeroUSV, said: “It was a pleasure to welcome representatives from the Royal Navy and MOD, and showcase the progress being made across our Oceanus programme. “The visit highlighted not only the pace at which we are developing advanced autonomous capabilities, but also the strength of British engineering and sovereign shipbuilding. Through our partnership with Manor Marine, we are building the foundations needed to deliver scalable, mission-ready USV capability for both defence and commercial applications.” Picture caption: Matthew Ratsey with the VIP tour aboard the Oceanus17 vessel
