UK MPs warn of ‘glaring gaps’ in defences against Russia in Arctic

By the Editorial Team · Friday, October 23, 2026

UK lawmakers have reported critical deficiencies in the Royal Navy’s ability to counter Russian military and hybrid threats in the Arctic, citing shortages of key vessels and aging submarines. The committee called for a comprehensive government plan to improve naval readiness by 2030 to secure the High North and maintain the UK’s leadership within NATO defense efforts.

A report by UK lawmakers has identified significant shortcomings in the country’s naval capabilities necessary to counter Russia’s military activities in the Arctic region. The parliamentary defence committee highlighted that the High North—a strategic area encompassing the Arctic and parts of the Atlantic where Russia maintains nuclear submarine bases—has become more accessible due to melting ice and is increasingly central to the United Kingdom’s security concerns.

The committee pointed to a notable rise in hybrid threats emanating from the region, including sabotage of undersea energy infrastructure and data cables. Monitoring of shipping movements has shown Russian civilian fishing vessels spending extended periods near critical transatlantic communication cables, raising concerns about potential interference.

To address the challenges posed by Russian submarines and possible sub-sea attacks, the report emphasized the UK’s need to deploy anti-submarine frigates and amphibious ships. However, lawmakers noted “shortages” in these naval assets and reported “poor availability” of destroyers and submarines capable of operating beneath the Arctic ice. The Royal Navy’s frigates and nuclear submarines were described as aging and increasingly prone to maintenance difficulties.

The United Kingdom currently leads a Joint Expeditionary Force comprising 10 NATO member states with a mission to secure the High North and Baltic Sea regions. This alliance is designed to offer rapid responses to hybrid threats. However, the report underscored that the UK must address critical gaps in the readiness and availability of its maritime forces to fulfill a leadership role effectively.

The committee also urged the government to reassess the value of this force and consider whether resources should instead be concentrated on NATO efforts. Highlighting growing security risks, the report cited concerns voiced by then-Prime Minister Keir Starmer in June regarding a possible Russian attack on a NATO ally as early as 2030. It called on the government to produce a clear plan outlining how the Ministry of Defence will enhance vessel availability by that year.

While the UK’s regular training exercises for Royal Marines in Arctic conditions remain a strength, lawmakers warned that such efforts cannot compensate for deficiencies in the naval fleet. They stressed that Britain’s armed forces must achieve significant improvements in maritime capacity and readiness to counter emerging threats from Russia effectively.
