MPs warn limited UK Arctic patrols could leave nuclear deterrent exposed
Developing story first seen 1 hour ago
The Commons Defence Committee has warned that the UK’s limited ability to operate beneath Arctic ice could let Russian submarines move undetected in a conflict. MPs say the wider gaps in Britain’s High North defences leave the public, critical infrastructure and the nuclear deterrent exposed, and need urgent attention.
The region is increasingly important as Russia sends spy vessels into UK waters and uncertainty grows over US support for European security. The committee cited an acknowledged anti-submarine warfare gap and low availability of ageing ships and submarines: five Type 23 frigates and six Type 45 destroyers are in service, compared with a requirement for 19 vessels. Eight Type 26 frigates are planned, but MPs urged ministers to keep existing ships in service until replacements arrive and to strengthen capabilities before 2030.
- MPs say the UK has temporarily lost its ability to operate submarines beneath Arctic ice.
- The shortfall could give Russian submarines room to move undetected in a conflict.
- The committee urges urgent action to address wider High North defence gaps.
Full account
The Commons Defence Committee has warned that weaknesses in the UK’s ability to operate in the High North could put British waters, undersea infrastructure and the country’s nuclear deterrent at risk. Its report describes the region as strategically important as Russia expands its military activity there, including submarine operations and alleged sabotage capabilities. The committee says the Ministry of Defence accepts that the UK has a serious shortfall in anti-submarine warfare.
The concern is that hostile submarines or sabotage forces could threaten the North Atlantic and the undersea cables and pipelines that carry communications and energy. In a conflict, the report says, Russia could also target the UK’s population and civilian and military infrastructure, as well as Atlantic supply routes from the United States. Committee chair Tan Dhesi argued that the UK does not currently have all the capabilities needed to operate effectively in the region, and called for urgent progress ahead of 2030, a date cited in the report as a possible timeframe for a Russian attack on Nato.
The committee points to the limited number and availability of Royal Navy vessels. The UK has five Type 23 frigates and six Type 45 destroyers in service, while the Navy’s stated requirement is 19 vessels. Type 23 frigates, equipped to detect submarines, are due to be replaced by eight Type 26 frigates, but construction is progressing slowly. The report also raises concerns about the availability of destroyers, frigates and attack submarines, with maintenance affecting the fleet’s ability to meet commitments.
The accounts also place the warning in the context of wider change in the Arctic, where retreating summer ice could make resources and shipping routes more accessible and draw greater military interest. The Mail report highlights the breakdown of HMS Protector, which it says has left the UK without a vessel specifically designed for polar expeditions, and refers to expected withdrawals of other crewed ships. The Independent report foregrounds the broader risks to infrastructure and the deterrent, while the Mail gives more attention to competition for Arctic resources, the ship breakdown and a reported Nato ranking of UK rearmament performance. These details are presented by that outlet and are not included in the other supplied account.
Where outlets differ
The Independent account focuses on the committee’s assessment of anti-submarine capability, the risks to undersea infrastructure and the nuclear deterrent, and the need to address weaknesses before 2030.
The Mail account adds claims about HMS Protector’s breakdown, planned withdrawals of eight other crewed vessels, Arctic resource competition and a reported Nato ranking for meeting rearmament commitments. Those points do not appear in the supplied Independent report.
The reports differ in emphasis and in the supporting details they include; both convey the committee’s warning about the UK’s limited anti-submarine capability and fleet availability.
