Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to his Department’s press release entitled ‘UK steps up defence of Arctic and High North from rising Russian threats,’ published on 11 February 2026, what assessment he has made of the severity of the security threat posed by Russian military activity in the Arctic and High North.

The Ministry of Defence continuously monitors Russia’s military posture in the Arctic and High North as part of routine defence intelligence and strategic assessments. While the UK and NATO recognise Russia’s status as an Arctic state with a legitimate presence in the region, its increased militarisation of Arctic territory in recent years, including investments in bases, air and coastal defence capabilities, and Arctic-capable equipment, is a cause for concern.

Russia is steadily increasing its military presence and activity in the region, with notable increases in submarine activity in the North Atlantic. Although this activity does not breach international law, it poses challenges to the interests of the UK, NATO Allies, and partners, necessitating vigilance and preparedness.

The UK remains committed to working closely with NATO Allies and partners to uphold shared security in the Arctic and High North. Efforts focus on strengthening deterrence through enhanced situational awareness, air and maritime activity, and collective defence planning. This commitment was underscored at the recent NATO Defence Ministerial Meeting, where Arctic security was a key theme.

During the meeting, NATO’s Secretary General announced the launch of Arctic Sentry, a new enhanced vigilance activity aimed at synchronising national, bilateral, and multilateral efforts in the region under a unified approach. The UK is playing a leading role in these efforts, including the planned deployment of the Carrier Strike Group, led by HMS Prince of Wales, later this year.
