The UK Government says upgrades across Russia’s Northern Fleet and wider Arctic posture are being monitored in coordination with NATO, with hypersonic systems, ballistic missile submarines and modernised surface combatants identified as part of a growing threat environment.
Labour MP Graeme Downie pressed ministers about the commissioning of Borei-A ballistic missile submarines, the refit of Admiral Nakhimov, armed icebreaking patrol vessels and new Arctic infrastructure, including S-400 deployments on Novaya Zemlya. He also asked about hypersonic-capable missile systems and their implications for UK policy.
The MOD did not disclose detailed assessments, but views Russia’s naval modernisation as a factor in NATO’s current deterrence posture. Carns stated that the Ministry of Defence “keeps Russian military capabilities and investment under continuous review” and works with Allies to understand consequences for NATO security.
He added that Alliance planning is already evolving, saying NATO “is strengthening its deterrence and defence as a result of the increasing threat from Russia and will continue to adapt as necessary.”
On hypersonic systems within the Northern Fleet he said they are only one component within a broader set of Russian strike options. Carns highlighted investment announced in the Strategic Defence Review, including up to £1 billion for Integrated Air and Missile Defence, describing it as “a comprehensive and integrated approach to deterring and defending against the range of strategic threats we face.”
