MIND THE GAP VIII — STRATEGIC BALANCE IN THE NORTHERN THEATRE: THE WINDOW, THE RISKS, THE RECKONING
By Robin Ashby, Director General UK Defence Forum; Rapporteur, High North Observatory
The Window
There is, at present, a window. It is not a matter of optimism. It is a matter of arithmetic.
Russia retains what matters most for strategic deterrence: a survivable nuclear arsenal and a largely intact maritime posture in the High North. The bastion — one million square kilometres of defended Barents Sea, shielded by Borei-A ballistic missile submarines, Yasen-M cruise missile boats armed with Zircon hypersonic missiles, layered air defence, and the Arctic base network described in the supporting paper Zashchitnyy Kupol — endures. Admiral Gorshkov fired Zircon in a live Barents Sea exercise in September 2025. The Northern Fleet's nuclear posture is not degraded. It is not distracted. It is the one element of Russian Arctic power that the war in Ukraine has left substantially intact.
