MIND THE GAP VII — OPERATIONAL ARCHITECTURE OF THE HIGH NORTH: THE THEATRE AS IT STANDS
UK Defence Forum High North Observatory By Robin Ashby, Director General UK Defence Forum; Rapporteur, High North Observatory
The preceding papers in this series have established the historical baseline, the decades of Western strategic amnesia, Russia's systematic rebuilding of its northern military power, the transformation of the Arctic as an operational environment, and the accelerating Allied response. This paper draws those strands together into a single assessment of the High North theatre as it actually stands in the spring of 2026 — not as it was designed to look, not as declared policy describes it, but as the operational balance of capability, vulnerability and risk that any honest strategic assessment must confront.
The central finding is not comfortable for either side. Russia has degraded its own conventional Arctic capability severely through the war in Ukraine, creating a window of Western advantage that did not exist three years ago. But the Western response, while accelerating rapidly in command architecture and procurement commitments, has not yet translated those commitments into deployed capability at the scale the theatre demands. The window is open. It will not remain open indefinitely.
The 67th edition of the Military Balance was launched at the London based International Institute for Strategic Studies on 24th February, the 4th anniversary of the start of the Russia – Ukraine conflict. Nick Watts was there for Defence Viewpoints. He writes: This was a sobering backdrop against which to be considering the current military – strategic environment.
