Why the fleet left, and what Scapa Flow still does

The Cold War did not erase Scapa Flow's northern relevance immediately, but the costs of supporting a shrinking, more complex fleet became increasingly hard to justify. Today the sheltered water supports energy logistics, including ship-to-ship transfers that break cargoes from very large tankers into vessels able to enter smaller ports. Maps of the A9 and A836 underline how little road capacity exists for supplying a major base, even before the need for new island links is considered. The future case remains conditional: a major northern fleet could use Scapa as a forward operating base, but transport and support limitations still rule out an easy return to a complete dockyard complex.
