Forward base, not a self-sufficient dockyard

The distinction between anchorage and dockyard is central to Scapa Flow's wartime role. Scapa could hold the Grand Fleet and even the High Seas Fleet with room to spare, but it lacked the connected maintenance infrastructure needed for rapid heavy repair and rearmament. After Jutland, damaged squadrons went to rail-linked bases where shells and repair material could arrive at scale. Even the local hospital exchanged repeated letters about shortages, showing that constructing a facility did not solve the continuing supply problem. Scapa therefore worked as a forward operating base whose fleet depended on a wider national support network.
