Why capital-ship dry docks mattered more by location than ratio

Capital-ship support depended on which ships a dock could take and where repairs could be made, with floating docks adding movable capacity.

Question

What were the dry-dock-to-capital-ship ratios of the major navies in the Second World War?

Short answer

A simple ratio is misleading; dock dimensions and, above all, their location relative to likely operations determined whether they could sustain capital ships.

Notes

Counting docks by navy conceals whether a particular capital ship can fit and whether the facility is near the theater where damage will occur. The Royal Navy catalogued facilities across Britain, the empire, neutral states, and potential belligerents because wartime access could change. Floating dry docks offered a cheaper way to move repair capacity forward and helped reveal which permanent yards warranted later expansion. Concentrating floating docks near a potential theater could signal readiness to absorb losses and restore damaged ships to service. American floating docks likewise made advanced Pacific bases practical and allowed damaged ships to be regenerated without returning to the continental coast.
