The Bermuda compatibility chart turns overseas dock dimensions into a design argument for an interwar 20,000-ton heavy cruiser. Existing stations could maintain ships around that size at many points across the imperial network. A 40,000-ton capital ship demanded much larger fixed or floating facilities, sharply reducing the places where it could be sustained. A heavy cruiser would therefore have offered the Royal Navy considerable global utility during the treaty era. The value of a warship type depends on combat performance and on how widely its support infrastructure is distributed.

The global dock network favoured a 20,000-ton heavy cruiser
A 20,000-ton cruiser could use many more overseas facilities than a 40,000-ton capital ship, turning maintainability into global utility.
