Standardised armament and cruiser numbers

Using a common secondary and destroyer gun calibre across a fleet has appealing logistical simplicity, although the designs discussed usually separate destroyer, cruiser, and capital-ship weapons. The fleet tends to use two destroyer types while repeating one cruiser pattern with roughly twelve guns in four triple turrets. The standard cruiser's value comes from producing it in large numbers and bringing several ships against each enemy squadron. Standardisation links supply and production directly to the strategy of fleet concentration.
