A 12,000-ton Tiger cruiser needs more than four 6-inch guns

What are the disadvantages of 10,000- to 12,000-ton Tiger-class cruisers?

At that displacement, four 6-inch guns are too little; the ship must use its size for a much heavier automatic gun battery.

The main disadvantage is underusing the ship's size. A 12,000-ton cruiser carrying only four 6-inch guns would be conspicuously under-armed. A credible version would need a much denser battery, such as eight automatic 6-inch guns and eight 3-inch guns. Displacement creates expectations about the combat system a design should carry.
