What quad 6-inch turrets would mean for Belfast

What if the Royal Navy had quad 6-inch turrets ready for Belfast?

A 16-gun Belfast would have exceptional cruiser firepower, trading some rate of fire for a broadside that could overwhelm many 8-inch-gun opponents.

The Colonies were designed around three turrets and twelve guns, so the alternative changes the cruiser rather than completing a missing fourth mount. Quad mounts would fire somewhat more slowly than twin or triple arrangements, but their numerical advantage remains formidable against contemporary heavy cruisers. Belfast and Edinburgh could deliver sixteen 6-inch shells per broadside against opponents commonly carrying eight or nine 8-inch guns. The comparison shows how the Royal Navy's preference for volume of fire could compensate for the lighter individual shell.
