Too Many Naval Guns

The race to build the most powerful battleship was often at "logger heads" with various international treaties/agreements, that aimed to restrain the overall displacement and maximum naval gun size that could be fitted to a battleship.  This helped to give rise to three battleships that were somewhat different to others:  HMS Agincourt, IJN Fuso and USS Wyoming.

As can be seen in the above photographs, each battleship aimed to meet one requirement:  the maximum amount of fire power on the smallest possible displacement.  Agincourt had fourteen 12 inch guns in seven twin turrets.  Fuso had twelve 14 inch guns in six twin turrets.  Wyoming had twelve 12 inch guns in six twin turrets.

Unfortunately, there was a problem with such arrangements; all three battleships had to be considerably long to fit the high number of turrets in, which meant that their armour plating was "too spread out", and were often simply regarded as "floating magazines", that could explode at any moment.  Despite this, there was an advantage to a high number of turrets.  Assuming you had adequate control of the gun crews, such a battleship could engage several targets at the same time.
