Re: [FT] Weapons Cost for firing every other turn

The French four gun turreted battleships and
battlecruisers actually
Had armor that separated the turret into 2 by 2 guns.
I have no idea
of the layout of the British King George V four gun
turrets.

Disagree with you on this one. As guns got bigger the
technology
of the turret fell behind. The casement (1865 onward)
allowed
 for bigger guns on a ship but it was dropped as soon
as
 turret technology caught up due to:
-the need for overhead cover (plunging fire) as some
navies
 used open casements to maximize elevation (range)
-can bring all guns in turret on target (sort of your
answer)
 as opposed to one gun per casement
Note that I am referring to the primary guns on the
battleships.
Secondary guns on battleships and on some Cruisers 
were
casemented as late as the 1920’s.
