I'm all for introducing things to the game that will improve the gameplay, strategy, etc.... What I'm saying is that we have enough trouble dealing with the 8" gun CAs.
So instead of dealing with an 8" gun ship we now have to deal with a 16" gun ship, capable of doing even greater amounts of damage, from considerably farther away? If you take into consideration firing at anything beyond the range of the existing optics, that means revamping the graphics to see the target beyond the ranges we currently have. Or, it means developing a radar-directed fire control system, which would be a completely new development to the game, unless you adapt the land mode we currently use to blind fire at a square on the map.
A 16" gun strike to a CV would effectively kill it, one shot.
And don't base it on the premise that a 16" round is twice as deadly as an 8" round. They're not. If I were to do the math, I'd figure somewhere in the range of 20-25 times more lethal when you consider ballastics, trajectory, penetration data, etc. Iowa throws a shell that weighs 2700lbs. The average 8" shell is somewhere in the range of 85-100lbs depending on the type. A broadside from an Iowa is 17,600lbs of shell. How many pounds of bombs does it take to kill a CV?
Ya see where I'm coming from?
