For 1924

[Borys]

Ahoj!
My building plans for battleships are:
1920 - two ships with 4x4x13"
1922 - two ships with 4x2x16,25"
1924 - two ships with 3x4x15"

[The Rock Doctor]

Why are you going from 13" to 16.25" and then down to 15" again?

[Borys]

Ahoj!
I'm afraid 42cm quads are too big ...
The twelve 15" give me a heavier broadside than the eight sixteen-and-a-quarter inch guns.
But I'll see what I can do with twelve 16,5" guns ...
Borys

[TexanCowboy]

The CSA plans for 1920....well, at least while I was there, I have no idea what Carthiginian has planned, were two fast battleships,(Same armour as preceeding class, but 27 knots), and with 9x16.5'' guns.

The 7.5" secondary and 6" tertiary batteries is decidedly retro. Wouldn't there be some concerns about effective fire control there?

[Carthaginian]

The CSA is looking at something in this general size range... probably a knot or so slower than their contemporaries (as Confederate battleships generally are) but much more heavily armored and similarly armed.

Slower... as if 28 knots isnt slow enough...

...28 knots is slow?

I'm surrounded by crazy people. Out, out, foul ghost of Fisher!

It is when I want to go 30 =P and im not Fisher, I dont want to build his BCs I want to build Iowa LOL

Now, I need a Type 4 slip for this ...

ACK GAG RUNS TO HIDE (Quads are EVIL even if I to have a few ideas that would make use of them)

[Carthaginian]

She might need to be a touch broader in the beam, Boris- the South Dakota was only about that wide (108'), and her 3x16" turrets are almost cramped- especially forward. I'd imagine that your ship simply is simply NEDS. ;)
