Now I just have to figure out how to afford it. I'll have the Tech by 2HY/1913 at the earliest, 1HY1914 at the latest, so that's not the problem, it's that 5-5.5BP/HY problem. Anybody have extra BP, a type 2 dock/slip, and an interest in $$?

I'd reckon it's 4.258 BP per half-year if evenly spread over the life of construction.

I'll consult my spreadsheet tonight to see what GC's BP situation looks like, but am not optimistic that I could dig up that much.  Finding a slip to build on wouldn't be a problem, though.

Nice BB, Well balanced

How many HY to built this Ship?

Actualy in my Board program, I have a 170m slipway at Callao free from 1914H1 to 1916H2 - 6xHY in all.

22 months+9months=31 months=5 HY

Jefgte

He could take more time...
6HY or 7HY & built regulary a BB.
With 8HY, He could built other warships in parallel.

Niiiiiiice. I'd try to identify the OTL counterpart, but I've spend so much time looking at and thinking about Cross Mirage that she's the only thing that comes to mind with that layout.

Here's the full view w/ the hull and full depth of the belts.

Image based on parts by Wes Wilson, modified by me.

Any more guesses on the origin of the idea/basis for the layout? Here's a hint: She would have been built on the Atlantic seaboard in the 1910's.

Slightly updated SS Report w/ the belt extended 2' fore and aft to extend slightly beyond the "A" and "Y" turrets. Also the TDS is a little shorter, without lowering the "Torpedo hits to sink" value. I increase the amount of oil fuel as well to 40% from 10%. For those of you wondering why I went back to partial coal firing the answer is simple, I only get oil from 1 country, and that country wasn't terribly happy w/ The Southern Cross Alliance. (At least the former player wasn't, don't know what the new guy will think.)

Partial use of coal is reasonable but bear in mind that you're now allied to another nation with growing petroleum exports...

You could also try building a native coal liquification industry, as I've done.

I Like the BB Nice design.

Hmmm... I will have to go read that thread on Oil because unless It gets found in Libya - Italian North Africa/Tunisia much sooner then in real life I am surely out of luck.... Wonders if Romania sells cheap and if I can get ships their now with the war going on.....
