Peruvian pocket Battleship

[asavery]

Yet another first cut for my initial fleet.  I'll probably only have one or two to start with, but would be state-of-the-art.  Not intended to be the biggest or baddest on the block, but be fast with a decent punch and protection.  I was aiming for a <18K full displacement design.  Comments/suggestion?

Ahoj!
Needs a little work. I suggest trading "fire platform" for stability. 1,10 should be minimum considered for a vessel that is planned to take damage when slugging it out.

Ahoj!
I have to admit I find the Contitution superior. That 1,500 tonnes difference was put to good use by the Swiss. Buy Swiss design for 2$?
Borys

[Borys]

Ahoj!
Hmm, looking at the armour, the Swiss ship is closer to an armoured cruiser than battleship. Whereas the Peruvian ship is nicely armoured.
Now, it is up to you, to go the OTL route of South American warships - overgunned and underarmoured (here with bonus of grat seaworthiness and speed). Or cut back speed to 21-22 knots and invest in seaeeping.

Both routes are viable.

The Swiss ship allows Peru to catch (!) raiding cruisers off its shores.

Borys

[Tanthalas]

or you could just modify my 10" cruisers.  (and they have the added benifit of being CHEAP)

[P3D]

For building, we consider light displacement. Armor deck should be around 2", I'd also try to get one more knot out of the 48000SHP available.

Trim is excessive, I usually try to have it between 40 and 60.
The 8"s should be in twin turrets on barbettes.
I'd aim for a length:beam ratio of 7:1 for a 24-25kts ship. That would also help with SHP.
Main length should also increased to cover machinery and engineering spaces. Belt height also increased to 12-13' looking at the current freeboard. Keep the upper belt at 8", that's a usual distance for the one deck height the upper belt should cover.

The ship that way might be a bit huge for your small capacity. Keeping 24kts speed would help keep the cost down.

[The Rock Doctor]

The original design could, if necessary, go toe-to-toe with a semi-dread or pre-dread and possibly win.  Connie's armor lacks a bit in that respect, and the Italian cruisers aren't up to that task.  

I'd add more miscellaneous weight than you have, asavery:  as the largest ships in you fleet, you'll want wireless, flag facilities, torpedo weight, a growth margin, and maybe stuff like VIP quarters.  

[Desertfox]

Actually the Constitutions have withstood battledamage quite well. Constitution herself came whitin an inch of blowing up Schanhorts. Only bad luck allowed Schanhorts to escape.

[Borys]

Ahoj!
The default setting - 150 main calibre shells, is appropriate for cruisers. It is too high for battleships. Here, 80-120 is the suitable range.

The Command Tower should be 12 inches too. We can't get the admiral killed, can we?

I consider End Belts thicker than 4 inches to be a waste of steel, but that may be only me.

Main Gun barbettes should be 9 inches minimum, 10 inches is still skimpish, 11 inches is adequate, 12 inches best.

Cruising speed 15 knots is not approprate for this era. Please set 10 or 12.

Stability, Fireplatform, Seakeeping - I consider the mix to be OK .

Borys

[P3D]

Cut speed to 24.00 knots.

I calculate effective barbette thickness as barbette+Upper belt/2 if the cover is adequate. Increase  main belt height to 12'. Cut torpedo bulkhead thickness to 1.5".

Ok, trying again...  with the exception ot the caliber mentioned by Boyrs, I think I have addressed most of the comments...

Back to the battleship.

IMO get range up to 6000-8000@12. Increase draught by 2'. That would decrease cost a bit.

Cruiser: Use turrets on barbettes, and less armor.
