Iberian Empire Navy, New Designs

[Desertfox]

Some new designs I'm considering. These might need some more work to make them rule-compliant.

First the follow on to the Santisima Trinidad class, basically moves to an HMS Neptune main turret layout, and adds strengthen bulkheads (no true TB because of the side turrets).

In terms of weaponry and armor, I think the battleships work decently with what is floating or substantially constructed when they are laid down.

The 'large cruiser' misses a critical aspect of Fisher's follies. Namely that the Invincible class was meant to kill armored cruisers with 200mm guns and 150mm armor.
Here the armored cruisers of 1910 are far more similar to the Russian Rurik.  Granted the Norse Banffshire and some early 1900s ships are 155-200mm, but the older and newest are all 250mm, as are the last several Byzantium.  With 2x T2 305mm, you have slightly larger guns, but while the ACs have 180-200mm armor, you have 100..which means you can't pick long range to keep you safe.   So unlike Fisher's follies- which could take on any foreign non-battleship, you can not. Heck at a battle range of 6,000m, which is reasonable for 1909 design timeframe, the 180mm guns of the Parthian protected cruisers can shoot holes in 100mm.


On armor height - we have hindsight habits. We tend to value seakeeping more highly than the period designers, and so we have taller hulls. Which messes up classic armor heights.
- So if your freeboard is 5.8m, and your upper belt is 2.5m, and your main belt is 3.5m, does your armor cover from Freeboard down to 0.2m below sealevel, or does it start at ~1.5m below sealevel and cover to 4.5m above sealevel..and have 1.3m of unprotected upperhull ? 
It's worse on Valiente, which has a 7m freeboard and 5.7m of belts. On fire stem to stern from simple QF secondary rounds.

One of the things I tend to comment on is deck armor. The most recent Parthian builds are near 100mm, as a combo of a 65mm main armored deck and a 30mm upper armor deck, but even that would be thick for the period.  So I'm curious about how these 100mm and 110mm multiple decks are arranged, when there's no real plunging fire at the ~8,000m that is the outer combat limit when they are designed ?

another note - armored decks cap the belt, protective decks turtleback behind it, but only rise a little above the waterline. The protective decks lack reserve boyancy and restrict the machinery spaces to the waterline- but they also make it much harder to get a shot past the belt.  Cross sections of WWI ships will tend to show a protective deck as the main armored deck.

On fuel mix : This depends on your "Vision" for the Iberians, but while the Navy has 'adequate' oil, the world's merchant marine runs on coal. Right now, the navy has few overseas bases. For ships like Valiente, depending solely on oil could mean she's chained to your base infrastructure.

[Desertfox]

Well pushing the laydown date to 1915 allows the Fisher Follies to have 13.4 in guns, otherwise they are just insanely fast pre-dreads with no armor. I had the design up but my computer decided to restart before I saved it...

In summary for armor, taller belts and less deck? What would be average for the time period, 80-90 mm?

As far as oil, it looked like Olekit was moving forward to an all oil-fired navy, that's almost a necessity for the faster ships, so I was planning on keeping it. I also figure most of the newer, bigger, ships will be kept around home waters, while the older coal-fired ships will be the ones sent to the colonial possessions.

The Fisher Folly ..it's always a question of what is the design goal for that ship? 
Also, while the United Kingdom had the overwhelming largest and and strongest navy in the world and could throw money at such designs...does Iberia?

The Oil thing is just a consideration. It's going to matter in terms of foreseen roles. If the role is to be tied to your own bases, oil is fine. If the role includes going places without bases or refueling from captured merchants, then it's a problem as non-military sources might be sparse. Iberia's possessions in 1911 have very widely spaced lillypads to jump one to the other. Loose or have one blockaded, your vessels don't have the fuel to go to the next, or go back home.

Most of the British ships seemed to have a 2-2.5" main deck, and then a 1" or so upper deck.
The Parthians do their decks based on the splinters they are meant to stop- 40-50mm for 250-300mm, 65mm for 345mm+.   Then 25-30mm to cap the Upper belt.
Snip Does 50/75mm and 25mm I believe.
Some designs could have a 15-25mm splinter deck below the main armor deck to catch rivet heads and spalling.

Well pushing the laydown date to 1915 allows the Fisher Follies to have 13.4 in guns, otherwise they are just insanely fast pre-dreads with no armor. I had the design up but my computer decided to restart before I saved it...
