Iberian Place holders

Like the Norse, these are placeholders.

They will establish that that tonnage and armament combination are 'doable'.
Future players may retcon them somewhat, changing armor and speed, maybe barrel #s.
Or hopefully we will have design contests to firm these up.

The next is resident on my laptop, not my main computer for some reason.
And was labeled 'Norse cruiser'... hmm.

Anyhow, not a world beater, but the Iberians seem to go for mid-size cruisers,

The next is the light armored cruiser, to fill that gap between 'cruiser' and 'battlecruiser'
as it's a little inefficient to chase 6000ton cruisers with 30,000+ ton battlecruisers.

9000 tons proves a little tight for a 210mm ship.

The Amadis De Gaulas are meant to engage the existing 5-6" cruisers of the world,
expecting the heavier armed old ACs to fade away.

A potential "Final" version would be a 3T2 x 210mm arrangement
with a 6.2m deck aft, 100mm belt... that gives 30.1knts.
Loosing 1/4 of the firepower, armor and gaining 0.8knots does not seem...good.

There were two versions of this ship, the 23knot 33,000 and the 25knot 35,000ton.
The ship the Iberians built was 35000. Basically meant to be a fast Nevada.

...hmm where did I file that ?

Well apparently it was on my laptop too.
I think I upscaled the 23knot Lady of Arintero design, which was fresh.
Seems a decent ship.

Somewhat like a 25 knot Nevada.

This is meant to have slightly superior speed, at 25knots.
With 10 guns, even with 1910 tech it can maintain 5 gun salvos and so
garuntee the desired 4 shell ladder for best targeting.

Superior seakeeping and steadyness is a feature.

Length : Beam is a turn friendly 5.5 : 1

Armor is Good. Deck armor is thick for date, butl similar to OTL USN vessels.

TDS rises above the waterline and features a pair
of 2.5m wide fuel loaded compartment seperated by a 18mm STS
bulkhead, making a 5m deep compartment backed by a 30mm (2x15) bulkhead.

The main battery is downscaled to 8 x 400, but more powerful /50 vs /45
Deck armor is kept, speed stays the same.

Mark VI

An All-or-Nothing Design

Kalifern
Dropping the Q turret of the prior class, the limited arcs
mean most of the firepower is retained, and with the upgrade
to the 50 caliber gun, they expect nearly the same combat
effectiveness from the smaller ship.
On paper the throwwieght is 91% the same, but with the improvements in sectional density and better arcs, they expect no functional difference.

Deck Guns
Deck guns are echloned outwards, like on Iowa,
allowing 4 to bear ahead (8 guns), or 4 on each side.
The single 90m AA are above them.

Main Belt Armor
This embraces "all or nothing", but only has 1 deck level unprotected aft and 2 forward.
The main armor deck caps the belt at 1.5m.

Outsloped Wedge shaped Belt
Three steps
1) Figure adjusted height for wedge
2) figure % additional belt height for outsloping
3) apply +% to effective height of wedge.

Step 1
In the VII version, the lower portion of the belt tapers.
The upper 2.5m is a uniform 350mm, extending 0.5m below WL.
the lower 1.5m tapers from 350mm down to 310mm.

Mathwise that means there are 3 sections.
| |
| | A ) Upper, 2500mm (2.5m) x 350mm
\ | |
\| | C) Lower back , 1500 (1.5m) x 310mm
B) Wedge 1/2B x H :
B = 1.5m = 1500
H = 350-310 = 40

A) = 875,000
B) = 30,000
C) = 465,000

SubTotal : 1,370,000
Modeled as average 350mm thickness = /350
Total : 3,914.27857 = 3.91m

Belt is slightly outsloped by 15%.
Step 2 Outsloping
Overall it is 4m high. which is "A" or adjacent
COS 10 = A/H
H* Cos 15 = A
H = A/Cos 15

Which gives 4.1411or 4.15 as the height.
4.141 / 4 = 1.03425

Step 3, applying the outsloping mod to the effective belt height
This is 1.034% more height than the standard 4m non-wedge shaped.
The effective height of the wedge shaped 4m belt is 3.91m of 350mm
So 1.034 * 3.91 = 4.04294m = 4.04

What if I had rounded up?
1.035 * 3.92 = 4.0572 = 4.06

All of which 'saved' only about 80 tons.

Deck Armor
Deck Armored is modeled as two parts
A 35/135/100 main armored deck : 4853 tons
and a 35mm box around the magazines : 133 tons
Which is a total of 4986 tons

To model that, the deck thickness is shown as
35 / 139.2 /100
Which weighs 4988t

Which means vertical is a 135mm deck with a 35mm splinter box over the magazines.

Like most 'all or nothing' the Forecastle and Quarterdeck sections
are set up as protective decks.

TDS
Raised to the underside of the Armor deck at 1.5m above waterline.

TDS : Bulge ||9mm mild hull||, 1m liquid ||9mm mild||, 1m void ||9mm armor||, 1m liquid || armored (2x19=38mm)||,1.5m Dam control/ flooding ||(9mm mild)||
Depth : 1.5m exterior, 3m interior to main bulkhead, 1.5m to second bulkhead. Total :6m, 57mm STS steel

There is a 35mm Box around the magazines this adds 130 tons,
boosting total deck to 4574

oops 2 tons over.
Numerous ways to fix that.
Close enough for this 'Placeholder' purpose.

I should have done a 6x 105 ship, but I was working off a Parthian 120mm design,
as the Iberian requirements are likely closer to Parthia than most nations.

Simply swapping in 6x105 with Deck mounts is doable strait across...
hmm easy fixes.....

   Ship has slow, easy roll, a good, steady gun platform
   Good seaboat, rides out heavy weather easily

Adapted from a draft Parthian Palang destroyer,
the Iberian needs are similar - great range for escorting between widely scattered bases.

The 80 preceeding DDs, led by the 18 "F" class can operate in 12-ship cells (5+1) for shore based operations.

The G class would be the larger, fleet escort, DD.
The addition of ASW roles means they need to move around the fleet, which means a 2-3 knot cruise speed bonus over the main battleline. So 14-15 knots.

The longest stretch seems to be Durban to Port Moseby at ~6800nm. Diverting to the Molucca is another 1500nm.
...its just not doable. So they try to get close and assume mid-Indian ocean will be at a straight line 12knots.

476t of oil fuel will drive the ship at 12 knots for 7900nm
476t of oil fuel will drive the ship at 31 knots for 660nm (21hrs)

The high freeboard both means better operations in the pacific, and more accomodation room, so the crew is not completely
worn out by a couple weeks at sea.

A successor to the placeholder 1918 G class.
A shorted, but stronger hull allows
slightly higher speed and more misc wt.

This introduces the 1920 ASW,
with basic sonar and DC throwers.
and enhances the DC loadout

There is slightly more range,
but sacrifices the better seakeeping of the G model
at top speed.

Accomodation room is still excellent
but the more crammed hull has less floatation.

The Iberians really need an AA gun less than 90mm.
