Ahem.... The Reformist China's studies into large ships. These ships are only written down on paper. No real effort has been made to convince the Repbulican Sector of building these ships, although that might change.

[Walter]

Well...

Main belt does not fully cover magazines and engineering spac

and

79.00 ft / 24.08 m Unarmoured ends

Maybe the result of you altering the hull form?

[Logi]

Yea, I forgot to modify the armour after I changed the hull form. Here's the corrected one.

[P3D]

The vertical protection is more or less useless against main caliber shells.

[Tanthalas]

The vertical protection is more or less useless against main caliber shells.

I think its suposed to be for reduction of a NS Battlecruiser to scrap (my Mk1s also mount an 8" upper belt and 12" main belt)

[The Rock Doctor]

Logi, the freeboard is a good two metres higher than necessary.  Drop it to somewhere between six and seven metres and you should have decent seakeeping, while freeing up considerable hull strength for use in upgrading protection.

Six inch and five inch batteries are unnecessary if both used for anti-surface work - go for a single caliber, and avoid "broadside" mounts. 

You have about ten times more anti-aircraft guns than is warranted for the period.

What would it cost to build the port/slip/dock facilities necessary to support this vessel?

[Logi]

@ TRD
As such that Macau is a Type 3 Port, it would take $15 and 1 BP to upgrade it to Port 4.
Macau has a Type 3 Drydock, requiring $6 and 1 BP to upgrade it to a Type 4 Drydock.

So all in all, China would need to spend $21 and 2 BP to builkd the ports/dock facilities necessary to support this vessel.

@P3D
I have no clue how to calculate sloped armour. I admit your point though. Prehaps you could show me how one might go about designing a ship with sloped armour?

@Tan
This ship was really a design in attempt to see how the 16"/42 guns would work on a ship since the guns would be completed in 2~3 years. I was not acutally thinking of any ship while designing it except for the French Ultra BB and the Baltic BC (I used them as guidelines). It just so happens that I split the armour like you ;). Now if it were to be built, I would have to take a look at comtemporary NS ships.

[P3D]

To calculate sloped armor weight, the thickness have to be divided by cos(inclination). A 13" plate  inclined at 10* has the equivalent LOS thickness of 13.2".

Inclined armor and bulges means that a significant portion of the ship's buoyancy is vulnerable even to 6" hits.

Average freeboard should be ~21-22. Let the freeboard be 20'. With 8' decks you need 4' to the waterline and another 6-8' below - but that's too little so you might want to extend protection upward. So 19' belt armor is reasonable. However, in this case, you need no upper belt, especially as you have no casemated guns.

Forget end belt and the 3 different small-caliber guns.

The ship has a 15" belt inclined at 25 degrees.

[P3D]

You might want to sketch the cross-section of the ship to see if it is possible. The only problem with 25* inclination that you ship might sink without any penetrating hit due to the flooding of one side. Also, making 18" face hardened armor is IMO more than what RRC is capable of.

[Logi]

I didn't think 25 degrees inclination was that big a problem. If need to be, I'll fix it to 20 degrees.

For the 18" face hardened armour - its acutally 15" armour after an inclination of 25 degrees. It is shown as 18" just to show the weight of such armour. Unless I read your passage about inclined armour wrong?

[P3D]

Limit inclination to 15*, or if the plate is really so high, then to 10*. Deck armor is marginal.

[Logi]

ah, then 15 dgrees it is.
