The ships as such are fine; but II will be boring and question the concept.
You said you are lacking BBs; do you not then feel that building a single huge BB that will use up a majority of your BPs for the next three years is putting a lot of eggs in a single basket?

You can get a decent small BB at about half the size, especially considering that there is not allot of first rate BBs in Asia, an even a small BB can give allot of the battlecruisers in Asia a run for their money in a stand up fight.

Lack of TDS considering the opposition (MK TBs and DDs) is not a good idea IMHO.

strange freeboard for the stern  ???

------------------

Peru had also small BBs designs

- Panzerschiffs Jef ?

- Yes but stronger & with BB protection.

:D  :D  :D

A different version of the Peace Class BB
NOT a practical design, a design for future BBs...

Originally I had planned to use sloped belts but decided against it (too much work). The ship is shaped like US Battleships - winebottle. The unique shape is reflected in the quarterdeck, midbreak, and forecastle percentages.

Like Mike's ship, this BB uses multiple FCS. The exception is that it is two BB FCS control the turrents aft and forward. There is only one Cruiser FCS controlling the secondary battery.

[P3D]

The big one is underwhelming - I can get 29kts, 12x13.5" on like 35000t.
The second-class BB stands no chance due to weak armor.

You need ships like Korpen suggested, but with TDS - 8x33cm 21kts on 16-18000t. Fast BBs might be too much of a luxury for RRC.

[Logi]

The advice on TDS is noted, but what do you mean by 'fast' battleships?

The battleline speed for the RRC is 24kts. By all means these battleships are standard speed.

[P3D]

Where can I find post about which BB designs are getting built?

[Tanthalas]

Where can I find post about which BB designs are getting built?

He hasnt built any yet... He decided that his fleet speed should be 24 knots (still not sure why)

[Logi]

Well as Tan said....

6", 5" AND 4" weapons?  42 such weapons?  If any ship is at risk to a secondary explosion its this one.  We won't even go into where all would be fit...

I STRONGLY suggest that you trim things back some.  It should free enough displacement to get superfiring on one or more of the 13" weapons.

[Logi]

In my own drawing, its all clutered on the superstructure, probably not the best idea...

I STRONGLY suggest that you trim things back some.  It should free enough displacement to get superfiring on one or more of the 13" weapons.

I will trim them back. However, I don't need to get superfiring on the 13" turrets, there are only two! They are quad 13"s

[Jefgte]

I agree, too much & various secondary guns also too much protection for them

- 2 x quad turrets I presume (?)

- Main belt is short
