Well, aren´t 6x6" too weak to be an effective secondary battery?

Bulges of 2m only? Why?

Very heavy third and forth battery. Will there also be 20mm guns?

Personally I think her deck could be thicker. Or are you using Gavin´s formula to calculate actual deck thickness?

Isn´t her bc a little low?

Her range is excessive. That´s really a lot, methinks. Are there escorts at hand that can keep up with her? Or is this fuel meant to lower her displacement?

Her face plates are really thick but her belt seems to be lacking. Wouldn´t it make sense to transfer some armor to her sides?

I agree on some points, she could IMO use some more 5.98" turrets amidships. I'd personally drop a knot speed to get more armor as 28 knots is still respectable.

Given shes a Pacific bound warship the range doesn't seem odd to me, even if it is to keep her standard displacement down at 35,000 tons.

She's to fulfill the concept I laid out a while ago with the Paris class BCs, to do long runs at high speed in order to show up where she's not expected. Her BC's low because she's got a long forecastle before she really fills out.

And as for her belt, its not so bad for operations in the Pacific, where 15" guns are pretty rare.

Her turret faces are thick because I intend to point the two of them at the enemy, in line abreast at full speed, guns blazing.

The ship is a powerfull warship and can take on any thing currently in wesworld.(beside Rooijen secret projects)
but i have to agree with the secondary being to light

The Pacific is not filled with 15 inch guns....yet. Plus there are those rumors about 16, 17, and even 18 inch guns projected in the region. Also the 14 inch guns are nothing sneeze at really.

But these French ships will do.

Its French for Scheer's order to First Scouting Squadron at Jutland.

But these ships are built for that sort of thing.

The Cb is far too low for such a short and beamy vessel. 0,55-56 is more normal.

6x152mm guns is inadequate. Add two beam mounts abreast the superstructure like Clemençeau.

http://xoomer.virgilio.it/bk/NWS/Marine_…gne__2C6F3.html

Thicknesses of deck armour. 135mm is fine even if it is just a single thickness plate over all the hull. It won't be penetrated at any reasonable range by gunfire.

Aren't the end belts really inadequate? 30mm probably won't stop anything and 2m high nothing will actually hit it.

Secret projects? What on earth are you talking about?? I know absolutely nothing about secret projects!

(I assume that with 'secret projects' you are referring to the mysterious 'Izumo no Okuni' entry in Japan's encyclopedia)

I think it is fair to compare your latest design to the historical RICHELIEU-class BBs designed by France in the late 1930s. Hence I looked up my Garzke & Dulin "Allied Battleships of World War II" for information about the RICHELIEU-class hull form.

On page 140 the authors state that the class had a fine hull form with a coefficient of 0,58 "which gave excellent speed performance, with very god resistance factors for high speeds."

RICHELIEU, designed for 30+kn, was doing 32,6kn in June 1940 during trials according to G&D......just to give our WesWorld speed nerds something to think about. :o) You don´t need a cruiser like BC for a fast capital unit.

Hmmm... 32,6 knots.

What does this source give as her dimensions (waterline and bulges for the beam) and normal and standard displacement? I've had some difficulty reconciling the displacements given by the sources I've been able to find.

242 x 33.08 x 9.17 is what I have from armour cross-sections.

G&D gives

Standard displacement 37,832 tons (38,450 mt)
Full-load displacement 44,708 tons (45,438 mt)

Waterline length 794` (242m)
Waterline beam 108,53` (33,08m)
Draft (design) 30,09` (9,17m)

Displacement figures are based on the 1940 Weight REport of the RICHELIEU.

Whitley's states the same demensions except it states the draft as 31 ft 9 in/9.63m mean .

And how big were her bulges?

About 35.2m after she was reconstructed.

So she should be something like this;

Provence class battleships Provence and Bretagne will begin rebuilding in 1931. There will be improvements to deck protection, small bulges to support her increased deck armor, and improve her stability and underwater protection, a new secondary and AA battery, reshaping the bow, engine/boiler replacement, conversion from coal to oil firing, and increased fuel bunkerage. Her torpedo tubes and end belts will be removed. The rebuilding is expected to last about 15 months.

Upon completion of the Richelieu class, MN Lorraine will be converted to a gunnery training ship, and present training ship Courbet class battleship Jean Bart will be scrapped.
