Anybody think this is worth building?

I'll need to do some research, but late 1914 lay down shouldn't be a problem.

Ahoj!
Interesting ...
Fine looking ship (I love en echelon turrets! :))

In your strategic position it is IMO a good ship. It can chase down and destroy practically any cruiser there is. Smaller cruisers with 27-28kn top speed would have problems in running away.
But maybe an overkill? Maybe 5x2x9-10" with 400-500lbs shells would be enough?

You are not likely to slug it out with ships with belts thicker than 5" or 6".  Armoured cruisers, even if with a belt (slightly) thicker than that, would still be smashed by your guns.

It goes against my design principles, but a tin clad with 6" or 7" coverage of maximum hull area would probably serve you best against 5-6 inch shells from enemy smaller cruisers, and the occasional 8-9" shell.

Or maybe go to the other side - with fewer but REAL guns :)

Very nice design Borys. I like it. I may go w/ the 9.2"/45cal instead, should lower the weight a little more. Only a 400lbs shell though, maybe to small? It would save me from having to develop the 11"/45cal though. Hmmmmm..... Also, what do you think of the internal layout? Does it look OK?


The latest one, w/ the 13.5"s is more or less a poorly armoured BB, don't you think?  ;)

[Borys]

Ahoj!
As the French and Austrians had 240mm guns firing 475-485 shells, I'd assume that 450lbs shels for a 234mm weapon are fully feasable.

I managed to squeeze one more knot out of the lighter gunned design, if you look closely :)

Inner layout looks OK to me, but I'm no expert.

The 343mm design is a heavy cruiser. Very heavy ...
Borys

[Jefgte]

Nice & interresting studies
Fast & stronger cruisers abble to kill every old armored cruisers.

Jef  ;)

[Borys]

Ahoj!
Austria has 11"/40cal guns. Maybe a bit dated, but adequate for the job ...
Here I am using the OTL KM guns, with very light shell - 520 lbs.
Far cry from the Swedish 672lbs shells.

An interesting artifact of SS2 - first sim a ship with 10" guns and 520 lbs guns. Then change the guns to 11", but keep the shell weight as it was. Watch the keel break :)

Borys

[P3D]

I'd say 8-10x11" with 27kts (on a longer and leaner hull) would be the best.

I found that in N-verse we have such an even distribution of designs that almost any design would fit nicely between two others.

[Korpen]

I'll need to do some research, but late 1914 lay down shouldn't be a problem.

The armour scheme as presented in the drawing worries my quite allot, it seems perfectly possible (even likely) for a shell to reach the vitals after only penetrating the 127mm upper belt. This is a feat that even 20cm guns can do at quite decent ranges.

Moving the main deck down to main belt height would help allot there.

Also worried about the thinkess of the TB, just 25mm is really low, and quite likley to fail if put to the test, I think 35-45 is the ideal, and less then 30 might do more harm then good.

Ahoj!

Well the Swedish gun was a L45, and its shells were just 3kg heavier then those used in the German L45;s.

[Borys]

Ahoj!
Yes, indeed about the Swedish shell.
The move from 40 to 45 calibres was linked with a move from 529 to 666 lbs shells.
I've got the shorter gun.
But as the idea is to kill cruisers, not battleships, it should/could suffice.
However, if combined with top-of-the-art FC, this ship could be a threat to PDNs.

My lighter gunned suggestion improved the original armour scheme a bit:
- TDS belt is 1,5";
- MB reaches one foot higher;
- UB is 1" thicker;
- end belts are 1" thicker;

This was at the cost of decreasing MG calibre, of course.
If the 11" are kept, not sure if there is enogh reserve in the design to thicken the armour.

I image does not have the true freeboard from the SS report, but simply included to show the general layout.
Note that the armour goes from waterline (and 2m below) to the top of the sides.

Thanks for the input guys. I also have an 11"/40cal, w/ a 650lbs shell, so I'll use it. Added an inch to the upper belt and the casemates, then moved the armored deck down to the top of the main belt.

Ahoj!
You know what, guys?
I really can't say which I like better. I like them both :D

Would it be worth ditching the torpedoes any using that weight to increase armor?
