Yes, much.

She has the German trend of a separate Secondary Battery/Heavy AA Battery which cost space but that's a deliberate design decision. You might want to try a version with a true DP Battery, this will save you much weight which can be used for other things like thickening armor...

Your designs are getting better, looking forward to more! :D

Re Jormungand,

I would compare your numbers to the real Admiral Hipper-class as the closest comparison, your numbers are a bit high considering that they are not much bigger.

I would ditch the TDS its just to small to stop much and most CAs didn't have one.
Beam between torpedo bulkheads 16.76 m and beam of 24.00 m gives you 3.62m each side not sure that will do anything but act a a wing tank (on opposite undamaged side) and capsize you after a hit.
(this will save you loads of length and weight and you can go to unit BR/ER/BR/ER to save you from one hit)

Not sure why you have 6" guns on a 8" CA rather than more 8" ?

2nd: 5.00" / 127 mm 3.00" / 76 mm -
3rd: 2.00" / 51 mm 1.00" / 25 mm -
4th: 2.00" / 51 mm 1.00" / 25 mm -
Forecastle: 3.00" / 76 mm Quarter deck: 3.00" / 76 mm
All a bit strong don't you think ?

30.00 kts is slow for a CA you should be able to outrun BCs or you will die.

Maybe design it with automatic DPs given the German quality obsession?

@ 6" guns: the German design philosophy is odd to those who see DP guns everywhere. From what I can tell the lack of DP guns is due to the mentality that Germans had in general towards DP guns in that they're too much of a compromise in the first place, so they worked on getting a space-hogging arrangement of AA and anti-ship guns to work instead.

@ TDS: was going to have 5" torpedo belts but someone suggested to half that.

@ more 8" guns: see the reasoning for the 6" guns.

while it may look good on paper, you try drawing that with all the weaponry you have given it, and in the places you have said they are to go. The ship just is not big enough to take it. Which is why I hate Springsharp and wont use it. It gives too many false reports and lets ships like yours into the water where they just do not work (except on paper).

Below is a blank German cruiser 704x80 feet, close enough to your dimensions. Below it are the gun and torpedo types you have nominated. Try and fit your armament on both upper and lower views.
Post the result back into this thread so we can see what you can come up with.

Alright then, I've downloaded the blank ship and will get something in the coming days.

Wish that Springsharp continued instead of dying though...

Good luck with the fittings, you also have to remember with the 6" and 8" they will need to have ammunition handling rooms and magazines underneath the turrets, and then you still have to do your machinery rooms.

Hi GrandAdmiralFox,

As I understand it, one of the big drivers towards a separate low-angle battery was concern over RN destroyers - the KM traded away AA performance to ensure they'd be able to engage destroyers outside of their own range. The 105mm AA followed on from the 149.1mm's manifest unsuitability for AA work - if you're going to have to carry separate AA anyway, might as well optimise it for that role.

Regards,
Adam

But this isn't a Capital ship no 8" CA (even the German ones) had a secondary battery and only had DP or AA guns as secondary.

8" are perfectly good at shooting at DDs so why not just have more of them and save having to ship twice the directors etc...

Looking at this I see a raider or an escort. Main Battery isn't enough to take on a capitol ship but she can take on most anything else.

I do agree that deck space is going to be a bit crowded with this many guns though...
