While attempting to procure 38cm/L45 rifles for future projects this design was floated around to consider the use of these weapons.

Do you really need the 105s and the 150s? It seems like the lesser caliber will just complicate secondary battery fire control.
I love the classic Kaiserliche Marine color scheme.
As do I :D
I fine no problems with the 105s and 150s: Its the 105s and 88s that bother me. Too close in caliber to make much of a difference (would be a whole different thing if they are meant to be AA guns).
Also the TDS is a little thick, I would have gone for more deck first but that's just me. The range is quite tiny... 6000nm at 12 kts? I have 8000nm at 12kts as standard range and even I'm rethinking it.
But overall nice ship and good firepower.
God thats alot of secondaries...
Michael
Sorry - tough as old boots and worthy but ... dull
Seems more an expansion of the past than beginning of a future
Agree - range is very short - for home waters only?
Speed - step in the right direction - but short focsle, no breakwater (?) and lack of sheer forward means problems in actually using the speed except in light seas
Would also mean poor visibility in fwd turrets and the low bridge
105s - I think too light for future, and overall too many secrys + tertrys for BB.
8 x 15s, heavy armour (but can you reliably produce 15" armour of good quality?) and the wide TDS - the best aspects I think
Seems a substantial investment - isn't GBP5.6m capable of delivering more?
Mentat - just ignore whatever price SS2 gives.
The number of secondaries are important as several possible opponents of the DKB are strong on light forces.
7.3m freeboard is high enough for me.
The 88's are apparently AA, while the 105s are anti-TB.

------
Seaboat quality is not very good...
;)
Isn't the SS2 price the basis for resource allocation - have I got that wrong?
Overall freeboard is fine - but concern is about the short focsle and lack of sheer at the bow - the design at the front looks weatherly enough for 18-20 knots but not so good for 25
DKB's had a love for large secondaries for a while - look at S&G. When you consider the light forces fielded by some of its neighbours - and its experience in the Second Pacific War - I think it's not unreasonable to continue the trend.
Yes the 88s are for anti-balloon work...I forgot to change them. As the ONLY nation to ever be attacked by things that go bump in the sky I though a relatively heavy (IMO..some designs here have WAY TO MANY AA guns) would make sense. As for the 15cm, 10cm issue..P3D is right. NS, OR, and Italy all have mass TB/DDs and are possible opponents. As is Maoria..but they have almost NO TB/DDs. My personal though is that the 15cm are kinda slow firing, but the 10cm lack the oomph necessary to stop a DD. I'll be starting research into a 12 or 13cm gun in 2/16 and may use it instead w/ the standard 16 in the hull(although if you note they're practically 'deck' level w/ the quarterdeck) and probably develop a deck mount and put 4 per side in though on deck level. I'm sure I'll discover that the 88s are piss poor AA guns and ditch them eventually, but that will require 'experience' that we don't have yet. As to the lack of sheer, I suck at putting sheer in my drawing, hence I subconsciously avoid it in my designs. I'll see how it works w/ some sheer and the 'future' 12-13cm guns. As to TDS vs deck armor. 75mm will stop most if not all current and many future guns at the ranges battle is fought at now, and will hold up in the future. 10cm is enough to stop ANYTHING short of AP Bombs, which aren't an issue ATM and I don't like hindsightitis. The TDS is not too think, IMO, but I could go w/ 50mm if the consensus is that it's thick enough.
Actually, I did have a small issue with airships at one point, but they ended up being less destructive than the ones DKB dealt with.
I agree that some vessels out there are somewhat over-armed with AA guns
Here is the one w/ the 88s as AA and the 12cm secondary. I also *gulp* put a clipper bow on it and some sheer in the f'cst'le. I also upped the range to 8000 @ 12kts. I had to increase the beam to get a steadiness over 49 though.

1kts is barely a margin over my cruisers, the ship is outgunned by the Dutch ships or my BCs, light secondaries means two or three destroyer squadrons could surround her. But she's at least clearly superior to the four newer Swiss BCs. And you have to develop the guns too.
Well, I do think she is seriously undergunned for her size. Even with 305/L50 guns she is at a disadvantage against pretty much all major artillery ships.
I did a re-sim I played around with, and you could get eight of your 35/45 with fairly minor modifications. I lowered freeboard with 1 to1,5m, reduced upper belt to 105mm, end belts to 75mm and torpedo bulkhead to 40mm. While it is not fun to reduce armour, I do think it is worth it to get 20-25% greater power from the main battery.
However I do not agree on the "surrounded by destroyers" fear, she is fast enough that all but the very fastest (35-36kts) DDs will lack the margin of speed needed to surround her unless she cooperates.
My DD comment is rather on the weak secondaries in case of the ship finds herself in a tactically disadvantageous situation.
the name of the ship will be derrflinger, right? ;)
Agree with Korpen - and if you take her in that direction - Mackensen? :)
With a bit more thought:
First - must say really like the Current S & G - possibly my favourite ships in nverse!
I particularly liked mix of good speed for their day, well protected and good armament vs BBs (6 x12) and CLs (6.7s) - a neat package
However - following on the above comments this draft design rather puzzles me:
BB protn (35% armour) - so can/will go in the Battleline? - but weak Main Battery for the size (even if the 305s are 50Cal) and Secrs - only 12 guns vs TBDs - your BB has 24
Thick Upper Belt - useful to give more complete protn vs Cruisers - but Secr'y armament also weak on calibre - 5.5 better vs. CLs than 4.7s
35 Mines ?!?
What will she be used for??
This BC is good for front line action with a very high protection.
Armament is made to engage 1st generation of BC, not 1918 BB or BC...& she is 31200t.
;)
Curiouser .. and curiouser ???
A New Fast Heavy ship with lovely new (liberating) engine tech. (that will cost $$$ and take 3 yrs to build?) with a hoped /planned for lifetime of 20+ years
- equipped with (for its size) quite weak main + sec'ry armament - and only designed to counter existing opponents .....
Made a few changes to Ersatz M. Thinned the belt to 35cm, as 38cm is overkill and wastes weight. Brought speed inline w/ the current battleline speed of 23kts. Saved weight allowed for slight lengthening for better seakeeping, and allowed a modest beam increase to get better stability/steadiness.
