Is this class in home waters or the NEI?
Quoted
There are many things I´d like to comment on. Please don´t take it as personal offense. Points in no order
Quoted
1.) With a hull 8,85m deep I can hardly believe those ships can use mamy if any dutch harbors (homewaters) in 1915.
Quoted
2.) Accourding to your drawing engine rooms are seperating your aft turrets. Her stats seem to differ.
Quoted
3.) Her armor sheme is unrealistic and ... ahem ... weird.
Quoted
3.a) The amount of armor used (36% of her weight) is maybe too much. Only full-scale BBs of her era can (hardly) beat that much armor. The british QEs had approx. 31,2% of their weight distributed to armor for example while the last two classes of german BBs had ~40%.
Quoted
Also: The total percentage would be different for your design if you hadn´t "cheated" on her size (see below). This has to be considered.
Quoted
3.b) The germans prefered armor over firepower and you seem to have something similar in mind. However, 380mm plates for belt and turrets are too much. Even the Germans - who build the best BCs ever during those years - never used belts of more than 300mm for their Large Cruisers. Of course there is no reason not to use thicker plates in an alternate world but it is my personal opinion that everything beyond 320mm is pushing things a little bit in 1915. Same for her turrets.
Quoted
I think the amount of armor used and the firepower installed is heavily off balance.
Quoted
3.c) The distribution of armor doesn´t make any sense to me. Your vessels belt armor is thicker than anything ever seen in the real world except mighty YAMATO and the british KGV while her turret armor is only beaten by some late US-standards and WW2-BBs (!!!). On the other hand her CT armor is heavy enough to make incoming heavy shells go boom (set their fuze) but not to keep them ouside. 1mm light gun shields don´t make any sense, too.
Quoted
Quite some BB designs I've seen around here have those 380mm of armor on belts, turrets, ot both...just not that early.
Quoted
4.) You´ve given her a range of 20000+nm at 10kn !!!!
Quoted
4.a) Of all BB/BCs I know only british VANGUARD with 9000nm at 20kn and YAMATO with 7200nm at 27kn (figures as planned!) are getting close! Even the german diesel driven PBs couldn´t beat that kind of range. Up until the first nuclear driven warship I can think of nothing to beat 20knm at 10kn (not taking ships of sail into consideration).
So I ask you: Honestly, don´t you think you´re pushing things a little bit?
Quoted
4.b) With such a great range you´ve also heavily modified the vessels displacement. This is what I meant with "cheating" above. If you hadn´t done so that vessels size surely would have been different - and most likely larger than any other BC laid down in the real world up until HMS HOOD. You know, she´s already as large as the british R-class BC as build....
Quoted
Hopefully I´m not sounding rude but you´ve to work on that design again. That´s my personal opinion of course...
Quoted
Maybe. not sure either (again I've seen this done in other players' ships, I recall one japanese ship having an insane range too).
Quoted
These battlecruisers kept India's design team up late many nights, trying to figure out how to defeat the heavy armor and speed.
Considering what they came up with, I don't dare question your design...

Thanks in advance

On armor I already gave some examples.

So here are some historical examples regarding range

Range at 15 knots for the Zeven Provincien is 8563nm at 15 knots, 4281nm at 20 knots...

ZPs were designed and built for service in the Far East, that shouldn't be a problem

So your relatively small navy can affort to build a large portion of its capital ship fleet that will never be able to sail in homewaters? I don´t buy that...
Where were those units build? Also in the NEI?
Quoted
Just curious... Of course I could be totally off regarding depth of waters in Den Helder etc.
