The only remarkable things about her are her seakeeping and the heaps of unnecessary light guns.  Not to say that she's bad, just that in most respects, she's quite average.

Logi

Yesssss... The real Alaska went at 31.4kts. Alaska are good for their speed. That's something you don't have.

Not a remarkable amount of firepower per displacement. In otherwords, it's average.
The advantages are what Rock said.

PS: Yes... That's what I look for firepower per ton...

[Jedi mind trick] Must reduce armor for even more speed... [Jedi mind trick] :P ;D

Nobody likes the British BCs and prefers the German ones, but if you look at it closely, it wasn't the lack or armor that killed the British or the extra armor that saved the Germans. It was cordite that killed the British and it was the poor British shells that saved the Germans. Also the reason so many BCs where lost (compared to BBs) was that the BCs saw that much more combat.

I think Fisher got it right, firepower and speed come first, armor is for the weak. ;D


Getting back to the ship, she looks decent but undergunned. Suggest adding something bigger to give the Dutch heartburn.

I like that better.

thanks rock its either this or the Mackensen clone, so the choice is biger guns and more armor at less spd, or more spd lighter guns and armor.

Well, an compromise design, she is about in between the Dutch and the DKB in combat capabillity, but not convinced that is a good thing.

Al depends on what you want it for; I think she is a great ship for shooting up the Molktes, but you would want lager guns against Willheminas and Sharnhorsts.

think 6X14" would be enough? I can get them on it (just have to mess around with a few things) to go up to 8 though basicly I have to give up a knot.

Or his desserts are small,
Who dares not put it to the touch,
To win or lose it all!"

think 6X14" would be enough? I can get them on it (just have to mess around with a few things) to go up to 8 though basicly I have to give up a knot.
Depends, think it is enough to gain the upper hand vs. Scharnhorst (8 vs. 6 30cm guns is not enough for that IMO). No matter what you will be outgunned vs. the latest Dutch ships, so then 8 x 356mm guns would most likely be better. But not if they cost you the speed you need vs. the DKB ships, as they are the greater threat.
