thoughts? the 393 foot limit realy limits them
I think one of your big cruisers would be more effective - it could better chase raiders, or have the speed to avoid a lopsided attack.

I tend to agree these started to be evolutions of the 10" cruiser. im afraid that im becoming a one trick horse i did such a good job on the 6X10" cruiser that everything i come up with pales in comparison T.T
My thoughts? Go for a longer ship. :)
I would also try to get rid of that 3 meter gap in your belt (between main and ends belt).
the 393 foot limit is based on a type 2 Dry dock, i may never build one i actualy like. For me its a chalange, trying to build somthing that is basicly imposible. In the end ill end up going proly 450 feat or so to make it a decent ship but its a fun exercise.
Type 2 is 170 meters/557 feet... 393 feet is the limits of a type 1 dock/slip.
You'd rather build first-class battleships and relegate old ones to the colonies. And your stability is very low for a 14" gunned 20kts ship. Of you want to keep displacement low, use 12" guns.
ya im still playing with it
The one quick addition of stability is adjusting the trim. If I can't get to a steadiness of 70% without having stability drop below 1.05, I usually set the trim so steadiness is 50%. Your trim is set on 54.
Totaly unrealistic... I just drew it in virtual ship yard NO WAY it would work. the ship is just 2 masive Turrets lol
What do you expect. Something that just hit me, This thing is about the same size as a Deutschland. It is slightly wider than a Deutschland, but a massive 60 meters shorter. Deutschland carried triple 283mm guns and this one carries triple 14 inch guns... so even if it does fit, it will look incredibly odd and it will end up in the "An incredible bunch of fuglies" thread. :D
LOL i know i expected it would look funny just didnt realise how funny it would look ya know
