It's a good general purpose ship. I'd worry that it's too slow to escape other cruisers, too lightly armored to withstand 155mm+ shell fire, and too lightly armed to seriously duel most of the cruisers running around.

Good for colonial station use though.

Byzantium has 27kts cruisers and AGBs in these colonies.
-24 cruisers from 4750t to 6750t with 191mm guns.
-6 cruisers from 7450t to 13000t with 234 & 254mm guns.
-14 x 3000t Armored Gun Boat with 152 & 191mm guns.
Class C16 would be assigned to colonies as well.
27kts speed and improved shielding would be better suited to working with these "buddies".

Of the three, I think the panzerschiff is the best-balanced. The 9- and 12-gun ships seem under-armored and too slow to work cruiser roles.

This is also my preference. I love the Panzerschiff style.

The Panzerschiffe is going to have the right amount of armor to fight in its class against the other ships with 9-11in guns running around. The 12in gun has the punch. That being said, if you're trying to kill cruisers, for the weight the 12 gun design is probably best. Or make the 9 gun design just a little heavier and buff its armor to over 6in.

I look at your designs and see how inefficient mine are.....for the record.
