On the 1st one I'd hate to be in that when some BCs 14-16" round smashes through that 9" barbette and GTs the ship.

[Logi]

It's a glass cannon, sure, I like glass cannons. But being a 35kt ship forced a lot of compromises. But that firepower is so tasty!

Tweaking JL20-A a tad yields JL20-C, which has shorter range and less misc weight in exchange for an extra inch of turret face, side, and barbette.

On the Cruiser -  I think 6 x twin 6" centreline turrets on 500' might be bit tight - what turret layout proposed?

On the BC - how about less firepower - 8 or 9 x 16" and more speed + bunkerage ?? - current range looks short for high speed operations ...

[Logi]

More speed is simply too expensive. The jump from 28-29 kts costs 0.05 composite strength. And it really isn't worth it IMO to gain one extra knot.

Main Belt is inclined 20 degrees, LOS Thickness is 12.77" or 324.5 cm, and Effective Height is 16.9 ft or 5.16 m.

If added with 1915 Krupp +10% Tech, Effective LOS Thickness becomes 14.05" or 357 cm.
