KKK light cruiser 1915 - worth it?

[Borys]

Guns are in the Japanese arrangement - back to back on bow, two wing guns, then small pyramid aft.
To make use of the new gun I developed.
Else is pretty much identical to the Marie Theresie ...

Why the change in main gun caliber?

[Jefgte]

For hands manipulation...?

then...why hoists...??


Jef ???

[Borys]

The seventyfivepunder is for Fleet Cruisers and for Battleship secondaries - for shooting at unarmoured "torpedo delivery systems". Yet lethal enough not to be ignored by enemy fleet cruisers.
The 100 pounders will be retained on Trade Cruisers.

And yes, for hand operation.
The hoists are already there :)

Gotcha.  Well, she looks fine in all other respects.

The OTL gun can be either the French 138mm from 1910, or the Russian 130mm (5,1"?) from 1913, as the main inspiration, the Italian 135mm, dates from the mid '30s.
