Battleships

So a layered system, such as SoDak (0.75"/19mm x3 + 41mm = 98mm) would have a value much higher than most of our systems, yet once someone goes over 60-70mm people start screaming "It's too thick". Weird.

Thats because people only seem to be modeling the main holding bulkhead here.

So if that's the only one we're expecting to see- and it's the one easiest to find listed in reference material-  then a SS2 "98mm" would seem to thick, after all Yamato's 76.2mm was "to thick". 

It's probably an area we should just all agree not to count the partition thicknesses, and just show the main holding bulkhead.  For one thing - there is dramatically diminishing returns in SS2 between simply having TDS and not, regardless of thickness- so it's not "seeing" the compartments, just the main holding bulkhead. 

The reason for that is simple; whether or not the ships have a torpedo defence system it will still have the bulkheads for fuel cells, double hull, and other compartments. So the steel for compartments in the TB is accounted for in "Hull, fittings & equipment" just like all other internal subdivision of the ship.
