Question on monitor...

Isn´t 6" a little bit too much for a torpedobulkhead?

well

Its an internal side armor slope that doubles as a torpedo bulkhead, it sits behind the ships buldge.

note!

I have removed the rebuild of the Siboney and the decomisioning of the Evanor due to the fact that I kind of went ahead of myself and removed them from the fleet prematurely leaving me without carriers! Once the Arrogant and fearless are completed the Siboney and Evanor will be decomisioned and converted. All my subsiquent quarterly reports will be free of major errors.
Finnally the fleet of Atlantis seems to be up to date minus small combatants and i will post a fleet summary soon in two parts.
