You are right about the battlecruiser' armor, but this specific ship is much lighter than the Lexingtons were. To fix this I dropped the range by a thousand nm and increased the belt to 6.5in main, leaving it still short of armor but not as critically.Steve wrote:Your destroyer's range is horribly, horribly terrible- it would need to refuel constantly on the way from your east coast to west. And that first battlecruiser is waaay underarmored. Even the notoriously-unarmored Lexington design was to have 7" belt. British BCs typically had 9" and Germans even more.
Sticking with coal makes sense if your oil access is minor, but it does cost you in range per ton of fuel (also, coal grades can ruin performance; lower grade coal doesn't burn as well and you lose power; witness one reason for the fate of Cristobal Colon at Santiago de Cuba).
The short range destroyer will remain as a Red sea only vessel and I created an heavier ship to supplement it.
As for oil versus coal I think I am going to have to change the Shakir class to coal. Hmm, maybe only the two that are under construction now.
