I am trying to build a world where USN, RN, IJN, and KM are companies that build WWII ships that compete for ship components sales with more diverse/versatile roles in armour, turret, shells, rather than just solely hull class DD, CA, BB. The world can incorporate things are still on the drawing board like the IJN submarine carrier. Is there a data source that lists all the specialities of warships in that era?
My limited knowledge could only think of torpedo specialised DD like Shimakaze or hybrid CV like the Oyodo. Or a submarine hunter like Fletcher. Are there more diverse classes I can use?
Perhaps something like Belfast's radar speciality. I'm not sure whether it is historically accurate that the Belfast had better radar when compared to BB.
