In this thread I have seen some references to the IC cost of a fleet. However, if my understanding of the economics of HOI4 is correct, producing ships will technically be "free", as long as they are at the bottom of the production queue and therefore only get ressources if those aren't tide up elsewhere. Therefore, any country with at least one shipyard should be able to supply itself with a small amount of convoys, destroyers and subs, as those do not require large amounts of ressources. Am I wrong in that assumption?
