Could a serious Yugoslav navy emerge in this scenario?
Short answerIt is possible, but Italian resistance to a rival Adriatic fleet could turn the buildup into a crisis or war.
NotesYugoslavia could choose to build a more serious fleet. The difficulty lies in persuading Italy to tolerate another capable navy in the confined Adriatic as well as finding ships and money. Italian opposition could turn procurement into a diplomatic confrontation or even one of the smaller wars that shapes this timeline. The forecast therefore depends on regional politics rather than technical capacity alone.
