You do not have to finish the last submarine quest that requires you to do Expedition 30 2 more times to unlock 31. I only did the first 2 sub quests which is only 2 Expedition 30s. I don't know if you need to finish last sub quest to recieve Z1 though, doing Exp 31 right now and will update here if I get her.
