Assuming I read all the missions correctly, this is what you're looking at if you wish to grind the Puerto Rico "for free". You'll notice that in order to finish all or even most of the directives, you'll need a wide variety of ships of all classes and nations. You'll also notice that we can celebrate the comeback of beloved and totally not questionable missions such as "sink x number of ships" or "get X number of plane kills". Oh and if you really plan to grind the ship without spending anything, you better have a comfortable chair as for example you're planning on scoring just over 800k base xp over this period, amongst other things. That's 400 games right there if you average 2k base XP.

And here are the extra missions in case you've got Gorizia:

Edit: I missed a few missions for stage 6, so if you're looking forward to grinding some 50k base XP in German or French DDs or score 2700 torpedo, rocket or bomb hits, that stage has you covered as well.
