In addition to what KaleunMarco has said, we have found that the game has a tendency to ignore any and all date restrictions that it sees fit to ignore, no matter what you try to do to avoid this. Included in this is ship "active" dates. We had ships (used to be "have ships") dated to enter early, leave early, and other entered late, and stayed the duration, or a combination of any set of dates. But, if the game wants to grab a "Type D" (late war ship) for convoy escort though, it will grab a Type D, whether it is September of 1939, or September of 1944. It just does it. Same with the Yamato or any of the myriad of merchant classes. My thoughts are that if the game did have the functionality to fully "Roster", it would run over the pedestrian anyway, then put it in reverse, and do it again... just because it can. lol - Needless to say, as time has passed, and the FotRSU mod has progressed, we have "controlled" (rather loose term in this game) ships by Type more than anything else. We have also dated ships' skins as we come across them, to be effective from 19380101 to 19451231, just in case the ships get called early or late... you can still somewhat restrict the skins by date, but definitely not a precise science.
