I assume you mean XXI (as in type 21) U-Boat.. which were not available till the end of 1944 or early 1945.
If you last that long I suspect that it will not matter which flot you are in.. by that time you will be in one of the few survivng flots.. and type XXI will become an option.. a pricey option!
