Should RUb feature the Type XXI at all?

That's almost exactly how they are modelled in RUb. They are first available in July 1944, but delays in testing and sea trials mean that the first time the boat is ready for action is March 1945. You get enough time for one patrol. In reality, some faults and damage sustained in final deep diving tests prevented Schnee's U-2511 (the first XXI to be operational) from leaving on its first war patrol in late March. If those tests had not damaged the boat, it might have been ready by the date it's available in RUb.
