Very true the Type XXI was a game changer; so was the Messerschmidt Me-262. However, decisions were made (in addition to the Allied bombing of the Reich) that rendered these new weapons too few and too late to change the European War outcome. The Germans had a lot of other promising designs that would have caused the Allies much trouble, but these super weapons were too few and too late.
