So for the sake of argument (pick any reason you so desire) say that Nazi Germany has survived until late '45/early '46. Also operating under the assumption that the Luftwaffe doesn't have its head up its ass, the Me-262 has been in squadron service for quite some time now. This leads to the question of what comes next... Obviously the 262 has proven to be successful, so the Luftwaffe leadership would want another jet. Obviously the -183 and the Horten flying wings are aerodynamic deathtraps and not contenders for the role, and to be honest I don't know enough about the He-162 to pass judgment on that... I've always liked the look of the P.1101 but I also don't know if that was a viable design... Any other ideas?
