No amount of high-tech special systems could save Berlin from a two-front war.
Key point: The Allies simply outproduced Germany and had more resources to use to win. In fact, some of Hitler's vanity wonder projects may have come at the cost of trying to win or come to a truce.
During Germany’s early string of victories between 1939 and 1941, Hitler informed the members of the nation’s aerospace industry that he had decided to impose new restrictions on aircraft research and development. However, by 1942 the Führer and his Air Force High Command (Oberkommando der Luftwaffe) had recognized their mistake. With the increasing weakness in the fighter arm, Hitler saw that his old faithful aircraft like the Messerschmitt Me-109 were losing ground to the new Allied long-range fighters, such as the North American P-51 Mustang, used to escort U.S. and British bombers that were devastating Germany with little resistance.
