There were loads of advanced weapons projects in Nazi Germany, but most never saw the light of day. For example, they had 35 projects to build proximity fuzes for shells and missiles, but didn't field a single proximity fuze during the war. America, on the other hand, had one such project and made millions of proximity fuzes.
