Yes and no. One of the curious features of the German wartime economy was that it fostered a great deal of investment into research and development. Private firms would use their wartime profits to cycle back into the company through R &D. The Third Reich's polycentric nature meant that it was easier to find a powerful patron justifying these efforts and funnel more money into research. So in fields like aviation, the Germans had a great deal of advanced concepts pioneered by 1945.

He's where the rub comes in, this intensive R&D was often highly wasteful and produced a lot of dead ends. The Me-262 was a paradigm shift for fighter aviation, the Bachem Natter was not. Natural resources bottlenecks like shortages of tungsten meant that it was far harder to bring advanced concepts to fruition. For example, the Ju 287 pioneered forward-swept wings, yet its nosewheels were salvaged from a crashed B-24. The Horton flying wings also used American tires. The use of ersatz materials made the application of research more fraught. Finally, the Third Reich added an ideological binder to research. Biology, for example, was tied to racialist precepts. To be active in German research, one had to have the proper racial and ideological credentials. This created a brain drain during the 1930s as many scientists who could not stomach the regime or vice-versa left Germany.
