I wouldn't say that modern stealth tech is based on Nazi tech. The Horten brothers developed for the Nazis the first flying wing design andf that design hasn't changed much since then. Since it could fly lower and create less drag, it was about 80% less visible by radar than conventional bombers of WW II. Of course, it was all made of wood and not the carbon fiber composite materials used in modern stealth bombers. Those two brothers were brilliant. I find it interesting that nobody scooped them up after the war like they did with many other Nazi scientists. My understanding is that they were hobbyists and not trained aeronautical engineers. Their designs were unconventional, so they probably were seen as more odd than revolutionary in their designs. It is possible that they might have been unwilling to work for a third party. That design certainly is amazing.
