Well it looks like we received “night vision” technology from the Germans (not from Roswell, sorry Col. Corso) and by the end of WWII the Germans already had small, portable nuclear devices. Wonder what else we have 80 years on as a result of captured Nazi technology …
… “one of which was an infrared night driving aid, a first-generation device “by which an auto-driver can see the road on a converter screen from infrared reflections, thus enabling him to drive at high speed along pitch dark roads,” … from an Interrogation Report, Oberst G.

“It (a V-1 of some type / “V-1” was used often to mean any kind of rocket device) was to be piloted by German fliers in a suicide squadron, equipped with either a chemical or a biological weapon, or even a dirty nuclear bomb. The ubiquitous Otto Skorzeny was involved in this plan, using famed test pilot Hanna Reistch in what became code named Project Reichenberg.8 This fits with information that Hitler’s own adjutant reported Germany had a pumpkin-sized nuclear weapon prototype, a perfect size for a V-1 and a potential game-changer in the war". - “Adolf Hitler, Hitlers Tischgesprche Im Fuhrerhauptquartier, 1941–1944, 1st ed. (Athenum Verlag, 1951), p. 493
“Hitler’s adjutant Julius Schaub reported that a German uranium bomb the size of a small pumpkin had reached a prototype stage under von Ardenne’s supervision, ready for mass production at an underground SS factory in Harz, near Nordhausen. Curiously, when the source for this information, Hitler’s Table Talk, a German language book, was translated into English by British intelligence officer Hugh Trevor-Roper, all references to Germany’s nuclear research were deleted.”
