@HexHammer,
The German experiments with regard to atomic power and an atom bomb failed.
The Germans certainly did come up with "jet" engines before anyone else, but they weren't the only ones working on the problem. However, the idiot Hitler insisted that the planes be used as bombers, and the existing engine technology simply couldn't handle the weight. Therefore, although a flight-tested jet fighter was available in March, 1943, Hitler assured, through his stupidity, that it would not see service until very late in the war. To that extent, one could claim that Hitler was good for the world through his stupidity.
The rockets the Germans made were hardly advanced. Goddard in the United States couldn't make rockets so heavy, capable of carrying such a heavy pay-load, but he had far better control of his rockets. The V-1 was so slow, and flew at such a low altitude, that the British would send out Hawker Typhoons, which would fly alongside them, matching their speed, and then edge in and use their wingtips to tilt the rockets off course, causing them to slam into the ground and detonate. The V2 rockets moved much faster, and at a much higher altitude--but they were ludicrously inaccurate. Just because the Americans scooped up the rocket research crews at Peenemunde doesn't mean that nobody else had any expertise.
There are literally thousands of pages of careful analysis which show that absolutely no research of medical value was conducted in the death camps. Are you some kind of crypt0-nazi, a skinhead hiding in the closet?
The enigma machine? That's a laugh. The French bought one in the 1930s on the open market before it was classified by the Nazis, who were largely clueless until the Army tipped them wise. The Poles then engineered an "accident" on the road leading through the "Polish corridor" to Danzig, and got an up-to-date Enigma machine in 1938, which they turned over to the French, then leading the code-busting effort working on Enigma. However, it was the Poles themselves who, from 1932-39 basically devised the means to break Enigma codes. At Bletchley Park in England, even before the war began, English code breakers began working on Enigma encoding, and were very successful, even before they got a copy of the military Enigma machine. Reasonable estimates run that breaking the Enigma code shortened the European war by at least a year.
The first modern electronic computers were built in the United States as part of the Manhattan Project. The Germans weren't even in that game.
The Germans copied sloped armor from the Soviets.
German "advanced" military machines and hardware were material and cost intensive to produce, required high maintenance and were subject to frequent breakdown in continuous service. Not only were they expensive to produce, they had long production times, meaning that, for example, they produced a few thousands tanks during the war. The Soviets produced more than 70,000 tanks, and the Americans produced more than 50,000 of the Sherman tank model alone. The Germans fighting in France had a saying about that. "A Tiger tank can destroy ten Shermans before the Amis (Americans) can get them. The Amis always have at least eleven." Their aircraft was not only not superior, once again they were outproduced by the Americans and Soviets by orders of magnitude. When asked when he knew the war was lost, Hermann Goering said: "When i saw the first Mustang (an American fighter aircraft) over Berlin." Their artillery was not superior to either the Soviet or the American artillery, and the Germans greatly admired the American 155mm howitzer for their rugged reliability. The only advantage the Germans had in artillery was highly developed counterbattery techniques--something for which the Nazis were certainly not responsible. The standard German infantry rifle was a cruel joke. Their ships were not superior, either, leaving aside Hitler's stupidity in using his Navy.
USS North Carolina, which came off the ways in 1940, was superior to any battleship afloat, with a main battery of nine sixteen inch guns, and a top speed of 26 knots. This exceeded
Bismarck and
Tirpitz. Only German submarines proved to be superior to the Allied hardware, and with a loss rate of over 70%, that didn't do them a hell of a lot of good.
The Germans did not have advanced sonar, and in fact didn't have sonar at all. Their listening devices were equivalent to the ASDIC the English were using in the First World War. The U.S. Navy and the Imperial Japanese Navy had the most advanced sonar in the world, beginning far ahead of the Germans and advancing more rapidly throughout the war.
The German radar was a cruel joke on their pilots. The only excellent radar system they possessed was for their night fighters, and it was sufficiently unreliable that they would only allow their night fighters to operate individually, far away from the other night fighters, to avoid confusing the radar and to avoid mid-air collisions. The Americans developed the best radar in the war, and their surface radar doomed the Japanese Imperial Navy.
It was brilliant to use the 88mm guns in an anti-tank role. Once again, that had nothing to do with Hitler. Because the German army was highly adaptable--initially, before fear of Hitler killed all of the initiative--is not evidence that Hitler was good for the world in any way.
I really wonder where you get your ideas. That was a litany of the lies told by the Neo-Nazis.
