Both the US and the UK gave up pretty quickly on the Walther Hydrogen Peroxide powered sub because of the continued explosions of the fuel. That was also a problem with the ME-163 Komet, as unused H2O2 had this nasty habit of exploding on landing, which was not very good for the continued good health of the pilot.
well thats typical for new technology. The allies were further behind
As for the myth that the ME-262 could have been in combat earlier, that is just what it is, a myth. The problem was engine unreliability, and the fact that not until the Germans had a look at the landing gear of a P-47 did they come up with the final gear for the ME-262. The test pilots hated the engine of the ME-262 as they never knew when it was going to fail, only that it would.
Hitler didn’t use them as proper interceptors when clearly Germany was not in need of more fighter-bombers. If Hitler had decided to begin with their natural talents it would have been used earlier to greater effect. Also, if Germany was winning the war by 1944 these units would have had fuel and sufficient quantities produced to outclass all allied counterparts. IN groups these were devastating to allied Bombers and more than a match for escorts. Plus other planes coming on line even better
As for rockets, that depends. Liquid-fuel large rockets, yes.
Although if Goddard had had the funding that Von Braun received, that might have been more than a bit different.
Air to ground rockets for ground support, no. Nothing even close to the US 5" HVAR, or the 11.75" Tiny Tim. Air to air rockets, yes, because they had all of those B-17 to shoot at. Oddly enough, the Allies did not have that many German bombers to shoot at after 1941. Ground to air rockets would be a toss up between the UK and Germany. Ground to ground, about even, although the Germans never had anything close to the rocket barrages launched by the Russians, or the US during an amphibious assault.
well thats the same thing as the A-bomb program as well. Hitler didn’t support it and it was done only as low level. If Hitler invested in the Bomb early and made it priority he may have got it in a few years.
Germany was way behind in aircraft engine development, mainly because of poor fuel and not having a good turbocharger for non-Diesel engines. As for the jet engine, which was developed by an Englishman named Whittle, if the UK had been able to devote a bit more time to research, rather than fighting a war, I suspect that they would have had a jet fighter a year or so earlier. The Meteor was used to shoot down V-1s. The Germans were a long way from anything comparable to the B-29, and the US had the B-36 under development. They never did have any carrier aircraft, although the British is some respects were in the same boat there. Transport planes were pretty much a US monopoly, with the German ones being hampered by having too many military characteristics build into them.
The Germans had no need to long range strategic bomber. Its not because they didn’t have one means they didn’t have the means to build one. If the Reich was finishing off Russia, they may have developed some to bomb the ural factories and if they got far enough to bomb America. Only USA needed long range bombers because the way the war turned out.
ON V-1 basically any plane can shoot those down. The V-2 was impossible however, But the Germans also had many other planes in development and only didnt need these capabilities, but had the inventiveness to outclass allied technology even when they were losing the war and lacked resources. If they were winning the war it would have been more pronounced.
