Even with no materials shortages at all, they could not have done much better in terms of jet engine quality and reliability.
I dont believe that... If Goering was able to neutralize the bombing threat to Germanys industrial heart, many things would have advanced further along than what they did, including jet engines and other technologies...

U know what happened when they bombed a manufacturing facility flat??? They killed off all the engineers and designers and high level production people.. They are'nt easy to replace.... It definatly took its toll on the future productivity of Germany...

HATS OFF to the brilliant Allied planners!!!!!!!

But that's not the nature of the German problems in mass producing jet engines. This was not something that was going to be solved in the short term, it required a widening of their industrial base, and that takes more than just a few years, it takes a decade. Germany lacked O2 injection smelters and the other basic alloying technologies needed to make the better metals you are refering to. The USA was just barely comming online with this technology at the time, and it had a 10 year lead in such techniques.

Likewise, the whole nature of the German machine tool industry simply didn't support the mass production of things like jet engine turbines. They would have needed to completely change how they did things, and completely rework their machine tooling, something that would have taken a minimum of 10 years, probably more, even if they weren't in a war. Being that they were in a war, they simply could not do it, it would have meant shutting down too much of their war industry for far too long.

As for the future productivity of Germany, after the war under the Marshall plan, the USA built O2 injection smelters for both Germany and Japan. Then, in the 60's and 70's (and beyond) the US Steel industry was reeling because about 70% of the US steel industry still used the old Bessemer process, which generates inferior steel, and they could not compete with German and Japanese steel quality.

Relatively few engineers, scientists, and "high level production people" were killed by Allied bombing. Those kinds of people do not generally need to be in the plants where the products are actually made. Even the workers in the plants suffered relatively light losses (ever heard of a bomb shelter?).

The main problem was that, in the time the Me 262 was built, Germany had a lack of materials and the Me 262 wasn't a priority. And Hitler was dissapointed of jet fighters, so he ordered that the German industry had to build bombers despite of the lack of resources.
And for that time the Luftwaffe (mainly for Goerings fault) had lost all chance to keep clear from allied aircraft Germany's skies. So we just can wonder what would had happened if they had the time and resources to solve all the problems that the marvelous plane faced.

The whole argument that Hitler's demand for bombers significantly hurt the 262 program has been prooven to be a myth. This accounts for at most, about 100 fewer fighter versions of the 262 seeing action in WWII. It is well established that in WWII something around 300 262's saw action, perhaps 400 might have seen action if the directive for the bomber version had not been issued, but even this is in doubt because those diverted 262's are probably counted in that 300 figure. The problem was a lack of engines - at least 1500 262 airframes were completed, and there is good evidence the number was more on the order of 2500, but engines were the bottleneck - 400 pairs of engines was the best they could do (plus test engines and many many engines that failed to pass inspection, and of course a relatively small number of engines that went into other jet types).

Study it in detail and you will find that the materials problem went deeper than that. Germany just didn't have the kind of hi-temp titanium alloy steel needed for jet engines. This is why the 262 has the engines in the wings, putting the engines on the centerline would have overheated the tail section too much. You really have to get pretty deep into the history of metallurgy to see that the truth is that in WWII, only the USA had the kind of metallurgy technology necessary to make such alloys, and even in the USA, these resources were quite limited. In 1944 the USA was shipping steel and other alloys to the Soviets that surpassed those available in Germany. Germany had some very excellent steel armor out of the Krupps company, but that was the limit of their metallurgy tech in WWII. And even this was more a matter of understanding what to make than the technical ability to make it. USA class A armor was actually more pure and harder than Krupps armor, but as it turned out this was not really desirable in such armor, and the class B armor which was softer was found to be superior for most Naval applications.

As I've said before, this kind of technology derives from the techno/industrial base of a nation, not from the top of the technology pyramid. German end products (the top of the pyramid) were very good, but in general their base technology was well behind. They simply could not broaden that base to be anything close to what was available to the USA given that they had only about 10 years to ramp it up for WWII and Germany was only about half the size of America. US base industrial technology was at a high point because of the huge US buildup of both rail and shipping from the Civil war through WWII.

It was one of the problems.... There wasnt one big problem like ur stating... It was multiple problems that added up to the shortage of engines......

Specific smelters were ONE of the reasons for it.... Not the only....

Also the fact that we didnt have anyone bombing our technology back to the stone age either.....

So far all I have seen out of u RG is the ability to point out specific problems for broad issues... And in the process, say that other people are wrong.. U do not have all the answers, as do none of us....

Thats a lie.... I have read and seen alot of documentation and it was a fact.... Germany lost some of its best people during bombing raids......

Ever hear of a big bomb that destroys bomb shelters??? The Allies used them u know.... I dont know where u got that info, but to say that regular workers suffered lightly is a joke... They were expendable items that Nazi Germany could have cared less about.... Thousands died....

Yes, one of many problems which made the jet engines impossible to mass produce. I never said this was the main reason. The biggest reason was the shaper based machine tooling common to Europe at this time. Without more modern milling type machines, mass production of jet engines was nearly impossible.

Again, I didn't say it was the only reason. But lack of the ability to refine pure steel with a controlled carbon content was a huge problem in creating the metals alluded to. Without this technology, the smelting process introduces impurties into the resulting steel which create weak spots in product derived from it.

No, that is exactly my point. The bombing really didn't have that much to do with it. We are talking about a tiny amount of material needed for the rear fan of the tubojet engines in question. No amount of Allied bombing was responsible for this materials shortage. It was simply beyond their technology to produce the quality of alloys needed in anything but labratory quantities.

No I've pointed out two huge specific problems faced by the Germans in building thier jet engines in WWII; lack of the necessary metalurgy technology and lack of the kind of machine tool industry needed. There may indeed have been others.

Sure, they lost some of their scientists and engineers in the bombing. Mostly in the last few months of the war. But by far more survived. Messershmit, Tank, Heisenburg, Von Braun, all survived. You make it sound like some huge % of German scientists and engineers were killed in the bombing early in the war, when the fact is that a small % were killed, mostly very late in the war by the huge British firebombing raids of late 1944 and 1945.

If you look at the figures, the numbers of war industry workers that died was lower than that of the average residents in the cities that were bombed. You are totally wrong in your assertion that the average German was considered totally expendable to the Nazi's. They were willing to sacrifice citizens but they took serious action to protect them. Had they had the disregard you imply, there would have been far fewer 88's defending German cities and far more on the E. Front. War factory workers in particular were valued and bomb shelters were readily available in most cases.

Sure sometimes a bomb shelter might have been destroyed, but it was uncommon. Again you make it sound like this was commonplace. And furthermore, when it came to scientists and engineers, which was the original group being discussed, shelters were very good. Those that did die probably died because they were at home during an attack and could not reach a shelter.

The biggest loss of German scientific and engineering talent was self inflicted - they were Jews. Aside from this, losses of such talent were very small throughout the war, as these people were prized and well protected, and tended to work in places very well protected from or not likely to be the subject of allied bombing.

In each instance you want to treat the rare case as if it were the usual case. That is not how it was.

I will agree that some of the biggest losses to German engineering were with the Jews however being bombed all the time did not help the problem. The Germans were not behind the allies in most areas of technology, infact they were ahead in many of there designs. I think given a few years they could have worked out all the kinks and there would not have been these problems. Like everything there are problems in the beginning, the Germans lacked time. They had to push the products out to fight the oncoming allies. Given time I am sure they would have made superior versions to the jet aircraft they already had and even more better aircraft than they already had.
 
One problem was the fact that the failure of Germany to reserve a source of Chromium, necessary in blade alloy to prevent the fan blades stretching. This gave German jet engines a short life.

I am not disagreeing with that. I'm trying to point out that while German designs were quite innovative, their industrial base was simply not competitive with that of the USA. Design of end products is at the top of the industrial pyramid, and at this level the Germans excelled over their 10 years of development. But materials sciences (amoung others) are derived from the base of the pyramid and there was no way the Germans could compete with the USA in this respect.

Putting this in simple terms, the if the German industrial base was 100 units wide, the US industrial base was at least 300 units wide. Therefore, the highest the German's could get was (again in simple arbitrary terms), lets say, 50 units high at the top, but the USA could potentially reach up to 150 units before having to widen the base.

The German scientists and Engineers did the best they could with what they had to work with, and created some very advanced weapons. But in the end, the USA (with a lot of British input) far outpaced the Germans. The Germans started their war effort and especially their war R&D in 1935, and over 10 years the most advanced weapons they were able to create were more than matched by the USA's 3.5 year effort. This was not because the German scientists and engineers were stupid, it was because it was simply harder for them to progress beyond a certain level given the respective industrial bases.

And that all comes down to time though. The US scientists had time to conduct tests and properly put out the best product they could, the German scientists were always on a short string having to develop at the shortest posible time. This was because Hitler wanted output, he wanted to see finished products in a matter of no time, which was a major downfall. Also the fact that the Germans were fighting a losing battle did not help the fact. I will agree with you on most of what you posted there.

I disagree. The Germans started war level R&D in about 1935, they had 10 years to develop war technology. The USA did not get serious about such R&D until 1942, giving them just 3.5 years of development time.

Take the Jet programs for instance. The German jet program began in 1937 and generated their first flying jet, the He178, first flew on August 27, 1939. The Junkers company had been working on jet turbines as early as 1936 and had a prototype in 1938. Messerschmitt started work on project 1065 in 1938 and submitted the Me262 proposal to the RLM in May 1940. And on July 18, 1942 the first prototype (the -V3) flew. It was not until June 1944 that the plane actually entered combat, with the first operational units going into action in October. I will agree had politics not interfered it might have entered combat a few months earlier. But the point is from first flying prototype to first combat ready production units was at least 4.5 years, with 2+ years of prior R&D on the engines.

Now compare this to the USA's effort. Let's cancel out the 2 years of pre first flight engine development by the Germans with the British contribution of the initial jet engine tech supplied from the Meteor project to the USA and just compare from first flight. The YP-59 first flew on Oct 1st/2nd of 1942, the first YP-80 flew on January 8, 1944, and the first 45 production units of the P-80 were deployed in very early 1945. Less than 2.5 years from first flight to delivery. The P-80 was withheld from combat for strategic reasons, but had the war gone differently, lets say holding off the Soviets and defeating the D-Day invasion, there would have been more P-80's flying by end of summer '45 than 262's. Had the 262's been rolling off the production line in early 1943 (including working reliable engines) the German's would have dominated the air-war by the middle of that year. By the time the Allied jets arrived, Germany would have had something on the level of the Mig-15.

The argument that Allied bombing was a big part of the hold up on the 262 development does not really hold up because Allied bombing did not significantly interfere with German industry until 1944, and even that contention is disputable (there is good evidence that Allied bombing had little effect in 1944). The real issue was simply the scale of the two industries and to a lesser but significant degree the way they were managed.

I agree time was an issue. But for any technical project, the USA was likely to complete the project 2-3 times faster than the Germans depending on the level of focus. It was just a matter of industrial scale, US industry was many times larger than Germany and had more qualified engineers to work on projects and they genrally had more advanced facilities and better materials to work with. Germany's lack of focus also helped the Allies. Remember Germany didn't "get serious" and go into a "total war economy" until 1944, after it was all but over.

Germany was also hurt by its decisions as to what kinds of projects to undertake. The V1 and V2 projects were uselss, neither was going to win the War for Germany w/o nuclear weapons, and they had no reason to expect such weapons would be available until 1947 or beyond. The super tanks and Me262 were likewise not going to win the war. Neither of these weapons had the ability to take the war to the enemy, both were defensive. In general, the wonder weapons were more about making lots of reichmarks for the right Germans - such projects were high profit projects assuming the riechmark was going to have long term value.

The Germans failed to produce the weapon they really needed, the VT fuse. Had they been able to produce a working proximity fuse (they tried hard but failed) Allied bombing would have been defeated and the Luftwaffe' would have been freed to pursue more offensive operations. German artillary would have been twice as effective and they could probably have held off the Soviets. To me, the VT fuse and of course the A-Bomb were the two "super weapons" the Germans needed but did not succeed in creating.

So I think the argument that the Allied scientists had more time to work with than did the German scientists is incorrect, the German scientists and engineers had more time.

I will agree with you that the V-1 and V-2 took up needless time and effort and Hitler was stuck on having his vengence weapons. So I will agree with you that Germanys desisions did hurt the Jet projects. I will also agree with you that US industy was larger. And if you look at the fact that the Germans were working on jet engines in 1936 then yes I would agree that time was not a factor, however what I meant by German scientists not having time is that basically politics put a time limit on how long it took for them to put out a working product. They did not have the sufficient time to put out better products. In the latter parts of the war Germany was putting out inovative designs that just were not quite ready yet and that was because Hitler wanted them in the air immediatly. Now if they had had sufficient time would these products have helped their war effort? Probably not. I do however think that given sufficient time they could have turned out aircraft of great value as you said like a Mig-15 type of aircraft. For example just look at the Ho-229.
 
Something the should also be taken into account was the slave labor that was used in Germany was also "helpful" when they worked on, assembled, transported these aircraft. To much of that kind of help could ruin your whole day!
