Hitler's Stealth Fighter
DesScorp writes "Aviation Week reports on a television special from the National Geographic Channel on what may have been the world's first true stealth fighter, the Horten Ho 229, a wooden design that was to include a layer of carbon material sandwiched in the leading edge to defeat radar. Northrop Grumman, experts at stealth technology from their Tacit Blue and B-2 programs, have built a full-size replica of the airframe and tested it at their desert facilities where they determined that the design was indeed stealthy, and would have been practically invisible to Britain's Chain Home radar system of WWII."
What DIDN'T Hitler Do?

I believe that the advances in detection technology would always have allowed the allies to hear a Horton Ho.
what with swastika flags and all. I'll be in trouble if someone has overseen my screen just then, being a german living in Britain.
every other stealth programme goes with the notion that it has to be invisible at all times.
Not exactly. You will never be invisible, and stealth technology/employment is a lot more complicated than "we'll just be invisible". Even today, remaining undetected until past the threat is a fairly well-used technique. Just look at the F-22. And even if your airframe isn't fully-LO, you see a lot of emphasis on reducing frontal RCS. The B-1, Typhoon, Rafale, and Super Hornet all use some degree of RCS reduction, which buys them that much more time to get in close. Modern cruise missiles use the same principle.
Interestingly enough, raw speed can buy you some of the same advantages. Go fast enough and high enough, and the defenses just won't have enough time to react, even if you're lit up like a billboard.
The meek may inherit the earth, but the strong shall take the stars.
If you aren't mature enough to look at a swastika in a relevant place (we're talking about Nazi Germany here) you shouldn't be on the internet. Let me guess, you are also for the elimination of the flag of the Confederate States too? Please, show some maturity, if you can't handle seeing a swastika, perhaps you shouldn't be looking up information on Nazi Germany.
Taxation is legalized theft, no more, no less.
This article is utterly bogus. Not that National Geographic has ever been known for quality writing on highly technical topics.
The Ho 229 was built as it was specifically to meet the "1000-1000-1000" bomber contract. This called for an aircraft that could fly 1000 km at 1000 km/h while carrying a 1000 kg warload. And it had to be built of wood, because all of the aluminum, and metalworkers, were accounted for in current projects.
The only way to possibly meet the speed requirement was through jet engines. However, jet engines of the era were extremely inefficient, especially German ones where poor alloys limited exhaust temperatures in the turbine. So in order to get the range while keeping the speed, you needed to cut drag to an absolute minimum.
And that's why the 229 looks like it does. It lacks the profusion of surfaces that conventional designs had, and minimized wetted surface due to the almost non-existent fuselage. This thing is all wing, which means you're losing all the parasitic drag.
ANYTHING else, including these "stealth" features, were utterly secondary.
Moreover I have a very serious problem with the claims that this plane is stealthy. Compressor disks in the engines are an extremely effective radar mirror. This is why the F-117 has "blinds" over the inlets, or why the F-22 has a S-shaped intake system. As you can see in the pictures, in the 229 the compressor face is directly exposed to the front.
Sure, the CH radars were longwave and wouldn't have been good against this aircraft, but that would be true of any small jet of the era. They were extremely good against targets a few meters in size, like a propeller, but anything smaller would be difficult to see.
Claiming this plane was developed _as a stealth plane_ is like claiming the DC-3 was a swept-wing design. Accidental features do not indicate design intent.

Technical sophistication is one advantage on the battlefield, but manufacturing capacity is also important.
The Germans choose technical complexity over quantity believing that superior machines could beat the vast numbers of inferior machines the allies built.
The Germans were wrong.
As Stalin said "quantity has a quality all its own". A stealth aircraft or two may have been pretty trick, but if you have thousands of targets to bomb, you better have hundreds if not thousands of aircraft (and pilots) to do the job.

Hitlers single, fatal mistake was taking on the Soviet Union without first ensuring that Britain and the rest of the Allies were out of the war for good. Had Hitler not committed to the Eastern Front, he could have easily have prevented an Allied invasion, and indeed have triumphed in North Africa.
Hitlers basic failure was greed. He wanted the Soviet Union as well, when there was no possibility he would have won that war due to the sheer size of the USSR. He had no heavy strategic bombers, nothing to interfere with Soviet production facilities once they were moved further east, and that doomed him to lose.
There was a short story written by Arthur C. Clarke titled "Superiority" that discussed this. Of course, it being science fiction, the weapons were very interesting (matter annihilators, space distortion systems). Also, since it was written (in the 50s?) some of the vocabulary is quaint (I think the term "torpedoes" refer to what we would call missiles).
Still I didn't know (according to Wikipedia) that it was (once?) required reading at West Point! (For those not from the U.S., that is one of the premiere military academies).

I'm sure in 20 years we'll find German plans to make ray guns, giant mech fighers, etc. Castle Wolfenstein game plots seems less & less like fiction as the years go on. :)
I don't think Hitlers underestimation, if he even did, of Britain and Frances wish to fight for Poland was damaging at all - by the middle of 1940, Germany had caused France to capitulate and thrown the British army out of Europe. Had Germany won the Battle of Britain that year and not invaded the USSR, then in all probability Europe would still be in the hands of the Third Reich.
Without Britain as a staging post, the US, Canada and Australia would have had no firm base to launch an invasion of Europe. With Britain out of the war, Hitler would have held North Africa as well, preventing the Allies from using that as an invasion staging post. Basically, the Allies would have lost any easy gateway into Europe, and with that went any hope of liberation.
He wanted the Soviet Union as well, when there was no possibility he would have won that war due to the sheer size of the USSR.
So, don't get involved in a land war in Asia. Got it.
Dewey, what part of this looks like authorities should be involved?
I can not find it now, but I remember encountering an article several years ago in a local Las Vegas newspaper that described how the stealth fighters could be detected easily. In places like Nevada where there are secret military bases all over the place, there are hobby stealth watchers and they had discovered that there are so many cell phones in use all over the world that stealth fighters get lit up like a x-mas tree from the ground based signals emanating from the cell phones. Even amateur stealth watchers could track them flying around the Western United States. It was not long after that article the military officially started dropping all plans for future production related to designs based primarily on right angles and radar.
Can anyone find the article or info on this?
