Hitler's Stealth Fighter 582

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."

      Hitler wasn't some demonic bad-ass bad-guy. He was a crazed political genius at the right place and right time. His downfall: he wasn't a real geek! He lost because of technical cluelessness! He didn't have the technical knowledge to realize the value of the wonder-weapons until late in the war when the 3rd Reich got desperate, and then it was too late. His right-hand man Goering didn't have a complete grasp of the importance of good intelligence and command and control. (He would have won the Battle of Britain, but he didn't know that he should've continued his campaign against the sector stations.) Even Hitler's understanding of economic warfare was that of an enthusiastic amateur.

      We won not because our geeks were better, though they were darn good. We won because we *listened* to them!

        As to the value of so-called 'wonder weapons', you should really read Arthur C. Clark's short story 'Superiority'. And before everyone says "it's just a sci-fi story, it has no bearing on real life" you should keep in mind that this story has been required reading at the US military colleges for almost 40 years.

        It's not just the time and effort that goes into R+D; it's building up a manufacturing base, getting the necessary raw materials, training your soldiers on new equipment, adapting strategies to the new technology (often a forgotten step), shipping the new technology out into the field. Then, you've got a new, fragile, and rushed technology being subjected to the worst conditions imaginable and having people's lives rely on it.

        The only obvious exception is the A-bomb, and even that was a fluke. The US was safe from invasion and damage, didn't have to worry nearly as much as Germany about having the whole project ruined in a bombing raid. You only need a few A-bombs to make a huge difference in the war, not true of most Germany's pet projects (except, obviously, their own A-bomb research). Since you only need a few, it's much easier to training, deployment, and maintenance are much simpler than a mass produced weapon.

        Not hardly, as Jacob McCandles would have said. The Germans biggest problem in the war wasn't their technology, it was their production. The USA built enough tanks that they could afford to give away more than the total German tank production. The Soviets built more tanks than the USA.

        Airplanes, the USA built enough to give away more than the Germans made. The Soviets didn't build more than the USA, but they built nearly as many.

        The USA built more ships than everyone else combined, much less the Germans.

        And on and on like that. Nothing the Germans could have done would have mattered a hill of beans, really - the only way they could have won that war was if they'd started building up their industry to USA/USSR levels in the 20's.

        And even then, their chances would have been slim at best - they didn't have the manpower to operate industry at our level and put 20 million men in the field at the same time.

      Still, I'm not the general public and given the sensitivity of segments of the general public to this symbol I think it's intriguing that someone would go through the trouble of a) creating the banners, b) getting on a ladder and hanging them in a hanger bay, and c) taking a "romanticised" photo of the whole thing. From the perspective of documenting a piece of technology it was unnecessary though it does add to the artistic aesthetic of the photo.

      Is it a brave decision? An insensitive one? Maybe the swastika simply doesn't hold the kind of meaning it did 60 years ago? I just find it somewhat peculiar.

    They'd only see the plane leaving, not arriving, which is quite an interesting compromise, as every other stealth programme goes with the notion that it has to be invisible at all times.

    This was designed so that, once it passed Britains coastal radar, they wouldn't be able to scramble fighters fast enough once they did detect them. Rather ingenious.

      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.

    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.

      You are going on about the shape, which wasn't even claimed to be for stealthiness. The claimed stealth feature was the layer of carbon material sandwiched into the leading edge of the plane to reduce its radar signature. Thus, it was the first plane to incorporate design features specifically for stealth. Nothing you said even addresses that. Whether stealth was considered of secondary importance, or whether all the components were designed for stealth, is irrelevant.

      • > Whether stealth was considered of secondary importance, or whether all the components were designed for stealth, is irrelevant.

  • It's remarkable that we had in our hands a German aircraft that contained within it a very important lesson that we flat out ignored. Building a stealth plane in 1943 meant the Germans had learned something it would take us another 30 years to figure out. Stealth is essential in aircraft.

    Instead, we had the likes of unstealthy aircraft flying over Vietnam and getting shot down with rather significant losses to surface to air missiles.

    More than 1700 US aircraft were shot down. That's a catastrophe. It was in response to that that the US Stealth fighter program was initiated in the early 1970s. But, just imagine if we had thought, geez, the Germans had came up with a way to evade radar, we have the plane, newer technology...

      Also, the German technology was mostly serindipitous. Radar cross-section is much more a function of airframe shaping than materials; it just happened that flying wings tended to be better-shaped than traditional aircraft. But all of this was a trial-and-error process. We learned some from this, and incorporated those lessons into the B-70 proposal and the SR-71. However, it wasn't until the F-117 program (and its contemporaries) came along that we had

      C. The control technology to make such shapes flyable.

      And even then, the result was a flat-faceted, ungainly monstrosity. It took a little longer before we could compute reflections of curved surfaces, and develop something like the B-2.

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.

The cost of computation dropped greatly between the F-117 and the B-2, and thus the flat/angular stealth scheme vanished into history. Cell phones had fuck-all to do with it since they wouldn't become common until a decade after this happened.

    "RCS testing showed that an Ho-229 approaching the English Coast from France flying at 550 mph at 50 to 100 feet above the water would not have been visible to Chain Home radar."

    The flying wing was a hugely unstable design [wikipedia.org]. The sole Ho IX V2 crashed on 18 February 1945, after only two hours of flight time. On 5 June 1948, Northrop's YB-49 (their second attempt to build a flying wing after the B-35 was cancelled due to insurmountable technical issues) crashed, killing its pilot and co-pilot Daniel Forbes and Glen Edwards, for whom Forbes and Edwards airforce bases are named. It took until the 80s for them to figure it out and make a success of the B2.

    So, so long as a pilot could buzz the waves at an altitude that would make most pilots of conventional fighters of the era nervous, at the high end of speeds for the era (a good 100mph faster than a P-51 Mustang), before flitting up over the cliffs of southern England (the famed white cliffs of Dover reaching up to 106m, a good 70m over the 100 feet the plane was flying across the channel at), then it could have been invisible to British radar of the time.

    One can only imagine, if production had worked out, the teenagers Germany was strapping in to planes at the time (having lost most of its experienced pilots by that point in the war) would have been doing this on a daily basis.
