Horten 229: What is real, what is exaggeration?

[Tony Kambic]

Thanks Harrison.

I was surprised in reading Sengfelder's book on German Landing Gear, the Ho229 was made using an He177 tail wheel assembly as its nosewheel, and its main gear were modified BF109 gear legs.

Hello Mike,


As a professional researcher, there must be the positive and negative approach to this subject. The British began collecting German technical intelligence during the war using a special team called T-Force, which was not their official military designation. The T stood for Target and they carried a special ID card that allowed them to go anywhere, seize any building, any personnel, documents, prototypes and anything else. The regular soldiers that observed them were unaware of their status and regarded them as thieves.

As a researcher, I must investigate evidence for and against. I cannot be biased. The British produced B.I.O.S. reports detailing their findings along with interrogation information and sometimes, photographs of what they found. The Hortens worked with Dynamit AG regarding certain types of wood bonding adhesives and they used plastics for glider construction. One report described the use of wood and plastics by other aircraft manufacturers. The Americans created their own T-Force which worked along with the British, which meant that C.I.O.S. reports were also published. Here is an example of a report title:


CIOS File No. XXXI-8:

Plastics and Wooden Parts in German Aircraft


Now I have found references to various chemical sealers. One was called "polystal." Its composition was a poly-di-isocyanate resin made by the I.G. Farbenindustrie. It was used for sealing integral wing fuel tanks. Now this was for an all wood wing which was itself bonded together with "Kaurit-W" whose chemical mixture is not described in that report. "Kaurit-WHK" is also mentioned as a bonding agent. It may be a variant mixture of Kaurit-W.


Now the word "stealth" was not used but two reports were issued concerning German work on "radar camouflage." Doing this type of research usually involves years. There were other technical intelligence teams in the field which produced reports: F.I.A.T. or Field Intelligence Agency, Technical: http://digitalcommons.unl.edu/libelecrefmat/6/
The American Counter-Intelligence Corps worked with T-Force but a complete history of the CIC has not been published.

So, answers do not come quickly and diligent research that is totally unbiased must be the standard operating method.

Thanks Mr. West. Very interesting link. Very much appriciated. I have CIOS and FIAT etc.. Only not this Industry Report Index. This reports American Forces were testing captured German equipment, at Wright Field, well before any shooting incidents between US and German forces happened. Six months before Pearl Harbour. Not that is any news now. -Ed

You're welcome.

the Ho229 was made using an He 177 tail wheel assembly as its nosewheel, and its main gear were modified Bf 109 gear legs.

I've seen that reference to the Greif tailwheel many times, and I have always wondered, is it really true? Is that actually an He 177 tailwheel? The Bf 109 main gear I don't doubt, but the scale of that nosegear on the Ho 9 is amazing. Can anybody confirm that it is indeed a He 177 tailwheel? What a monster that airplane must have been, if so...

No luck in finding definitive proof that the He-177 tail wheel was used as the nose gear wheel on the 229 but the link below shows the size of the He-177 tail gear minus the wheel. Quite a beast.

The tire size for the Horton is shown as a Continental 1015 X 350 in drawings.

Hope this helps.

100% the nose gear was in-fact the the tail wheel assembly from an He-177.

Main legs were made from modified Me109 gear parts.

1015x380 Nose Wheel (same as the Ar234V, Do335, Ta154, and Me210 Main Wheels)

740x210 Main Gear Wheel - I think this was only used on the Ho229
